17) 3*5 + 4 = 19
18) 2 * 3 = 6
19) 3 * 36 + 2 * 6 + 1 = 121
20) 5 * 49 + 6 * 7 = 287
21) 6 * 64 + 6 * 8 + 6 = 438
22) 1 * 81 = 81
23) 1 * 8 + 1 * 4 = 12
24) 7 * 729 + 5 = 5108
25) 1 * 1296 + 5 * 216 + 2 * 36 = 2448

Would anyone help With these questions it's the last one I don't know how to do them 1,2,3,4,5 and 6

Shtirlitz [24]

Answer:

See below

Step-by-step explanation:

1. Use x to designate the number of hours worked.

Plumber 1 = 35(x) + 25

Plumber 2 = 40(x)

Now you need to find when these two equations are equal to each other.

35(x) + 25 = 40(x)

Solve for x.

25 = 40x - 35x

25 = 5x

5 = x

So when the service call equals 5 hours, both plumbers will charge the same amount of money.

2. Use x to designate the number of months.

Center 1 = 30x

Center 2 = 22x + 80 initiation fee

Now you need to make the two equations equal to each other and solve for x.

30x = 22x + 80

30x - 22x = 80 or 8x = 80

x = 10 months

3. Use x to designate the pounds of the package

Shipper 1 = 14 + 2x

Shipper 2 = 20 + 1.5x

Make the two equations equal to each other.

14 + 2x = 20 + 1.5x

2x - 1.5x = 20 - 14

0.5x = 6

x = 12 pounds

4. Deanna $15 using $0.75 per game. This means she can play a total of 20 games before having $0.

Lise $13 using $0.50 per game. This means she can play a total of 26 games before having $0.

So since both end up with $0, you can see that Deanna would play 20 games and Lise would play 26 games.

5. Use x to designate the call time length.

Hotel 1 = 1 + 0.80x

Hotel 2 = 2 + 0.75x

Make both equations equal to each other.

1 + 0.8x = 2 + 0.75x

0.8x - 0.75x = 2 - 1

0.05x = 1

x = 20

6. Use x to designate semesters.

Duke = 22 + 6x

Kila = 4 + 12x

22 + 6x = 4 + 12x

22 - 4 = 12x - 6x

18 = 6x

3 = x semesters

Which statement best describes the triangle formed by joining the points A(-3,6),B(-11,2),C(-4,-2)

Vikki [24]

Answer:

Isosceles triangle

Step-by-step explanation:

Length of side AB = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

= $\sqrt{(-11+3)^2+(2-6)^2}$

= $\sqrt{64+16}$

= $\sqrt{80}$

= 4 $\sqrt{5}$

Length of BC = $\sqrt{(-4+11)^2+(-2-2)^2}$

= $\sqrt{49+16}$

= $\sqrt{65}$

Length of AC = $\sqrt{(-3+4)^2+(6+2)^2}$

= $\sqrt{1+64}$

= $\sqrt{65}$

Since, AC = BC, ΔABC will be an isosceles triangle.
