352 ft is ____ % of 2 mi; 2 mi is ____ % of 352 ft
Alexus [3.1K]

Answer:

352 ft is <u>3.34</u>% of mi ;

2 mi is <u>3000</u>% of 352 ft

Step-by-step explanation:

To calculate : 352 ft is ___% of 2 mi and 2 mi is ___% of 352 ft.

We can calculate first:

352 is x% of 2 mi.

Solve for x;

Use conversion:

1 mi = 5280 ft

2 mi = 10560 ft

x% of 10560 ft means \frac{x}{100} \times 10560 = 105.60 x

then, our equation become;

352 = 105.6 x

Divide both sides by 105.6 we get;

x = 3.333333...

or

x ≈3.34

Similarly, for

2 mi is y% of 352 ft

Solve for y;

2 mi = 10560 ft

y% of 352 = \frac{y}{100} \times 352 = 3.52y

then;

10560 = 3.52 y

Divide both sides by 3.52 we get;

y = \frac{10560}{3.52}

y = 3000

Therefore; 352 ft is 3.34% of mi ; 2 mi is 3000% of 352 ft

3. x + 4y = 30<br> x - 2y = 0
kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10
