Answer:
$1.40
Step-by-step explanation:
Divide 4.20 by 3.
<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%.

Answer:
Step-by-step explanation:
<u>Corresponding side have same ratio:</u>
- 55/121 = 5/11 (divide by 11)
- 40/88 = 5/11 (divide by 8)
- 30/66 = 5/11 (divide by 6)
The similarity ratio or the scale factor of the larger triangle to the smaller is 5/11
Answer:
(5.5,-8)
Step-by-step explanation:
(7 + 4)/2 = 5.5
(-6 + -10)/2 = -8
