Answer:
13a-3
Step-by-step explanation:
7a-(4a-8a+3)+2a First, distribute the negative 1.
7a-4a+8a-3+2a Combine like terms.
13a-3
Answer:
The ratio of cranberry to apple to orange juice is 9: 5: 6.
Step-by-step explanation:
In order to compare the amounts of juices in the drink and determine the fraction of juice the is cranberry, we need to first find the lowest common denominator of the first two fractions: 1/4 and 3/10. The lowest common denominator of 4 and 10 is 20. Using a common denominator of 20, 1/4 becomes 5/20 (by multiplying numerator and denominator by 5) and 3/10 becomes 6/20 (by multiplying numerator and denominator by 2). Since we now know that 11/20 of juice is either orange or apple, than 9/20 of the juice must be cranberry for a total of 20/20. When writing a ratio to compare these fractions, we just use the numerator to get 9: 5: 6 or 9parts cranberry to 5 parts apple to 6 parts orange.
If we are using slope intercept form, m =(4-1)/(6-0) = 3/6=1/2
y=1/2*x+1(from (0,1))
y =1/2*4+1
y = 2+1 = 3
Looking at this again, you are given the point (6,4), so you can get 4 from that as well.
Answer:
Step-by-step explanation:
if we tip/tax 6% of 156.67 we will do:
156.67*(6/100)=9.40 this is the amount of tip
156.67+9.40=166.07
100g of ammonia releases 271.18 kJ of heat.
<u>Explanation:</u>
Given:
N₂ reacts with H₂
The reaction is:
2N₂ + 3H₂ → 2NH₃ + 92.2 kJ
According to the balanced reaction:
2 X 17g of ammonia releases 92.2 kJ of heat
34g of ammonia releases 92.2 kJ of heat
100g of ammonia will release = kJ of heat
= 271.18 kJ
Therefore, 100g of ammonia releases 271.18 kJ of heat.
