Let m Z1=(3x)º, m 22=(5x-7)", m 23=(4x+15), and m ZAFD=128º. Find m44 and m ZBFD.

olga55 [171]

Answer:

m<4 = 52°

m<BFD = 98°

Step-by-step explanation:

m<1 = (3x)°

m<2 = (5x - 7)°

m<3 = (4x + 15)°

m<AFD = 128°

✔️Find m<4:

m<4 = 180° - m<AFD (angles on a straight line)

Substitute

m<4 = 180° - 128°

m<4 = 52°

✔️m<BFD = m<2 + m<3

Substitute

m<BFD = (5x - 7)° + (4x + 15)°

We need to find the value of x.

Create an equation to find x.

m<1 + m<2 + m<3 = m<AFD (angle addition postulate)

Substitute

3x + 5x - 7 + 4x + 15 = 128°

Add like terms and solve for x

12x + 8 = 128

12x + 8 - 8 = 128 - 8

12x = 120

12x/12 = 120/12

x = 10

m<BFD = (5x - 7)° + (4x + 15)°

Plug in the value of x

m<BFD = 5(10) - 7 + 4(10) + 15

m<BFD = 50 - 7 + 40 + 15

m<BFD = 98°

Jocab run 5 miles in 1 1/2 hours. robert runs 3 miles in 45 minutes, or 3/4 hour. who ran the faster

lana [24]

Answer: Robert ran faster than Jocab

Step-by-step explanation:

Convert the improper fraction to a proper fraction

Jocab = 5miles in 1 1/2 hours, therefore, 1 1/2 hours = 3/2 hours, to convert to minute will be 3/2 x 60 = 90 minutes

Robert = 3 miles in 3/4 hours = 45 minutes

If Robert runs 3 miles in 45 minutes, by the end of 90minutes, Robert would have covered 6miles, while Jocab covered 5miles in 90 minutes, therefore, Robert ran faster than Jocab.

Jada, Lin, and Elena are saving money for a trip. Together they saved $120. Jada saved $20 less than Lin. Lin saved 3 times as m

otez555 [7]

Answer:

Jada saved $40, Lin saved $60 and Elena saves $20

Step-by-step explanation:

Let the amount saved by Jada be x

Let the amount saved by Lin be y

Let the amount saved by Elena be z

If together they saved $120, then x+y+z = $120 ......... 1

If Jada saved $20 less than Lin, then x = y- 20 .....2

If Lin saved 3 times as much money as Elena, then y = 3z ...... 3

From equation 3, z = y/3 ....... 4

substitute equation 2 and 4 into 1;

x+y+z = $120

(y- 20)+ y + y/3 = 120

2y + y/3 - 20 = 120

2y + y/3 = 120+20

2y + y/3 = 140

multiply through by 3

6y + y = 420

7y = 420

divided through by 7

7y/7 = 420/7

y = 60

Since y = 3z

60 = 3z

z = 60/3

z = 20

From equation 2, x = y- 20

x = 60-20

x = 40

Hence Jada saved $40, Lin saved $60 and Elena saves $20
