X=hamburgers
y=hotdogs

3y+2x=8.00
AND
2y+3x=8.25

Now we've got a system of equations!

Choose a method to solve it, and I think you'll be good from there.

If you need more guidance to the answer, tell me in the comments.

BEST OF LUCK:)

What is 6/5 divided by 4/10
Sidana [21]
Your answer is 0.03 because you have to make the 5 equal to the ten and that would be 10 then change the division to multiplication and just multiply across then you simplify it.

The chemistry class was making 300 gallons of 30% isopropyl alcohol. They mixed 12% with 42%. How much of each did they use?
alexgriva [62]

Answer:

<u>The chemistry class mixed 120 gallons of 12% isopropyl alcohol and 180 gallons of 42% isopropyl alcohol.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of isopropyl alcohol made by the chemistry class = 300 of 30%

Amount of 12% isopropyl alcohol mixed by the chemistry class = x

Amount of 42% isopropyl alcohol mixed by the chemistry class = 300 - x

2. How much of each did they use?

Let's write our equation to solve for x, this way:

30% = 0.3, 12% = 0.12, 42% = 0.42

0.12x + 0.42 (300 - x) = 0.3 * 300

0.12x + 126 - 0.42x = 90

-0.3x = 90 - 126

-0.3x = -36

x = -36/-0.3

<u>x = 120 ⇒ 300 - x = 180</u>

<u>Let's prove x = 120 is correct</u>

0.12x + 0.42 (300 - x) = 0.3 * 300

0.12 * 120 + 0.42 (300 - 120) = 0.3 * 300

14.4 + 75.6 = 90

90 = 90

<u>We proved x = 120 is correct</u>

h circle h(10)

This mean we are to put h in h, the find the function of 10

we have this as;

6-(6-x)

= 6-6 + x = x

Now, replace the x by 10; so we have h circle h(10)
