Answer:
________
Step-by-step explanation:
Given
Line up the numbers
Multiply the top number by the bottom number one digit at a time starting with the ones digit left(from right to left right)
Multiply the top number by the bolded digit of the bottom number
Multiply the bold numbers: 1×4=4
Multiply the bold numbers: 2×4=8
Multiply the top number by the bolded digit of the bottom number
Multiply the bold numbers: 1×1=1
Multiply the bold numbers: 2×1=2
Add the rows to get the answer. For simplicity, fill in trailing zeros.
adding portion
Add the digits of the right-most column: 4+0=4
Add the digits of the right-most column: 8+1=9
Add the digits of the right-most column: 0+2=2
Therefore,
________
Answer:
Cost to pave the road = $4257
Step-by-step explanation:
Area of the pavement = Area of the outer circle - Area of the internal circle
Area of the outer circle = πr²
= π(55)²
= 3025π square feet
Area of the inner circle = π(33)²
= 1089π square feet
Area of the pavement = 3025π - 1089π
= 1936π
= 6082.12 square feet
Cost of pavement = $0.70 per square feet
Therefore, cost of 6082.12 square feet = 6082.12 × 0.70
= 4257.49
≈ $4257
Cost to pave the road = $4257
2*2=4 first you multiply
4-1=3 then subtract
3+3=6 now you add and that is your answer =6
Answer:
x = 3
Step-by-step explanation:
6x - 4 = 2x + 8
6x - 2x = 8 + 4
4x = 12
x = 12/4
x = 3
