Let's solve your equation step-by-step.
10d+20=100
Step 1: Subtract 20 from both sides.
10d+20−20=100−20
10d=80
Step 2: Divide both sides by 10.
10d
/10= 80/10
so d= 80
forgot the zero
8. Explain why 30+1 = 6 is the same as 30 -/-/--/-X-X = 0. What is
the value of x in this example?
Answer:
5
Step-by-step explanation:
5 because of two ways one you could do 6*what is 30. Or you could do repeated addition 30=5+5+5+5+5+5. But when you do 30=5-5-5-5-5-5. You are doing repeated subtraction which is equivalent to 30-5*6= 0.

Answer:
9. The rate of change is 2/1 or just 2.
Step-by-step explanation:
Basically, X goes up by 1 every single time. Meanwhile Y goes up by 2 every time. So you put 2 on top, and 1 on the bottom and solve.
[tex]\frac{2}{1}[/tex] or just 2, after solving and getting rid of the 1
Answer:
9. 2
10. -5
Step-by-step explanation:
9. The rate of change/slope can be determined by using the formula [tex]\frac{y_{2}- y_{1}}{x_{2}- x_{1}}[/tex]
In this problem, we can choose many different points. For the sake of simplicity, let's choose the first and last points. So [tex](x_{1}, y_{1})[/tex] is (0,-5) and [tex](x_{2}, y_{2})[/tex] is (4,3).
Plugging it in, we get: [tex]\frac{3-(-5)}{4-0} = \frac{8}{4} = 2[/tex]
10. The initial value of the graph is referring to the y-intercept. In this case, it would be -5.

A manager samples the receipts of every fifth person who goes through the line. Out of 50 people, 4 had a mispriced item. If 1,400 people go to this store each day, how many people would you expect to have a mispriced item?
Answer:
112 people
Step-by-step explanation:
[tex]\frac{4}{50}[/tex] = [tex]\frac{x}{1400}[/tex] write the proportion where x is the number of people with a missplaced time
50x = 5600 cross multipy
x = 112 divide both sides by 50

Answer:
From 12 o'clock position clockwise:
-12
-1
11
12
Step-by-step explanation:
y = -1 (given).
x + y = 11
Plug in -1 for y in the equation (given):
x + (-1) = 11
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 1 to both sides of the equation:
x - 1 (+1) = 11 (+1)
x = 11 + 1
x = 12
x + y = ?
x = 12
y = -1
Plug in the corresponding numbers to the corresponding variables:
12 + (-1) = 12 - 1 = 11
xy = ?
x = 12
y = -1
Plug in the corresponding numbers to the corresponding variables. Note that when you multiply a negative and a positive number, your answer will be negative:
12 * -1 = -12
