You are able to express numbers in like halves
Step-by-step explanation:
tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.
Therefore 1.6m / (2m + x) = 1/√3
By cross multiplication, 1.6√3 = 2 + x.
Hence, x ≈ 0.77m.
56 + 32 = (8 x 7) + (8 x 4) = 8(7 + 4) (Answer C)
F(-7)=0
Because that makes the (x+7) factor equal zero and any other factor multiplied by zero also results in zero.
A) write an equation you can solve to find the cost of one ticket
x=cost of one ticket.
9x+5=104
b)
I have to solve this equation.
1)adding -5 to each side
2) dividing both sides by 9
c)
9x+5=104
1) 9x+5-5=104-5
9x=99
2) 9x/9=99/9
x=11
the cost of each ticket was $11
