Make ratios.
12/16: 15/x
cross multiply
12(x) = 12x
16(15) = 240
12x = 240
isolate the x, divide 12 from both sides
12x/12 = 240/12
x = 20
D) 20 km is your answer

The US to euros is 1: 0.7716,
The euros to Polish is 1:4.0518
0.77 4.05 0.77 1 0.77
----- / --------- = ------- x ---- = ------
1 1 1 4.05 4.05
(so for every 0.77 dollars it is 4.05 zolty.)
hope this helps
sorry if it is confusing
Answer:
x= 6/7 or x = −10/7
Step-by-step explanation:
Let's solve your equation step-by-step.
4(|7x+2|)=32
Step 1: Divide both sides by 4.
4(|7x+2|)/4 =32/4
|7x+2|=8
Step 2: Solve Absolute Value.
|7x+2|=8
We know either 7x+2=8 or 7x+2=−8
7x+2=8 (Possibility 1)
7x+2−2=8−2 (Subtract 2 from both sides)
7x/7 = 6/7
(Divide both sides by 7)
7x/7= 6/7
x= 6/7
7x+2=−8 (Possibility 2)
7x+2−2=−8−2 (Subtract 2 from both sides)
7x/7 = −10/7
(Divide both sides by 7)
x= −10/7
Answer:
x= 6/7 or x = −10/7

Answer:
D
Step-by-step explanation:
If the scale is 1 centimeter per 8 miles, and there is a distance of 51.5 centimeters on the map, what you have to do is multiply 51.5 and 8
51.5 times 8 is 412.
The actual distance is <u>412 miles</u>
