a + a + a is the same as multiplying a by 3 so you would have 3a
b + b is the same as multiplying b by 2 so you would have 2b
Combing everything together you would have the final answer of :
3a + 2b + c

On Sunday, the high temperature was 71° F, but on Monday it was 5° F lower. What was the percent change?
Answer:
The percent change is -7%.
Step-by-step explanation:
In order to find the answer, you can use the following formula:
Percent change=(New value-Old value/Old value)*100
New value=71-5=66
Old value=71
Now, you can replace the values on the formula:
Percent change=(66-71/71)*100
Percent change=(-5/71)*100
Percent change=-0.07*100
Percent change=-7%
According to this, the answer is that the percent change is -7%.

The area of a trapezoid is 60 square inches. One of the bases is 8 inches long. The height is 6 inches long. What is the length of the second base?
Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
[tex]\frac{1}{2}[/tex] × 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches

have a great day!!!
If two ratios are similar we called the ratios to be in proportion.
The length of side x is 6 cm.
What is proportion?If two ratios are similar we called the ratios to be in proportion
We have,
Two shapes:
Consider the bigger shape width = 15 cm and length = 10 cm.
Consider the smaller shape width = 9 cm and length = x cm.
Let the ratio of bigger shape:
= Width / length
= 15/10
Let the ratio of smaller shape:
= Width / length
= 9/x
If the two figures are mathematically similar we can say that the two figures are in proportion.
We can write it as:
15/10 = 9/x
3/2 = 9/x
x = 6
Thus the length of side x is 6 cm.

Answer:
Option (2)
Step-by-step explanation:
By unitary method,
∵ 8 fluid ounces contains liquid = 237 ml
∴ 1 fluid ounce liquid = [tex]\frac{237}{8}[/tex] ml
∴ 15 fluid ounces liquid = [tex]\frac{237\times 15}{8}[/tex] ml
= 444.375 ml
Therefore, total liquid in 15 fluid ounces 444 ml.
Option (2) will be the answer.
If V is the midpoint of Line segment Q S and W is the midpoint of Line segment R S, then what is VS? 4 units 8 units 10 units 20 units
Answer:
20 units
Step-by-step explanation:
We can see that triangle QRS and triangle VWS are similar triangles.
Similar triangles are triangles in which the ratio of their corresponding sides are in the same proportion.
V is the midpoint of QS.
VS = 2a, QS = 2 * VS = 2(2a) = 4a
Since both triangles are similar triangles, hence:
[tex]\frac{VS}{QS}=\frac{VW}{QR}\\\\\frac{2a}{4a} =\frac{2a-2}{3a+6} \\\\\frac{2a-2}{3a+6} =\frac{1}{2} \\\\2(2a-2)=3a+6\\\\4a-4=3a+6\\\\a=10\ units\\\\VS=2a=2(10)=20\ units[/tex]
