The sum of A and B is 171 and their difference is 35. What are the numbers?
Answers
Answer:
103 and 68
Step-by-step explanation:
Given
A + B = 171
A - B = 35
Add the two expressions to eliminate B.
B + (-B) = B - B = 0
We have
2A = 206
Divide both sides by 2 to isolate A
2A/2 = 206/2
A = 103
Now substitute 103 for A in either expression to get B
Using the first expression , we have
A + B = 171
103 + B = 171
Subtract 103 from both sides
103 - 103 + B = 171 - 103
B = 68
The numbers are 103 and 68
Check
103 + 68 = 171
103 - 68 = 35
Answer:
103 and 68
Step-by-step explanation:
since the difference has to be 35 subtract 35 from 171 (equals 136) then divide it by 2, you get 68 which is your first number, then add 35 back and get 103 for the second number, I hope this helped

111 and 4
The division of the numbers 111 by 4 is given by putting a division sign between the numbers 111 and 4. Then we have
⇒ 111 / 4
⇒ 27.75
The value of the expression 111 / 4 using the division property will be 27.75.

Answer: 9.375 cm
Step-by-step explanation:
From the given picture, it can be seen that the measure of side 'c' in triangle = 1.92 cm
The actual length of 'c' in the triangle = 15 cm.
The scale factor =
Now, the length of side 'a' = 1.2 cm
The actual length of side 'a'
1.5 cm---------------15 cm
1.2 cm--------------- x
x=(1.2 cm*15 cm) / 1.5 cm=12 cm.
answer. a=12 cm.

Option c is correct, puppies to rabbits are the animals which gives the ratio 5:2.
Given that a pet store has 15 puppies12 kittens and 6 rabbits.
We have to find the animals which gives the ratio 5:2
There are 15 puppies and 6 rabbits.
Dividing the number of puppies and rabbits, we get:
Puppies: 15
Rabbits: 6
Therefore, the ratio of puppies to rabbits is 15:6, which can be simplified to 5:2.
