Answer:
when x = 7, y = 21
Step-by-step explanation:
This is about direct variation. If y varies directly with x, then there is a constant factor of variation, k. The constant of variation can be found by ʸ⁄ₓ
k = ʸ⁄ₓ
k = ¹⁵⁄₅ = 3
Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.
y = 3x
y = 3(7)
y = 21
Answer:
x = 7.5
Step-by-step explanation:
Given
- 15 = 
( multiply both sides by - 0.5 to clear the fraction )
- 15 × - 0.5 = x
7.5 = x
Answer:
6
Step-by-step explanation:
3 3/7 * 1 3/4
~Turn into improper fractions
24/7 * 7/4
~Multiply both numerators and denominators.
168/28
~Simplify
6
Best of Luck!
24 × 60 = 1,440
1,440 × 90 = 129,600
There are 129,600 pictures in a movie that is 90 minutes long.
2 3/5 divide 6
pretend that 6 has a denominator which is 6
2 3/5 divide 6/1
make 2 3/5 into a improper fraction
multiply the whole number and denominator together
2*5=10
add 10 with the numerator
10+3=13
13/5 divide 6/1
always flip over the second fraction
13/5*1/6
13*1=13- multiply the numerators together
5*6=30 - multiply the denominators together
13/30- as a decimal=0.43333 ( the 3s continue forever )
answer:
0.433333
