Answer:

x=48

Step-by-step explanation:

$5.40(10)+2.50(x)=3.00(10+x)\\\\54.0+2.50x=3.00(10)+3.00(x)\\\\54+2.5x=30.0+3.00x\\\\54+2.5x=30+3x\\\\54+2.5x-2.5x=30+3x-2.5x\\\\54+0=30+(3-2.5)x\\\\54=30+0.5x\\\\54-30=30+0.5x-30\\\\24=0.5x\\\\10(24)=10(0.5x)\\\\240=5x\\\\\frac{1}{5} (240)=\frac{1}{5} (5x)\\\\48=x\\\\x=48$

Sarah ran 2 miles and Jaime ran 15, 840 feet. How many miles did they run together? (The conversion factor is 5280 feet/mile.)

Korvikt [17]

Answer:

C. 5 miles

Step-by-step explanation:

Since we need to find how many miles they ran together, let us convert feet to miles. Sarah's length is already in miles so we'll leave it that way.

Jaime ran 15840 feet. We are given how many feet are there in one mile (5280), so we need to find how many miles are there in 15840 feet.

x = 15840 / 5280 = 3 miles.

So, Jaime ran 3 miles and Sarah ran 2 miles.

That means that together they ran 3 + 2 = 5 miles.
