Answer:
1 whole mile
Step-by-step explanation:
the LCD is 15. 5x3=15. what we do to the denominator we do to the top so 1x3=3 now we have 3/15.
now do that with the other fraction
3x5=15
2x5=12
12/15+3/15= 15/15= 1 whole
Answer:
b. 46°
Step-by-step explanation:
In a circle, measure of minor arc is equal to the measure of its corresponding central angle.
The answer is 1. 3/8x = 510
We know this because if we are eating 3/8 of the pizza, and we assume that the total number of calories in the pizza is x, then 3/8 of x will give us the amount of calories that we ate, which is 510. Therefore when we write this equation we get:
3/8x = 510 (3/8 of x is equal to 510)
1. Rewrite the system:
x+12y=68 (i)
x=8y-12 (ii)
2. Let's substitute the equation (ii) into the equation (i):
x+12y=68
(8y-12)+12y=68
3. Then, you have:
8y-12+12y=68
4. When you clear "y", you have:
20y-12=68
20y=68+12
20y=80
y=80/20
y=4
5. You already have the value of "y". Now, you must substitute this value into the equation (ii):
x=8y-12
x=8(4)-12
x=32-12
x=20
6. Therefore, the result is:
x=20
y=4
