Answer: n= 0

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8n−6(−5n−3)=18+7n

8n+(−6)(−5n)+(−6)(−3)=18+7n(Distribute)

8n+30n+18=18+7n

(8n+30n)+(18)=7n+18(Combine Like Terms)

38n+18=7n+18

38n+18=7n+18

Step 2: Subtract 7n from both sides.

38n+18−7n=7n+18−7n

31n+18=18

Step 3: Subtract 18 from both sides.

31n+18−18=18−18

31n=0

Step 4: Divide both sides by 31.

31n /31  = 0 /31

n=0

Answer:

n=0

Are these two expressions equivalent? Use the
Rina8888 [55]

Answer:

No, they are not equivalent

Step-by-step explanation:

8x + 3(x + y)

8x + 3x + 3y

11x + 3y

7x + 7y + 4x + 4y

11x + 11y

They are not equivalent because in one of the equations, the like terms add up to 11y which is different from the other equation which adds up to 3y.

I hope this helps.

vazorg [7]

Answer:

n = 8

Step-by-step explanation:

Continuing the sequence using

x_{n} + x_{n+1}

x₄ = x₂ + x₃ =1 + 2 = 3

x₅ = x₃ + x₄ = 2 + 3 = 5

x₆ = x₄ + x₅ = 3 + 5 = 8

x₇ = x₅ + x₆ = 5 + 8 = 13

x₈ = x₆ + x₇ = 8 + 13 = 21

x₉ = x₇ + x₈ = 13 + 21 = 34

x₁₀ = x₈ + x₉ = 21 + 34 = 55 ← with n = 8

13. Estimate how much money Jonah will make in an 8hr work day if he makes $7.59 per hour but 10% must go to taxes. Please show
attashe74 [19]

The hourly rate of $7.59 per hour multiplied by hours gives the gross wages earned. If 10% are taken for taxes then 90% are take home wages.

(0.9)*(8 hr/day) * (7.59 $/hr ) = 54.65 $/day take home pay
