Answer:
The percent price reduction was 15.83%
Step-by-step explanation:
we know that
In this problem
$379 represent the 100%
so
using proportion
Find out what percentage represent the difference between the original price and the final price
2x + 8 > 18 2x+ 8 ≥ 18
2x > 18 -8 2x ≥ 18 - 8
2x > 10 2x ≥ 10
x > 10/2 x ≥ 10/2
x>5 x ≥ 5
The answer that combines both inequality is x ≥ 5
Add like terms
-4x+x=-3x
6-2=4
So the simplified term is 4-3x
Answer:
C. 114
Step-by-step explanation:
bikes have 2 wheels
skateboards have 4 wheels
incline skates have 8 wheels in total
7*2 = 14
9*4 = 36

if you add all of these up you get 114 wheels in total. 8*8 was from 24-7-9 = 8
Answer:
As a column vector 3a +b = (9,10)
Step-by-step explanation:
A =
(2
4)
b =
(3
-2)
3a = 3*2 = 6
3*4= 12
3a + b = 6. + 3
12. +(-2)
3a +b = 9
10
As a column vector 3a +b = (9,10)
