Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes
Multiply hours per week by hourly pay rate:
20 x $15.75 = $315.00 per week
Multiply by 2 weeks:
$315 x 2 = $630
After 2 weeks paycheck is $630
Answer:
630
Step-by-step explanation:
15.75 x 20 = 315
315 is how much Angel makes in one week
315 x 2 = 630
630 is how much he will make in two weeks
The 2 signifies how many weeks have been worked

Step-by-step explanation:
8x-27=6x+7
8x=6x+34

8(17)-27= 109
Answer: 109
Step-by-step explanation:
i'm not entirely sure of this answer as its been a while since ive done problems like this, however, i think the steps to solve are setting (8x-27) equal to (6x+7). Once you do that, you can solve for x. Substitute x into angle DBC to find the answer.

Answer:
Step-by-step explanation:
i.
(10y+x) - (10x+y) = 63 ---> This subtracts the original from the number with the reversed digits, and makes it equal to 63, so the number increases by 63
y - x = 7 ---> We have to prove this is true, so put it into the original equation
y = 7 + x ---> manipulate the above equation, and substitute it into the original equation
[10 (7 + x) + x] - [10x + (7 + x)] = 63
(70 + 11x) - (11x + 7) = 63
63 = 63 ---> Solve the equation, and because it comes out to be true, you proved that y - x = 7
ii. a.
(10x + y) + (10y + x) = 99 ---> The sum of the original and reversed numbers
x + y = 9
y = 9 - x ---> substitute this into the original equation
[10x + (9 - x)] + [10 (9 - x) + x] = 99
(9x + 9) + (90 - 9x) = 99
99 = 99

Use the Pythagorean theorem to solve for the diagonal distance
Diagonal = sqrt(50^2 + 150^2)
Diagonal distance = sqrt(25,000)
Diagonal distance = 158.11 feet
Round to 158 feet.
If the stayed on the sidewalk they would walk 50 + 150 = 200 feet.
The distance they saved = 200-158 = 42 feet
Answer: 42 feet.

the hcf of 90 and x is 18. the lcm of 90 and x is 540. find the value of x.
The value of x is 108.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that the HCF of 90 and x is 18.
And the LCM of 90 and x is 540.
We have to determine the value of x.
Since the product of two numbers equals the product of their HCF and LCM.
So 90 × x= HCF × LCM
Substitute the values of given data,
⇒ 90×x = 18×540
⇒ 90×x = 9720
⇒ x = 9720/90
⇒ x = 108
Hence, the value of x is 108.

This sequence is the numbers 5, 6, 7, 8, 9, and 10 squared.
Work out the cube root of 343, then square it.
49
Since 7 cubed equals 343, then 7 squared is 49.
When you subtract one square number from another the answer is 7.

Solve the system using the elimination method.
2x + 2y + 5z =−1
2x − y + z =2
2x + 4y − 3z =14
What x,y, and z?
Answer:
x=151/64 y=9/8 z=-51/32
Step-by-step explanation:
2x+2y+5z- (2x-y+z)=-1-2
3y+4z=-3
2x+2y+5z- (2x+4y-3z)=-1-14
-2y+8z=-15
We have two equations 3y+4z=-3 and -2y+8z=-15 (We get it due to elimination method)
3y+4z=-3 (2)
-2y+8z=-15 (-3)
6y+8z=-6
6y-24z=45
(6y+8z)- (6y-24z)= -6-45
32z=-51
z=-51/32
3y-204/32=-3
3y= -96/32+204/32
3y=108/32
y=36/32=9/8
2x+2*9/8+5*(-51/32)=-1
2x+9/4-255/32=-1

An ice cream truck driver used the equation Y=KX to show how much money he made selling 9 ice cream bars. He determined he'd make $24.93. How much did he make per bar sold?
Answer:
$2.77 per bar sold
Step-by-step explanation:
Hi there!
We're given that selling 9 ice cream bars could make the truck driver $24.93. To find how much he'd make per bar sold, divide $24.93 by 9 ice cream bars:
24.93 ÷ 9 = 2.77
Therefore, the truck driver would make $2.77 per bar sold.
We could also find this answer using the given equation, y=kx.
y=kx
Let y equal the earnings. Let x equal the number of ice cream bars sold. Let k equal how much the driver would make per bar sold.
24.93=k(9)
24.93=9k
x=2.77
I hope this helps!
