His mistake is that he used the differences of 6, 10 and 14 instead of the differences of 7, 17 and 31.
i.e. for a linear function, the y values should have a constant rate of change and not the differences.
10% of 25,000 is 2500 so it would take him 25 months to have enough money for a down payment
Solve <span>6x+4x-6=24+9x. Combine all the x terms on one side and all the constants on the other:
10x-9x = 24+6, or x = 30. ONE soution.
Solve </span><span>4x+8=2x+7 +2x-20. Combine all the x terms on one side and all the constants on the other: 4x - 2x - 2x = 7 - 20 - 8 => 0 = -21
This is NEVER true, so </span><span>4x+8=2x+7 +2x-20 has NO SOLUTION.
Please try solving equation B yourself. Then I'd gladly comment on your work.</span>
Answer:
- 8
units
Step-by-step explanation:
<u>We know that:</u>
<u>We can find one side by distance formula:</u>
- a =
- a =
<u>Then the perimeter is:</u>
- P = 4*2 = 8 units
Answer:
3/4 = 16/x. Step-by-step explanation: Set up the original ratio: 3:4 (a.k.a. 3/4 or 3 to 4) Because 16 correlates to red paint and 3 correlates to red paint the will be in the same location (as the numerator or denominator).. Also, the amount of blue paint is unknown so that is x.4 also represents blue paint, so 4 and x will also be on the same level (as the numerator of denominator).
