1. in the distributive -3(2m - 5), one forget to use the positive sign instead of the negative sign.
2. the answer should be -2m + 24
There are 2 angle measurements not identified.
Angle ACB and angle ABC.
To find angle ACB you need to know that a straight line is 180 degrees, so if the angle to the right is 131, the angle to the left (Angle ACB) must be 49 degrees.
To find angle ABC, you need to know that the sum of all 3 angles in a triangle equal 180 degrees, so 180 - (49 + 44) = 87 degrees. Angle ABC is 87 degrees.
Answer:
3y
Step-by-step explanation:
To write an expression, define variable. x will be "another number". This means "one number that is 1/3" is 1/3 * x.
1/3 x represents the smaller number.
To represent the larger number, use the inverse or reciprocal. y will be the smaller number. The larger number will be 3*y or 3y.
It will take 24 minutes until all of them reach the start at the same time.
