Answer:
z = 46/13
Step-by-step explanation:
Step 1: Write equation
z + 6 ÷ 13 = 4
Step 2: Solve for <em>z</em>
- Rewrite: z + 6/13 = 4
- Subtract 6/13 on both sides; z = 46/13
Step 3: Check
<em>Plug in z to verify it's a solution.</em>
46/13 + 6/13 = 4
52/13 = 4
4 = 4
The answer to that is -4!!
Answer:
41%
Step-by-step explanation:
5 packs of crayons split among 12 people means we divide 5 by 12.
we can round that decimal number to .41 which can be turned into a percentage by moving the decimals place.
.41 = 41%
Answer:
(-17/13, 10/13)
Step-by-step explanation:
Next time, please include more info regarding what you're supposed to do. I will assume that the instructions said "solve this system of linear equations using elimination by addition and subtraction."
Multiply all three terms of the second equation by -5. Then the system looks like:
5x + 2y = -5
-5X + -15y = -5
Next, combine these two equations:
5x + 2y = -5
-5X + -15y = -5
----------------------
-13y = -10
Dividing both sides by -13 yields y = 10/13.
Substituing 10/13 for y in the second equation, we get:
x + 3(10/13) = 1
Multiplying all three terms by 13 eliminates fractions:
13x + 30 = 13, or 13x = -17. Then x = -17/13, and the solution is
(-17/13, 10/13)
