together Preston and Horatio have 49 video game Horatio has 11 more games than Preston how many games does each person have
Bingel [31]
Preston has 19 games and Horatio has 30 games.
You can set this as a system of equations, set Preston as x and Horatio as y.
Both of the amounts add up to 49, so we can get the equation:
x+y=49

Since Horatio has 11 more games, we can get the equation:
y-x=11

If we add the x to the other side, the second equation becomes: 
y=x+11

We can plug in the second equation into the first and get the equation:
x+11+x=49

with a little simplification, we get x (Preston) is equal to 19. If we add 11 to it, we get Horatio's amount: 30

How to solve for x 15 + 8x = 45 + 6x
Reil [10]

Answer:

15

Step-by-step explanation:

Let's solve your equation step-by-step.

15+8x=45+6x

Step 1: Simplify both sides of the equation.

8x+15=6x+45

Step 2: Subtract 6x from both sides.

8x+15−6x=6x+45−6x

2x+15=45

Step 3: Subtract 15 from both sides.

2x+15−15=45−15

2x=30

Step 4: Divide both sides by 2.

2x

=

30

What is the value of x in the triangle?
Blizzard [7]

Answer:

x = 23.78

Step-by-step explanation:

From the information given, we can construct the triangle shown in the attached picture.

With respect to the angle 18, we have the hypotenuse (25) and we want to know the adjacent side (x). Thus, what trigonometric ratio relates adjacent to hypotenuse? COSINE! Thus we can set-up the ratio shown below and compute x.

Cos (18)=\frac{x}{25}\\x=25*Cos(18)\\=23.78
