Answer:
<CDG = 118 degrees
Step-by-step explanation:
Alternate interior angles are congruent.
4.5 • 4 is 18
18/12.5 = 1.44
8(10a - 4) + 5a = 5a - 12
8(10a) - 8(4) + 5a = 5a - 12
80a - 32 + 5a = 5a - 12
80a + 5a - 32 = 5a - 12
85a - 32 = 5a - 12
<u>-5a -5a </u>
80a - 32 = -12
<u> +32 +32</u>
<u>80a</u> = <u /><u>20</u>
80 80
a = 1/4
Answer:
50 cents
Step-by-step explanation:
The ratios can be added to find exactly how many of each coffees there are.
3 + 7 + 5 = 15
300 / 15 = 20
20 x 3 = 60 black coffees
20 x 7 = 140 sugared coffees
20 x 5 = 100 milk coffees
Multiply by the price.
60 x 50 = 3000 cents = $30 for black coffee
140 x 60 = 8400 cents = $84 for sugared coffee
100 x ? = 100? cents = $1? for milk coffee
Get rid of the ?.
164 - (30 + 84) = 50
$50 for milk coffee.
$1? = $50
? = $.50
Surely it would be -18y
Because:
6 x 3 = 18 so 6 x -3 would be -18
Then -18 x y would be -18y
