Answer:
<h3>(5y-3)/2</h3>
Step-by-step explanation:
Given the equation 2x+ 3 / 5= y
Cross multiply
2x+3 = 5 * y
2x+3 = 5y
Subtract 3 from both sides
2x+3-3 = 5y - 3
2x = 5y-3
Divide both sides by 2
2x/2 = (5y-3)/2
x = (5y-3)/2
Hence the value of x is (5y-3)/2
Answer:
x = 22, and im rlly sry, i dont know how to solve for y...im sry...
Step-by-step explanation:
180 - 55 = 125 degrees
so
6x - 7 = 125
<u> +7 +7</u>
6x = 132
divide by 6
<u>x = 22</u>
Answer:
180° - 110° = 70°. 70° represents the other two angles, so it needs to be divided in 2 to get the answer of 35°.

Answer:
3k^2 -k+5
reason:
when adding two equations together, you combine like terms.
First, add -2 to 7 to get 5
Then, add k, or 1k, to -2k, which gives you -1k, or just -k
3k^2 stays the same because there are no like terms in the other equation to combine it with
Step-by-step explanation:
let the total students be x then
25/100x=9
x=9×100/25
x=9×4
x=36
so total students are 36
