Answer:
Total amount pay for potatoes = 50.2
Step-by-step explanation:
Given:
Levi buys cookies and potatoes
Total amount pay for cookies = 5.49
Total amount pay by Levi = 55.69
Find:
Total amount pay for potatoes
Computation:
Total amount pay for potatoes = Total amount pay by Levi - Total amount pay for cookies
Total amount pay for potatoes = 55.69 - 5.49
Total amount pay for potatoes = 50.2

Step-by-step explanation:
How you find co-terminal is by adding or subtracting 360 degrees to the value you are given.
If it is a positive number like #18. all you do is subtract 510 - 360 = 150 until you get to a value between 0 degrees and 360 degrees.
The same thing applies to negative numbers. Like #21. You will add 360 + (-660) until you get to a number between 0 degrees and 360 degrees.
-660 + 360 = -300 (this is not a value in between 0 and 360 so we must add 360 again)
-300 + 360 = 60 (this is a value in between 0 and 360) (this is the co-terminal angle)
That is the idea of finding co-terminal angles.
Answer:
200,7 miles
Step-by-step explanation:
Proportions:
223 miles ⇔ 10 gallons
D miles ⇔ 9 gallons
D = 223*9/10
D = 200.7 miles
Answers with explanations:
Problem 2-
First we have to insert our numbers into the equation. So we would have
l2l-l-7l
The ll bars mean to find the absolute value. Absolute value is how many spaces it is between that number and zero. So we can simply this to
2-7=-5
Problem 3-
First, we have to insert our numbers into the problem.
2(-2)^3(3)
Using PEMDAS or order of operations, we solve the exponent first and simplify from there
2(-8)(3)
(-16)(3)
(-48)
The answer is -48
Problem 4-
Again, we have to input the numbers into the equation.
(4^2-4(-3))/2
(16-4(-3))/2
(16+12)/2
(28)/2
14
The answer is 14
Problem 5-
(3)(-1)-(-1^2)
(3)(-1)-(1)
-3-1
-4
The answer is -4
Problem 7-
l-3-4l- -3^2
l-3-4l- +9
l-7| - +9
7-+9
-2
The answer is -2
Problem 8-
3(-3)^2-4|-3|+6
3(9)-4|-3|+6
27-4|-3|+6
27-12+6
21
Step-by-step explanation:
equate the equation to zero
x³-6x+11x-6=0
if we replace x with 1
it will result to zero
1³-6+11-6=0
using long Division
as shown in the picture
obtain
x²-5x+6
using factorisation
x²-5x+6
(x²-2x)-(3x+6)
x(x-2)-3(x-2)
x=2
x=3
x=1
