Hi there!
Here are all the steps into simplifying this expression :
<u>(4 × 2)</u> + 15x + 49
Do the multiplication first → 4 × 2 = 8
<u>8</u> + 15x + <u>49</u>
Add the similar terms together → 8 + 49 = 57
15x + 57
Since there are no longer similar terms, the expression can not be simplified anymore and you are left with this expression as an answer :
15x + 57
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
B. Jenny paid $322 for 23 T-shirts, which is a rate of $14 per T-shirt.
Step-by-step explanation:
To find the rate per shirt, divide the cost by the number of shirts:
322/14
= 14
So, she paid $322 at a rate of $14 per shirt.
Therefore, B is correct.
They say that 2 inches on the map equals 25 miles in real life.
That means that 1 inch on the map equals how many miles in real life?
... [time for you to think] ...
That's 12.5 miles. (simply 25 / 2 = 12.5).
So one inch on the map is equal to 12.5 miles in real life.
Starting from this....
So 1 inch on the map is equal to 12.5 miles in real life.
So 2 inches on the map is equal to 25 miles in real life. (2x12.5)
So 3 inches on the map is equal to 37.5 miles in real life. (3x12.5)
So 4 inches on the map is equal to 50 miles in real life. (4x12.5)
So 19.2 inches on the map is equal to <....> miles in real life (19.2 x 12.5).
For you to fill in the <...> using the steps I gave you.
Answer:
60 hours
Step-by-step explanation:
Let X be the total capacity.
Inlet speed: X/15
Outlet speed: X/20
Combined:
X/15 - X/20 = X/60
X/60 = X/time
Time = 60 hours
X^2 2x + 1 = (x + 1)^2
x is replaced by x + 1
the translation is 1 unit to the left
