Answer:
You need to simplify 0.3(12x + -16) = 0.4(12 + -3x)
Step-by-step explanation:
Reorder the terms:
0.3(-16 + 12x) = 0.4(12 + -3x) (-16 * 0.3 + 12x * 0.3) = 0.4(12 + -3x) (-4.8 + 3.6x) = 0.4(12 + -3x) -4.8 + 3.6x = (12 * 0.4 + -3x * 0.4) -4.8 + 3.6x = (4.8 + -1.2x)
Solving -4.8 + 3.6x = 4.8 + -1.2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.2x' to each side of the equation. -4.8 + 3.6x + 1.2x = 4.8 + -1.2x + 1.2x
Combine like terms: 3.6x + 1.2x = 4.8x -4.8 + 4.8x = 4.8 + -1.2x + 1.2x
Combine like terms: -1.2x + 1.2x = 0.0 -4.8 + 4.8x = 4.8 + 0.0 -4.8 + 4.8x = 4.8 Add '4.8' to each side of the equation. -4.8 + 4.8 + 4.8x = 4.8 + 4.8
Combine like terms: -4.8 + 4.8 = 0.0 0.0 + 4.8x = 4.8 + 4.8 4.8x = 4.8 + 4.8
Combine like terms: 4.8 + 4.8 = 9.6 4.8x = 9.6 Divide each side by '4.8'. x = 2
Simplifying x = 2
Let
x--------> the number
we know that
x+(1/x)=65/28---------> x+1/x=65/28-----> multiply by x
x²+1=65/28*x-----> x²-(65/28)*x+1=0
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
x=1.75-----> 1 3/4----> (4*1+3)//4----> 7/4
so
7/4+4/7----> (7*7+4*4)/28----> (49+16)/28----> 65/28----> is correct
the answer isthe number is 7/4
Answer:
9. B: y = 7.5x - 2
10. y = 2x - 1/4
11. C: A newborn baby weighs 8 pounds at birth and gains 1.5 pounds for 3 months.
Step-by-step explanation:
If there is a minus symbol before the y-intercept then the slope is negative.
For 0 it has 8. A newborn baby is 0 months old.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
