35r+10+20p
you would multiply by 5 to all the numbers in the parantheses
To multiply two fractions:
-- Multiply their numerators; the product is the numerator of the new fraction.
9 x 7 = 63 ; the new fraction is (63) / (something)
-- Multiply their denominators; the product is the denominator of the new fraction.
1 x 10 = 10 ; the new fraction is <em>63/10</em> .
The product of the two original fractions is 63/10 , or <em>6.3</em> .
Answer:
9.8
Step-by-step explanation:
The formula for the area of a triangle is a=bh/2, where a is area, b, is the base, and h is the height. If we substitute the values in the question in the equation, we get:
a=(6.5*3)/2
a=19.5/2
a=9.75
a≈9.8

Answer:
Step-by-step explanation:
Consecutive interior angles between parallel lines are supplementary.
Let's start with x.
(8x +40)° +(6x)° = 180°
14x +40 = 180 . . . . . . . . . divide by °, collect terms
14x = 140 . . . . . . . . . subtract 40
x = 10 . . . . . . . . divide by 14
__
We can use the same approach for y:
(7y)° +(3y -10)° = 180°
10y = 190 . . . . . . . . . . . divide by °, add 10, collect terms
y = 19 . . . . . . . . . . . divide by 10
