For (11, 1): (11 + 3)1 = 14(1) = 14
For (5, 2): (5 + 3)2 = 8(2) = 16 ≠ 14
For (7, 2): (7 + 3)2 = 10(2) = 20 ≠ 14
For (3, 2): (3 + 3)2 = 6(2) = 12 ≠ 14
Therefore, (11, 1) is a solution to this equation.
Any value of x makes this equation true or all real numbers
-2(3x+12) is the same this as -6x-24 when distributed
so it's -6x-24=-24-6x
her -6x just disappeared so she is wrong :)
Answer:
28/3
Step-by-step explanation:
We see that the triangles are simalar to eachother, so we can set up this ratio:
x/(8+x) = 7/13
x = 56/13 + 7x/13
13x = 56 + 7x
6x = 56
x=56/6=28/3
27 divided by 5 = 5.4 so if you round up you get 6. She’ll need to buy 6 cakes for everyone to have a piece of cake
