Ainsley walks 3/5 mile in 1/3 of a day. Sarah walks 5/8 mile in 2/6 of a day. Who walked farther, Ainsley or Sarah? Find the unit rate for each girl and then tell who you think walked farther with the correct unit rate given below. *

Answers

[tex]Ainsley \: walked \: in \: \frac{1}{3} \: \: of \: a \: day \ \: = \frac{3}{5} mile[/tex]

[tex] = \frac{1}{3} \times 24 = \frac{3}{5} [/tex]

[tex]8 \: hours = \frac{3}{5} \: miles[/tex]

[tex]Sarah \: walked \: in \: \frac{2}{6} of \: a \: day \: = \frac{5}{8} miles[/tex]

[tex] \frac{2}{6} \times 24 = \frac{5}{8} [/tex]

[tex]8 \: hours \: = \frac{5}{8} \: miles[/tex]

Let us see who walked more :

[tex]Ainsley \: walked \: = \frac{3 \times 8}{40} [/tex]

[tex] = \frac{24}{40} \: miles[/tex]

[tex]Sarah \: walked \: = \frac{5 \times 5}{40} [/tex]

[tex] = \frac{25}{40} \: miles[/tex]

[tex] \frac{24}{40} < \frac{25}{40} [/tex]

Sarah walked farther than Ainsley .

[tex] \frac{25}{40} - \frac{24}{40} = \frac{1}{40} \: miles[/tex]

∴ Sarah walked farther than Ainsley by 1/40 miles .

the question is 7a + 10 = 2a

Answers

Answer:

a = -2

Step-by-step explanation:

Subtract 10 from both sides:

7a + 10 - 10 = 2a - 10

Simplify:

7a = 2a - 10

Subtract 2a from both sides:

7a - 2a = 2a - 10 - 2a

Simplify:

5a = -10

Divide both sides by 5 and simplify:

a = -2

Answer:

A = -2

Step-by-step explanation:

Subtract 10 from both sides:

7a + 10 = 2a -10

Simplify the expression, 7a = 2a - 10

Subtract 2a from both sides next

7a - 2a = 2a - 10 - 2a

Subtract 7a - 2a

5a = -10

5a / 5 = -10/5

a = -2

Simplify Using Distributive Property
-6(2a + 8)

Answers

Answer:

-12a - 48

Step-by-step explanation:

you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48

since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.
