Answer:
z = 1/2
Step-by-step explanation:
Step 1: Write equation
22z + 6 - 10 = 6z + 4
Step 2: Solve for <em>z</em>
- Combine like terms: 22z - 4 = 6z + 4
- Subtract 6z on both sides: 16z - 4 = 4
- Add 4 to both sides: 16z = 8
- Divide both sides by 16: z = 8/16
- Simplify: z = 1/2
Step 3: Check
<em>Plug in z to verify it's a solution.</em>
22(1/2) + 6 - 10 = 6(1/2) + 4
11 - 4 = 3 + 4
7 = 7
Answer:
A's
Step-by-step explanation:
Mode is defined as the number, or in this case grade, that appears most often in a set of numbers. Seeing as 10 is the most number of a certain grade recieved, the corresponding grade A is the mode.
Answer:
450 cubic inches
Step-by-step explanation:
the formula to get volume is l×w×h. 12.5×4.5×8=450
1:500000
1cm:500000cm
2:250000
2cm:250000cm
1cm:125000cm
To get this you convert the km into cm as it is easier and then it becomes something like this 2cm : 250000cm
then divide or half to get to the simpler form like this 2cm divided by 2=1cm and 250000cm divided by 2= 125000cm
then put into ratio is 1:125000
