Brut [27]

Answer:

1) m<1 = 25

2) m<4 = 155

3) m< 5 = 25

4) m<7 = 25

5) 110

6) 30.5

7) 74

Step-by-step explanation:

x + 155 = 180

x = 25

<4 = 155 because of vertical angle thm

<5 = 25 (congruent to <1) b/c of corresponding angles thm

<7 = <5 (25) because of vertical angles thm

5x + 15 = 8x - 42

-3x = -57

x = 19

5(x) + 15

5(19) + 15 = 110

180 - 110 = 70

3x + x + 4 + 70 = 180

4x + 74 = 180

4x = 106

x = 26.5

x+ 4 = 30.5

180 - 115 = 65

x + 4 + 2x + 65 = 180

3x + 69 = 180

3x = 111

x = 37

2x = 74

In how many ways can five basketball players be placed in three positions?

Georgia [21]

Answer:

10 ways

Step-by-step explanation:

The number of ways in which five basketball players could be placed in three positions is:

5 $C_{3}$ = $\frac{5!}{(5-3)!3!}$

= $\frac{5!}{3!2!}$

= $\frac{5*4*3*2!}{3*2*2!}$

= 5 × 2

= 10

The basketball players can be arranged in 10 ways.

Leo had $91, which is 7 times as much money as Alison had. How much

NARA [144]

Answer:

$7x=91$

$13.

Step-by-step explanation:

Let x represent money that Alison has.

We have been given that Leo has 7 times as much money as Alison had. So the amount of money that Leo has, would be $7x$ .

We are also told that Leo had $91, so we will equate $7x$ with 91 and solve for x as:

$7x=91$

To solve for x, we will divide both sides by 7:

$\frac{7x}{7}=\frac{91}{7}$

$x=13$

Therefore, Alison has $13.
