Answer:
-2x^2-5x+150
Step-by-step explanation:
(x)(-2x) + (x)(15) + (10)(-2x)+(10)(15) <--- multiplying
2x^2+15x-20x+150 <---- solution of multiplication
2x^2 - 5x+150 <------- combine like terms (answer)
Answer:
1 month
Step-by-step explanation:
249 is the amount she spends for buying the kitten, (299-50=249) which she only has to pay once.
20 is the amount she has to spend every month, the rate of change.
The problem can be modeled with the general equation:
y = 20x + 249
In this equation, x the the time in months and y is the amount of money spent.
Substitute 250 for y.
y = 20x + 249
250 = 20x + 249 <= isolate x to get the number of months
1 = 20x
x = 1/20
Carol will only spent money every month, not for 1/20 of a month.
It will only take Carol 1 month to spent $250.
Check answer:
Substitute x for 1
y = 20x + 249
y = 20(1) + 249
y = 269
269 is more than 250 already.
Answer:
<em><u>$541</u></em>
Step-by-step explanation:
1). $550 - $120 = $430 left in her bank account.
2). $430 + $200 = $630 in her bank account.
3). $630 - $89 = $541 left in her bank account.
(Withdraw means removing some of your money out of your bank account, and deposit means putting money back in your bank account)
So, therefore, after all of those transactions, Ms. Lawrence's bank account has <u><em>$541.</em></u>
Hope this helps! <3
6. When one number is a multiple of the other number, that would make the first number the LCM. For example if your first number is 14 and the second number is 2, their first common multiple would be when 2 gets to 14.
2, 4, 6, 8, 10, 12, 14.
14 would be the first time the numbers are equal
5. The first thing to do to find out if 8 is a multiple of 56 is to divide 56 by 8 and see if it comes out to a whole number. 56/8=7
Since 7 is whole, 56 would be the LCM of 56 and 8.
8, 16, 24, 32, 42, 48, 56
Volume of a pyramid= 1/2 * base area * height
