79 is 4 below 83 so her next grade needs to be 4 above in order to get an average of 83. The answer is 87.
Step-by-step explanation:
4x=3x
2+4x=3x+2
4x-3x=2-2
1x=0
x=1/0
X=0
(i think the question given was incomplete but this waht i could do with the given statement)
Step-by-step explanation:
step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)
step 2. 15x + 15 = 180 (like terms)
step 3. 15x = 165 (subtract 15 from each side)
step 4. x = 11. (divide both sides by 15)
