Answer:
4r + 4(r + 3) = 68
r = 7 miles per hour
r + 3 = 10 miles per hour
Step-by-step explanation:
distance = rate * time
a)
4r + 4(r + 3) = 68
Distribute
4r + 4r + 12 = 68
8r + 12 = 68
8r = 56
r = 7 miles per hour
r + 3 = 10 miles per hour
Answer: move 7 places to the right and 3 places down
Step-by-step explanation:
To find the answer convert 5 into 5/1. To make it compatible with 3/4 you have to have the same denominator. So to make 5/1 compatible with x/4 you multiply both sides by 4, so it would be 20/4. And then to find how many recipes you can make you would multiply 3 to the highest number it can be that does not exceed 20. The closest 3 can get to 20 before exceeding it would be 6 times. 6/1x3/4 =18/4. So you could make 6 recipes and you would have 2 pounds of potatoes left.
Zoe can make 6 recipies and she will have 2 pounds of potatoes left.
Answer:
The answer is E.
Step-by-step explanation:
Divide it into rectangles
Answer:
Option (1)
Step-by-step explanation:
System of equations has been given as
2x + 6y = 14
By dividing this equation by 2
x + 3y = 7 --------(1)
Second equation is,
-2x + 2y = -10
-x + y = -5 -------(2)
By adding equation (1) and equation (2)
(x + 3y) + (-x + y) = 7 - 5
2x = 2
x = 1
By putting x = 1 in the equation (1)
1 + 3y = 7
3y = 6
y = 2
So, we get exactly one solution pair (1, 2) where these lines are intersecting.
Therefore, the best category that defines the system of equations is Consistent/Independent
Option (1) will be the answer.
