Answer:
(5, -2)
Step-by-step explanation:
x - 7 = -2x + 8
add 2x to both sides
x - 7 + 2x = -2x + 8 + 2x
3x - 7 = 8
Add 7 to both sides
3x - 7 + 7 = 8 + 7
3x = 15
3x = 15
x = 5
y = 5 - 7
y = -2
Solution (5, -2)
Answer:
$13.75 should be your answer
Step-by-step explanation:
Note that 45 nickles = 45 x 5 = 225 cents
Note that 10 quarters = 10 x 25 = 250 cents
Note that 18 half-dollars = 18 x 50 = 900 cents.
225 cents = $2.25
250 cents = $2.50
900 cents = $9
Add
2.25 + 2.50 + 9 = 13.75
~
7+z / 2
z = 10
replace the value of z
7 +10 /2
use order of operations ( division comes before addition)
7+5 = 12
