Answer:
Janine is 28. Ingrid is 30.
Step-by-step explanation:
Let the ages be x and x + 2 for Janine and her sister, respectively.
x/7 + (x + 2)/3 = 14
Multiply both sides by the LCD, 21, to get rid of denominators.
21 * x/7 + 21 * (x + 2)/2 = 21 * 14
3x + 7(x + 2) = 294
3x + 7x + 14 = 294
10x = 280
x = 28
x + 2 = 30
Answer: Janine is 28. Ingrid is 30.
Answer:
$147,000
Step-by-step explanation:
<u>After 1st year:</u>
we need to increase 150,000 by 4%. That means the value would be 150,000 multiplied by 1.04. So:
150,000 * 1.04 = 156,000
<u>After 2nd year:</u>
The new appreciated value of 156,000 will now suffer a loss of 6%. So we need to find the new value by multiplying 156,000 by 0.94 (6% loss). So:
156,000 * 0.94 = 146,640
To the nearest 1000, this would be $147,000
Hello from MrBillDoesMath!
Discussion:
Consider this example:
3 ^ 4 = 3 * 3 * 3 *3 = 81
but it also equals
(1/3) ^ (-4) = 1 / ( 1/3)^4 = 1 / (1/81) = 81
The exponent appears in the denominator. Is this what you meant?
Thank you,
MrB
Answer:
I don't know but I got y= 3x + 5 or -5
Answer:
$13,890
Step-by-step explanation:
One yard equals three feet.
First, add up all your side lengths to get the perimeter.
144+210+345+345+345=1389 ft
In order to get the perimeter in yards you would have to divide 1389 by 3.
1389 / 3 = 463 yrds
With a perimeter of 463 yrds you would have to multiply it by the $30 per yard.
463 x 30= $13,890
So, to fence in a section of land for a horse pasture it would cost $13,890.
