what you do I set 45x equal to your two other angles since the sum of those two angles is equal to that angle outside the triangle.

so you have

45x=57+x+25x

combine like terms

45x=57+26x

then subtract 26x on both sides to get

19x=57

lastly divide by 19

x=3

Factor completely 8y^3+16y^2
gregori [183]

Answer:

8y^2(y + 2)

Step-by-step explanation:

The given expression is 8y^3 + 16y^2

Let's find the greatest common factor of 8y^3 and 16y^2

The GCF is 8y^2. Let's take out the GCF outside and write the remaining terms as follows

8y^2 (y + 2)

Therefore, the factors are 8y^2 and (y + 2)

That is 8y^3 + 16y^2 = 8y^2(y + 2)

Thank you.

Suppose that a customer is purchasing a car. He conducts an experiment in which he puts 10 gallons of gas in the car and drives
True [87]

Answer:

mean = 250.2

mean =  249.4

Step-by-step explanation:

given data

experiment =  15 times

solution

we get here mean that is express as

mean = \frac{\sum x }{n}      ............1

so mean for cart 1 is

mean =  \frac{232+ 268 + 163+ ....+ 289}{15}

mean = 250.2

and

mean for cart 2

mean =  \frac{243+ 257 + 257 + ....+ 265}{15}  

mean =  249.4

Theo made a donation to a charity. His grandfather agreed to add $4.00 to Theo's donation amount and then donate half of that su
miss Akunina [59]

So you have to solve for "donation" - so let's call that X. And the things we know are what the grandfather donated, as a function - meaning based upon - Theo's donation. We'll call that Y.

So Y is equal to 1/2 of $4 plus Theo's donation...... 0.5*(x+4).

So... 4.25 = 0.5(X+4), solving for X

4.25=0.5x + 2

-2            -2

2.25=0.5x - divide each side by 0.5 to get x alone.

x = 4.50

Plugging back in:

(4.50 + 4.00)*0.5 = 4.25!
