The sixth graders collected $250 of their $300 goal. The seventh graders collected $250 of thier $450 goal.
Sixth Graders:
$250 / $300
Reduce: $25 / $30 = 5/6
Seventh Graders:
$250 / $450
Reduce: $25 / $45 = 5/9
I did the problem myself and my teacher always said thatif you don't get the exact answer then round to the closest one. The answer that i got was 31,808.6, the closest one to that would be letter C.
Soz man i use the metric system
parallelogram , opposite sides are equal
so
PR = QS
and
PQ = RS
4x - 1 = 3x + 7
x = 8
PQ = 4(8) - 1 = 32 -1 = 31
Given P = 74 cm
74 - 2(31) = 12
PR = QS = 12/2 = 6
Answer
QS = 6 cm
Donald earns $23 each weekend and Mickey earns $30.
Step-by-step explanation:
Given,
Money earned by Mickey and Donald = $53
Let,
Share of Mickey = x
Share of Donald = y
According to given statement;
x+y=53 Eqn 1
x = y+7 Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 2

Putting y=23 in Eqn 2

Donald earns $23 each weekend and Mickey earns $30.
