Please simplify this
-3(2+6x) +7x

Answers

Answer 1

Answer:

x = -17

Step-by-step explanation:

To simplify, we need to solve within the parentheses first:

-3(2 + 6x) + 7x

(-6 - 18x) + 7x

Next, we combine like terms:

-6 - 18x + 7x

-6 - 11x

Next, we isolate the variable "x":

-6 - 11x

/x

-6 - 11 = x

Combine like terms:

x = -17

Hope this helps :)

Find the value of y = 500 -25x
for x = { -3, 2, 5}

Answers

Answer:

575, 450 and 375

Step-by-step explanation:

Find the value of y = 500 -25x

for x = { -3, 2, 5}

Given the function y = 500-25x

When x = -3.

y = 500-25(-3)

y = 500+75

y = 575

When x = 2

y = 500-25(2)

y = 500-50

y = 450

When x = 5

y = 500-25(5)

y = 500-125

y = 375

Hence the required values are 575, 450 and 375

Akira and Hideo are twins with different jobs. Akira earns five-eighths of what Hideo earns, but Akira's expenses are half of Hideo's. Akira ends up saving 40% of his income. What percentage of his income does Hideo save?

Answers

Answer:

25%

Step-by-step explanation:

Let x represent Akira income and let y represent Hideo income.

Since Akira earns five-eighths of what Hideo earns, therefore Akira income is given by:

x = (5/8)y

Let a represent Akira expenses and let y represent Hideo expenses. Since Akira expenses is half of Hideo, hence:

a = (1/2)b; b = 2a

Given that Akira savings is 40% of his income, we have:

savings = income - expenses

40% of x = x - a

a = x - 0.4x

a = 0.6x

For Hideo:

Income = y, expenses = b = 2a

Savings = income - expenses

Savings = y - 2a

Savings = y - 2(0.6x) = y - 1.2x

Savings = y - 1.2(5/8)y

saving = y - 6y/8

savings = 2y/8 = 0.25y

Therefore Hideo saves 25% of his income

What is 62% written as a decimal?

Answers

Answer:

62% = 0.62 in decimal form. Percent means 'per 100'. So, 62% means 62 per 100 or simply 62/100. If you divide 62 by 100, you'll get 0.62 (a decimal number).

The decimal of 62% is 0.62

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. With the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

We have to change 62% in decimal.

As, 62%

= 62/100

And, the number of zeroes in denominator decimals where to put the decimal.

so, 62/100

= 0.62

Which expressions are equivalent to − 90 − 60 w?

Answers

Answer:

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Using distributive property:

A : -30(3+2w)  =  -90 - 60w          : equivalent to -90 - 60w

B : (-9-6w) ⋅ 10  = -90 - 60w          : equivalent to -90 - 60w

C : -3(30 - 20w)  = -90 + 60w       : NOT equivalent to -90 - 60w

D : (6 + 4w)×15  = 90 + 60w          : NOT equivalent to -90 - 60w

E : −20(4.5 + 3w) = - 90 - 60w     : equivalent to -90 - 60w

SO THAT MEANS

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)
