Set u a ratio of height over shadow:
Lance = 5 feet tall / 8 foot shadow
Tree = X feet tall / 32 foot shadow.
Set the ratios equal to each other and solve for X:
5/8 = x/32
Cross multiply:
8x = 160
Divide both sides by 8:
x = 160/8
x = 20
The tree is 20 feet tall.
When a equation uses 'of', it usually means multiplication and 'is' means equal.
4/5 x P= 48
However, you want to figure out what P is before answering 3/5.
(4/5)(P)=48 Divide 4/5 by both side
P=60
Then you want to find what 3/5 of P is. Since we know what P is, we can figure out the answer.
X= 3/5 (60)
x= 36 so the answer is D.
There are no common factors between the two terms
13
x
and
10
- see explanation below.
Explanation:
First, we can try factoring the constants in each term:
13 is a prime number and therefore can only be factored to 1 and 13.
10 can be factored as (1 x 10) or (2 x 5).
Because there are no common factors other than
1
the constants cannot be factored.
And, because there is no
x
in the second term (10), we cannot factor an
x
out of the two terms.
Therefore this expression cannot be factored.
