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
Answer:
ok so one muffin and one cup of teat cost $2.10 ok now I did guess and check and I got one muffin cost $1.15 and one cup of tea is $.95
1.15*2=2.30
.95*3=2.85
2.30+2.85=5.15

Answer: ok so one muffin and one cup of teat cost $2.10 ok now I did guess and check and I got one muffin cost $1.15 and one cup of tea is $.95
Step-by-step explanation:
$.95
1.15*2=2.30
.95*3=2.85
2.30+2.85=5.15
to a decimal using long division
The friend will get 12 issues for $15.
A ratio indicates the number of times one number contains another.
Given that, the friend pays $1.50 per issue:
$1.5 = 1 issues
$1 = 1/1.5 issues
$15 = (1/1.5) × 15 issues
$15 = 10
Since the friend gets the first two issues free, he will get 10 + 2 =12 issues.
Hence, the friend will get 12 issues for $15.
