90. the total of the small bag is 50 so multiple every set by 5 to get their number in the bigger bag
Answer:
if its addition then it will be 79cm
Answer:
The distance from point A to the line of reflection is the same as the distance from point AGH to the line of reflection. This means that the line of reflection bisects .
1) 4 2 2
2) 5.77 2.89 2.89
3) 7.9 3.95 3.95
Step-by-step explanation:
Answer:
C. (3,15) and (4, 12)
Step-by-step explanation:
Given the system of linear equations
y = -x² + 4x + 12 and y=-3x + 24
Since both equations represents the variable y, we will equate both of the equations together.
Step 1: Equating both equations together we have;
-x² + 4x + 12 = -3x + 24
-x²+3x+4x+12-24 = 0
-x²+7x-12 = 0
x² -7x+12 = 0
x²-4x-3x+12 = 0
x(x-4)-3(x-4)= 0
x-3(x-4) = 0
x = 3 and 4
Step 2: substitute x = 3 and 4 into any of the equations to get the value of y. Using equation 2
when x = 3, y = -3(3)+24
y = -9+24
y = 15
when x = 4, y = -3(4)+24
y = -12+24
y = 12
The solutions yo the system of equations are (3,15) and (4, 12)
We can use a factorial for this:
4! = 4*3*2*1 = 24
There are 24 combinations of 4 numbers.
