Answer:

$m=3$

Step-by-step explanation:

$6m+5-3m=7(m-1)$

Combine like terms

$3m+5=7(m-1)$

Distribute the 7

$3m+5=7m-7$

Subtract 3m from each side

$4m-7=5$

Add 7 to each side

$4m=12$

Divide by 4

$m=3$

Anna11 [10]

Responder:

2 1/4 m; 225 cm

Explicación paso a paso:

Dado:

Cortar 9 metros en 4 partes de la misma longitud;

Por lo tanto,

9 metros / 4

= 2,25 metros

Por lo tanto, cada varilla será 2.25 = 2 1/4 m

En cm;

1 m = 100 cm

2,25 metros = x

x = 100 * 2,25

x = 225 cm

If you traveled in space at a speed of 1000 miles per hour, how far would you travel in 7.5 x 10^5 hours? Write your answer in s

Lynna [10]

Basically, every zero a number has to the end, the higher the scientific notation will be. Because 1000 has three zeroes, 10^5 will go to 10^8. So, you will travel 7.5 x 10^8 miles.
