To eliminate the y terms and solve for x in the fewest steps, by which constants should the equations be multiplied? first equation: 4x − 3y = 34 second equation: 3x + 2y = 17
a. the first equation should be multiplied by 2 and the second equation by 3.
b. the first equation should be multiplied by 2 and the second equation by −3.
c. the first equation should be multiplied by 3 and the second equation by 4.
d. the first equation should be multiplied by 3 and the second equation by −4.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

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
