x=2
Step-by-step explanation:
10x+4=2x+20
10x-2x=20-4
8x=16
x=2
Answer: x=2
2(5x+2)=2x+20. Distribute
10x+4=2x+20. Switch sides and signs
10x-2x=20-4. Combine like terms

What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares whcihh cover a closed figure's surface is its area.
We have, Radius of semicircle = 2 in
So, Area of semicircle = πr²/2
= 3.14/2 x 2/2 x 2 /2
= 1.57 x 1 x 1
= 1.57 mm²
So, the area of the semicircle is 1.57 mm².
Therefore, Radius = 1 in

Whats the distance between the points (-9,2) and (-4,2)?
A. 5
B. 13
C. 7
D. 2
Answer:
Distance between the points (-9,2) and (-4,2):
D = sqrt[(-9 - -4)^2 + (2 - 2)^2] = 5
=> Option A is correct
Answer:
B.13
Step-by-step explanation:
In order to solve the distance between two points you need the distance formula which is -> Distance = √ (x1 - x2)^2 + (y1 - y2)^2
-9 would be x1 and -4 would be x2(so the first numbers of both sets)
Then 2 would be y1 the other 2 would be y2(in this question they both have the same Ys)
You plug in the numbers to the formula.
Which would be:
Distance = √ (-9-4)^2 + (2-2 )^2
Start solving the first part and you will get this:-9-4=-13.Now that the inside is solved,you do the rest,you multiply what you got with the exponent.√(-13)^2=√169.
Then do the second part which is more simple.2-2=0 and when you multiply anything with a 0 is still 0 so when multiplied with the exponent,it stays the same.
You get left with the same answer of √169 and you just have to square root that which is 13.To check your answer,multiple 13*13 which you should get 169.:) Hopefully this was helpful and you understood everything I meant.

At a particular restaurant, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion rings and sliders is shown to have 1020 total calories and twice as many onion rings as there are sliders. Write a system of equations that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.
Step-by-step explanation:
r = onion rings amount
s = sliders amount
system of equations
2s = r
r(70) + s(200) = 1020
(for deltamath)
This question is based on the system of equations. Therefore, the system of equations 2s = r and r(70) + s(200) = 1020 are that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal.
Given:
At a particular restaurant, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion rings and sliders is shown to have 1020 total calories and twice as many onion rings as there are sliders.
According to the question,
Let the amount of onion rings be r and the amount of sliders be s.
Now, it is provided in question that, amount of sliders is twice as the onion rings. In mathematically expressed as,
⇒ 2s = r is the first system of equation.
Then, it is also give that, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion rings and sliders is shown to have 1020 total calories. This representing as,
⇒ r(70) + s(200) = 1020 is the second system of equation.
Therefore, the system of equations 2s = r and r(70) + s(200) = 1020 are that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal.

Which of the following equation have exactly one solution?

B) 58x + 52 = 78x - 78
C) -78x + 52 = -52x - 78
D) 52x + 52 = 52x -78
Answer:
A, B, C all have one solution.
Step-by-step explanation:
1) Each equation in this question has one variable (x). This means that only one solution will be there.
2) Solve for x, you can cross out option D. When you subtract 52x from both sides, you're left with 52 = -78
Which is not true

CraftWorks employed three different salespeople last year. Person 1 earned
$5500 in the first quarter, person 2 earned $7500 in the first quarter, and
person 3 earned $8000 in the first quarter. What are the maximum FUTA
deductions for the first quarter?
O A. $1229.00
O B. $806.00
O
C. $1302.00
O
D. $1209.00
Answer:
D) $1,209.00
The maximum FUTA deductions for the first quarter = $1,209.00
Step-by-step explanation:
The Federal Unemployment Tax Act (FUTA) is a tax which employers who pay their employees must pay in order to fund the state unemployment agencies. This tax is only payable on the first $1,500 to $7,000 on each emoloyees wage in a single quarter.
The FUTA current rate is 6.2%
Given that,
Employee 1 earned $5,500 in quarter 1.
Employee 2 earned $7,500 in quarter 1.
Employee 3 earned $8,000 in quarter 1.
Employee 2 and employee 3 would only be charged for their first $7,000 since they earned more than $7,000.
Therefore, the maximum FUTA deductions for the first quarter would be calculated as:
(0.062 * 5,500)+(0.062 * 7,000) + (0.062 * 7,000)
= $341 + $434 + $434
= $1,209
The maximum FUTA deductions for the first quarter = $1,209.00

Each month, Daniel budgets $1230 for fixed expenses, $780 for living expenses, and $160 for
annual expenses. His annual net income is $30,300.
Which statement best describes his monthly budget?
It shows a deficit of $355
It shows a surplus of $355.
It shows a surplus of $515.
It is balanced.
Answer:
B
Step-by-step explanation:
Monthly net income = 30300/12 = $2525
Total monthly expenses = 1230+780+160 = $2170
Surplus = 2525 - 2170 = $355
The value of the cash flow will be $355 which is surplus. Then the correct option is B.
What is cash flow?The cash balance of liquid assets coming into and going out of a business is referred to as cash flow. Money spent and money received reflect inflows and outflows, respectively.
The cash flow is the difference between outflow and inflow.
Cash flow = outflow - inflow
If the value of the cash flow is negative that means the expense is more.
If the value of the cash flow is positive that means the income is more.
Every month, Daniel spending plans $1230 for fixed costs, $780 for everyday costs, and $160 for yearly costs. His yearly overall gain is $30,300.
Then the Cash flow is calculated as,
Cash flow = ($30,300 / 12) - ($1,230 + $780 + $160)
Cash flow = $2,525 - $2,170
Cash flow = $355
The value of the cash flow will be $355 which is surplus. Then the correct option is B.

for a special 16 sided die, what is the theoretical probability for rolling a number less than 9?
Answer:
8/16
Step-by-step explanation:
there are 16 sides on the dice and there is only 8 number that are less than 9 so that makes it 8/16:)
Answer: There is a 8/16 chance of getting a number under 9.
Explanation: There is a total of 16 sides on the die. If you look at the die numbers 1, 2, 3, 4, 5, 6, 7, and, 8 are all numbers under 9. Which explains how there are 8 sides. Meaning 8 numbers are 8 sides and 16 total numbers are 16 total sides. Therefore the answer is 8/16.
44 is equal to 8 times a number minus 4. what is the number?
Answer:
6
Step-by-step explanation:
Let "a number" = x
44 = 8x - 4
Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First add 4 to both sides:
44 (+4) = 8x - 4 (+4)
44 + 4 = 8x
48 = 8x
Isolate the variable, x. Divide 8 from both sides:
(48)/8 = (8x)/8
x = 48/8
x = 6

The type of function is Quadratic.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
x 0 1 2 3 4 5
y - 1 0 - 3 - 10 - 21 - 36
As, we can see from the table ,
The first differences of the y-values are 1, 0, -3, -7, -11, -15, which are not constant.
However, the second differences are all equal to -4, which indicates that the function has a quadratic form.
