Answer:

x = -7

Step-by-step explanation:

4x-9 = 7x+12

Add 9 to both sides

4x = 7x + 21

Subtract 7x from both sides to further isolate the variable

-3x = 21

Divide both sides by -3

x = -7

Plug the value in to check your work:

4(-7) - 9  ?  7(-7) +12

-28 - 9   ?  -49 + 12

-37   ?   -37

-37 = -37

A science teacher has a supply of 50% sugar solution and a supply of 80% sugar solution. How much of each solution should the te
mash [69]
How much of each solution should the teacher mix together to get 105 ML of 60% sugar solution for an experiment?

1. Look at how 60% is closer to the solution of lower concentration (50%). You can deduce that you will be mixing a higher volume of the 50% solution.

2. All 4 answers add up to 105ml.

3. The intuitive answer is the first option:
70 ML of the 50% solution and 35 ML of the 80% solution

4. Let's check whether point 3 is true.
70ml/105ml X 0.5 + 35ml/105ml X 0.8 = (35 + 28)/105= 63/105= 60% / 105 ml = 105ml of 60% sugar solution

ehidna [41]

Answer: 125

Step-by-step explanation:

4/25 = 20/Y

Cross multiply to get the equation

4Y = 500

Divide both sides by 4
