Answer:
-11/70
Step-by-step explanation:
Rearrange it first, we got:
-2/5 x -3/7 -3/5 x 3/7 -1/14
Then:
=2/5 x3/7 -3/5x3/7 -1/14
Next:
(2/5-3/5) x3/7 -1/14
=(-1/5)x3/7 -1/14
=(-3/35)- 1/14
=(-6/70)-5/70
=-11/70
Answer:
6
Step-by-step explanation:
7x + 3(-x + 6) = 42
use distributive property
7x + -3x + 18 = 42
positive + negative = negative
7x - 3x + 18 = 42
combine like terms
4x + 18 = 42
subtract 18 from both sides
4x + 18 - 18 = 42 - 18
18 is canceled out on the left side
4x + 0 = 24
4x = 24
divide both sides by 4
4x ÷ 4 = 24 ÷ 4
1x = 6
x = 6
Answer:
190
Step-by-step explanation:
1/8= 5 ft
19/4 = 38/8
38/8 = 38*5 = 190 feet
5 pizza / 6 student = 'Z' pizza / 1 student
Cross-multiply the proportion:
5 pizza-student = 6 Z pizza-student
Divide each side of the equation by 6 pizza-student :
5/6 = Z
Each student gets 5/6 of 1 pizza.
It's not so complicated. Cut each pizza into 6 slices,
and each student gets 5 slices.
That's the same as (83 and 1/3) percent of a pizza.
