Answer/Step-by-step explanation:
5. 21x + 4 = 22x - 2 (corresponding angles)
Collect like terms
21x - 22x = -4 - 2
-x = -6
divide both sides by -1
x = 6
6. (x + 72) + (x + 132) = 180 (linear pair)
x + 72 + x + 132 = 180
Add like terms
2x + 204 = 180
2x = 180 - 204
2x = -24
x = -12
7. 90 = 22x + 2 (vertical angles)
90 - 2 = 22x
88 = 22x
Divide both sides by 22
4 = x
x = 4
8. 12x + 10 = 13x + 3 (vertical angles)
Collect like terms
12x - 13x = -10 + 3
-x = -7
Divide both sides by -1
x = 7
9. 17x = 16x + 5 (alternate exterior angles)
17x - 16x = 5
x = 5
✔️17x
Plug in the value of x
17(5) = 85°
10. 21x - 6 = 20x (corresponding angles)
Add like terms
21x - 20x = 6
x = 6
✔️20x
20(6) = 120°
If the ride cost $9 then the miles will be 3 miles.
Step-by-step explanation:
In this question we are given:
Cost of one cab ride R = $3
Additional Cost per mile M = $2
So, Total cost of Cab Ride = $3 + $2M
If cost of cab ride is $9 then we need to find the miles
$3 + $2M = $9
Solving
$2M = $9 - $3
$2M = $6
=> M = $6/$2
M = 3 miles
So, if the ride cost $9 then the miles will be 3 miles.

Answer:
B.$8.98
Step-by-step explanation:
We need to determine the cost per ounce. We divide the cost by the number of ounces
3.59/16 =.224375 per ounce
Take the price per ounce and multiply by the number of ounces to determine the price of the 40 ounce jar
.224375 * 40 =8.975
Rounding to the nearest cent
8.98 for a 40 ounce jar
X= purchase price
Multiply purchase price by sales tax % to equal the amount of sales tax.
(8.75% * x)= $15.75
convert % to decimal (8.75% ÷ 100)
0.0875x= 15.75
divide both sides by 0.0875
x= $180.00 purchase price
ANSWER: The purchase price is $180.00 (to nearest cent).
Hope this helps! :)
