Answer: Yes
Step-by-step explanation:
2x+8y=6
-8y -8y
2x = -2y
Divide by two so x will be by itself, so the answer will be -1y.
5x+20y=2
-20y -20y
5x = -18y
Divide by 5 so x will be by itself, so the answer will be -3y.
The inequality for this situation is given by 50 + p > 85
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the relationship between two or more numbers and variables.
Let p represent number of pages from Monday to Friday.
Jerome wants to have read at least 85 pages by the end of the day on Friday, hence:
50 + p > 85
The inequality for this situation is given by 50 + p > 85

Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
3(x - 2) = 2(x + 1)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 3x - 6 = 2x + 2
- Subtract 2x on both sides: x - 6 = 2
- Add 6 to both sides: x = 8
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 3(8 - 2) = 2(8 + 1)
- Subtract/Add: 3(6) = 2(9)
- Multiply: 18 = 18
Here we see that 18 does indeed equal 18.
∴ x = 8 is a solution to the equation.
Answer:
Jackson eats 15/2 cups of food in 5 days.
Step-by-step explanation:
If Jackson eats 3/4 of food in the morning and at night then he eats 3/2 of food a day or 1.5 cups of food a day.
1.5*5 = 7.5
OR
3/2*5=15/2
Hope this helps!!
Answer:
7
Step-by-step explanation:
If we call the number of worms in a can x, we can write:
4x + 3x + 2 + 2x = 65
9x + 2 = 65
9x = 63
x = 7 worms
