Answer:
This is the interval from -9 to 16. Exclude -9 but include 16.
=====================================================
Work Shown:
The idea is to multiply all sides by 5, then add 1 to all sides
This converts to the interval notation
note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
Answer:
Levi is 53 yrs now
Step-by-step explanation:
sum = 76yrs
Levi = 3x -8
Monique = x - 8
8yrs ago
sum= 76 - 8 - 8( the two 8s are from each of the two brothers).
= 60yrs
Levi=3x
Monique=x
3x + x = 60
4x = 60
x = 15yrs
Levi = 3x
= 15 x 3
= 45 yrs(8yrs ago)
now = 45 + 8
= 53yrs now
Monique = x
= 15
now = 15 + 8
23yrs now
Q1
the clothes are on 45% discount, wich mean they become 55% of their original price.
30× 55% =16.5
64×55%=35.2
the new salary is 103% of the original
10×103% = 10.3
11600×103% = 11,948
Q2:
1+0.24= 1.24
1- 0.27= 0.73
86×140%= 120.4
440×119%= 523.6
82×90% = 73.8
480× 73%= 350.4
Answer:
