If 8x−5y=−3 is a true equation, what would be the value of 8x−5y+7?

Answers

Answer 1

Answer:

Value of 8x -5y + 7 is 4.

Step-by-step explanation:

Given that:

8x-5y = -3 Eqn 1

It is a true equation.

Now we have to find the value of the given expression

8x -5y + 7

Putting value of 8x-5y from Eqn 1 in the given expression

8x - 5y + 7

-3 + 7

Therefore,

8x - 5y + 7 = 4

Hence,

Value of 8x -5y + 7 is 4.

1) From 30 inches to 24 inches. What is the percent of change? A. Increase 20% B. Decrease 25% C. Increase 20% D. Decrease 20%

Answers

Answer:

either d or b???

It’s clearly a decrease, since it goes form a higher number (30) to a lower one (24).
30-24 = 6
6/30 = x/100
Work:
6 x 100 = 600
600/30 = 20

So there’s a 20% decrease.

The price of gas was $2.49 last month. This month, gas costs $2.79. What is
the percent increase?

Answers

2.79 - 2.49 = .30

then divide the amount increased by the original number and multiply by 100

.3 / 2.49 x 100 = 12%

Answer:

12%

Step-by-step explanation:

2.79 - 2.49 = $0.30

0.30 / 2.49 = 0.12 = 12% (decimal changes to percent)

You can check your work by doing original cost times the decimal of the percent increase. $2.49 * 0.12 = $0.30. Add this to original -> 0.30 + 2.49 = $2.79.

1138 in expanded form

Answers

One thousand one hundred thirty eight

Answer:

(see below)

Step-by-step explanation:

To put 1138 in expanded form, you should first know that expanded form is separating a number into its place values. Here's what I'm talking about:

1 in expanded form is 1.

11 in expanded form is (10 + 1).

111 in expanded form is (100 + 10 + 1).

So that means that:

1138 in expanded form is (1000 + 100 + 30 + 8).

They're vertical angles, so they are equal:

5x + 4 = 49

subtract 4 from both sidese

5x = 45

divide both sides by 5

x = 9

Answer: x=9

Step-by-step explanation: First of all, the two shown inner angles are equivalent. This allows you to set up an equation like: (5x+4)=49

Then simply use algebra to solve...

(5x+4)=49

-4 -4 (subtract "4" from each side)

5x=45

5x/5=45/5 (divide each term in the equation by "5")

x=9

Step-by-step explanation:

6x^2 - 27x = 0 (original)

3x(2x - 9) = 0 (factor out GCF of 3x)

(solve each factor (3x and 2x - 9) for x)

3x = 0

x = 0

2x - 9 = 0

2x = 9

x = 9/2
