The first number: x
The second number: x + 3
The third number 2 * x - 11
Sum of all numbers: 65
We can write it down as an equation:
65 = x + 3 + x + 2x - 11
65 = 4x + 3 - 11
65 = 4x - 8 / + 8 (both sides)
73 = 4x / ÷ 6 (both sides_
x = 18,25
Doublecheck:
The first number: 18,25
The second number 18,25 + 3 = 21,25
The third number: 2 * 18,25 - 11 = 36,5 - 11 = 25,5
Sum of all numbers: 18,25 + 21,25 + 25,25 = 65, so it's correct :)
Answer:
For the parallel line it will still have a slpoe of 2/3
Step-by-step explanation:
as for the perpendicular line it will be double like 4/6 so it can meet it at a 90° angle.
The answer is LCM of 3 and 9
Answer:
12 fives and 18 tens
Step-by-step explanation:
solving this we need 2 different equations
one for he total bills and one for the total money
x+y=30
that is total bills
5x+10y=240
combining both equations we can use elimination method and get
12 five dollar bills and 18 ten dollar bills
EXPLANATION
Let's see the facts:
The scale is---> 14 milimeters ----> 5 meters
Width = 42 milimeters
Applying the unitary method, the actual width of the pool is:
The width of the pool is 15m
