Answer:
7 grams per pencil
Step-by-step explanation:
49 grams/7 pencils
divided both parts of the fraction by 7 to simplify to the number of grams for just one pencil so you end up with:
7 grams/1 pencil
1) u + 2 = 4
u = 2
2) -5 = s - 3
-2 = s
3) 5/13t = -9
t = -9 × 13/5
t = -39/5
t = -7 4/5
4) 6 = x + 2/3
x = 6 - 2/3
x = 5 1/3
5) 13 + w/7 = -18
w/7 = -18 - 13
w/7 = -31
w = -31 × 7
w = -217
6) 17 = -13 - 8x
-8x = 17 + 13
-8x = 30
x = 30/-8
x = -15/4
x = - 3 3/4

2/3X-6 = -10
2/3x = -4
x = -4 / 2/3 = -6
X = -6
check:
2/3(-6) - 6 = -4 -6 = -10 TRUE
