Step-by-step explanation:
Your question isn't complete but let me help out based on the information given.
Joshua's recipe for chili requires 2 3/4 pounds of beef. Sondra's recipe for chili requires 2 2/3 pounds of beef.
The pounds of beef required by both of them will be:
= 2 3/4 + 2 2/3
= 2 9/12 + 2 8/12
= 4 17/12
= 4 + 1 5/12
= 5 5/12
The difference in the pounds of beef required by both of them will be:
= 2 3/4 - 2 2/3
= 2 9/12 - 2 8/12
= 1/12
Also, we.can also infer that Joshua recipe for chili requires more pounds of beef than that of Sondra
Substitute X or Y With 0 So It Would Be 3/5(0) +1/2y = 30
1/2y=30
Divide Get Y And Do The Same For X
Answer: 85 student tickets, 65 adult tickets.
Let's say the # of students is x and the # of adults is y. The two equations we get are 7.50x + 15y = 1612.50 and x + y = 150
x = 150 - y
7.5(150-y) + 15y = 1612.5
1125-7.5y+15y=1612.5
7.5y=487.5
y=65
x=150-65
x=85
Hope this helps!
Let A represent amount of Type A coffee pounds used.
Let B represent amount of Type B coffee pounds used
A + B = 156
B = 156 - A
A = 156 - B
5.80A + 4.65B = 826.60
580 (156 - B) + 4.65B - 826.60 = 0
904.8 - 5.80B + 4.65B - 826.60 = 0
904.8 - 1.15B - 826.60 = 0
78.2 - 1.15B = 0
78.2/1.15 = 1.15B/1.15
68 = B
B = 68 pounds of Type B coffee
There's many more steps you can take to check and etc but am too lazy to put down sorry.
The diary farmer should use 1000 pounds of 85 % protien and 55 % of 200 pounds to make 1200 pounds of a high-grade 80% protein ration
<em><u>Solution:</u></em>
Let the amount of 85 % protien supplement be "x"
Then amount of 55 % protien be (1200 - x)
According to given question,
85 % of "x" protien supplement + 55 % of 1200 - x protien used to get 80 % of 1200 pounds
85 % of x + 55 % of (1200 - x) = 80 % of 1200
Pounds of 85 % protien used = 1000 pounds
Then pounds of 55 % protien used = 1200 - 1000 = 200 pounds
Thus he should use 1000 pounds of 85 % protien and 200 pounds of 55 % protien to get 1200 pounds of a high-grade 80% protein ration
