6(times the larger number, y) = (the smaller number, x) +18
6y=x+18
(2 times the larger number) - (the smaller number) = 6
2y-x=6
Answer:
Step-by-step explanation:
Area=(1/2)*base *height
First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20
Final answers:
First car=20 gallons
Second car=35 gallons
Answer: 56 degrees
Step by step:
The three angles in a triangle add up to 180 degrees.
49 + 75 + the third angle = 180
Let’s simplify.
180 - 49 - 75 = the third angle
So, by subtracting, we know that the third angle is 56 degrees!
Hope this helps! Please tell me if I did anything wrong, thank you so much and have a good day!
Sqrt(-108) - sqrt(-3) produces two imaginary terms: -i*sqrt( 36*3) -i*sqrt( 3).
Let's simplify that:
-i [ 6*sqrt(3) - 1*sqrt(3) ] = -i * 5* sqrt( 3) (answer)
