Answer:

82%

Total number of questions = 150

Questions not answered = 27

questions answered = 150 - 27 = 123

percent questions answered

A. Find value of x and KL if K is between J and L.
MrRa [10]

Answer:

x=3

Step-by-step explanation:

If k is between J and L, then

JK + KL = JL

2x+11 + (3x) = 13x-13

Combine like terms

5x +11 = 13x -13

Subtract 5x from each side

5x-5x+11 = 13x-5x-13

11 = 8x-13

Add 13 to each side

11+13 = 8x-13+13

24 = 8x

Divide by 8

24/8 = 8x/8

3 =x

What is the factorization of 3x2 – 8x + 5?
Tanzania [10]

Answer:

(x-1)(3x-5)

Step-by-step explanation:

Factorize means convert and expression into multiple factors.

You have to find to factor that multiplied equals the original equation. Firts of all you split the expression of  square X into 3X an X, so you  guarantee that when you multiply 3X by X, the result is 3X^2.

After doing that, you need to think in numbers that equals the middle term (8X) and the constant (5).

-1 and -5 guarantee you that the multiplication of them results into +5, so you start with those numbers. Then you have to find where to put them in order to find the -8X.

-5 x X = -5X

-1 x 3X = -3X

And adding those two expresion you find the -8X that you need!

Please try to solve it multiplying term by term and check the final equation.

Seperate the number 53 into 3 parts so that the second number is 3 less than the first number and the third number is twice the
irga5000 [103]
Hello,

Let a the first, b the second and c the third.
a+b+c=53
b=a/3
c=2a
==>a+a/3+2a=53
==>10a/3=53
==>a=15.9
c=2*a=2*15.9=31.8
b=a/3=15.9/3=5.3

Proof: a+b+c=15.9+5.3+31.8=53

The second number is 5.3
