Answer:
She did everything correctly, therefore J
Step-by-step explanation:
6x-3+8+2(3+4x) doing distributed property gives you 6x-3+8+6+8x, step 3 you organize like terms. 14x-3+8+6 Step 4, you subtract 3 therefore in step 5 giving you 14x+11!
So it should be y = 2*2^x
Where x is the time and y is the final width after x minutes
Answer:
16
Step-by-step explanation:
Let's denote:
a: number of students wearing sneakers
b: number of students wearing boots
We have:
a + b = 36
a/b = 4/5 (multiply both sides by b => a = 4b/5)
Substitute a = 4b/5 into a + b = 36
=> 4b/5 + b = 36
=> 4b/5 + 5b/5 = 36
=> 9b/5 = 36
=> b/5 = 4
=> b = 20
=> a = 4b/5 = 4(20)/5 = 16
IF EC = 8, than we know for sure that the length of AC would be 2 x 8 = 16
The formula to use in determining Rhombus area is
A = (AC . DB)/2 , so the value x could be found with this equation :
72 = 16 (x-1) / 2
72 = (16x -16) /2
72 = 8x - 8
80 = 8x
x = 10
