2(x-5) + 4x - 7 = 7
2x-10 + 4x -7 -7 =0
6x - 24 = 0
6x = 24
x= 24/6
x= 4
Micah's answer is incorrect because X=4

Answer:
Metallic Balloons = 74
Bunches of Helium Balloons = 38
Step-by-step explanation:
The question basically asks for the number of "metallic balloons" sold and the number of bunches of "helium balloons" sold.
We will do it in our way. Let B be number o metallic balloons and H be number of bunches of Helium balloons.
Since Metallics cost 2 each and Heliums cost 3.5 per bunch and totaled sales is 281, we can write and equation as:
2B + 3.5H = 281
and, since they sold 36 MORE metallic than helium ,we can write an equation as:
B - 36 = H
We can put 2nd equation in 1st one and solve for B first:
B = 74
Now, we find H:
H = B - 36
H = 74 - 36 = 38
H = 38
Answer:
<em>(8, </em><em>0</em><em>), (12, </em><em>4</em><em>), (16, </em><em>8</em><em>)</em>
Step-by-step explanation:
m =
(20, 12)
(4, - 4)
m = = 1
y - 12 = (1)(x - 20)
<em>y = x - 8</em>
y = 8 - 8 =<em> 0</em>
y = 12 - 8 = <em>4</em>
y = 16 - 8 = <em>8</em>
Answer:
Step-by-step explanation:
2x+16= 3(x-9)
2x+16= 3x-27
3x-2x^^
16= x-17
16+17
x= 33
