Step-by-step explanation:
<u>Step 1: Define equation</u>
-12(a - 2) = -50
<u>Step 2: Solve for </u><em><u>a</u></em>
- Divide -12 on both sides: a - 2 = 25/6
- Add 2 on both sides: a = 37/6
<u>Step 3: Check</u>
<em>Plug in a into the original equation to verify it's a solution.</em>
- Substitute in <em>a</em>: -12(37/6 - 2) = -50
- Subtract: -12(25/6) = -50
- Multiply: -50 = -50
Here we see that -50 does indeed equal -50.
∴ a = 37/6 is a solution of the equation.
Let's begin by listing out the information given to us:
We start out by observing that Triangles MKR & ACD are similar or proportional
We will solve for the missing side by using the similar triangle theorem. This is shown below:~
I think its equal im not exactly sure so dont blame me if u get it worng :(
To calculate the volume, we use the data given above. For this problem we are asked to convert cups to mL.
volume = ( 2 cups) <span>225 mL / 1 cup = 450 mL
The student's error in converting is that she divide the conversion factor instead of multiplying it, wrote the conversion factor incorrectly and the units of his final answer is wrong.</span>
Answer:
$35
Step-by-step explanation:
divide 25 by 5 to get the unit rate and then take that and multiply that by 7
