Answer:
Step-by-step explanation:
To subtract -7a^2+3a-9 from 5a^2-6-4
We have
5a^2-10--7a^2+3a-9
5a^2-10+7a^2+3a-9
Collect like terms
12a^2+3a-10-9
12a^2+3a-19
Answer:
When
solving distance problems we will use the relationship rt = d or rate (speed) times
time equals distance. For example, if a person were to travel 30 mph for 4 hours.
To find the total distance we would multiply rate times time or (30)(4) = 120.
Step-by-step explanation:
Answer: 14x+74
Step-by-step explanation:
-6x+86-32x-12+52x=14x+74
-6x+86-32x-12+52x
=-6x-32x+52x+86-12
=14x+86-12
=14x+74
Your answer is Option C) 9
Lucy used 2 1/3 kilograms of apples for her dessert.
Get the whole fraction.
3 2/3 = ((3*3) + 2) / 3 = 11/3
1 1/3 = ((3*1) + 1) / 3 = 4/3
Original weight of apples = 11/3
Remaining weight of apples = 4/3
weight of apples used = ?
Subtracting fractions:
Step 1. Make sure the denominator are the same
11/3 - 4/3
Step 2. Subtract the numerators and put the difference above the denominator
(11 - 4) / 3 = 7/3
Step 3. Simplify the fraction
7/3 = 2 1/3
