Answer:
( 7 , 4 )
given:
make y the subject in equation 2:
4x - y = 24
-y = 24 - 4x
y = 4x - 24
insert this in equation 1:
4x + 10y = 68
4x + 10(4x - 24) = 68
4x + 40x - 240 = 68
44x = 68 + 240
44x = 308
x = 7
solve for y:
y = 4x - 24
y = 4(7) - 24
y = 4
Answer:
11 > (w- 4)
y < 3
5 + 9 < 5.9
So these are the phrases which are inequalities.
Answer:
The answer to your questions radius = 14 in
Step-by-step explanation:
Data
Circumference = 28π in
radius = ?
Circumference is defined as the distance around the edge of a circle.
Formula
Circumference = 2π radius
-Solve for radius
radius = Circumference /2π
-Substitution
radius = 28π / 2π
-Simplification
radius = 28/2
-Result
radius = 14 in
I would have 144 because you just times 4 and 36
