Answer:
Step-by-step explanation:
- 2 ≤ x ≤ 1
x ∈ [ - 2 , 1 ]
L = B + 105
H = L + 24.....H = B + 105 + 24 ...H = B + 129
H + L + B = 324
(B + 129) + (B + 105) + B = 324
3B + 234 = 324
3B = 324 - 234
3B = 90
B = 90/3
B = 30 <==Bart's marbles
L = B + 105
L = 30 + 105
L = 135 <=== Lisa's marbles
H = B + 129
H = 30 + 129
H = 159 <=== Homer's marbles
Answer:
k = -
Step-by-step explanation:
Given
h(k + 6) = 3h - k ← distribute parenthesis on left side
hk + 6h = 3h - k ( add k to both sides )
hk + k + 6h = 3h ( subtract 6h from both sides )
hk + k = - 3h ← factor out k from each term on the left side
k(h + 1) = - 3h ( divide both sides by (h + 1) )
k = -
