Answer:
f the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
Your basic equation if y = mx + b
Convert your equation to the above format: y = -5x -2/3
Now you can see that your slope is -5
9x - 6/5 = -12
Convert -12 to -60/5
9x - 6/5 = -60/5
Add 6/5 to both sides
9x - 6/5 + 6/5 = -60/5 + 6/5
9x = -54/5
divide both sides by 9
x = -6/5
Answer:
22.5 grams of 10% cream is mixed with 37.5 grams of 2 % cream to prepare 60 grams of 5% cream.
Step-by-step explanation:
Let x grams of 10% cream is mixed with y grams of 2 % cream to prepare 60 grams of 5% cream.
So, x + y = 60 ............ (1) and
⇒ 10x + 2y = 300
⇒ 5x + y = 150 ............ (2)
Now, solving equations (1) and (2) we get,
4x = 150 - 60 = 90
⇒ x = 22.5 grams
So, y = 60 - x = 37.5 grams. (Answer)
It is Rong the answer is 2
