Divide 33 Photos into two groups so the ratio is 4 to 7

Harman [31]

The ratio of group 1 to group 2 to total is 4:7:11.

4:7:11= x:y:33

11*3=33
Multiply the other numbers by 3 to get the answers for x and y.
x= 4*3=12
y= 7*3=21

Final answer: Group One-12, Group Two-21

If a rectangle's length is 10 more than 3 times the width and the perimeter is 36. what are the dimensions?

Archy [21]

L=3W+10 and P=2(L+W)=36

36=2(3W+10+W)

36=8W+20

8W=16

W=2 and since L=3W+10=16

W=2 and L=16

Does anyone seriously know how to do these

mr Goodwill [35]

Thats simple!
h(x)= $\frac{x^{2}+3x }{4x+27}$
find h(-8)
All we need to do is PLUG IN THE -8
h(-8)= $\frac{(-8)^{2}+3(-8) }{4(-8)+27}$
= $\frac{64-24}{-32+27}$ (negative²=positive, negative×positive=negative)
= $\frac{40}{-5}$
h(-8)=-8
