Find the product of 51 and -2.5.
Use the distributive property to rewrite and solve.
The first step is done for you.
51(-2.0) + 51(-0.5)
What is the next step in using the distributive property to solve this equation?
A) -102 + 25.5
B) 102 + (-25.5)
C) -102 + (-25.5)
D) -102 + (-25)
Answer:
A. -102 + 25.5.
Step-by-step explanation:
After multiplying 51 by -2.0, you will get -102. When multiplying 51 by -0.5, you get 25.5. A is the next step in this equation. (Optional answer: read this when this is also in your quiz. -102 + 25.5 = 127.5).

Meghan ran nine twelfths of a mile and skipped eight twelfths of a mile around a track. How far around the track did Megan go in total? Use the benchmark fraction one half , 1, and 0 to help you estimate each answer before you solve. a one twelve mile b one and five twelfths miles c one and seven twelfths miles d twelve seventeenths mile
Answer: megan went a total distance of 1 5/12 miles or 17/12 (use which ever you need)
Step-by-step explanation:
Here, we want to calculate the total distance worked around the track
We are told that she ran 9/12 and skipped 8/12
The total distance around the track will be the sum of these two
Mathematically, that will be;
9/12 + 8/12= 17/12 but if wanted in mixed fraction [tex]1\frac{5}{12}[/tex]

5(x−3 3/4)=7 1/2
the answer is 10x
Solve for
x
by simplifying both sides of the equation, then isolating the variable.
x
=
10
Answer:
x = 5[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
5(x - 3[tex]\frac{3}{4}[/tex] ) = 7[tex]\frac{1}{2}[/tex]
Use distributive property
5x - 18[tex]\frac{3}{4}[/tex] = 7[tex]\frac{1}{2}[/tex]
Add 18[tex]\frac{3}{4}[/tex] to both sides
5x = 26[tex]\frac{1}{4}[/tex]
Divide both sides by 5
x = 5[tex]\frac{1}{4}[/tex]

What is the measure of the exterior angle? Show all steps.
Answer:
108 degrees
Step-by-step explanation:
The thereom for this is the interior angles (a+10) and 44 degrees add up equaling to 2a. This works for any triangle like this. So, a+10+44=2a, and we solve for a to 54 for a. Then we insert a as 54 for 2a to get 54*2=108 degrees.
If the population of an ant hill doubles every 10 days and there are currently 100 ants living in the ant hill, what will the ant hill population be in 20 days?
Answer:
400
Step-by-step explanation:
The current number is 100, it doubles every ten days, and you're asking what the size will be in twenty days.
Beginning:
100 ants (ten days pass)
100 x 2 = 200
Middle:
10 of the 20 days have passed
Your new number is 200 ants
End:
200 ants (ten days pass)
Since every ten days the size doubles: 200 x 2 = 400
400 ants after 20 days

Evaluate 1/5y + 4/15 when y = 1/3
Answer:
= [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
First, plug-in y for 1/3 since y = 1/3
[tex]\frac{1}{5} (\frac{1}{3} ) + \frac{4}{15}[/tex]
then multiply first according to the order of operations, then do the addition:
[tex]\frac{1}{5} * \frac{1}{3} =\frac{1}{15}[/tex]
[tex]\frac{1}{15} + \frac{4}{15}[/tex] = [tex]\frac{5}{15}[/tex]
then reduce:
[tex]\frac{5}{15} \to \frac{2}{3}[/tex]

On the first visit to the veterinarian's office, Cora's kitten weighed 550 grams. On the second visit, the kitten had gained 350 grams. On the third visit, the kitten had gained another 300 grams.
What is the percent increase since the first visit in the kitten’s weight rounded to the nearest percent?
PLSS HELPP
Answer:
On first visit, weight =550 g
Weight gained on second visit= 350 g
Weight gained on third visit= 300 g
Present weight=550+350+300= 1200
Weight gained=1200-550=650
Percentage of weight increased
-------->650/550 × 100 = 118.18\%
So the kitten gained 118% weigh
