Answer:

You have to destructive the -4 to the inside numbers so it would be -4x-20+8x=48

Then you add -4+8=4

4-20=48

-16=48

Divide both sides by -16

X=-3

Answer:

Step-by-step explanation:

-4(x+5)+8x=48

Opening bracket

-4x - 20 + 8x = 48

Collecting like terms

4x = 48 + 20

4x = 68

x = 68/4

x = 17

The length of a rectangle is 5 inches more than the width. The area is 33 square inches. Find the length and width . Round to th
EleoNora [17]

Answer:

the length and width . Round to the nearest tenth are 8.8 inches and 3.8 inches respectively.

Step-by-step explanation:

The area A of a rectangle is the product of the length L and width W. This may be expressed mathematically as

A = L * W

As such, given that the length is 5 inches more than the width,

L = W + 5

33 = W(W + 5)

W² + 5W  - 33 = 0

Using the formula method which states that

s = -b±√(b²-4ac)/2a

W = -5 ± √5² - 4(1)(-33)/2

= -5 ± 12.53/2

= 7.53/2 (since length cannot be negative)

= 3.755 inches

L = 3.755 + 5

= 8.755 inches

A science teacher has a supply of 50% sugar solution and a supply of 80% sugar solution. How much of each solution should the te
mash [69]
How much of each solution should the teacher mix together to get 105 ML of 60% sugar solution for an experiment?

1. Look at how 60% is closer to the solution of lower concentration (50%). You can deduce that you will be mixing a higher volume of the 50% solution.

2. All 4 answers add up to 105ml.

3. The intuitive answer is the first option:
70 ML of the 50% solution and 35 ML of the 80% solution

4. Let's check whether point 3 is true.
70ml/105ml X 0.5 + 35ml/105ml X 0.8 = (35 + 28)/105= 63/105= 60% / 105 ml = 105ml of 60% sugar solution

In isosceles triangle ABC, AB=AC.If B=55, calculate A​
den301095 [7]

Answer: ∠A = 70°

because ABC is an  isosceles triangle and AB =  AC

=> ∠B = ∠C = 55°

=> ∠A = 180-(∠B + ∠C) = 180° - 55°.2 = 70°
