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:
because it is a triangle we square the lenght and equate to the other side,and square all the other side
X²=20²+10²
X=√20²+10²
=22.36m
Answer:
the amount spend on the ribbon is $51
Step-by-step explanation:
The computation of the amount spend on the ribbon is shown below:
= Total ribbons bought × ribbon cost per meter
= 17 × $3
= $51
Hence, the amount spend on the ribbon is $51
Answer:
60
Step-by-step explanation:
<H + <T = 180
2x+ 60 + x + 30 = 180
3x + 90 = 180
3x = 90
x = 30
<T = x + 30 = 30 + 30 = 60
Answer
<T = 60
For example, lets take

We need to first factor the numerator and denominator to find the common numbers which we can simplify it by.

If we divide by 5 x 5 on both the numerator and denominator because both of them have it in common, we will get the simplest form.
