**Answer:**

they'll need 200 more cans

The answer is 51.3

Explanation:

You’re finding angle Y, so write the SOH CAH TOA. the two sides your are given are the adjacent side to Y and the opposite side so you use tangent. You then get the equation tanY=10/8 Since you’re finding an angle you use inverse tangent so you get y=tan^-1(10/8) and then put that into the calculator!

**Answer:**

Her salary of 2600 per month doesn't change, what does change is the amount of money she makes dependent upon her dollar amount in sales. She earns 7% of her sales, which is our unknown. And we know that she would like make at least $2900 this month. That means that it's ok to make exactly 2900 and it's of course ok to make more than 2900 but it's not ok to make less than that. So our inequality sign is greater than or equal to. Now let's set it up as an inequality: where of course, as stated earlier, the unknown is her sales in dollars. It doesn't look like you need to solve this.

**Step-by-step explanation:.**

First solve for one variable

solve for a in second eqatn

minus 3x both sides

a=17-3x

sub 17-3x for a in first equaiton

2(17-3x)+2x=18

34-6x+2x=18

34-4x=18

minus 34 both sides

-4x=-16

divide both sides by -4

x=4

sub back

a=17-3x

a=17-3(4)

a=17-12

a=5

a is 5

x=4

WORK SECTION (without thoughts)

2a+2x=18 to a+x=9

a+3x=17

a=17-3x

(17-3x)+x=9

17-2x=9

-2x=-8

x=4

a=17-3(4)

a=17-12

a=5

x=4

a=5
