What is a Fraction ?
A fraction is written as p/q , where q
0
It is asked to determine the sum of the fraction
31/4 + 17/3 + 8/18
Taking the LCM of 4 , 3 , 18
LCM of 4 , 3 ,18 is 36
Therefore

(279+204+16) /36
499 / 36

Therefore the best estimate of the sum of the expression given is

Answer:
a. 11x + d
b. 15m + 10n
Step-by-step explanation:
a. 2(4c+5d) + 3(x-3d)
Break the brackets:
2*4c + 2*5d + 3*x - 3*3d
= 8x + 10d + 3x - 9d
Collect like termsL
= 8x + 3x + 10d - 9d
= 11x + 1d
b. 6(3m+n) - 4(m-n)
Break the brackets:
= 6*3m + 6*n - 3*m - 4*(-n)
= 18m + 6n - 3m - (-4n)
= 18m -3m + 6n + 4n
= 15m + 10n

Answer:
a person travel 50 ft from the bottom to the top of the escalator
Step-by-step explanation:
An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle
The escalator forms a right angle triangle
opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse
let x be the hypotenuse


a person travel 50 ft from the bottom to the top of the escalator
