Answers
Answer:
(Choice A) A 10
(Choice C) C 20
Step-by-step explanation:
Fraction 1: 2/5
Fraction 2: 3/10
rewrite them so that they have a common denominator (and whole number numerators
For both fractions to have a common denominator, find the lowest common multiple of both denominators
5 = 5, 10, 15, 20, 25, 30, 35, 40

A mother bear and her cub catch fish from a river . The mother bear catch 10 fish the mother bear catch 5 times as many
Answers
Answer:
This doesn't make sense.
Step-by-step explanation:
If the question was "A mother bear and her cub catch fish from a river. The cub catches 10 fish and the mother bear catches 5 times as many as the cub. How many fish did the cub catch?" then the answer would be, The mother bear caught 50 fish.
This is because if the cub caught 10, and the mother caught 5 times that amount, the mother caught 5 x 10 fish. 5 x 10 = 50.

Answers
Answer:
$131.85
Step-by-step explanation:
First, we need to find the net price (after discount and tax) It's a 15% discount, so just find 85% (100-15=85) of the original price. You'll get $373.15.
For tax, multiply by 1.06, since it's a 6% tax (1+.06). You'll get $395.539.
You're paying over 3 months time, so to find payment each month just divide by 3.
395.539/3 = 131.8463333
Round to 131.85
Your answer is $131.85 dollars per month

200 tickets were sold in a school’s annual musical performance. Students' tickets cost $2.50 each and parents tickets cost $3.50 each. The total amount collected was $537. How many tickets were sold for parents?
Answers
Answer:
Step-by-step explanation:
number of students ticket sold = x
number of parent tickets sold = y
If a total of 96 tickets were sold
x+ y =96 ---- eq 1
If a total of 96 tickets were sold for $306.25
2.50x + 3.75y=306.25 ---- eq 2
x+ y =96
y=96-x
substitute value of y in equation 2
2.50x + 3.75 (96-x)=306.25
2.50x + 360 -3.75x =306.25
- 1.25 x = -53.75
x = 43
therefore the answer would be y=96-x=96-43=53

Answers

$24.99 x 4 = $99.96
$99.96 + $125.57 = $225.53
$225.53 + $15.93 = $241.46
$241.46 - 6% = $226.97
if 1/2p=2 1/2q, find q:p
its 2 and a half not 21/2
Answers
Answer:
1/5 = q/p, or q:p
Step-by-step explanation:
You might want to rewrite 1/2p=2 1/2q as (1/2)p = (2 1/2)q.
To remove the fractions, multiply both sides by 2:
p = 2(2 1/2)q becomes p = 5q.
Dividing both sides by 5 yields p/5 = q.
Dividing both sides by p yields 1/5 = q/p, or q:p
