Answer:

Step-by-step explanation:

$v=\dfrac{d}{t}\\\\v-\text{average speed}\\d-\text{distance}\\t-\text{time}\\\\d=vt,\ t=\dfrac{d}{v}\\\\\bold{Candice:}\ v_C=35\ mph,\ d_C,\ t_C\\\\\bold{Liz}:v_L=50\ mph,\ d_L,\ t_L=t-3\\\\\bold{Equation}:\\\\/\text{the distances are the same}/\\\\d_C=d_L\\\\d_C=v_Ct_C,\ d_L=v_Lt_L\\\\35t_C=50(t_C-3)\qquad\text{use the distributive property}\\\\35t_C=50t_C-150\qquad\text{subtract}\ 50t_c\ \text{from both sides}\\\\35t_C-50t_C=50t_C-50t_c-150\\\\-15t_C=-150\qquad\text{divide both sides by (-15)}$

$\dfrac{-15t_C}{-15}=\dfrac{-150}{-15}\\\\t_C=10\\\\t_L=10-3=7$

I would say to do 637000-437000, which is 200000, and then do 200000/637000. You get 0.314, and the percentage of that in hundreds is 31%.

Solve the system of equations. \begin{aligned} &-9y+4x - 20=0 \\\\ &-7y+16x-80=0 \end{aligned} −9y+4x−20=0 −7y+16x−80=

bekas [8.4K]

Answer:

(5 , 0)

Step-by-step explanation:

7 * (−9y+4x−20)=0

9 * (−7y+16x−80)=0

-63y + 28x -140 = 0 ......a

-63y + 144x -720 = 0 .....b

b-a: 116x - 580 = 0

116x = 580

x = 5

y = (4x-20)/-9 = 0/-9 = 0

Answer:

2, 3, ,6 ,9. (YOUR ANSWER)

All numbers listed below!

15282 ÷ 1 = 15282

15282 ÷ 2 = 7641

15282 ÷ 3 = 5094

15282 ÷ 6 = 2547

15282 ÷ 9 = 1698

15282 ÷ 18 = 849

15282 ÷ 27 = 566

15282 ÷ 54 = 283

15282 ÷ 283 = 54

15282 ÷ 566 = 27

15282 ÷ 849 = 18

15282 ÷ 1698 = 9

15282 ÷ 2547 = 6

15282 ÷ 5094 = 3

15282 ÷ 7641 = 2

15282 ÷ 15282 = 1
