A
Step-by-step explanation:
hope this helped! please let me know if im wrong
A: 7.6
Hopefully this helps!
direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
-13
300 numbers are divisible by 3
some of them include
102,105,108,111,114,117,120,123,126,
129,132,135,138,141,144,147,150,153,
156,159,162,165
i don't have an explanation just knew form a while back
hope this helped though :)
1/20
3/10 - 1/4
First, convert the fractions to a common denominator:
3/10 *2/2 = 6/20
1/4 * 5/5 = 5/20
Now put them back into the equation and solve:
6/20 - 5/20 = 1/20
Another way to do this:
Convert the fractions into decimals:
3/10 = 0.3
1/4 = 0.25
substitute back into the equation and solve:
0.3 - 0.25 = 0.05
convert back into fractions:
0.05 = 1/20
