My teacher gave me a number and told me to subtract 5 from the number and then multiply the result by 8. Unfortunately, I wasn't listening. I thought she told me to subtract 8 first and then multiply the result by 5. I did those computations correctly and came up with 70 as my answer. What is the correct answer to the question my teacher actually asked me?
Answers
Answer:
136
Step-by-step explanation:
If you subtracted 8 and multiplied it later 70 divided by 5 is 14 plus 8 equals 22 so 22 was the number I suppose
22 minus 5 equals 17, 17 times 8 equals 136 so the original answer was 136
A kids' movie ticket costs $5.25.
1. One day, 200 kids' tickets were purchased. What was the total cost of those tickets?
2. Ift is the number of kids' tickets purchased, and c is the total cost of those tickets,
write an equation that relates c tot.
3. Another day, the total cost of kids' tickets was $813.75. How many tickets were
purchased that day?
Answers
Answer:
1. $1050
2. $5.25t = c.
3. $813.75 ÷ 5.25 = 155.
Step-by-step explanation:
For the first day, 200 kid tickets were purchased. We know that a singular movie ticket is $5.25. From this information, I know I have to multiply.
200 x 5.25 = 1050.
The answer to number one is $1050.
So t will be the variable that represents the number of kid's tickets and c is the total cost, from this equation, I would create this equation:
$5.25t = c.
I put 5.25 down because that is the cost of a singular child ticket. It would be multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).
The answer to number 2 is $5.25t = c.
Another day, the total cost of the tickets were $813.75. One kid movie ticket is $5.25, so this calls for division.
$813.75 ÷ 5.25 = 155.
The total amount of tickets that were purchased that day was 155 child tickets.
The total amount of tickets that were purchased that day was; 155 child tickets.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that 200 kid tickets were purchased. We know that a singular movie ticket is $5.25.
200 x 5.25 = 1050.
The total cost of those tickets is $1050.
Let t be the variable that represents the number of kid's tickets and c is the total cost, from this equation:
$5.25t = c.
Now multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).
The answer is $5.25t = c.
On another day, the total cost of the tickets was; $813.75. One kid movie ticket is $5.25 thus;
$813.75 ÷ 5.25 = 155.
The total amount of tickets that were purchased that day was; 155 child tickets.

The graph below shows the amount of Michael’s paycheck based on a 40 hour work week, plus his commission from sales. Michael earns 50% of the total amount of sales that he makes.
Answers
Answer:
Option B.
Step-by-step explanation:
The graph attached shows the amount of Michael's paycheck based on 40 hour wok along with commission from the sales.
There are two variables plotted on the graph.
On x-axis → Amount of sales
On y-axis → Amount of paycheck he received
Point (0, 100) shows the y-intercept.
Since, y-coordinates show the amount of paycheck, y-intercept will show the amount ($100) at zero sales.
Therefore, Option B will be the correct option.

Can someone please help me solve this question? 7-3r=r-4(2+r)
Answers
Answer:
There is no solution
Step-by-step explanation:
7−3r=r−4(2+r)
Step 1: Simplify both sides of the equation.
7−3r=r−4(2+r)
7+−3r=r+(−4)(2)+(−4)(r)(Distribute)
7+−3r=r+−8+−4r
−3r+7=(r+−4r)+(−8)(Combine Like Terms)
−3r+7=−3r+−8
−3r+7=−3r−8
Step 2: Add 3r to both sides.
−3r+7+3r=−3r−8+3r
7=−8
Step 3: Subtract 7 from both sides.
7−7=−8−7

h(-3) = -11
h(1) = 4(1) + 1

Lake Okeechobee's water level was at sea level in April. In May, the lake's level rose 4 inches and in June it rose 2 more inches. As a result of no rain, the lake's level fell 5 inches in July and 3 more inches in August. Select all the expressions that describe this situation. 4 – 5 4 + 2 – 5 – 3 4 + 2 – (5 – 3) 4 + 2 – (5 + 3) 4 + 2 – (– 5) – (– 3) 4 + 2 + (– 5) + (– 3)
Answers
Step-by-step explanation:
If the lake's level rose 4 inches and in June it rose 2 more inches, the total amount of distance that he rose is (4+2).
Also if the lake's level fell 5 inches in July and 3 more inches in August as a result of no rain, then the total amount of fall will be (5+3).
Change in height of the lake = total rise in distance - Total fall in distance
Change in height of the lake = (4+2) - (5+3) = (5+3) - (4+2) {commutative law}
open the parenthesis
(4+2) - (5+3)= 4+2-5-3 (note that minus times plus will give minus)
Hence the expressions that best describe this situation are;
1. (4+2) - (5+3)
2. (5+3)-(4+2)
3. (4+2) - 5 -3

Step-by-step explanation:
We need to find the slope between a choice of two points in this function table. I'll choose points (5,16) and (10,32) however you can choose any point you want.
To find "m" which is the slope, we need to do the following:
m = (y2-y1)/(x2-x1)
m = (32-16)/(10-5)
m = 16/5
The answer is A) m = 16/5
