30% Bc there are 30 boys and 90 girls or it’s 10% boys
Answer:
X = 
Step-by-step explanation:
2 (4-8x) + 6 = 1
Multiply parentheses by 2
8 - 16x + 6 = 1
add (8 + 6)
14 - 16x = 1
Move constant to right and change its sign
-16x = 1 -14
Calcualte te difference
-16x = -13
divide bot sides by -16
x =
Answer:your question seems incomplete but if you looking to find the resulting equation to solve for temperature at a particular time you can use this 28t^2
Step-by-step explanation:
F'(t) = 7(0.8)t
Integrating the RHS
Temp= integral of f'(t)= 28t^2
Therefore, T(°c)= 28t^2
Answer:
Step-by-step explanation:
The first thing you need to do is develop the equation. Less in this case means subtract.
On the left side you have
9 times a number which is 9*x
5 less than 9 times a number means 9x - 5
Now you shift to the right
x = 3
x + 19 What you get is
9x - 5 = x + 19 Subtract x from both sides of the equation
9x - x - 5 = 19 Combine both x terms on the left
8x - 5 = 19 Add 5 to both sides.
8x - 5 + 5 = 19 + 5 Combine terms
8x = 24 Divide by 8
x = 24/8
x = 3
