Solve for x -2^2(-5x+10)=100

Mathematics
1 answer:
masha68 [24]3 years ago
3 0

Answer:

x=7

Step-by-step explanation:

Hi there!

-2^2(-5x+10)=100

Solve -2^2:

-4(-5x+10)=100

Divide both sides by -4:

\displaystyle \frac{ -4(-5x+10)}{-4}=\frac{100}{-4} \\\\-5x+10=-25

Subtract 10 from both sides:

-5x+10-10=-25-10\\-5x=-35

Divide both sides by -5:

\displaystyle \frac{-5x}{-5} = \frac{-35}{-5} \\\\x=7

Therefore, x = 7.

I hope this helps!

Alice is saving money at a constant rate. Suppose she initially has $70 saved, and after 2 months, she has $170 saved.
timofeeve [1]

Answer:

50 dollars per month

Step-by-step explanation:

Given

Months = 2

Total = 170

Initial = 70

Required

Determine the rate of savings

Suppose in a month, she saves x amount.

In 2 months, she would save 2x

When 2x is added to the initial savings, it gives the total amount saved.

So, we have:

2x + 70 = 170

Collect Like Terms

2x = 170 - 70

2x = 100

Divide both sides by 2

x = \frac{100}{2}

x = 50

<em>Hence, she saves $50 dollars monthly</em>

A landscaper is creating a rectangular flower bed such that the width is half of the length . the area of the flower bed is 34 square feet . write and solve the equation determine the width of the flower bed , to nearest tenth of floor .

Answer :

it says that width is half the length . which also implies that length is double the width . as we shift the 2 from denominator , it gets multiply on RHS

let the length be 2x

and

width be = x

length × breadth = 34

2x × x = 34

2x^2 = 34

{x}  =  \sqrt{34}

x = width = 5.8309518948
