4x-3 is the answer. Hope this helps:)
If x=0 then we have -3y=-7
y=7/3 (0, 7/3) is your first pair
if y=0 then we have 5x=-7
x=-7/5 (-7/5, 0) second pair
now create a graph with these 2 points and any point in the line can be your 3rd pair.
A and B
Both A and B, when simplified get -(1/6), because the others have either 0 or 2 negative signs, denoting a positive end result.
Answer:
A total of 387 centimeters of ribbon are used.
Step-by-step explanation:
We already know that two out of three pieces of ribbon are 1.25 meters.
The third piece of ribbon is 120 millimeters (mm) longer.
1 millimeters = 0.001 meters
120 x 0.001 = 0.12
That means that the third piece of ribbon is 0.12 meters longer than the first two. The length of the third ribbon is 1.25 m + 0.12 m = 1.37 m
In order to find the total number of meters of ribbon used, we need to do addition.
1.25 m + 1.25 m + 1.37 m = 3.87 m
But, the question is asking us the number of centimeters of ribbon that are used.
1 m = 100 cm
3.87 x 100 = 387 cm
Therefore, a total of 387 centimeters of ribbon are used.
Hope this helps! Have a blessed day! :)
Answer:
n = -28
Step-by-step explanation:
-4 = 10 + n/2
first step, subtract 10 from each side to get:
-14 = n/2
cross-multiply to get:
n = -28
