Answer:

26 students

Step-by-step explanation:

if one part of the ratio is equal to two people, then it is

2 x 6= 12

2 x 7= 14

14+12= 26

26 students. Because the two new girls only moved the ratio by one number means the ratio is half of how many students there truly are.

50+10(8*1)+2<br> What property do you use to solve this and how.
MissTica
You need to use PEMDAS
So first you do the parenthesis.
8*1=8.
So now re-write the problem.
50+10*8+2
Now you are going to multiply.
10*=80
Now re-write the problem again. 
10+80+2
10+80=90+2=92
So the answer to this problem is 92.

Find the remainder when f(x)=x3−4x2−6x−3 f ( x ) = x 3 − 4 x 2 − 6 x − 3 is divided by x+1
loris [4]

Answer:

The remainder is -2.

Step-by-step explanation:

According to the Polynomial Remainder Theorem, if we divide a polynomial P(x) by a binomial (<em>x</em> - <em>a</em>), then the remainder of the operation will be given by P(a).

Our polynomial is:

P(x) = x^3-4x^2-6x-3

And we want to find the remainder when it's divided by the binomial:

x+1

We can rewrite our divisor as (<em>x</em> - (-1)). Hence, <em>a</em> = -1.

Then by the PRT, the remainder will be:

\displaystyle\begin{aligned}  R &= P(-1)\\ &=(-1)^3-4(-1)^2-6(-1)-3 \\ &= (-1)-4(1)+(6)-3 \\ &= -2 \end{aligned}

The remainder is -2.

I have a few questions!<br> a) x−1.27=4.09<br> b) 2.3−y=2.301<br> c) t+3.04=14.3<br> d) 1.1+k=5.67
maks197457 [2]

Answer:

a.)  x = 5.36

b.)  y = - 0.001

c.)  t =  11.26

d.)  k =  4.57

Step-by-step explanation:

a) x−1.27=4.09

b) 2.3−y=2.301

c) t+3.04=14.3

d) 1.1+k=5.67

Solving. right?

a.)  x = 4.09 + 1.27 = 5.36

b.)  y = 2.3 - 2.301 = - 0.001

c.)  t = 14.3 - 3.04 =  11.26

d.)  k = 5.67 - 1.1  =  4.57
