Answer:

a = \frac{100}{3}

Step-by-step explanation:

We have the following equation:

\frac{1}{2} a + \frac{2}{3} b = 50

If b=50, then:

\frac{1}{2} a + \frac{2}{3}×50 = 50

Solving for 'a':

\frac{1}{2} a = \frac{50}{3}

\frac{1}{2} a = \frac{50}{3}

a = 2\frac{50}{3}

a = \frac{100}{3}

The area of a rectangular patio is 400 square feet. The length of the patio is 9 feet more than its width. Find the length and w
oksano4ka [1.4K]

Answer:

Length: 16 feet

Width: 25 feet

Step-by-step explanation:

Alright so let's set up our system:

The area of a rectangular patio is 400 square feet.: L*W = 400

The length of the patio is 9 feet more than its width: L = W - 9

If you look here, all we need to do now is plug in L and solve.

(W - 9)W = 400

W^2-9W - 400 = 0

You can attempt to factor this in a number of ways. I recommend a factor tree, but however you do that is fine.

(W + 16)(W - 25) = 0

so we have two W values now, 25 and -16. Which one do we pick? We pick 25, because we cannot have a negative Width. That would literally break the universe.

So now we plug in 25 in our second equation to get L:

L = 25 - 9

L = 16

And now we have both our answers!

Monica has $340 in the bank and plans to save $10 per week. is this linear or exponential?
riadik2000 [5.3K]

Answer:

linear. Each week adds another 10 dollars.

Step-by-step explanation:

Total = 340 +  10*w

w is the weekly amount

Suppose 5 weeks pass

Then the total amount in her bank account is

Total = 340 + 10*5

Total = 340 + 50

Total = 390

The equation is Linear.
