Multiply the first equation by -7 and the second equation by 8, and then add. Then the correct option is B.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The system of the linear equations are given below.

8s – 9t = 15 …1

7s – 2t = 12 …2

Multiply the first equation by -7 and the second equation by 8, and then add.

–56s + 63t = -105

<u>   56s – 16t = 96  </u>

             47t = -9

Then the correct option is B.

More about the linear system link is given below.

Costa is planning a lunch banquet. The equation C=450+28g models the relation between the cost in dollars, C, of the banquet and
algol13

Answer:

When the number of guests is 0, the cost would be $450.

Step-by-step explanation:

We have been given an equation C=450+28g, which models the relation between the cost in dollars, C, of the banquet and the number of guests, g.

We can see that our given equation in slope-intercept form of equation y=mx+b, where, m represents slope of line and b represents y-intercept or initial value.

We can see that slope for our given equation is 28 and the C-intercept is 450.

The C-intercept tells us that when there are 0 guests in the banquet, the cost would be $450.

Please help! Its due today!
Helga [31]

Answer:

don't know if this is the right way butttt i'm going to give it a shot

Step-by-step explanation:

Cost: I'm guessing this is for the rent for the shoes or is the total cost?

Bowler World: 5 + 1.1g = c | c + 1.1g = t {(this is the other option) probs not correct}

Lucky Spares: 3 + 1.5g = c | c + 1.5g = t

K so personally you should choose option 1 (for example: 5 + 1.1g = c), i have no idea how the proper format is supposed to be

either i hope this helps :)

What is one-fourth of four sevenths
AlekseyPX
1/4  x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28

that leaves you with 4/28. But you have to reduce.

4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7
