Answer:

x = 3/2

Step-by-step explanation:

Multiply by 3 and solve the resulting 2-step equation.

5 = (1/3)(2x +12)

15 = 2x +12 . . . . . . multiply by 3

3 = 2x . . . . . . . . . . subtract 12

3/2 = x . . . . . . . . . . divide by 2

Wendy jumped 9/10 meters and Judy jumped 10/9 meters. Draw a number line to model the distance of each girls long jump. Who jump

romanna [79]

Well if you were to draw a number line from 0 to 2, 9/10 will be placed right before 1. 10/9 will be placed after one. Wendy jumped the shorter distance.

There were 4342 buttons altogether in three bags, A, B and C. There were 18 more buttons in Bag B than in Bag A. There were 3 ti

Nutka1998 [239]

Answer: there were 854 buttons in bag a

Step-by-step explanation:

4342 = a + b + c

b = a + 18

c = 3b

4342 = a + (a + 18) + 3(a + 18)

4342 = a + a + 18 + 3a + 54

4342 = 5a + 72

-72 -72

4270 = 5a

/5 /5

854 = a

Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x

andrew-mc [135]

Answer:

MN = 4

Step-by-step explanation:

Given that L, M, N are collinear,

LN = 9,

MN = 4x

LM = 5x

Required:

Length of MN

SOLUTION:

To calculate the numerical length of MN, we need to find the value of x.

To find the value of x, generate an equation to solve for x as follows:

$LM + MN = LN$ (segment addition postulate)

$5x + 4x = 9$ (substitution)

Solve for x

$9x = 9$

Divide both sides by 9

$\frac{9x}{9} = \frac{9}{9}$

$x = 1$

MN = 4x

plug in the value of x

MN = 4(1) = 4
