To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.
2/10 = x/5
Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:
(5)(2) = (10)(x)
Let's multiply out these numbers to further simplify the equation.
10 = 10x
Finally, we have to divide both sides by 10, to get our variable x alone
x = 1
Therefore, 2 tenths is equal to 1 fifth.
Y=2/3x+10 - use slope intercept form
Answer:
256inches
Step-by-step explanation:
8×16 + 8×16
128+128=256
Answer:
322
Step-by-step explanation:
25 x 25 = 625
Awn. + 15 = 640
Awn. + 450 = 1090
Awn. - 768 = 322
Step-by-step explanation:
x=y³/z
(y³/z) to the power of a = y to the power of b
as b/c × 1/b = 1/c
and so we see based on the exponents that
3/b = 1/a + 1/c
