Answer:
$50 - d = $22.50
Step-by-step explanation:
Since she's receiving a change, it means that d is smaller than $50, therefore, it will be deducted from it to give the change.
Answer:
x=-11/6, y=7/6. (-11/6, 7/6).
Step-by-step explanation:
-2x+2y=6
4x+2y=-5
-----------------
2(-2x+2y)=2(6)
4x+2y=-5
----------------------
-4x+4y=12
4x+2y=-5
----------------
6y=7
y=7/6
4x+2(7/6)=-5
4x+14/6=-5
4x=-5-14/6
4x=-30/6-14/6
4x=-44/6
x=(-44/6)/4
x=(-44/6)(1/4)
x=-44/24
simplify
x=-11/6
Answer:
it is 56 I think I haven't done this in a while
1,425 = 114%
so
1,425 = 114% • x
1,425 × 100 ÷ 114 = x
x = 1250
hope this helps!
