Answer:
x= 6
Step-by-step explanation:
since the triangle is isosceles we know that opposite sides are equal
[tex]5x+5=35\\\\5x=35-5\\\\5x=30\\\\x=\frac{30}{5}\\\\x=6[/tex]
Answer:
[tex]\boxed {\boxed {\sf x=6}}[/tex]
Step-by-step explanation:
An isosceles triangle has 2 equal base angles and 2 equal legs.
In this triangle, 16 must be the base, because the base angles are adjacent. Therefore, the legs are 35 and 5x+5. They must be equal to each other.
[tex]35=5x+5[/tex]
Solve for the value of x by isolating the variable on one side of the equation.
5 is being added to 5x. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.
[tex]35-5=5x+5-5 \\ 35-5=5x\\30=5x[/tex]
x is being multiplied by 5. The inverse of multiplication is division. Divide both sides by 5.
[tex]\frac{30}{5} =\frac{5x}{5} \\\frac{30}{5}=x\\6=x[/tex]
The value of x is 6.

Henry is purchasing a number of magnets. He wants some idea of how many he can buy. On a coordinate plane, the points (3, 1), (6, 2), and (12, 4) are plotted. Using equivalent ratios, which statements are true about the cost per magnet? Check all that apply. The cost of 2 magnets is $1. The cost of 9 magnets is $3. The cost of 10 magnets is $3. The cost of 4 magnets is $2. The cost of 6 magnets is $2. The cost of 3 magnets is $1. Mark this and return
Answers
Step 1: Find the slope
Every 3 magnets that you buy, you need to pay 1 more dollar. Therefore, if you have 9 magnets, the cost will be 3 dollars. Also, if you have 6 magnets, the cost will be 2 dollars. Finally, if you have 3 magnets, the cost will be 1 dollar. So... the correct options are Options B, E, F

Answers
Answer:
1.2
Step-by-step explanation:
You can see from the point on the graph that when x = -6, y = 1.2
When X is equal to -6, Y is equal to 1.2.
How would the line on the graph below change if the slope and the y-
intercept were multiplied by 3?
Answers
Answer:
A.) The line would shift up and have a y-intercept at 12 and the slope would be -9
Step-by-step explanation:
The y-intercept is where the graph intersects the y-axis. This graph intersects at 4, so if it was multiplied by 3, the new y-intercept would be 12.

Find the value of x. Show your work congruent triangles
Answers
Answer:
x = 8
Step-by-step explanation:
We have a given triangle with two interior angles which are x + 23 and 80°. The third angle of the triangle would be equal to 4x + 17. This is because vertical angles are congruent.
Thus:
(x + 23) + 80 + (4x + 17) = 180
x + 23 + 80 + 4x + 17 = 180
5x + 120 = 180
Subtract - 120 both sides
5x = 180 - 120
5x = 40
Divide both sides by 5
x = 8
A group of friends ate a meal in a restaurant, and the cost of their bill is m. Which expression represents the total amount that they'll pay if they tip 20%?
Question 4 options:
A)

C)
1.2m
D)

because dollars are taxed.
The expression that represents the total amount that they'll pay if they tip 20% will be 0.2 + m, because dollars are taxed. so option D is correct.
What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
When someone asks you to solve an equation, then they usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
It is given that a group of friends ate a meal in a restaurant, and the cost of their bill is m.
We need to find the expression that represents the total amount that they'll pay if they tip 20%.
So we know that,
20% = 0.20
The cost of their bill = m.
The total amount they'll pay including tip = 0.2 + m
Therefore, the expression that represents the total amount that they'll pay if they tip 20% will be 0.2 + m, because dollars are taxed. so option D is correct.

Store B offers the better buy. The difference in Unit cost is 5 cents or $0.05
Step-by-step explanation:
First find the costs per tuna. In Store A: 8 cans cost $7.20. To find the cost of 1 can you have to do $7.20/8 which is 90 cents or $0.90In store B; 6 cans cost $5.10. To find the cost of 1 can do $5.10/6 which is 85 cents or $0.85.Therefore store B is cheaper, and to find the difference cost: Do the larger cost minus the smaller: 90 cents-85 cents= 5 cents or $0.05 as the difference cost

B.) The initial cost is $12,950
C.) Each day the total cost decreases by $12,950
D.) The total cost to produce a part for d days is $12,950
Answers
Answer:
B.) The initial cost is $12,950
Step-by-step explanation:
Given that:
[tex]f(d)=275d+12,950[/tex]
is the function to represent the cost for a company for the production of a part for [tex]d[/tex] number of days.
To find:
What does the value 12,950 represent in the above cost function.
Solution:
The given function contains two parts:
1. One part is multiple of [tex]d[/tex] and
2. Second part is a constant.
Here, [tex]d[/tex] is the number of days.
As [tex]d[/tex] changes, the value also changes but the constant part remains the same.
Therefore, we can conclude that the initial cost for the company is $12,950.

Answer: The first study was an observational study whereas the second was a controlled experiment.
Step-by-step explanation:
A study that record the characteristics of a population by studying individuals in a sample, but does not manipulate variables of interest is known as an operational study. Like in the first study only effects have been noted.
A controlled experiment is an experiment where the variable of interest is directly manipulated by a scientist, in order to test a single variable at a time.
Like in the second study, the subjects were under the control of the experimenter, to test the effect of oil.
The first study was an observational study whereas the second was a controlled experiment.

If 1 inch is 500 miles, then 4 inches is how many miles?
Answers
Answer:
2,000 miles
Step-by-step explanation:
We are given:
[tex]1 inch=500 miles[/tex]
This can be rewritten as:
[tex]\frac{500 miles}{1inch}[/tex]
This is representative of a unit rate, as we have a [tex]1[/tex] in the denominator. To calculate the number of miles in [tex]4[/tex] inches, simply multiply the unit rate by [tex]4[/tex]:
[tex]\frac{500 miles}{1inch}*4=[/tex]
[tex]\frac{2000 miles}{4 inches}[/tex]
This can rewritten as:
[tex]4inches=2000miles[/tex]
Therefore, there are 2,000 miles in 4 inches.
-
We can check our solution by simplifying the fraction [tex]\frac{2000 miles}{4 inches}[/tex] by dividing both [tex]2000[/tex] and [tex]4[/tex] by [tex]4[/tex] to see if we achieve the unit rate:
[tex]\frac{500 miles}{1 inch}[/tex]
Since this is in fact the unit rate, our solution is correct!
