The number that is halfway between 3/5 and 7/10 is 13/20.
70 cups>35 pints>17.5 quarts of water in a week
10 cups × 7 days (a week)= 70 cups
2 cups = 1 pints
70 cups ÷ 2= 35 pints
2 pints = 1 quart
35 pints ÷2 = 17.5 quarts
Hope this helps!
H^2=x^2+y^2 and xy=168 so y=168/x
625=x^2+28224/x^2
625=(x^4+28224)/x^2
x^4-625x^2+28224=0
I'll use the quadratic because this is a big number :P
x^2=(625±√(277729))/2
x^2=(625±527)/2
x^2=49
x=7
168/7=24
So the dimensions of the painting is 7 inches by 24 inches.
Answer:
a=-1.2
Step-by-step explanation:
5x-10=3x+a=12
let's first find x:
5x-10=12
add 10 to both sides:
5x=22
divide both sides by 5:
x=4.4
now that we know what x is, we can plug it back into the equation to find a:
3*4.4+a=12
first, simplify both sides:
13.2+a=12
then, subtract 13.2 from both sides:
and our answer is: a=-1.2
