Answer:
m + 10 = 39
Step-by-step explanation:
In 10 years she will be 39, so you will add 10 to her age right now, which is m, so m + 10 = 39
Answer:
Step-by-step explanation:
it is 1.5 take it like that
Answer:
n=4
Step-by-step explanation:
To get an undefined slope, the denominator has to be zero
m= (y2-y1)/ (x2-x1)
This means that x2-x1 = 0
or x2=x1
So 4=n
Answer:
95.49 g
Step-by-step explanation:
D = m/v
Looking for mass so isolate m to form equation format
D × V = m
Plug in numbers
.7892g/mL × 121.0 mL = 95.4932 g
Only g and not g/mL because the mL cancels each other out. It's easier to see if you rewrite it on paper.
Round to sig figs
Both original numbers hold 4 sig figs
95.49 g
Answer: Each ticket costs $32
=========================================================
Explanation:
Let x be the cost of one ticket. If four people buy a ticket each, then they collectively spend a total of 4x dollars for those tickets. Add on 4*3 = 12 dollars from the fact that they bought the ice cream, and we arrive at the expression 4x+12. This is the total amount spent in dollars for the tickets and ice cream combined.
Set this expression equal to 140 and solve for x
4x+12 = 140
4x = 140-12
4x = 128
x = 128/4
x = 32
This says that each ticket costs $32
If one ticket costs $32, then four of them cost a total of 4*32 = 128 dollars. Add on the $12 spent on the ice cream to get 128+12 = 140, which helps verify we have the correct ticket price.
Another way to verify is to replace x with 32 in the original equation we set up, then simplify like so
4x+12 = 140
4*32+12 = 140
128+12 = 140
140 = 140
This is very similar to the previous verification technique used earlier.
