Answer:
20 for both x and y
Step-by-step explanation:
if we substitute 20 for x, we get 2x20 which is 40.
If we substitute 20 for y, we get 4x20 which is 80.
80 plus 40 is 120.
Hence the answer is 20 for both x and y

Associative Property of Multiplication
3 + (5 + 7) = (3 + 5) + 7
Identity Property of Multiplication
3 + 5 = 5 + 3
Identity Property of Addition
5(1) = 5
Commutative Property of Addition
(3 + 5) + 0 = (3+5)
Associative Property of Addition
[ 3(5) (4) = (3) 5(4)]
Answer:
Associative Property of Multiplication
[ 3(5) (4) = (3) 5(4)]
Identity Property of Multiplication
5(1) = 5
Identity Property of Addition
(3 + 5) + 0 = (3+5)
Commutative Property of Addition
3 + 5 = 5 + 3
Associative Property of Addition
3 + (5 + 7) = (3 + 5) + 7
Step-by-step explanation:
The associative property states that you can re-group numbers and you will get the same answer and the commutative property states that you can move numbers around and still arrive at the same answer.
The identity property of 1 says that any number multiplied by 1 keeps its identity.

A spinner with 10 equal sections, numbered 1 to 10, is spun. Then a coin is flipped. What is the probability that the spinner will land on 3 and the coin will land on heads?
12%
20%
5%
10%
Answer:
Step-by-step explanation:(Probability of landing on 3)*(Probability of landing on heads) = (1/10)*(1/2) = (1/20) or 0.05 or 5%
The probability that the spinner will land on 3 and the coin will land on heads is 5%.
Option C is the correct answer.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Sample space of spinning a spun of 10 sections and flipping a coin.
= (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) x {H, T}
= {(1, H), (1, T), (2, H), (2, T), (3, H), (3, T), (4, H), (4, T), (5, H), (5, T), (6, H), 6, T), (7, H), (7, T), (8, H), )(8, T), (9, H), (9, T), (10, H), (10, T) }
The number of possible outcomes = 20.
Number of outcomes with 3 and heads = 1
i.e (3, H)
The probability of landing on 3 and heads.
= 1/20
= 0.05
In terms of percentage.
= 0.05 x 100
= 5%
Thus,
The probability of landing on 3 and heads is 5%.

Zak has 3/5 pack of pencils. Of these, 2/7 are blue. How many blue pencils does Zak have?
Answer:
11/35
Step-by-step explanation:
First, you would have to make a common denominator. To do this, multiply these 2 denominator, 5 and 7. You should get 35. Then, you would have to make the numerator equal to the denominator. In this case, multiply 3 to 7 and 2 to 5. Now you have 21/35 and 10/35. Now subtract 21 from 10, and simplify if needed. I hope this helps!

Boomer, the dog, eats 3/2 kg of dog food each week.
How many grams of dog food will Boomer eat in 4 weeks?
Answer:
Boomer will eat 6,000 grams
Step-by-step explanation:
If you multiply 3/2 by 4, You get 12/2, and if you simplify you get 6 so boomer will eat 6 kilograms in 4 weeks but then you multiply it by 6000 grams. Hope this helps! Sorry if I am late, but I hope you have a great day!
The total quantity of food Boomer, the dog will eat in 4 weeks is 6 kg
Given:
Food eaten per week = 3/2 kg
Number of weeks = 4
Quantity of food eaten in 4 weeks = Food eaten per week × Number of weeks
= 3/2 kg × 4
= (3 × 4) / 2
= 12/2
= 6 kg
Therefore, the total quantity of food Boomer, the dog will eat in 4 weeks is 6 kg
