Answer:

y = - 7

Step-by-step explanation:

line pass (8, - 7) (- 6, -7)

y = mx + b   m: slope        b: y intercept

m = difference of y / difference of x

m = (- 7 - (- 7)) / (- 6 - 8) = 0 / (-14) = 0  ...  line parallel to x axis

b = y - mx = - 7 - 0*8 = -7

equation : y = -7

maxonik [38]

The equation will be like this,

6.89 + t = 8.00

t = 8 - 6.89

t = 1.11

tips = $1.11

6.89 + t = 8.00

To sum up the total amount of cash and coins you have, first, sort each invoice and coin by denomination. Create a separate stack for each denomination and count how many denominations or coins you have.

For each denomination of banknotes and coins, multiply the number you have by the denomination. For example, if you have 4 out of $ 10, multiply by 4x10 to get $ 40. If you have three $ 5 bills, multiply by 3x5 to get $ 15.

Sum the totals to calculate the total amount.

Answer:

B. 88.8

Step-by-step explanation:

or

trial an error

replace x with each of the numbers and see if it plugs in.

example:

(80.5+71.2)/2=80

151.7/2=80

75.85=80?

false. incorrect

another example:

(88.8+71.2)/2=80

160/2=80

80=80?
