Answer:
-3
Step-by-step explanation:
y=mx+b
m is slope
The formula for area of a circle is:
A = πr^2
where A is the area and r is the radius which is half the diameter.
Let's plug in values we know and solve:
A = 3.14(11 in)^2
A = 3.14(121 in^2)
A = 379.94 in^2
Answer:
Step-by-step explanation:
Rice: 3 x 10^-2 = 0.03 grams
Salt: 6 x 10^-5 = 6e-5 grams
Answer:
1. The train is will cross the tunnel in 2 minutes.
The train is traveling at 30 km every hour or 60 minutes, so it will move 1 km every 60/30 minutes, or every 2 minutes.
2. Explanation here first: 22 free throws means 22 points and 22 field goals.
184-22=162 points they still needed to get, and
85-22=63 goals they still needed to score
We can now use a system of equations, (where x is 3-point goals, and y is 2-point goals) to solve the problem:
3x+2y=162
x+y=63 (-2)
-------------------------------------------------------------
3x+2y=162
-2x-2y= -126
-------------------------------------------------------------
x=36, and y=27 so the NBA players got 36 3-point goals, and 27 2-point goals
We can check this:
(36*3) + (27*2) + 22 = 108+54+22 = 184 total points

Hope this helps!
Step-by-step explanation:
1- 3x-3= 6 (x-10) organise the terms
2- 3x-3= 6x- 60 calculate (always brackets first)
2- 3x-6x= 3-60 Put the like terms on the correct side. Always put terms with x on the left.
3- -3x= -57 Calculate sums
4- x= -57÷-3=19 Divide
5- x= 19
