Answer: -35.375 or -283/8

Step-by-step explanation:

Begin with the parenthese: (-1.5+9.5)=8 and (7+11)

Then you have 5/8+0.4(18)/-0.2.

Multiply 0.4 times that 18 and you get 7.2.

Then you have 5/8+7.2/-0.2

Simplify 7.2/-0.2 which equals -36

Then you have 5/8+-36

5/8+-36=-35.375 or in fraction form -283/8

You are resurfacing your backyard pool. The pool is in the shape of a rectangular prism with a length of 20 ft, a width of 10 ft

zepelin [54]

Answer:

$440\ ft^2$

Step-by-step explanation:

we know that

The area of the backyard pool to be resurfaced is equal to the area of the base plus the area of its four lateral sides.

$A=B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the depth of the pool

Find the area of the base B

$B=(L)(W)$

substitute the given values

$B=(20)(10)=200\ ft^2$

Find the perimeter of the base P

$P=2(L+W)$

substitute the given values

$P=2(20+10)=60\ ft$

we have

$H=4\ ft$

Find the area of the backyard pool to be resurfaced

$A=B+PH$

substitute the values

$A=200+60(4)$

$A=440\ ft^2$

Use the distributive property to solve the equation 3.2 = 4/5 (b - 5)

djyliett [7]

Answer:

b=1

Step-by-step explanation:

$3.2 = \frac{4}{5} (b - 5)\\3.2 = \frac{4}{5}b - \frac{4}{5} *5\\3.2 = \frac{4}{5}b - 4\\3.2 = -3\frac{1}{5}b\\3.2 = -3.2b\\1 = b\\b= 1$
