1) $375
500 *.25= 125
500-125= 375
2) (5/8)* 32= 20 girls in class
(3/8)* 32= 12 BOYS in class
4) 19+42+X=87
62+X= 87 (add 19 and 42 together )
X=25 ( subtract 87 from 62)
Answer:
C) (6,2)
Step-by-step explanation:
Rewrite equations:
y=x−4;x+2y=10
Step: Solve y=x−4for y:
y=x−4
Step: Substitute x − 4 for y in x+2y=10:
x+2y=10
x+2(x−4)=10
3x−8=10(Simplify both sides of the equation)
3x−8+8=10+8(Add 8 to both sides)
3x=18
3x
3
=
18
3
(Divide both sides by 3)
x=6
Step: Substitute6forxiny=x−4:
y=x−4
y=6−4
y=2(Simplify both sides of the equation)
Hope this helps!

Answer:
a=28
Step-by-step explanation:
use inverse operations
Answer:
1 True
2 c>−4
3 x< 3/2
Step-by-step explanation:
5s+s= -48
⇒ 6s = -48
⇒ s= -48/6
⇒ s= -8.
The final answer is s=-8~
