2:12 is an equivalent ratio
Answer:
<u>1. 1/3</u>
Step-by-step explanation:
Slope = Rise/run
=> It rises by 1, then runs by 3
=> Therefore, slope = 1/3
(8 x 40) + (8 X 3)
320+24=344
Answer:
She factored out a 4 from the equation.
Step-by-step explanation:
So our original equation is 12x + 4 = 20x - 12
Anika's first steep of her equation is 3x + 1 = 5x - 3
We know that the terms were not moved around, so the first step was likely multiplication or division.
We also see that a 4 has been factored out of the entire equation, like this:
12x + 4 = 20x - 12
4(3x + 4) = 4(5x - 3)
And these 4's cancel each other out.
So, I conclude that Anika's first step was dividing the entire equation by 4 or factoring out a 4 from the equation.
To solve this problem, set up and solve a system of equations. The variables b and m will represent a bread loaf and milk jug, respectively:

I would solve using substitution. Take one of the equations and set it equal to one of the variables, for example:

Now, plug this into the other equation for m and solve for b:

We now know that a loaf of bread costs $2.50. Plug this value in for b in the first equation and solve for m:

One jug of milk costs $1.50 and one loaf of bread costs $2.50.
