Answer:
put a point at (0, 3) and a point at (1, 5). Draw a line through these points and that if your line
Step-by-step explanation:
This is because the y-intercept(b) in the equation y=mx+b is 3. This means the line will cross the y-intercept at (0, 3). NeXT, m is the slope and since it is a positive 2 you could rewrite it as 2/1. Because slope is rise/run just go up 2 units and over 1 unit for every new point on that line.
Step-by-step explanation:
If there are 20 yellow marbles,
there must be 32 - 20 = 12 red marbles.
P(Red marble)
= 12/32
= 0.375.

Hey can anyone help me with my question?
Step-by-step explanation:
PLeAsE its really easy, im in grade 7. I need help with this math question and my teacher didn't tell me the formula.
Hi there!
Mrs. Miller earns a commission of 6% of 179,000
The word "of" is the same thing as a multiplication sign.
6% of 179,000 = 6% × 179,000
6% = 0.06
6% × 179,000 = 0.06 × 179,000
0.06 × 179,000 = 10,740
Your answer is: Mrs. Miller earns $10,740 of commission.
There you go! I really hope this helped, if there's anything just let me know! :)
It takes one pipe x minutes, the other pipe x+3 minutes
the portion filled per minute is by one pipe is 1/x, by the second pipe 1/(x+3)
when two pipes running together:
3&1/3[1/x+1/(x+3)] =1, 1 means the whole cistern
solve for x: 3&1/3(x+3) +3 1/3(x)=x(x+3)
6 &2/3 x +10 =x^2+3x
x^2- (3&2/3) x-10=0
3x^2-11x-30=0
this cannot be factored, so use the quadratic equation:
x is about 5.5
x+3=8.5
