I’m really bad at math can someone me? ?

b = 24

Step-by-step explanation:

-5 + 3/4b = 13

Add 5 to each side

3/4b = 18

Now, we know that 3/4 = 0.75, so divide each side by 0.75

b = 24

We can also plug this into the equation to check it.

-5 + 3/4(24) = 13

3/4(24) = 18

-5 + 18 = 13

13 = 13

Answer is 24

Step-by-step explanation:

Multiply by the l.c.m which is 4.

-20+3b = 52

3b = 52+20

3b = 72

b = 24

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

it has changed from the width and the height.
