Answer: Im pretty sure its x = 4.472135955

Step-by-step explanation:

DISCLAIMER: I may be wrong I am kind of rusty.

You got to use the Pythagorean theorem (a^2 + b^2 = c^2) to answer this.

First you label your triangle by putting the hypotenuse as "c" the other known value as "b" and the unknown value as "a".

Now you input the answers into the equation.

x^2 + 4^2 = 6^2

Now answer the known values.

x^2 + 16 = 36

Now subtract by 16 to get rid of the sixteen.

x^2 + 16 -16 = 36 -16

x^2 = 20

Now to get rid off the ^2 find the square root.

x = 4.472135955

Carlos has scored 83, 81, and 73 on his previous three tests. What score does he need on his next test so that his average (mean

disa [49]

Answer:

Step-by-step explanation:

let x be his mark in the fourth test, then

mean = $\frac{83+81+73+x}{4}$ = 83 ( multiply both sides by 4 )

83 + 81 + 73 + x = 332

237 + x = 332 ( subtract 237 from both sides )

x = 95

Without drawing the graphs, find the points of intersection of the lines: a 7x+4y=23 and 8x–10y=19

emmainna [20.7K]

Answer:

(3,0.5)

Step-by-step explanation:

The given system has equations:

$7x + 4y = 23 \\ 8x - 10y = 19$

Let us multiply the second equation by 4 and the first equation by 10.

$70x + 40y = 230 \\ 32x - 40y = 76$

We add both new equations to get:

$102x = 306 \\ x = \frac{306}{102} = 3$

Put x=3 into the first equation and solve for y.

$7(3) + 4y = 23 \\ 21 + 4y = 23 \\ 4y = 23 - 21 \\ 4y = 2 \\ y = \frac{1}{2}$

The point of intersection is the solution to the system of equation which is (3,0.5)
