Answer:
z = 4
Step-by-step explanation:
12z - 18 = 30
add 18 to both sides:
12z = 48
divide by 12:
z = 4
Let the price in storeB=x
5/6x=150.6
x=180.72
180.72-150.6=$30.12
you save $30.12
Answer:
x=55
Step-by-step explanation:
The exterior angles of a polygon add to 360.
x+x+x+x+x+x+30 = 360
Combine like terms
6x+30 = 360
Subtract 30 from each side
6x+30-30 = 360-30
6x = 330
Divide by 6
6x/6 =330/6
x =55
Answer:
- 4x + 36
Step-by-step explanation:
(
- 6)² = (
- 6)(
- 6)
Each term in the second factor is multiplied by each term in the firs t factor, that is
(
- 6) - 6(
- 6)
Distribute both parenthesis
=
- 2x - 2x + 36 ← collect like terms
=
- 4x + 36
cosine ( CAH) = Adjacent/ hypothenus
cos9 = x/ 2
let x represent the horizontal distance
2 cos 9 = x
x = 2 (0.98768834)
x = 1.975
x = 1.97
therefore the horizontal dstance jade covers is 1.97km
