Answer:
B
Step-by-step explanation:
X=-5, X=4 hope this helps
Write and solve an equation of ratios:
x 9
---- = ----
16 x
Cross mult., we get x^2 = (16)(9)
Taking the sqrt of both sides, we get x = plus or minus (4)(3), or
x= plus or minus 12
Since x is measure of distance here, omit the -12 result. x = +12 units
It factors into (x+4)(x+3)
First, begin by converting the tip of 12% to a decimal.
.12
Now, multiply that by the total bill.
.12*143=17.16
We now know the numerical value of the tip.
Add the tip to the total bill and get your answer.
143+17.16=160.16
