Answer:
A) 2 + 8x = -134
B) x = -17
Step-by-step explanation:
Note: I am assuming the question says use x as a variable, not z. Otherwise part B does not make sense
If we let variable x be the number then
8 times a number ==> 8x
2 and 8 times a number ==> 2 + 8x
2 and 8 times a number is -134 ==> 2 + 8x = -134
A) Equation form is 2 + 8x = -134
B) Equation is
2 + 8x = -134
Subtract 2 from both sides:
2 - 2 + 8x = -134 - 2
8x = -136
Divide both sides by 8 to give
8x/8 = -136/8
x = - 17
what is 1150in hectares and in m2
Answer:
The answer is 11500000 Square Meters
Answer:
11,500,000
Step-by-step explanation:
To convert 1150 hectares to square meters, we need to multiply it by 10,000. Therefore, 1150 hectares is equal to 11,500,000 square meters. It is important to note that one hectare is equal to 10,000 square meters. So, 1150 hectares is equivalent to 11,500,000 square meters or 11,500,000 square meters. This conversion is useful when measuring large areas of land, such as agricultural fields, forests, and parks.

Find the Least Common Denominator of 5/6 and 3/8, show all of your work:
To find the LCD of (5/6, 3/8) we need to find the Least Common Multiple (LCM), which in this case is (6, 8). So we want to find the values of the numerical part of each term. We need to select the largest one, which in this case is 8
Then multiply them together to get the current total. In this case, the current total is 48
Current Total = 48
Multiply the numeric part of the denominators together.
Current Total = 8 + 8 = 16
Again, multiply the numeric part of the denominators together.
Current Total = 16 + 8 = 24
Check each value in the numerical part of each term against the current total. Since the current total is evenly divisible, return it. That is the least common denominator of the numerical part of the fraction.
So the Lowest Common Denominator (LCD) is 24

The manufacturing cost of a cell phone was $136. Sellers first marked up the cost by 25 percent. Sales were poor, so sellers decreased the markup to 17 percent. Calculate the old and new selling prices.
Answer:
old price was $170; new price is $159.12
Step-by-step explanation:
1) Formula given:
Selling price = original cost + mark up value
2) Old price = original cost + 25% (original cost)
Old price = $136 + 35% ($136) = $136 + 0.25×$136 = $136 + 34 = $170
3) New price = original cost + 17% (original cost)
= $136 + 17% ($136) = $136 + 0.17×$136 = $136 + $23.12 = $159.12
Answer:
old price was $170; new price is $159.12
A truck can be rented from Company A for $70 a day plus $.5 per mile. Company B charges $30 a day plus $.9 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
100 miles in a day the truck should have to cover so that the rental costs for company A and company B are same
Company A rented a truck for $70 a day and $.5 per mile will be added accordingly. Similarly, Company B rented a truck for $30 a day and $.9 per mile will be added as per distance covered.
Let the number of miles travelled by the truck be x.
Then, we can depict the given information in terms of equation and will equate them further to solve according to the question need.
So, total rent to be pay to company A = $(70+0.5x)
and total rent to be pay to company B = $(30+0.9x)
Now, the number of miles in a day at which the rental costs for Company A and Company B are the same will be
70+0.5x = 30+0.9x .............(1)
Now, solve equation (1) in order to calculate the value of x.
70-30 = 0.9x-0.5x
40 = 0.4x
40/0.4 = x
400/4 = x
100 = x
∴ x = 100
Hence, 100 miles in a day the truck should have to cover so that the rental costs for company A and company B are same.

Write the statement "the sum of a number and 12.6 is more than −3.5" as an inequality.
−3.5 + b ≥ 12.6
−3.5 + b < 12.6
b + 12.6 > −3.5
b + 12.6 ≤ −3.5
Answer:
c
Step-by-step explanation:
For the given statement "the sum of a number and 12.6 is more than −3.5" the inequality is b + 12.6 > −3.5. Option C is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.For the inequality, we have to apply the arithmetic operation.
It is given that the sum of the number 12.6 is more than −3.5.
If the two numbers are b and 12.6 their sum is represented as b + 12.6 and the sum of the number is more than −3.5.
The obtained relation in form of inequality is,
b + 12.6 > −3.5
When we are unsure if the value of a variable is greater than a specific value, we use the "Greater than " symbol in linear inequalities. It is represented by the character ">"
Thus, for the given statement "the sum of a number and 12.6 is more than −3.5" the inequality is b + 12.6 > −3.5. Option C is correct.

3 x 1, 250 expanded form
The Expanded form of 3×1=3 is 3
The Expanded form of 250 is 200+50+0
Expanded form is nothing more than a method for rewriting a number such that the digit values are included. A place value exists for each number. It calculates that digit's value based on where it is in the number. As we move from left to right in a number, a digit's value rises. In comparison to the digits on the right, the ones on the left have a lower place value. The position of the number is used to calculate each number's value. We can comprehend the place value notations if we read them from right to left.
250=200(hundreds place)+50(tens place)+0(ones place)
Therefore, the Expanded form of 250 is 200+50+0.

The ratio of mammals
to reptiles at the pet
I store is 3:7. If there are
90 animals at the pet
I store, how many of the
animals are reptiles?
Show answer in a ratio table
The number of reptiles will be 63.
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the ratio of lemons to oranges is 6:8 (or 3:4) and the ratio of oranges to the total amount of fruit is 8:14 (or 4:7).
The numbers in a ratio may be quantities of any kind, such as counts of people or objects, or such as measurements of lengths, weights, time, etc. In most contexts, both numbers are restricted to be positive.
Let the number of mammals and reptiles be 3x and 7x
the store has total 90 animals
so total number of animals will be
90= 3x+7x
90= 10x
so x will be 9
number of mammals will be 3×9= 18
number of reptiles will be 7×9= 63.

Step-by-step explanation:.
area of a circle s pier^2 or just 1/2pie r^2 so 1/2*3.148*2answer is 37.68.if the length of a rectangle is four less than twice its width and the perimeter is 220 inches, what is the width of the rectangle?
Answer:
Let's denote the length of the rectangle to be L and the width to be W.
The first sentence tells us that the length, L, is "4 less than twice the width". "4 less than" implies we subtract 4 from some quantity. What is that quantity? Well that's "twice the width." We can rewrite this sentence in terms of L and W as: L = 2W - 4.
Now we know the length of the rectangle in terms of the width.
The area of a rectangle is given by A = L x W. Using this equation, we can substitute our values for area and length:
A = L x W
96 = (2W - 4) x W
From this we can solve for W and subsequently solve for L using algebra:
96 = (2W - 4) x W
96 = 2W^2 -4W
96 = 2(W^2 - 2W)
48 = W^2 - 2W
W^2 - 2W - 48 = 0
(W - 8)(W + 6) = 0
W = 8 or W = -6
Since W is the side-length of a rectangle, we can disregard the negative solution. Therefore W = 8 ft.
If W = 8, then L = 2W - 4 = 2(8) - 4 = 12 ft.
Lastly, we know the Perimeter of a rectangle is given as P = 2L + 2W. Substituting into this equation we solve for the perimeter:
P = 2L + 2W = 2(12) + 2(8) = 40 ft.
Step-by-step explanation:
