Divide by 30
X=8
Answer:
96
Step-by-step explanation:
commom difference = d
a₆ + a₇ = 16
a₅ + a₈ = (a₆ - d) + (a₇ + d) = a₆ + a₇ = 16
a₄ + a₉ = (a₆ - 2d) + (a₇ + 2d) = a₆ + a₇ = 16
Similarly,
a₃ + a₁₀ = 16, a₂ + a₁₁ = 16, a₁ + a₁₂ = 16
so
a₁ + a₂ + ... + a₁₁ + a₁₂ = 6 x 16 = 96
Answer:
b
Step-by-step explanation:
5x +3(x-1) -10x -2x -3
5x +3x -3 -10x -2x -3
8x -3 -10x -2x -3
-2x -3 -2x -3
-4x -6
if this equation is equal to zero then x = -3/2
Answer: she spent $10.21
Step-by-step explanation:
She buys 10 eggs for $0.33 per egg. This means that the total cost of eggs that she bought would be
10 × 0.33 = $3.3
She also buys 3 pounds of beets at a cost of $1.42 per pound. This means that the total cost of of beets that she bought would be
3 × 1.42 = $4.26
Before she leaves, Ms. Littlebird purchases 5/8 lb of spinach, which costs $4.24 per pound. This means that the total cost of spinach that she bought would be
5/8 × 4.24 = $2.65
Total amount that Ms Littlebird spend at the farmers market is
3.3 + 4.26 + 2.65 = $10.21
I don’t know the first part but i think the second part would be 4^11
