Answer:
1200
Step-by-step explanation:
60 x
- = -
100 800
There are 2 ways to solve this.
1) 800 x 60= 48,000
Divide by 100= 480
x=480
2) Multiply 60 by 8.
Now there are another 2 ways to go.
1) 480 x
- = -
800 2000
<h2>
OR</h2>
2) 60 x
- = -
100 2000
<h3>
I recommend the second option for both. It is easier. The second option allows you to find and equal ratio, with less of the hassle. </h3>
To get 2000, 100 must be multiplied by 20. So.... multiply 60 by 20 to get a equal ratio.
Your answer is 1200. Meaning 1200 adults cooked dinner more than four nights per week.
I hope this helps you significantly

Answer:
Lets start with d, since its all alone, take 180 - 58 = d, which is 122 = d, next c, 180 - 48 - 58 = c, which is 74 = c, next a, since d is 122, 180 - 122 = a because d + a = 180, a = 58, a + b + c = 180 so, 180 - 58 - 74 = b, b = 48
A=58
B=48
C=74
D=122
