What you need to do is add 6 to 5 (5 + 6). x would be 11.

Solve the following problems using 5-D process part 2
svet-max [94.6K]

The two problems are almost identical: you have to set up a system, and then solve it.

In the first case, let g and b be, respectively, the number of girls and boys.

We know that g=2b+4 (the number of girls in the Spanish Club is four more than twice the number of boys). Also, we know that g+b=61 (there are 61 students in total).

So, we have the system

\begin{cases}g=2b+4\\g+b=61\end{cases}

We can use the first equation to substitute in the second

g+b=61 \iff (2b+4)+b=61 \iff 3b+4=61 \iff 3b=57 \iff b=19

And then solve for g:

g=2b+4=2\cdot 19+4=38+4=42

For the second problem, let c and j be the number of pins knocked down by, respectively, Carrie and John. Just like before, we have the system

\begin{cases}c=j+12\\c+j=230\end{cases}

And you can solve it in the very same way we solved the previous one.

What is the nth term rule of the linear sequence below? 15 , 7 , − 1 , − 9 , − 17 , . . .
Doss [256]

You can see that you're constantly subtracting 8 to get the next number. So, we have

a_1 = 15

a_2 = a_1-8

a_3 = a_2-8 = (a_1-8)-8=a_1-2\cdot 8

a_4=a_1-3\cdot 8

a_5=a_1-4\cdot 8

So, as you can see, to get the n-th term we must subtract (n-1) times 8 from the original number.

Help please I get y=mx+b but I'm not sure how to do this
Fofino [41]

(3,4)  (9,7)

to find the slope

m = (y2-y1)/(x2-x1)

  = (7-4)/(9-3)

3/6

1/2

The slope is 1/2

point slope form

y-y1 = m(x-x1)

y-4 = 1/2(x-3)

distribute

y-4 = 1/2x -3/2

add 4 to each side

y = 1/2 x -3/2 + 4

y = 1/2 x -3/2 + 8/2

y = 1/2 x + 5/2

this is in slope intercept form

Hey 20 points for the first person to show work and answer this​
Harrizon [31]

Step-by-step explanation:

First, the pizza is 18 inches in diameter, so

d = 18

and, because the radium is half of the diameter,

r = 9

<u>Note that the units are inches.</u>

Using the equation

a = \pi  r ^{2}

where a is the area of a circle, we know that the area of the whole pizza is approx.254.5 square inches. Divide by 8 to find the area of 1/8 of a pizza. Each slice will have an area of approx. 32 square inches. For a precise result, the answer is

a(s)=  \frac{(\pi  \times 9^{2})}{s}

where a(s) is the area of a slice of pizza, and s is the total number of slices, given they are equal in size.
