Answer:
100%
Step-by-step explanation:
8x-9y=19
4x+y=-7
Multiply all terms of the 2nd by (9)===> 36x + 9y= 63
add (36x 9y= 63) to the 1st ===> 44x+0y = -44 ===> x=-1
replace x by this value in any of the equation & you'll get y=-3
2.47 + 7.1
7.1 + 2.47
9.57-7.1
9.57-2.47
Answer:
Option B)
Step-by-step explanation:
We are given the following in the question:
Priya uses
cups of flour to make 3 loaves of banana bread.
Thus, we can write the ration of bread to amount of flour used as:

Now, b loaves of banana bread using f cups of flour.
This measurement will follow the same ratio.
Thus, we can write:

Thus, the correct answer is
Option B)

2x-3 > 11 - 5x
2x + 5x > 11 + 3
7x > 14
x > 14/7
x > 2
