J Is the answer, (x+6)(x-3) is the equivalent
He is overestimating because 2.25 * 6 = 13.5, which is less than 11.5
<span>The answer is 6:18, 8:24, 12:36</span>
Answer: 14.60
Step-by-step explanation:
we have
14 3/5
This is a mixed number
we know that
A mixed number is a combination of a whole number and a fraction.
So
14 3/5 is equal to
14+3/5
where
14 is the whole number
3/5 is the fraction
3/5 = 0.60
14 + 3/5 = 14 + 0.60
therefore
= 14.60
the answer is
14.60
Answer:
a = 18
Step-by-step explanation:
2(a-7)=a+4
Distribute 2 into left side: 2a -14 = a + 4
subtract a from both sides 2a-a-14 = a+4-a
Simplify: a - 14 = 4
Add 14 to both sides: a - 14 + 14 = 4 +14
Simplify: a = 18
If wanted, plug a into original to double check work:
plug in: 2 (18-7) = 18+4
do parenthesis first: 2 (11) = 18+4
do multiplication : 22 = 18+4
additions: 22 =22
a = 18 is correct.
