What is the value of x?

Answers

Answer:

x = 14

Step-by-step explanation:

4x + (2x + 6) = 90

6x + 6 = 90

subtract both sides by 6:

6x + 6 - 6 = 90 - 6

6x = 84

divide both sides by 6

6x/6 = 84/6

x = 14

double check:

4*14 + (2*14 + 6) = 90

56 + 28 + 6 = 90

(question in picture)

Answers

Answer:

A and E

Step-by-step explanation:

Example of no solution is 3=5

A) x+5 = x-5

minus five from both sides, x=x-10

minus x from both sides 0=-10 ,This is no solution since 0 does not equal -10

B) 0.5y=0

Divide 0.5 from both sides y=0 , this is not no solution

C) x-7=x-7

add seven to each side x=x+0

minus x from each side 0=0 , which is infinite solutions

D) 9(-1+x)+1=12x+1

Distribute 9 to the numbers in the parenthesis -9+9x+1=12x+1

Add the constants together (-9+1 and then minus one from each side) -9+9x=12x

Minus 9x from each side -9=3x, then divide 3 from each side -3=x, this has a solution.

E) 8+4f=4(3+f)

Distribute 4(3+f) 8+4f=12+4f

Minus 4f from each side 8=12, This is no solution since 8 does not equal 12

The answer is A and E

This morning, Josh's car had 19.22 gallons of fuel. Now, 5.3 gallons are left. How much fuel did Josh use?​

Answers

Answer:

He used 13.92 gallons of gas.

Step-by-step explanation:

19.22-5.3=13.92

Answer:

13.92 gallons

Step-by-step explanation:

To figure this out you need to do 19.22-5.3 because 19.22 is how much fuel you started with and 5.3 is how much you have now. So by subtracting them, you can find the amount of fuel he used. 19.22-5.3=13.92

How many more dollars does Jessica pay for a membership fee than Nancy?

The answer is 10 more dollars
(Y)=4(5)+30
Y=20+30
Y=50
The two equations are
y=5x +40
y=4x+30
Jessica pay $40; Nancy $30

Step-by-step explanation:

Expand by multiplying each term in the first expression by each term in the second expression.

The easy way would be multiplying the first expression by 2x then set those numbers off to the side.

Then multiply the first expression by -3 and set those numbers off to the side as well.

Then add the numbers you put off to the side together.

This should result in: 2x^3 - 3x^2 + 10x^2 - 15x - 8x + 12

Combine the alike terms together

=2x^3 + 7x^2 -23x + 12
