Answer:

M = -2

Step-by-step explanation:

-17 + 62 = -5 (3M - 3) Distribute -5 into the parentheses and combine like terms

45 = -15M + 15 Subtract 15 from both sides

30 = -15M Divide 15 from both sides

M = -2

Susan has a rectangular fence around her swimming pool. The fence she built was 15 ft long, 10 ft wide and 6ft tall. How many sq

Dmitriy789 [7]

Answer:

300 Square feet

Step-by-step explanation:

Susan built a rectangular fence around her swimming pool.

Length=15ft

Width(or Breadth)=10ft

Height=6ft

To solve this, picture a cuboid with the top and bottom open, that is the key to finding the Surface Area of the Fence.

Surface Area of a Cuboid= 2(LW+LH+WH)

However since the top and bottom are open, the Surface Area becomes

Surface Area of the fence= 2(LW+WH)

=2((15X6)+(10X6)

=2(90+60)=2 X 150 =300

Susan uses 300 Square feet to build her fence.

Answer:

40%

Step-by-step explanation:

We are given that last month, Joe's puppy weight 5.4 pounds while this month, the puppy weighed 7.56 pounds.

We are to find the percentage increase of the weight of the puppy

We know that the formula of percentage increase if given by:

Percentage increase = (new value - initial value)/initial value × 100

So substituting the given values to get:

Percentage increase in puppy's weight = $\frac{7.56-5.4}{5.4} \times 100$ = 40%
