An easy way to do it is divide sixty by five , then multiply by four, so your answer is 48.
Answer:
180:300
Step-by-step explanation:
3:5 = x:480-x
1440-3x=5x
1440=8x
180=x
x=180
plug x in to get the answer
Answer:
Step-by-step explanation:
x² + 4x - 1 - x =x² + 4x -x - 1 { bring the like terms together and add}
= x² + 3x - 1
Since angles that are vertical to each other are equal to each other, the first thing I did is set 45 equal to 4x+1 which would look something like this: 45=4x+1
Then I solved for x. First, I subtracted 1 from each side to isolate 4x which would get me to 4x=44. Then I divided each side by 4 to isolate x and get me to my answer which would be x=11.
