304-17= 287.
287 divided by 7= 41 students per bus.

Answer:

There were 41 students in each bus.

Step-by-step explanation:

Consider the provided information.

304 students went on a field trip 7 buses were filled and 17 students traveled in cars.

We need to find How many students were in each bus.

Let the number of students in each bus is represented by x.

Thus the required equation is:

7x+17=304

Subtract 17 from both the sides.

7x=304-17

7x=287

x=41

Hence, there were 41 students in each bus.

Find two consecutive odd integers whose product is 1443
liberstina [14]

Let's x represents the first odd integer

The next consecutive integer would be represented as x+2.

So x and x+2 being multiplied together will give us 1443:

(x)(x+2)=1443

x^2+2x=1443

x^2+2x-1443=0

By solving the quadratic equation using the quadratic formula, x will equal to 37 and -39.

Since the problem says "integers", so I'm assuming two pairs of consecutive integers would be ok.

With that said you 1st pair will be: 37,39

Your second pair will be: -37,-39.

Solve each equation. Check your solution. <br> A) -6a=36<br> B) -9d=-72
vovikov84 [41]
A) -6a = 36

Divide both sides by -6 so that (a) is isolated.

a = -6

Check by plugging in -6 for a.

-6a=36

-6(-6)=36

36=36

So, a=-6

B) -9d=-72

Divide both sides by -9.

d = -72/-9

d = 8

Check work by plugging in 8 for d.

-9d=-72

-9(8)=-72

-72=-72

So, d=8

Someone please explain this question PART "b) i" ONLY!!!
Gnom [1K]
<h3>Answer:   (n-1)^2</h3>

This is because we have a list of perfect squares 0,1,4,9,...

We use n-1 in place of n because we're shifting things one spot to the left, since we start at 0 instead of 1.

In other words, if the answer was n^2, then the first term would be 1^2 = 1, the second term would be 2^2 = 4, and so on. But again, we started with 0^2 = 0, so that's why we need the n-1 shift.

You can confirm this is the case by plugging n = 1 into (n-1)^2 and you should find the result is 0^2 = 0. Similarly, if you tried n = 2, you should get 1^2 = 1, and so on. It appears you already wrote the answer when you wrote "Mark Scheme".

All of this only applies to sequence A.

side note: n is some positive whole number.

За – 6а + 2 = 8а + 20 – 5а
Luda [366]

Answer:

a = -3

Step-by-step explanation:

3a - 6a + 2 = 8a + 20 - 5a

Combine Like Terms

-3a + 2 = 3a + 20

       -2            -2

-------------------------------------

-3a = 3a + 18

-3a  -3a

-------------------------------------

-6a = 18

----   ----

-6     -6

a  =  -3

Write a linear equation for slope: 0; y-intercept: -8
Novosadov [1.4K]

Answer:

x = -8

Step-by-step explanation:

Since there is no slope, there is no need for a y variable to appear in your final equation. The graph will cross y = -8 horizontally. So therefore, x = -8

This is a pretty short explanation, but there's not too much to it. Hope this helped :)
