Answer: 105 grams
Step-by-step equation: they each eat 21 grams a day
Answer:
y = 4
Step-by-step explanation:
Step 1: Write equation
9/4y - 12 = 1/4y - 4
Step 2: Solve for <em>y</em>
- Subtract 1/4y on both sides: 8/4y - 12 = -4
- Simplify: 2y - 12 = -4
- Add 12 to both sides: 2y = 8
- Divide both sides by 2: y = 4
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9/4(4) - 12 = 1/4(4) - 4
9 - 12 = 1 - 4
-3 = -3
Hi there!
We can begin by solving the inequality using the positive and negative terms:
3y - 1 > 5
Add 1 to both sides:
3y > 6
Divide both sides by 3:
y > 2
Now, solve the negative:
-(3y - 1) > 5
Distribute the -1:
-3y + 1 > 5
Subtract 1 from both sides:
-3y > 4
Divide both sides by -3. REMEMBER to flip the sign.
y < -4/3
'y' has to be LESS than -4/3 and greater than 2, so:
y < -4/3, y > 2
