Answer:
x = 25
Step-by-step explanation:
Since we are trying to multiply 4 by x, we have to divide both sides by 4 to find x.
100 divided by 4 is 25, so x is 25.
To check your answer, we can multiply 4 by 25.
4 × 25 is 100
So, the answer is 25.
Answer:
50g/cm is equal to 5 kg/m
Step-by-step explanation:
as we know that:
10g/cm = 1 kg/m
so,
50g/cm = 5kg/m

Step-by-step explanation:
<u>Step 1: Define equation</u>
x + 5/9x = 2(3 - x)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: x + 5/9x = 6 - 2x
- Combine like terms: 14/9x = 6 - 2x
- Add 2x on both sides: 32/9x = 6
- Divide 32/9 on both sides: x = 27/16
<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>: 27/16 + 5/9(27/16) = 2(3 - 27/16)
- Multiply: 27/16 + 15/16 = 2(3 - 27/16)
- Subtract: 27/16 + 15/16 = 2(21/16)
- Multiply: 27/16 + 15/16 = 21/8
- Add: 21/8 = 21/8
Here we see that 21/8 does indeed equal 21/8.
∴ x = 27/16 is a solution to the equation.
50 km/h = 50,000m / hr
= 50,000 / 60 = 833.333 m / minute
The tire rotates 500 times for this period
So the circumference of the tire = 833.333 / 500 m
= 1.67 m to the nearest hundredth

For both problems, they want you to check their answers. For #1, is the opposite of -12 + 4 eight? For #2, can you split an 8 oz bag into 13 to have 2/3 oz in each bag? If you want the answers I’d be happy to comment. :)
