Inessa [10]

Answer:

a = 2(b) + 4.

Step-by-step explanation:

Part A: $11 + a = b. A= the extra money he got for walking the dog. B= the total money for walking the dogs.

Part B: a = 2(b) + 4. I did + 4 because it says “Larry was able to walk 4 more than twice as many dogs as his friend Kyle”. This equation would work because a = Larry and b = Kyle, so Larry has 2 times the amount as Kyle plus the 4.

I hope this helps <3

The Sommers invested $5000 for three years at 6.5%. How much interest did the investment earn in three years? What was the total
Jet001 [13]

Answer:

the interest is $975

the total amount  is $5975

Step-by-step explanation:

lets use tje formula

I=PRT

where I is interest earned

P is the principal amount(original amount)

R is the rate of interest

and T is the time in years

so

the principal amount is 5000 since it is the original amount

rate is \frac{6.5}{100}=0.065

time is 3 years

lets plug these values into our equation:

5000*0.065*3=I

5000*0.065*3=975

the interest is $975

the next part of the question is asking for the balance or the total amount which is principal+interest

5000+975=5975

the total amount or balance is $5975

hope this helps

Which ordered pair in the form (x, y) is a solution of this equation?
Natasha2012 [34]

(3, 1)

substitute each ordered pair into the left side of the equation and if equal to the right side then it is a solution

(4, 1 )

(4 + 6) × 1 = 10 × 1 = 10 ≠ 9 ← not a solution

(2, 1 )

(2 + 6 ) × 1 = 8 × 1 = 8 ≠ 9 ← not a solution

(3, 1 )

(3 + 6 ) × 1 = 9 × 1 = 9 ← hence a solution

(12, 2 )

(12 + 6 ) × 2 = 18 × 2 = 36 ≠ 9 ← not a solution
