Answer down below.
Step-by-step explanation:
First of all, you need to start with the second section, which is 2 times -1
Doing that, will result with -2, since a positive times a negative = negative, and 2 times 1 = 2
Then, do -2 minus 4, and that gives you -6

To answer this, you will write and equation in terms of the number of adult tickets sold and then solve for a, the number of adult tickets.
$5a + $3.50s = $2517.50
$5a + $3.50(a + 100) = $2517.50
5a + 3.50a + 350 = 2517.50
8.50a -350 -350
<u>8.5a</u> = <u>2167.50</u>
8.5 8.5
a = 255
The number of adult tickets sold was 255, and the number of student tickets sold was 355 (255 +100).
A = c/sin C, and b by the proportion b/sin B = c/sin C.
a/sin 37° = 4380/sin 109°
a sin 109° = 4380 sin 37°
a = 4380 sin 37°/sin 109° ≈ 2787.8
b/sin 34° = 4380/sin 109°
b sin 109° = 4380 sin 34°
b = 4380 sin 34°/sin 109° ≈ 2590.4
Answer:
x= -9
Step-by-step explanation:
5(x+2)=3x-8
Distributive Property
5x+10=3x-8
Subtract 10 and 3x from each side and add it across the equation to put the like terms together.
5x-3x=-8-10
2x= -18
x= -9
