(1.5 + x) / 2 = 2 .... multiply both sides by 2
1.5 + x = 2 * 2
1.5 + x = 4
x = 4 - 1.5
x = 2.5 meters per second
Answer:
6 x 4 = 24
Step-by-step explanation:
Answer:
22, -6
Step-by-step explanation:
Create a system of equations.
x= the larger number
y=the smaller number
Using what you know, create the equations:
x+y=16
3x-y=72
Now add the two equations together. (elimination method)
x+y=16
+ 3x-y=72 (the y's cancel out)
-----------------
4x = 88 Divide.
x = 22
Now plug in x=22 into one of your equations to solve for y.
x+y=16
22+y=16
y=-6
The numbers are 22 and -6.
Answer:
27/220.
Step-by-step explanation:
To get £2.50 Pita has to take two pound coins and one 50p coin.
The probability of picking £1 then £1 then 50 p = 3/12 * 2/11* 9/10
= 9/220.
The number of possible arrangements of 2 pounds and 1 50p
= £-£-50, £-50-£ and 50-£-£.
= 3
So the required probability = 3 * 9/220
= 27/220.
