Answer:
Last one
Step-by-step explanation:
You can simplify the first one or compare both of them if they have the same ratios! Hope this helps <3
Answer:
x = 7
Step-by-step explanation:
The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).
Solving 8x - 36 + 70 + 90 = 180 for x:
8x - 36 = 20, or 8x = 56.
Dividing both sides by 8 yields x = 7.

1 liter=.26 gallons so 20 liters= 20*.26= 5.2 gallons.
You need to use .75 ounces of soda ash per gallon so you must multiply .75 by 5.2.
.75*5.2 = 3.9 ounces
