Answer:

Around 0.22

FIRST THOUGH, I FEEL LIKE 90 MIGHT HAVE MEANT TO BEEN 0.9, SO IF SO SUBSTITUTE THE 90 BELOW FOR 0.9!

Step-by-step explanation:

Okay, so first.

Company A will be 50 a day plus 0.4 a mile

Company B will be 30 a day plus 90 per mile

We can write an equation like this:

50 + 0.4m = 30 + 90m

m = miles they are the same

Then we solve for m.

50 + 0.4m = 30 + 90m

- 0.4m - 0.4m

50 = 30 + 89.6m

- 30 - 30

20 = 89.6m

Divide both sides by 89.6

Around 0.22!

Anne picked out 3 board games from her cabinet to take to a game night with her friends. She still has more than 10 board games

Tresset [83]

Answer:

x - 3 > 10

There were more than

board games in Anne's cabinet to start.

Step-by-step explanation:

The variable x represents how many board games were in Anne's cabinet to start. Since she has already picked out 3 board games to bring, the expression x–3 represents how many board games are still in the cabinet.

And, since Anne has more than 10 board games still in her cabinet, x–3 must be greater than 10.

This inequality shows the relationship.

x–3>10

Now, solve for x.

x–3

> 10

x–3+3

> 10+3 Add 3 to both sides

> 13 Simplify

So, there were more than 13 board games in Anne's cabinet to start.

zaharov [31]

Option D: 14 is the right answer

Step-by-step explanation:

In order to find the value of given expression we have to put the given value for f in the expression

Given expression is:

$f^2+5$

We have to find the value of expression on f=3

So,

putting f=3 in expression

$= (3)^2+5\\= 9+5\\=14$

The value of given expression at f=3 is 14

Hence,

Option D: 14 is the right answer

Use the substitution method to determine the solution of the system of equations. y = -5x and 21x - 7y = 28

8_murik_8 [283]

Answer:

x = 1/2 y = -5/2

Step-by-step explanation:

Since we already know an equation for y, we just need to plug it into the other equation.

21x - 7(-5x) = 28

21x + 35x = 28

56x = 28

x = 1/2

Now that we know x, we substitute it into the other equation, to find y.

y = -5x

y = -5(1/2)

= -5/2
