The sum of twice a number and 13 is 47. Find the number.
Answer: 17
Step-by-step explanation:
In this problem, the phrase "a number" can be interpreted as a variable. In this case, let the variable be "x."
Thus, "twice a number" = "2x"
"and 13" = "+ 13"
"is 47" = "= 47"
Thus, the problem is simply 2x + 13 = 47.
Then, simply subtract 13 from both sides to get 2x = 34.
Then, simply divide both sides by 2 to get x = 17.
Because "the number" is "x," the number is 17.

You can subtract a negative number from a positive number or add a positive number to a negative number
Example:
4 - (7) = -3
Or
-8 + 9 = 1
Whatever you are adding has to be greater than the number you are adding on too
Example:
-3 + 5 = 2
Notice how the five is greater than 3
Whatever you are subtracting has to be Greater than the number you are subtracting from.
Example:
5 - 8 = -3
Notice how the eight is greater than five.
The situation changed when adding or subtracting with negative numbers. Every situation is different.

what is the additive inverse of [tex]\frac{2}{3}[/tex]
A. 3/2
B. 0
C. -2/3
D. -3/2
show al your work please due very soon
Answer:
your answer is C. -2/3
Step-by-step explanation:
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the additive inverse (opposite number) of a positive number is negative, and the additive inverse of a negative number is positive. Zero is the additive inverse of itself. In this case, -2/3 is the additive inverse of 2/3.

Louise owns a hot dog stand. The amount of money she collects from selling hot dogs each day can be found by using the equation y=3.5x What does 3.5 from the equation represent in the situation?
Answer:
3.5 represents the cost of each hotdog ($3.50).
Step-by-step explanation:
In y = 3.5x, the x represents the number of hotdogs and the y represents the total amount you have to pay for those hotdogs. The 3.5 represents the cost of each hotdog.

The largest amount of money in your bank account was $143.
Write an inequality for the possible amount of money, m, in your bank account.
The smallest species of frog is 7.7 millimeters long.
Write an inequality for the height, h, of all the other frog species.
Answer:
a) [tex]m\leq 143[/tex]
b) [tex]h>7.7[/tex]
Step-by-step explanation:
1. Part aPart a says the largest amount was $143
Largest = $143
It doesn't say it can't equal $143
[tex]m\leq 143[/tex]
2. Part bPart b says the smallest was 7.7 mm
Smallest = 7.7 mm
It says for all other frog species, so not including the smallest

In the figure shown, line AB is parallel to line CD.
Part A: What is the measure of angle x? Show your work. (5 points)
Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
Answer:
Part A
x is 46°
Part B
Alternate angles are angles that are in relatively opposite locations relative to a transversal
Step-by-step explanation:
Part A
∠DRP = 110° (Given)
∠QPA = 64° (Given)
∠QPR =
Given that AB is parallel to CD, we have;
∠DRP is congruent to ∠APR (Alternate angles to a transversal RP of parallel lines AB and CD)
Therefore, ∠APR = 115°
∠APR = ∠QPA + ∠QPR (Angle addition postulate)
∴ 115° = 64° + ∠QPR
∠QPR = 110° - 64° = 46°
x = 46°
Part B.
Given that AB is parallel to CD, the lines common (that intersects) both lines are the transversal lines
The angles formed between the parallel lines and the transversal lines have special relationships based on their position with respect to each other
In the question, the angle 110° given between CD and the transversal RP, is found to at an alternate position to the angle ∠APR between the same transversal RP and AB and given that alternate angles are always equal, angle ∠APR is therefore also equal to 110°.
The table shows values for Variable A and Variable B.
Use the data from the table to create a scatter plot.

A) what is the simplified product of seven-fourths divided by eight-fifths as an improper fraction
B) what is this number as a mixed number
Answer:
A)First were going to put our numbers in perspective.
[tex]\frac{7}{4}[/tex] ÷ [tex]\frac{8}{5}[/tex]
But to find the improper fraction, we have to cross multiply these numbers.
[tex]\frac{7}{4}[/tex] × [tex]\frac{8}{5}[/tex]
7 x 5 = 35.
4 x 8 = 32.
Now we have our improper fraction is [tex]\frac{35}{32}[/tex]
B)To turn our improper fraction into a mixed number, we will use division.
We know that the 32 can only go into 35 one time. We also know that the bottom number always stays the same. So our equation will look somewhat like this.
[tex]1\frac{?}{32}[/tex]
Now to fine the top number we will have to subtract 35 from 32 because we already know that 32 can go into 35 one time, so 35 - 32 = 3. So are mixed number will look like this.
[tex]1\frac{3}{32}[/tex]
This is our answer!
Answer:
7/4 ÷ 8/5
A. First, we need to do the reciprocal of 8/5.
7/4 x 5/8 = 35/32
B. Now, we need to convert it into a mixed number. Divide 35 by 32. 32 goes into 35 one time. 35 - 32 = 3, so remainder 3. We use 1 as the whole number since 32 goes into 35 one time. We use the remainder 3 as the numerator, and 32 as the denominator.

Which event would be closest to having a probability
of occurring of 0.8?
a) choosing a vowel from the set {a, e, i, o, u}
b) choosing an odd number from the set {2,4,6,8,9}
c) choosing a consonant from the set {b, c, d, e, f}
d) choosing an even number from the set {1,3,5,7,9}
Plz hurry. AND NO LINKS PLZ
Answer: c) choosing a consonant from the set {b, c, d, e, f}
Step-by-step explanation:
Since all of the choice sets have 5 values each, a 0.8 chance = 80% = [tex]\frac{4}{5}[/tex].
So find the set with 4 values that meet the criteria.
A: 5/5 = 1 = 100%
B: 1/5 = 0.2 = 20%
C: 4/5 = 0.8 = 80%
D: 0/5 = 0 = 0%
