Step-by-step explanation:
A. 7(s + c)
= 7s + 7c
B. The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. The total amount that Julio spent at the bookstore would be calculated as:
= 7s + 7c
= 7($5.99) + 7($6.49)
= $41.93 + $45.43
= $87.36
We then add tax which will then be:
= $87.36 + (6% × $87.36)
= $87.36 + (0.06 × $87.36)
= $87.36 + $5.24
= $92.60

Decrease 151.1 by 84%
Answer:
84% of 151.1 being reduced from 151.1 is what we need to find.
Thus we shld find 84% of 151.1
12,692.4÷100
126.924
Now subtracting 126.924 from 151.1
151.1 - 126.924
24.176
Answer:
24.176
Step-by-step explanation:
Let's find 84% first of 151.1 before we decrease it.
Since we have 84%, we can turn into a decimal and use it for our sum.
84% = 0.84
We multiply 151.1 by 0.84 in order to find the amount (strange right? I thought it was divide).
151.1 × 0.84 = 126.924
Now that we have 84% of 151.1, let's decrease it. We need to take them both away from each other, biggest number first!
151.1 - 126.924 = 24.176
And that is the final answer!
Which answer has the smallest value?
1) |-100|
2) the opposite of 50
3) 0
4) the opposite of 25
5) -5
Answer:
The smallest value is 2) the opposite of 50 because it is farthest left of the zero (this makes it the smallest)
Step-by-step explanation:
1) = 100
2) = -50
3) = 0
4) = -25
5) = -5

Answer:
m∠1 = 130°
m∠2 = 158°
Step-by-step explanation:
For the given figure, we have;
The measure of angle m∠1 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;
m∠1 = 99° + 31° = 130°
m∠1 = 130°
Similarly, the measure of angle m∠2 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;
m∠2 = 28° + m∠1 = 28° + 130° = 158°
m∠2 = 158°.

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Step 1: Set Up
Let's let our number be set by variable n.
We add 7 to it: n + 7
We then double that entire expression: 2(n + 7)
That expression is equal to 82.8: 2(n + 7) = 82.8
Step 2: Solve for n
[Division Property of Equality] Divide 2 on both sides: n + 7 = 41.4[Subtraction Property of Equality] Subtract 7 on both sides: n = 34.4∴ Caroline's original number is 34.4.

What conclusion can you make from the information below?
Three boys (Dmitri, Ken, and Adam) have three different favorite colors (red,green, and blue)
• Dmitri does not like red
• Adam does not like red.
A. Dmitri's favorite color is blue.
B. No one likes green
C. Ken's, favorite color is red
D. Ken's favorite color is not red.
========================================================
Explanation:
We're told that Dmitri and Adam do not like red. So that must mean that Ken likes red. This immediately leads to choice C as the answer. This is assuming that each boy picks one of the three colors (and no colors can be repeated).
----------------
Extra info:
Choice A is false because we're not sure if Dmitri likes blue or green. We don't have enough info. Choice B is false because someone has to pick green. There are three boys and three colors. Again I'm assuming each person picks one color and the colors aren't repeated.Choice D is false because it contradicts choice C.2 times the sum of 5 and y?

Answer:
25% or 1/4
Step-by-step explanation:
The probability of all correct is [tex]\frac{1}{4}[/tex] or 25%.
Given that,
There are 3 questions given i,e a =3. Each question had four choices i.e b = 4.We need to find the probability of all three correct.According to the situation, calculation of given data are as follows,
Probability of all correct = [tex]\frac{a}{(a \times b )}[/tex]
By putting the value, we get,
Probability = [tex]\frac{3}{(3 \times 4) }[/tex]
= [tex]\frac{3}{12}[/tex]
By simplifying the fraction, we get,
Probability = [tex]\frac{1}{4}[/tex] or 0.25 or 25%.

Make x the subject of m= n + x/p
Answer:
x = m × p - n
Step-by-step explanation:
[tex]m = n + \frac{x}{p} [/tex]
We can first multiply both sides by p.
[tex]m \times p = n + x[/tex]
And now we only have n left with x, so we subtract n on both sides.
[tex]m \times p - n = x \\or \\ x = m \times p - n[/tex]
