Answer:
12
Step-by-step explanation:
Let's put the equations in standard form. For the first equation, we have:
−11y=6(z+1)-13y
2y−6z=6
y−3z=3
The second equation is:
4y−24=c(z−1)
4y−cz=24−c
If we multiply the first equation by 4, we get:
4y-12z=12
Comparing the two equations, we see that if c=12, both equations will be the same and there will be infinitely many solutions.
The correct value of c is 12.

Leah's rectangular driveway is 48 feet long and 14 feet wide. With sidewalk chalk, Leah drew a straight diagonal line on her driveway from one corner to the opposite corner.
How long is the diagonal line Leah drew?
25 feet
46 feet
50 feet
62 feet
[tex]48^2+14^2=x^2\\x^2=2500\\x=50[/tex]
The length of the diagonal drawn by Leah will be 50 feets
Given the Parameters :
Length = 48 feet Width = 14 feetsThe length of the diagonal is the value of the hypotenus in a right angles triangle :
Let the length of the diagonal = d
d = √(length)² + (width)²
d = √48² + 16²
d = √2304 + 256
d = √2560
d = 50.5961 feets
Therefore, the closest value for the length of the diagonal in the options given is 50 feets

what is the volume of the rectangular prism
It is all the numbers multiplied together. 135
Answer:
[tex]\Huge\boxed{D.135 cm^3}[/tex]
Step-by-step explanation:
Hello There!
We can find the volume of the figure by using the formula for volume of a rectangular prism
[tex]V=lwh[/tex]
where l = length, w = width and h = height
we are given all of the dimensions so all we have to do is plug in the values
so
V = 3 x 9 x 5
3x9=27
27x5=135
so the volume of the rectangular prism is 135 cm³
7x-9x=-36

Last month, Kira spent 15 hours watching T.V. And 12 hours reading. During the same month, Charlie spent 20 hours watching T.V. And 16 hours reading. Who had a higher ratio of time spent watching T.V. To time spent reading? A. Kira B.Charlie C.Neither; the ratios are equivalent
Answer: C.Neither; the ratios are equivalent
Step-by-step explanation:
Kira spent 15 hours watching T.V and 12 hours reading. The ratio of time spent watching T.V. to time spent reading will be:
= 15/12
= 5/4
= 5:4
Charlie spent 20 hours watching T.V. and 16 hours reading. The ratio of time spent watching T.V. to time spent reading will be:
= 20/16
= 5/4
= 5:4
Therefore, they have equivalent ratio

A triangle has a base length of 14cm. The perpendicular height is 9cm. Find the area of the triangle
The area of a triangle with the given base and height is 63 cm².
Given that, a triangle has a base length of 14 cm and the perpendicular height is 9 cm.
What is the area of a triangle?The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Here, b=14 cm and h= 9 cm
So, area = 1/2 × 14 × 9
= 63 cm²
Therefore, the area of a triangle with the given base and height is 63 cm².

150/0.1
= 1500
So, Kelly made $1,500 before taxes
Answer:
$1,500
Step-by-step explanation:
Turn 10% into a decimal: To turn a percent into a decimal, you move the decimal twice to the left.
10%=.1
Divide: $150 divided by .1=1500
$1,500
