The answer is A
Step-by-step explanation:
speed that she is reading= 3pages/4min
=3/4 page/min
in 30 min she can read= 3/4 page/min × 30min
= 90/4 page
= 22.5pages
Answer:
108 rooms
Step-by-step explanation:
Robin can clean 72 rooms in 666 days
means in 666 days rooms that can be clean is 72 rooms
in 1 days rooms that can be clean is 72/666 rooms
in 999 days rooms can be clean is 999\times 72\div 666
after solving we get 108 answer
Answer:
The number of solutions of an equation is dependent upon the total number of variables contained in it. Thus, the system of the equation has two or more equations containing two or more variables. It can be any combination such as 1. 2 equations in 3 variables 2. 6 equations in 4 variables, and so on Depending on the number of equations and variables, there are three types of solutions to an equation. They are 1. Unique Solution (One solution) 2. No solution 3. Infinite Solutions (Many solutions) The term “infinite” represents limitless or unboundedness. It is denoted by the letter ” ∞ “

The line passes by the points (2,-3) , (-2,5)
so the equation of a line passes by 2 points is (y-y1)/(x-x1) = slope
slope = (y2-y1)/ (x2-x1)
= (5-(-3)) / ( -2-2)
= 8/-4
= -2
then subs. in the 1st equation of the line
(y-(-3)) / ( x-2) =-2
so,, (y+3) = -2(x -2)
so the answer is the 1st one
to make sure ur equation is right subs in the equation by the point (0,1)
if R.H.S = L.H.S
then ur equation is right
