Answer:
7. x = 5
8. x = 2, y = 6
9. x = 21, y = 39
Step-by-step explanation:
For a parallelogram, the lengths across intersection are equal.
7. For a parallelogram, the lengths across intersection are equal.
So that,
3x = 4x - 5
4x - 3x = 5
x = 5
8. For a parallelogram, the lengths across intersection are equal.
So that,
2x = 4
x = 
x = 2
and
y - 1 = 2y -7
7 - 1 = 2y - y
y = 6
x = 2, y = 6
9. For a parallelogram, opposite angles have equal value.
Thus,
3x = (4x - 21)
3x = 4x - 21
x = 21
and
3y = (y + 78)
3y = y + 78
3y - y = 78
2y = 78
y = 
= 39
y = 39
x = 21, y = 39
Answer:
$720
Step-by-step explanation:
$1,200 divided by 2 (600) equals how many vanilla cupcakes there were.
40 people times 24 cupcakes each person (960) equals how many total cupcakes there were.
The total amount of cupcakes minus the amount of vanilla cupcakes equals the amount of chocolate cupcakes (960-600=360).
360 chocolate cupcakes times the amount each cupcake was sold for equals the amount of money raised from the chocolate cupcakes (360x2=720).
40 hrs at 8 bucks, 40*8 or 320, now, is 2 workers, so 320+320 or 640
so... how much is 640 from 2000 in percentage? well, if we take 2000 as the 100%, then

solve for "x"
8/10 is close to 1(8/10 = 0.8 and 5 and up you round up)
4/9 is close to 0 (4/9 = 0.44 and 4 and down you round down!)
