Below are the steps to solve an equation:

1 answer:

8 0

The only answer is choice A) x-4 = -7

The rule is that if |x| = k, for some positive number k, then x = k or x = -k

Based on this rule, the absolute value equation
|x-4| = 7
breaks down into these two equations
x-4 = 7 or x-4 = -7

A rectangular pool is 12 ft wide, 20 ft long and 5 ft

S_A_V [24]

Multiply the 3 dimensions to find the volume, then find 4/5 of the volume by multiplying 4/5 by the volume.

12x5=60

60x20=1,200

I'm gunna convert the 4/5 to decimal to make it easier.

1,200x0.8=960

So there is a total liquid volume of 960(I'm assuming it's ounces).

The city park is 9 and 2/5 km from Roland Public School. The city library is 3 and 3/10 km from the same school. How much farthe

Marina86 [1]

Answer:

6 1/10

Step-by-step explanation:

Convert the mixed numbers into improper fractions (denominator × whole number + numerator / denominator):

9 2/5 = 47/5

3 3/10 = 33/10

Convert improper fractions to have the same denominator:

47/5 × 2/2 = 94/10

Find the difference by subtracting the numerators:

94/10 - 33/10 = 61/10

Convert the answer into a mixed number:

61/10 = 6 1/10

PQRS is a parallelogram. If mQRS = (9x - 20)° and

ivolga24 [154]

Answer:

x = 8.5

Step-by-step explanation:

In this question, we are to calculate the value of x.

To calculate this, we shall be utilizing one of the important properties of parallelogram.

This property is that opposite angles of a parallelogram are equal.

This means that mQSR = mSPQ = 4x + 90

Now to finally calculate x, we make use of another important parallelogram property which is that angles of parallelogram which faces each other are supplementary.

This means that they add up to be 180

Since mQSR faces mQRS

This means that;

4x + 90 + 9x -20 = 180

13x + 70 = 180

13x = 110

x = 110/13 which is approximately 8.5

Finger [1]

Are you saying that every chimpanzee is a mother? If so, then each chimpanzee would have a baby 7 times in 28 years, meaning there would be 49 chimpanzees.

If you mean just one, then only 7 babies in 28 years.

Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub. What is the area

harkovskaia [24]

Answer:

The area of the cover for the hot tub must be:

38 square feet.

Step-by-step explanation:

First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle:

Area of a circle = pi * radius ^ 2 (you must know that the radius is half the diameter)

Since the diameter is mentioned, it can be replaced in the formula:

Area of a circle = 3.14 * (3.5 feet) ^ 2
Area of a circle = 38,465 square feet. Approximately 38 square feet.
