When substituting y = 5x + 12 into the equation 3x - 2y - 32 = 0 to solve the
system, Jun determines that the value of y is
- a negative fraction only
- a positive fraction only
- a negative integer
- a positive integer
Answers
Answer:
A negative integer
Step-by-step explanation:
3x - 2(5x+12) - 32 = 0
3x - 10x - 24 - 32 = 0
-7x -56 = 0
-7x = 56, x = -8
y = 5(-8) + 12, y = -28

Answers
Answer:
x = 6
Step-by-step explanation:
Assuming the equation is
[tex]\frac{2x+3}{3}[/tex] - [tex]\frac{3x}{2}[/tex] = - 4
Multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions
2(2x + 3) - 9x = - 24
4x + 6 - 9x = - 24
- 5x + 6 = - 24 ( subtract 6 from both sides )
- 5x = - 30 ( divide both sides by - 5 )
x = 6
At a state fair, each person pays $8 for admission plus $2 for each ride. While at the fair, Elizabeth goes on 6 rides. Which expression can be used to find the total amount Elizabeth spends?
Answers
Answer:
The expression is given as:
Total amount = 8 + 2x
Total amount = $20
Step-by-step explanation:
Let the number of rides Elizabeth goes on be represented by x
The expression used to find the total amount =
$8 + $2 × x
= 8 +2x
Elizabeth goes on 6 rides
Total amount =
8 + 2 × 6
= 8 + 12
= $20
solve each system of equations algebraically y= x-6 y= 2x
Answers
Answer: x = -6
Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.
y = x - 6
y = 2x
2x = x - 6 (substitute the y value into the equation)
1x = -6 (subtract x on each side)
x = -6 (1x is basically saying x so you do not need to divide)

• The measure of angle Mis (5 x + 10).
• The measure of angle Ris 55°.
What is the value of x?
Answers
Answer:
x=5
Step-by-step explanation:
If the sum of the measures of angle M and R is 90 degrees, and you know that angle R is 55 degrees, subtract angle R from the total angle. Then, solve for M
90 - 55 = 35
5x + 10 = 35

If Bill works on Saturdays, he earns $9 per hour (h), plus a $10 bonus for working on the weekend. He wrote a Function, f(h) = 9h + 10, to help calculate how much he would earn working different numbers of hours next Saturday. How much will Bill earn for 5 hours and 12 hours?
Answers
Answer:
[See Below]
Step-by-step explanation:
For 5 hours: f(5)
f(5) = 9(5) + 10
f(5) = 45 + 10
f(5) = 55
Bill would work earn $55 if he worked for 5 hours.
For 12 hours: f(12)
f(12) = 9(12) + 10
f(12) = 108 + 10
f(12) = 118
Bill would work earn $118 if he worked for 12 hours.

An airplane can cruise at 570 mph. How far can it fly in 4/3 hours?
Answers
Answer:
The plane can fly 760 miles in 4/3 hours.
Step-by-step explanation:
Given that:
An airplane can cruise at 570 miles per hour.
We have to find the distance travelled by train in 4/3 hours.
Distance = Speed * Time
Distance = [tex]570*\frac{4}{3}[/tex]
Distance = [tex]\frac{2280}{3}[/tex]
Distance = 760 miles
Hence,
The plane can fly 760 miles in 4/3 hours.

An escalator in the mall rises to a platform and makes a 30 degrees angle with the ground. If the platform is 76 feet above the ground, how long is the escalator?
Answers
9514 1404 393
Answer:
152 feet
Step-by-step explanation:
A triangle modeling the situation has the unknown length as its hypotenuse, and the given platform height as the side opposite the angle. The relevant trig function is ...
Sin = Opposite/Hypotenuse
sin(30°) = (76 feet)/(escalator length)
escalator length = (76 feet)/sin(30°) = (76/0.5) feet
escalator length = 152 feet

a particular tree is 18 m tall : a model of it was built with a. scale of 4 cm : 3m how tall is the model.
Answers
Answer:
24 cm
Step-by-step explanation:
We can set up a ratio of 18 m / x cm = 3 m / 4 cm because we know that it's a scale.
Cross multiplying, we get 3x = 72. Divide both sides by 3 and we have x = 24 cm.
We can also consider it by just dividing 18 m by 3 m to find the scale factor, which is 6. We then multiply the 4 cm by 6 to get 24 cm as well.

The values of both x and y can be any real number.
The values of both x and y will be real numbers greater than or equal to 0.
The value of x and y will always be zero
The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.
Answers
Answer:
B - The values of both x and y will be real numbers greater than or equal to 0.
The answer choice that best describes the values of x and y is B - The values of both x and y will be real numbers greater than or equal to 0.
Calculations and Parameters:Given that peaches are being sold for $2 per lb.
If we define x as the number of pounds that you buy, and y as the cost of these peaches, we can write the function:
y = $2*x
Therefore, the best description of the values of x and y is found in option B. The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

Jada and Noah wanted to find the total volume of a cube and a rectangular prism. They know that the prisms volume is 20 cubic units, and they know that the cube has side lengths of 10 units. Jada says the total volume is 27,000 cubic units. Noah says it is 1,020 cubic units. Do you agree with either of them?
Answers
Answer:
Noah answer is the correct answer
Step-by-step explanation:
The solution to the above question is given as:
Total Volume = Volume of the prism + Volume of the cube
Volume of the prism = 20 cubic units
Volume of a cube = (Side length)³
= 10³ = 1000 cubic units
Hence: The total volume =
20 cubic units + 1000 cubic units
= 1,020 cubic units
Therefore, I agree with Noah's answer.
