3. Peri earned $27 for walking her neighbor's dog 3 times. If pe the same rate and earned $36, how many times did she wall neigh
Andrei [34K]

Answer:

She walked neighbor's dog 4 times.

Step-by-step explanation:

It is given that:

Peri earned $27 for walking the dogs 3 times.

Unit rate = \frac{27}{3}

Unit rate = $9 per dog

Now,

Peri worked at the same rate and earned $36.

Unit rate = \frac{Total\ earning}{Dogs\ walked}

9 = \frac{36}{d}

d= 36/9

d = 4

Therefore,

She walked neighbor's dog 4 times.

Suppose that in a sequence a2 = 14, a4 = 26, a6 = 38, a8 = 50, and a10 = 62. Which of the following is the explicit formula for
olya-2409 [2.1K]
Seems to be aritmetic
an=a1+d(n-1) is aritmetic
a1=fist term
d=comon difference
n=which term


a4-a2=2d where d is the common difference
26-14=12
12=2d
6=d
so
a2-6=a1
14-6=8

an=8+6(n-1)
expand
an=8+6n-6
an=6n+2

Find the solution by graphing on the same grid:
alex41 [277]
              3x ≤ 5y - 10
       3x - 5y ≤ 5y - 5y - 10
3x - 3x - 5y ≤ -3x - 10
             -5y ≤ -3x - 10
              -5          -5
                y ≥ ³/₅x + 2

       2x - 4y < -6
2x - 2x - 4y < -2x - 6
             -4y < -2x - 6
              -4         -4
                y > ¹/₂x + 1¹/₂
