3d - e =7
d + e = 5
-------------
4d / = 12
d=12:4
d=3
3+e=5
e=5-3
e=2
the solution is (3,2)

Answer:
39.375 : 65.625
Step-by-step explanation:
The meaning of "reduce" in this context is unclear. We assume you want to divide the quantity 105 into parts that have a ratio of 3 : 5. Then the smaller part will be 3/(3+5) = 3/8 of the total; the larger part will be 5/8 of the total.
3/8 × 105 = 39 3/8
5/8 × 105 = 65 5/8
The divided quantities are ...
39.375 : 65.625
Consecutive numbers differ by one. So, if
is the first, the three numbers are

The sum of the first and third integer is

______
Answer:
w is the width
L is the length
p is the perimeter
w=9
L=27
___________________
Step-by-step explanation:
p=2[(L-4) + (w+1)]
⇔p=2[(3w-4) + (w+1)]
⇔p=2[4w-3]
⇔p=8w-6
⇔66=8w-6
⇔8w=72
⇔w=9
Then L=3w=27
