Divide 2x^4+3x^3-5x+6 by x^2+3x-2 .
2x^4 + 3x^3 - 5x + 6 ÷ x^2 + 3x - 2
= 2x^6 + 3x^5 − 2x^3 − 2x^2 + 6/ x^2

о G Kelly opened a bank account that earns 1.2% simple interest each year. After 7 years, Kelly will earn $126 in interest. How much did Kelly deposit when she opened the account?
Answer:
$1,512
Step-by-step explanation:
1.2% of $126 = $1,512
I really dont l know if this is right but I think it is
Answer:
$15
Step-by-step explanation:
Interest=principle X interest rate X the time(In this case years)
So, $126= p X 1.2% X 7
We first multiply 1.2% by 7 and get .084, then we move the decimal to places to the right and get 8.4.After that we divide $126 by 8.4 and you should get 15.So thats how I got $15 but then again I may be wrong.Hope this works for you =)

Gray read his book on 3 different weeks. On week 1 gray read 234 pages of the book. On week 2 gray readthe same number of pages on week 1. On week 3, he read 100 pages less than he read on week 2. What was the total number of pagesless than he read on week 2
Answer:
602 pages
Step-by-step explanation:
Given that he read his book on 3 different weeks in the manner;
week 1 - 234 pages
week 2 - 234 pages
week 3 - 100 pages less than he read on week 2
This means that the number of pages read on week 3
= 234 - 100
= 134 pages
Hence the total number pages in the book
= 234 + 234 + 134
= 602 pages
Answer:602

Quadratics Help!!! (Number 11)
Answer:
a) 2x + 1, 4x + 7
b) L = 19 cm, W = 7 cm, A = 133 cm^2
Step-by-step explanation:
8x^2 + 18x + 7
ax^2 + bx + c
ac = 8 * 7 = 56
56 = 4 * 14
8x^2 + 18x + 7 =
= 8x^2 + 14x + 4x + 7
= 2x(4x + 7) + 1(4x + 7)
= (2x + 1)(4x + 7)
a) 2x + 1, 4x + 7
b)
2(3) + 1 = 7
4(3) + 7 = 19
A = LW = 19(7) = 133
Write2.1 as a mixed number and as an improper fraction.
Do not try to simplify your answers.
Answer:
2 1/10 and 21/10
Step-by-step explanation:
2.1 is 2 + 0.1 when expanded.
2 is just 2 and then 0.1 as a fraction is 1/10. The mixed number would be 2 1/10.
The improper fraction is just 21/10 (convert the mixed number into improper form).
Converting from mixed number to improper: Multiply the number in the front (in this case 2) by the denominator.
That is 2 x 10 which is 20. Then add that number (20) to the numerator. 20 + 1 is equal to 21.
21 would be our numerator and the denominator would stay the same (10).
21/10 is the improper form.
If a car travels 400 meters in 20 seconds how fast is it going?

~AH1807A box of cereal states that there are 72 calories in a 3 fourth cup serving what is the unit rate for calories per cup? HHow many calories are there in 4 cups? The unit rate is _ calories per cup
Answer:
4 cups = 384 calories ; 1 cup = 96 calories
Step-by-step explanation:
Given that:
3/4 cups = 72 calories
Let Number of calories in 4 cups = x
3/4 = 72
4 = x
Cross multiply
(3/4)x = 72 * 4
(3/4)x = 288
Multiply both sides by 4/3
(3/4 * 4/3)x = 288 * 4/3
x = (288 * 4) /3
x = 384
Hence, 4 cups has 384 calories
Number of calories per cup :
4 cups = 384 calories
1 cup = 384 / 4
1 cup = 96 calories

Caden biked 1 2/5 miles in 1/4 hour. If it is currently 4:00 P.M. and he has to bike 14 miles. At what time will he be finished?
Answer:
He will finish the biking at 6:30 pm
Step-by-step explanation:
1/4 hour is same as 1/4 * 60 = 15 minutes
1 2/5 miles is same as 1.4 miles
He bikes 1.4 miles in 15 minutes
then he will bike 14 miles in 15 * 10 = 150 minutes
150
minutes is same as 2 hours 30 minutes
Adding this to 4 pm, we will get;
6:30 pm

what is the answer to 22 +10X=
Complete question:
what is the answer to 22 +10x = 0
Answer:
the value of x is -2.2
Step-by-step explanation:
Given;
22 +10x = 0
collect like terms
10x = 0 - 22
10x = -22
divide both sides by 10
[tex]\frac{10x}{10} = \frac{-22}{10} \\\\x = -2.2[/tex]
Therefore, the value of x is -2.2

A deli owner sold 90 sandwiches in one day. Of those sandwiches, 36 were pastrami. Write an equation to show what percent of sandwiches sold were pastrami
Answer:
36/90 * 100 = p
(p is percent sold that were pastrami)
Step-by-step explanation:
First, 36/90 (part over whole), simplifies to 40/100. We can multiply that by 100 to get a percentage. And that is your equation.
