How many minutes did it take him to cover 1 mile? 5 minutes.
Answer:
11 breads
Step-by-step explanation:
Note that:
1 bread recipe = 1 bread
From the above question, we know that:
2/3 cups of walnut = 1 bread
7 1/2 cups of walnut = x breads
Cross Multiply
2/3 cups × x breads = 7 1/2 cups × 1 bread
x breads = 7 1/2 cups × 1 bread/2/3 cups
x breads = 7 1/2 ÷ 2/3
x breads = 15/2 ÷ 2/3
x breads = 15/2 × 3/2
x breads = 45/4
x breads = 11 1/4 breads
Maximum full recipe = 11 breads.
Therefore, the MAXIMUM numbers of full recipe of walnut bread the baker can make is 11 breads.
Answer:
# of students = 393, # of non-students = 104
Step-by-step explanation:
We have a system of equations (# of students = s, # of non-students = n):
1. Total people attended: s + n = 497
2. Total earnings: 2.5s + 4.5n = 1450.5
We can <em>change the first equation to n = 497 - s</em>, and <em>substitute that into the other equation: 2.5s + 4.5(497 - s) = 1450.5</em>
Expand: 2.5s + 2236.5 - 4.5s = 1450.5
Subtract: 2.5s - 4.5s = 1450.5 - 2236.5
Simplify: -2s = -786
Divide: s = 393
Plug into first equation: 393 + n = 497
Subtract: n = 104
Replace x with 3 and y with 6 and see which equation is true.
A) y = 7x - 15
6 = 7(3) - 15
6 = 21 - 15
6 = 6
The point (3, 6) makes the first equation true, so the answer is A). Point (3, 6) does not make any other choice a true equation. Answer is definitely A).
Good job!
Multiply 4 and 2 and then multiply that product by -6
