No, Tyson's final expression is not equivalent to the initial expression.
<h3>Fraction addition;</h3>
According to Tyson's evaluation after collecting like terms; we have;
- 1/5g +(-1g) + 1(3/10g) + (-1/10) + (-1/10)
open parenthesis
- 1/5g - 1g + 3/10g - 1/10 - 1/10
Upon addition of like terms; we have;
Hence, the correct expression is; (-1/2)g -1/5

Answer:
Well to solve this I’m gonna use substitution
So
2x-3y=-14
5x+9y=14
I‘m gonna isolate ”x” on the first equation
So it’ll be
2x-3y=-14
2x=-14+3y
x=-7+1.5y
X is -7+1.5y
Now you can subsitute into other equations to find what Y is worth
So lets use the second equation
5(-1+1.5y) + 9y = 14
Now solve for y which is -2
If you subsitute Y back in an equation you’d get -4 for x
So y = -2
and X= -4
Answer:
The second choice, 50x + 150y
<h3>Answer: 71</h3>
==================================
Explanation:
Multiply the values in the second and third columns. Do this row by row.
Row1: 50*55 = 2750
Row2: 75*32 = 2400
Row3: 150*13 = 1950
Add up the products to get 2750+2400+1950 = 7100
Then divide this by the total frequency 55+32+13 = 100 to get 7100/100 = 71
Yeah I was just going to put that there
