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
Answer:
K=13
Step-by-step explanation:
So first, we subtract 13 with 3/4 (That comes from 4 3/4) and we get 12 1/4.
And then, we subtract 12 1/4 with 4, and we get 8 1/4

The first one x is greater than and equal to 34
Answer:
3(2x+2) = 6x + 6
Step-by-step explanation:
Those are algebra tiles, so it is saying (if you read across the top) 2x +2 then if you read down you have 3 units, so the dot means 2x + 2 multiplied by 3
If you write it in algebraic terms it is 3(2x+2) so the answer when you distribute is 3 (2x) + 3(2) so 6x + 6, and if you count the number of red rectangles you have 6 of them, hence the 6x, and if you cound the units in gray you have 6 of them, hence the 6.
Algebra tiles are used to demonstrate algebra concepts
