Mixed Number Form: 6 11/45
Exact Form: 281/45
Answer:
- 9x + 12
Step-by-step explanation:
Given
(- 7x + 4) - (2x - 8) ← distribute parenthesis by 1 and - 1
= - 7x + 4 - 2x + 8 ← collect like terms
= - 9x + 12
Answer:
2 x 7 x 3²
Step-by-step explanation:
When finding primes, you use the method I attatched as a picture. Start with the large number at the top, slowly dividing it by factors of it.
The picture shows that the primes 126 is a product of is:
2, 7, 3, 3
Or:
2 x 7 x 3 x 3
This can be simplified into:
2 x 7 x 3²
Hope this helps!
Answer:
length= 100 width=70
Step-by-step explanation:
The perimeter of a rectangular field is 340 yds.
The length is 30 yds longer than the width.
2(l + w) = 340
l + w = 170
w + 30 + w = 170
2w = 140
w = 70
Hence the dimensions:
Length: 100 yds.
Width: 70 yds.
Step-by-step explanation:
"Of" means multiplication, and percent means out of 100.
25/100 × 150 = 700/100 × n
75/2 = 7n
n = 75/14
n ≈ 5.357
