Answer:2,7,12,19
Step-by-step explanation:
a2=a2-1+5=-3+5=2
a3=a3-1+5=a2+5=2+5=7
a4=a3+5=12 and continue so on
7.4x-9.2=2.6+5.2
Simplify
7.4x-9.2=7.9
add 9.2 to both sides
7.4x=17.1
divide both sides by 7.4
x=<span>2.31081081081 (about)</span>
<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%.
