Well the ratio is 16:20 which it 16/20. We can simplify that to 4/5. Therefore the ratio from pink stripes to green stripes will be 4:5
3/4(x) + 5 - 1/2(x) = 3
If x = -8 then,
3/4(-8) + 5 - 1/2(-8)
-6 + 5 - (-4)
-6 + 9
3 = 3
Your answer would be that x = -8
You're welcome.

Answer:
1.you use a "carrot" it looks like this ^ so you put 6^3 an that is saying 6 to the power of 3
2. you can also use the symbols option and there is shows little numbers but only gives you the option for the power of 2 and 3
example: 6³
3. click equation option and put the x^2 and then delete the x and put the number or variable and then within the brackets put what the power should be.

Answer:
Number of vines that should be planted are 150.
Step-by-step explanation:
The number of pounds of pounds of grapes produced per acre is represented by the expression 
Where n = additional vines planted
To maximize the production of grapes we will find the derivative of A(n) and equate it to zero.
For 
3 - 0.02n = 0
0.02n = 3
n = 
n = 150
To check whether the maximum value of the function is at n = 150, we will find the second derivative A(n).
Which shows A"(n) < 0
Therefore, A(n) has the maximum value at n = 150.
Therefore, number of vines that should be planted are 150.
Answer:
37.2
Step-by-step explanation:
when you turn the small triangle LMN to its right angle to cover the right angle of KLM, you find that they are similar triangles.
therefore the corresponding side lengths are at the same ratio.
LM/KM = MN/LN
LM = 24
MN = 13
we can get LN via Pythagoras of the small triangle
LN² + MN² = LM²
LN² + 13² = 24²
LN² = 24² - 13² = 576 - 169 = 407
LN = sqrt(407) = 20.174241
now back to our main problem
24/KM = 13/sqrt(407)
24×sqrt(407)/13 = KM = 37.2
