Answer:

The system of equations 8x-3y=10 and 16x-6y=22 has no solution

Step-by-step explanation:

When both of the above equations are put into standard form, you get ...

8x - 3y = 10

8x - 3y = 11

This is an "inconsistent" pair of equations. There are no values of x and y that can satisfy both equations, hence there is no solution.

NeX [460]

Answer:

$43.20

Step-by-step explanation:

If each family member buys one ticket and one lunch, then for ticket price t we have the total expenditure as ...

5(t +6.50) = 248.50

t +6.50 = 49.70 . . . . . divide by 5

t = 43.20 . . . . . . . . . . subtract 6.50

Help me ASAP PLEASE

Answer:

Your(my) number is 40

Step-by-step explanation:

I. Given 80/something, + 13, * 5 = 75 when x is something

So [ $\frac{80}{x}$ + 13 ]5 = 75

[ $\frac{400}{x}$ + 65] = 75

$\frac{400}{x}$ = 75 - 65

$\frac{400}{x}$ = 10

400 = 10x

x = 40

II. Prove by replace 40 in x

[(80/40) + 13]5 = 75

[2 + 13] 5 = 75

(15)5 = 75

75 = 75 true
