11/3 = 3 2/3 as a mixed fraction or proprr fraction
Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = ← k is the constant of variation
y = - x ← represents direct variation with k = -
Answer:
A
Step-by-step explanation:
So we have the equation:
First, let's subtract 16 from both sides:
Now, let's divide both sides by 3:
Remember that with fractional exponents, we can move the denominator into the root position. Therefore:
Let's take the fourth root of both sides. Since we're taking an even root, make sure to have the plus-minus symbol!
Cube both sides. Since we're cubing, the plus-minus stays.
Add 4 to both sides.
Calculator:
So, our answer is A.
And we're done!
Answer:
9 Model As.
Step-by-step explanation:
Let A represent Press A and let B represent Press B.
So, they own 14 total presses. This means that:
They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:
This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:
Substitute this into the second equation: "
First, we can divide everything by 5 to simplify things:
Distribute the left:
Combine like terms:
Subtract 196 from both sides:
Divide both sides by -3
So, the company has 5 Model B presses.
Which means that the company has 14-5 or 9 Model A presses.
And we're done!
Attached is the solution, long division is hard to type out.
