Kobe,A’mari and DJ are raising money for the football team to take a trip to San Diego.kobe collected $24.55 more than A‘Mari, A
Novay_Z [31]

Answer:

DJ= $39.58

Step-by-step explanation:

KOBE (K)

DJ (DJ)

A'MARI (A)

K= $24.55 + A

DJ= K –$15.60

Total Amount= $125.40

(24.55 + A) + (K – 15.60 + A) + A= 125.40

2A + K + 8.95 = $125.40

2A + K = $116.45

2A + (24.55 + A) = $116.45

3A = $91.90

A= 91.90 ÷ 3

A= $30.63

Therefore,

K= 24.55 + 30.63

K= $55.18

DJ= $55.18 – 15.60

DJ= $39.58

Factor the expression. 4d + 12 Enter your answers in the boxes.
Dmitry_Shevchenko [17]
4d + 12 = 4(d + 3)
Basically, you just need to determine what 4d and 12 have in common.  In this case, they both divide evenly by 4. Therefore 4 (d + 3) = 4d + 12 according to the distributive property.

Sam drove for 2 hours at 45 mph. He has the same distance remaining. How fast should he drive to make his average speed 60 mph?
Goshia [24]
Speed (S) = Distance (D) / time (t)

First stretch

45 = D / 2

D = 45*2

D = 90 mp

How is the same distance:

Second stretch

S = 90 / t

Average speed (AS):

AS = (S1+S2) / 2

60 = [45+(90/t)] / 2

120 = 45+90/t

120-45 = 90/t

75 = 90/t

t = 90/75

t = 1,2 h

________________________

And now:

S = 90 / t

S = 90 / 1,2

S = 75 mph
