<em><u>Answer:</u></em>
<em><u>y = 5, 3; x = 171, 155</u></em>
<em><u>Step-by-step explanation:</u></em>
8y - 15 = y^2
y^2-8y+15=0
y^2-3y-5y+15=0
y(y-3)-5(y-3)=0
(y-5)(y-3)=0
y can be 5 or 3.
x = 180 - (8y - 15)
x = 180 - (8(3)-15)
x = 180 - 9
x = 171
OR
x = 180 - (8(5) - 15)
x = 180 - 25
x = 155
Answer:
Age
Step-by-step explanation:
it is about them.
If it were how many siblings they have it, then would not be just about them.
If it were there sport it would not be about them it would also be about sports
1/3 chance of getting a cracked egg
Answer:
5 inches
Step-by-step explanation:
The volume of a cone formula is V = (1/3)(base)(height). Thus, 3V =(base)(ht).
We want to calculate the height of the cone. Divide both sides of
3V =(base)(ht) by (base), obtaining 3V/(base) = ht.
Substituting 12 in^3 for V, and 2.25pi for (base), we get:
12 in^3
------------ = 5.33 in, or, to the nearest inch, 5 inches.
2.25 pi
Note: The diameter of the cone is 3 inches. The area of the base is pi*r^2, so we must divide d = 3 inches by 2 to obtain the radius: 1.5 in. Then r^2 = 2.25 in^2.
Answer:
NO
Step-by-step explanation:
Given the system of equation
-x+4y = -9,... 1
y = -2x+6.... 2
To find the solution to the equation
Substitute equation 2 into 1
-x+4(-2x+6) = -9
-x-8x+24 = -9
-9x= -9-24
-9x = -33
x = 33/9
Find y
y = -2x+6
y = -2(33/9)+6
y = -66/9 + 6
y = -66+54/9
y = -12/9
y = -4/3
Hence (2,3) is not the solution to the system of equation
