Answer:27
Step-by-step explanation:
3x 11 is 33 and 3 x 5 is 15 then you would do 1 x 2 which is 2 then you would add 2 to 33 which is 35 then subtract 15 which is 20 then add 7 to get 27
Answer:
27
Step-by-step explanation:
First, you do what is inside the parantheses, so 11 - 5 is 6, then you multiply 1 x 2 = 2, and 3 x 6 is 18. Lastly, you add it all up and get the sum of 27. Hope this helps!
a collection of coins consist of nickels, dimes, and quarters. there are 3 fewer quarters than nickels and six more dimes than quarters. how many of each kind of coin is in the collection if the total value of the collection is $4.35?
Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.
Creating a system of equations thus :
n + d + q = 36 - - - (1)n = q + 3 - - - (2).d = q + 6 - - - (3)Substitute for n and q
(q+3) + (q+6) + q = 36
3q + 9 = 36
3q = 36 - 9
q = 27 ÷ 3
q = 9 quarters
n = 9 + 3 = 12 nickels
d = 9 + 6 = 15 dimes
Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.

Fred jumped into a lake from a rock 7 feet above the surface of the water. He sank five feet into the water and continued to swim down two additional feet.
•Sophie stated that the total distance would be 0 because the heights were additive inverses of each other.
•Jake disagrees and thinks that Fred covered 14 feet. He found his answer using a number line.
Do you agree with Sophie or Jake?
Answer:
Sophie
Step-by-step explanation:
Jake is wrong because when he jump he was out of the water and you're supposed to count what he swam in the water so Sophie is correct.

Evaluate: -12x + 2y when x = -2 and y = -1
Evaluate: 10 + a - b when a = -4 and b = -6
Evaluate: -8(n-3) when n = -7
Evaluate: 3 - x + 2(-x + 4) when x = 9
Evaluate: 12 - (15 + y) ÷ 6 - 8 when y = -3
Evaluate: 15 - a(-b) when a = 5 and b = -5
Answer:
1) 22
2)12
3)-80
4)-16
5)-10.5
6)-10
Step-by-step explanation:
-12x + 2y when x = -2 and y = -1
= -12 (-2) + 2 (-1)
= 24 + (-2)
= 22
10 + a - b when a = -4 and b = -6
= 10 + (-4) - (-6)
= 10 - 4 + 6
= 10 + 2
= 12
8(n-3) when n = -7
= 8 (- 7 - 3)
= - 56 - 24
= - 80
3 - x + 2(-x + 4) when x = 9
= 3 - 9 + 2 (- 9 + 4)
= - 6 - 18 + 8
= - 24 + 8
= - 16
12 - (15 + y) / 6 - 8 when y = -3
= 12 - 15 + 3 / 6 - 8
= 12 - 15 + 0.5 - 8
= - 3 - 7.5
= - 10.5
15 - a(-b) when a = 5 and b = -5
= 15 - 5 (5)
= 15 - 25
= - 10

Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board. Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area. Adam says he knows another way. Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board. 1. What is the area of the board shown on the scale drawing? Explain how you found the area. Write your answer in the space below. 2. How can Adam use the scale factor to find the area of the actual electronics board? Remember, he uses a different method than Jason. Write your answer in the space below. 3. What is the area of the actual electronics board? Write your answer in the space below.
Answer:
1. Area is 1800 cm. I found this out by multiplying 36 and 50 together.
2. He can figure out that the scale factor 5:1 means that 1 cm in the drawing is 0.2 cm in reality, so he would take 36 and 50 and multiply them both by 0.2 cm then add them to get 17.2, which is the actual area of the rectangle.
3. Actual area is 17.2
