x = -2
−12x−2(x+9)=5(x+4)
Use the distributive property to multiply −2 by x+9.
−12x−2x−18=5(x+4)
Combine −12x and −2x to get −14x.
−14x−18=5(x+4)
Use the distributive property to multiply 5 by x+4.
−14x−18=5x+20
Subtract 5x from both sides.
−14x−18−5x=20
Combine −14x and −5x to get −19x.
−19x−18=20
Add 18 to both sides.
−19x=20+18
Add 20 and 18 to get 38.
−19x=38
Divide both sides by −19.
x=
−19
38
Divide 38 by −19 to get −2.

Let the total number of customers that day be "x"
30% of total customers bought a snack and that is 120.
So we can say:
30% of total (x) is 120
Note: 30% converted to decimal is 30/100 = 0.3
This can be translated to an algebraic equation as:
0.3x = 120
Now, we can solve for x, the total customers:
0.3x = 120
x = 120/0.3
x = 400
Since, 80% bought drink, we find 80% of 400:
80% = 80/100 = 0.8
0.8 * 400 = 320
The store sold 320 drinks and 120 snacks. So drinks outweigh snacks be:
320 - 120 = 200
So,
200 more drinks than snacks

Answer:
(x -4)² +(y +3)³ = 4
Step-by-step explanation:
Each circle is centered on (h, k) = (4, -3). Each circle has a radius 1 unit smaller than the circle just outside of it. The innermost circle shown has a radius of 3, so the next in the pattern of smaller circles will have a radius of 2. The equation for a circle centered at (h, k) with radius r is ...
(x -h)² +(y -k)² = r²
The next circle in the pattern is centered at (4, -3) and has radius 2, so its equation is ...
(x -4)² +(y +3)² = 4
Answer:
y=-1/3x+4
Step-by-step explanation:
1/3x+y=4
y=4-1/3x
y=-1/3x+4
