Let the number of days be x.
Jameer paints 1 wall in 3 days. In 1 day, he paints 1/3 of a wall. In x days, he paints (1/3)x walls.
June paints 2 walls in 5 days. In 1 day, she paints 2/5 of a wall. In x days, she paints (2/5)x walls.
Working together, in x days they paint (1/3)x + (2/5)x walls.
We want to know the number of days they will take to paint 10 walls, so we let the expression equal 10.
(1/3)x + (2/5)x = 10
(5/15)x + (6/15)x = 10
(11/15)x = 10
x = 10 * 15/11
x = 150/11
It will take 150/11 days which is the same as 13.6363... days or approximately 13.6 days.
-2x -4/3 + 1 = 5
-2x = 4+4/3
-2x = (12 + 4)/3
-2x = 5.33
X = - 2.66
Answer:
3 students got a perfect score.
Step-by-step explanation:
Total number of students in Mrs. Grape's class = 90
Number of students who earned an A = 3/10 of 90
= 
= 27 students
Out of 27 students the number of students who got perfect score
= 
= 3 students
3 students got a perfect score.
A vertical translation only is shown, B, because the triangle moves up; vertical means to move something up or down.
Step-by-step explanation:
mass of the object=m=4 kg
the net force exerted on it=F=24N=kgm/s²
the acceleration of the object=a=?
formula for calculating the acceleration=
F=ma
plug in the values
24kgm/s²=4kga
divide each side by 4
24kgm/s²/4 kg=4kga/4kg
a=6m/s²
