Answer:
147
Step-by-step explanation:
236-89=147
Write the equations,
10 c + 5 f = 6900
5c + 3f = 3660
Double,
10c + 6f = 7320
Subtract,
f = 7320 - 6900 = 420
10 c = 6900 - 5f = 6900 - 2100 = 4800
c = 480
Answer: Cheeseburger 480 calories, fries 420 calories
Check:
10 (480) + 5 (420) = 4800 + 2100 = 6900 good
5(480) + 3(420) = 2400 + 1260 = 3660 good
Answer: 
Step-by-step explanation:
You can see that all numbers greater than and equal to 5 are highlighted on the number line
Therefore, the inequality is: 
A) x+0.25>-8
-0.25 -0.25
x>7.75
B) -1<x-10
+10 +10
9<x
Well, to find the slope of a line, mx + b = y is the formula, and m is slope.
-71 - 2y = 56
We add the 71 on both sides.
-2y = 126
Divide by -2 on both sides.
y = -63
There is no distinguishable slope in this because y equals an integer, not an expression that includes x or m, so the slope is zero.
Hope this helps! (:
