Answer:
Martina 29, Scott 23 and Jim 69.
Step-by-step explanation:
We are told that:
Martina served six more X orders than Scott (X+6).
So, Scott served X orders.
And Jim served 3 times X order as Scott.
We will have then:
X + (X+6) + 3X = 121
5X + 6 = 121
5X = 121 - 6
5X = 115
X = 115/5
X = 23
So, Scott served 23 orders, Martina 29 and Jim 69.
Answer:
3/8 hours
Step-by-step explanation:
distance=speed/time=120/4=30km
time=distance/speed=30/80=3/8
Answer:
Length = 2 ft
Width = 7/4 ft = 1.75 ft
Step-by-step explanation:
Length of room on blueprint = 1/8 *16 = 2 ft
Width of room on blueprint = 1/8 *14 = 7/4 ft = 1.75 ft
4/20 is 0.20, which is equivalent to 20%.
Remember that 1.0=100%, 0.5=50%, 0.2=20%, 0.05=5%, and so on.
Answer:
4 t - 7 = 2 t+ 13 is the required equation.
The number of race medals Tara has is t = 20 medals.
Step-by-step explanation:
Let the number of medals Tara has = t medals
So, the number of medal Anita has = 4( Medals of Tara) - 7
= 4t - 7
And the number of medals Gary has = 2 times (Medals of Tara) + 13
= 2(t) + 13 = 2t + 13
Now, Annita and Gary has same number of medals.
⇒ 4t - 7 = 2t+ 13
or, 4t - 2t = 7 + 13
⇒ 2t = 20
⇒ t = 20/2 = 10
or t = 10
Hence, the number of race medals Tara has is t = 20 medals
