3 x 5 = 15 so 30 divided by 15 equals 2. Now 2 divided by 2 equals 1. Now 1 + 1 = 2
Answer:
Tomatoes = 11.5
Onions = 2
Step-by-step explanation:
Andre wants to purchase some onions and tomatoes to make tomato soup. The recipe states that four times the number of tomatoes, , plus five times the number of onions, x, should produce 56 bowls of tomato soup. A different recipe states that two times the number of tomatoes used minus the number of onions used should produce 21 bowls of tomato soup. What is the resulting recipe for the number or tomatoes and onions used in the soup when Andre adds the two recipes together?
Let
Tomatoes = x
Onions = y
Recipe 1:
4x + 5y = 56
Recipe 2:
2x - y = 21
4x + 5y = 56 (1)
2x - y = 21 (2)
Multiply (2) by 5
4x + 5y = 56 (1)
10x - 5y = 105 (3)
Add
10x + 4x = 105 + 56
14x = 161
x = 161 / 14
= 11.5
Substitute x =11.5 into
2x - y = 21
2(11.5) - y = 21
23 - y = 21
-y = 21 - 23
-y = -2
y = 2
Tomatoes = 11.5
Onions = 2
Answer:
Susan's measurements areincorrect. the measurements for sugar is 1 cup and for flour its 3 1/2 cups.
Step-by-step explanation:
(i dont know how to best answer section b but ill do my best)
A) 1/2 cups of sugar X2= 1 cup of sugar
1 3/4 cups of sugar X2= 3 1/2 cups of flour
B) When you have a mixed number like 1 and 3/4 cups like the example above, you are able to convert it into an improper fraction by multiplying the denominator withthe whole number and then addingthe remaining from the numerator. So with 1 3/4 cups:
4X1= 4+3= 7
So now you get 7/4 cups. to turn it back into a mixed number, just reverse the process.
1. 3
2. 4
3. 1/3
4. 1/2
In this case they just multiplied all numbers In the first set by a number to get the second set, just check that each one in the same position gives you the same answer and your good.
