Answer: b
explanation: only choice B equals -9 like the given equation.
Answer:
the answer is c = (ad)/b
Step-by-step explanation:
See the picture
Each hot dog is x, and costs $4. Each soda is y, and costs $3.
A.
4x + 3y = 33
B.
4x + 3y = 33
4 * 3 + 3y = 33
12 + 3y = 33
3y = 21
y = 7
7 bottles of soda.
Answer: the length is 87 feet
The width is 40 feet
Step-by-step explanation:
Let L represent the length of the playing field.
Let W represent the width of the playing field.
The playing field is rectangular. The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of a playing field for a certain sport is 254 ft. This means that
254 = 2(L + W)
L + W = 254/2
L + W = 127 - - - - - - - - - - - -1
The length is 47 ft longer than the width. This means that
L = W + 47
Substituting L = W + 47 into equation 1, it becomes
W + 47 + W = 127
2W + 47 = 127
2W = 127 - 47 = 80
W = 80/2 = 40
L = W + 47 = 40 + 47
L = 87
There are 24 people, there are 4 pies and they each get 1/6th, 4x6=26
The entire race was 8 hours. If 3/4th of the race was 6 hours, 6/3=2 meaning 1/4th of the race is 2 hours and the full thing being 8.
