Since it’s 2x+1=23 if you were to put x as 22 then add the 1 to it, it would equal 23, So the answer is 22.
<span>We have 75 mL of 4% sugar solution.
We have to add a 30% sugar </span><span>solution to make a 50% </span><span>sugar solution.
75 * .04 + .30x = .50 * (75 +x)
3 + .30x = 37.5 +.50x
I can't get the equation to solve.
Did you type it correctly? For one thing, you have the percentages typed as .30 % and 4%. Are the decimal places in the correct positions?
Also, no matter how much 30% sugar solution you add, it will NEVER increase to 50%.

The answer is 9. Solve the 4•3 first which is 12. Then, do as per normal. 12+12-15= 9.
It is -2, because looking at it the u point is on the line of -2
The greatest common factor is 8 because it can divide both of them without remainder
