Can somebody please give me the answer I will mark u brilliant

VARVARA [1.3K]

Answer:

x = 6.7

Step-by-step explanation:

We know that 3.5 + x = 10.2, so if we do inverse operations we can find out the value of x.

10.2 - 3.5 = 6.7

we can check our work by substituing it back in the equation for x

6.7 + 3.5 = 10.2

so now we know that x = 6.7. I hope this helps :)

what is the answer to the volleyball team at blue point high school has saved $680 and the team plans to spend no more then that

zloy xaker [14]

Answer:

6 x + 23 y < $ 680 represents the combinations of x balls and y nets that can be purchased.

Step-by-step explanation:

The number of balls than can be purchased = x

The number of nets than can be purchased = y

Total savings = $ 680

Now, the cost of 1 ball =$6

So, the cost of x balls = x ( cost of 1 ball) = x ( $6) = 6 x

Also, the cost of 1 net =$23

So, the cost of y nets = y ( cost of 1 net = y ( $23) = 23 y

So, the total amount spent on x balls and y nets

= Amount spent on x balls + Amount on y nets

= 6 x + 23 y

Also, the saved amount is $680

⇒ 6 x + 23 y < $ 680

Hence, 6 x + 23 y < $ 680 represents the combinations of x balls and y nets that can be purchased.

A president, treasurer, and secretary, all di erent, are to be chosen from a club consisting of 12 people (whose names are I, J,

Ierofanga [76]

Answer:

There are 220 choices

Step-by-step explanation:

Given

$People = 12$

$Selection =3$ (President, Treasurer and Secretary)

Required

Determine number of selection (if no restriction)

This is calculated using the following combination formula:

$^nC_r = \frac{n!}{(n - r)!r!}$

Where

$n = 12$

$r= 3$

So, we have:

$^nC_r = \frac{n!}{(n - r)!r!}$

$^{12}C_3 = \frac{12!}{(12 - 3)!3!}$

$^{12}C_3 = \frac{12!}{9!3!}$

$^{12}C_3 = \frac{12*11*10*9!}{9!3!}$

$^{12}C_3 = \frac{12*11*10}{3!}$

$^{12}C_3 = \frac{12*11*10}{3*2*1}$

$^{12}C_3 = \frac{12*11*10}{6}$

$^{12}C_3 = 2*11*10$

$^{12}C_3 = 220\ ways$

There are 220 choices
