Answer:
E = 58
F = 32
G = 90
Step-by-step explanation:
3x + 31 + 5x -13 + 90 = 180
3x + 31 + 5x -13 = 90
8x = 90 - 31 + 13
8x = 72
x = 72 / 8
x = 9
E = 3(9) + 31 = 27+31 = 58
F = 5(9)-13 = 45 - 13 = 32
G = 90

Answers
Answer:
50 pencils
Step-by-step explanation:
2.19/12 = .18
3.99/40 = .09975
4.75/50 = .095
10/100 = .10
Although with mark-up to the hundredths place, there wouldn't be a logical difference is stores...
Answer:
50 for $4.75
Step-by-step explanation:
First step is to determine the unit cost of each pencil:
price of pack / number of units = cost per pencil
1. $2.19 / 12 = $0.1825
2. $3.99 / 40 = $0.09975
3. $4.75/ 50 = $0.095
4. $10 / 100 = $0.10
The correct answer is $4.75 for 50 pencils because it is the lowest per unit cost.

We see the two curved parts on the figure, this means those angles are congruent. That means x is congruent to that other angle.
We see the box type angle on the bottom. That is a right angle. It represents 90 degrees.
Pentagon's interior angles add up to be 540.
So, add them up together, equal to 540, and solve for x.
540 = 70 + x + x + 110 + 90.
540 = 260 + 2x
270 = 2x
135 = x.
The angle x is equal to 135.

Explanations:
6) We apply the square root to both sides to undo the squaring operation.7) The photo without the frame is 8 by 10 since we add on two copies of x to jump from 8 to 8+2x. Similarly, we go from 10 to 10+2x.8) The x represents the thickness of the frame. The 100 is the total area (picture + frame). The expression on the right hand side is also the total area.9) Apply the zero product property to set each factor equal to zero. You'll find that x+5 = 0 leads to x = -5. Also, 2x-3 = 0 becomes 2x = 3 and solves ultimately to x = 3/210) Refer to problem 9

Together Jason and Judy have read 24 mystery novels. Judy has read less than three times as many as Jason. How many mystery novels have each of them read.
Answers
Omitted / Incomplete Question : Judy has read 4 Less than three times as many as Jason
Answer:Jason has read 7 mystery novels and Judy has read 17 mystery novels
Step-by-step explanation:
Total number of mystery books read by Jason and Judy =24
Let Number of mystery books read by Jason=x
and Number of mystery books read by Judy= 3x-4
So that the total number of book read by both of them will be expressed as
x +(3x-4) =24
x +3x-4 =24
4x=24+4
4x=28
x=28/4=7
There fore Jason has read 7 mystery novels
and Judy = 3x-4 = 3 X 7- 4 =21-4=17mystery novels

tamika has $55 in her savings account. She plans on depostiting $5 per week into her account. Write and solve an inqequality to find out how many weeks she must save to have more than $100 in her account. Then interpet the solution
Answers
Answer:
x>9
Step-by-step explanation:
Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.
The question also asks to solve the inequality:
55+5x>1005x>100-55 (Subtract 55 from each side)5x>45x>9 (Divide each side by 5)This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.
