Can sombody solve this

90 - 43 = x

Step-by-step explanation:

47

Step-by-step explanation:

Dude just subtract 43 from 90, since you are given a 90 degree angle.

But if you need the equation: 43+x-7=90

add 43 and (-7) which gives us 36

new equation is now: 36+x=90

move the 36 to the other side

x=54

now plug it in x(54)-7=47

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
