Answer:
105cm
Step-by-step explanation:
Call the rat's height r, the cat's height c and the table height t.
The left part says that
(t + c) - (0 + r) = 120 = t + c - r
c - r = 120 - t
Right part says that (t + r) - (0 + c) = 90 = t + r - c
c - r = t - 90
120 - t = t - 90
2t = 210
t = 105
My god, this is tricky but it's between D and E.
I think it should be e.
The answer is 10. Hope I helped
Answer:
Step-by-step explanation:
Since the boys collected 16 cans each and there are 12 of them it means they collected 16*12= 192 cans in total
there are 15 girls and each collected 14 cans. Therefore they collected 15*14=210 cans in total
210-192=18 cans the girls collected more than the boys
Answer:
x = 17
Step-by-step explanation:
Line l and m are two parallel lines cut across by the transversal line, therefore, the angle measuring 53° and (8x - 9)° are interior angles on the same side. Interior angles on the same side are supplementary.
Therefore:
53° + (8x - 9)° = 180°
Solve for x
53 + 8x - 9 = 180
Collect like terms
53 - 9 + 8x = 180
44 + 8x = 180
Subtract 44 from both sides
44 + 8x - 44 = 180 - 44
8x = 136
Divide both sides by 8
8x/8 = 136/8
x = 17
