Answer:
Hannah got $200 for her mom
Step-by-step explanation:
With the numbers in this question you don't even have to worry about percentages.
You can think of it in quarters:
75% is 3 quarters of 100%
(25% + 25% + 25% + 25%)
$150 is 3 quarters of $200
($50 + $50 + $50 + $50)
Hope this helps and isn't a confusing way of explaining it! :)
Let's translate each sentence into "Math".
Pineapple = p
Orange = x
is means equal
Pineapple is 7 times as heavy as an orange: p = 7x
Pineapple weighs 870 grams more than orange. p = 870 + x
Substitute p = 7x into the second equation:
7x = 870 + x
Subtract x from both sides
6x = 870
divide by 6
x = 145
The orange weighs 145 grams.
The pineapple weights 7 times the orange = 7(145) = 1015 grams.
Answer:
C. 2(z + 3).
Step-by-step explanation:
z + (z + 6)
= z + x + 6
= 2z + 6
= 2(z + 3).
First combine like terms
3x - 7 - 2x + 5 = 6
x - 2 = 6
Get x by itself by adding 2 on both sides
x - 2 = 6
x = 8
Your answer is x = 8
