Answer:
11 + x + 19*x
Step-by-step explanation:
The sum of eleven, a number, and the product of nineteen and the number.
we have to read carefully and understand how to interpret
when he says the sum of separates into 3 parts because there is a "comma" and an "and"
Now let's separate the 3 parts of the sum
1 part
says eleven so we just put 11
eleven = 11
2 part
in the text it says that we replace "a number" with x
a number = x
3 part
In this case we simply make the product between the given values
the product of nineteen and the number
19 * x
Now we can accommodate everything and we finish
11 + x + 19*x
Answer:
y = 9x
Step-by-step explanation:
You can set up linear equations like this: y = mx + b, where m is the slope or rate, and b is the y-intercept.
9 would be the slope, since he has to pay $9 per gift.
The y-intercept is when x = 0, but if he doesn't buy any gifts, he won't have to pay anything, so b = 0. You don't have to include it since it's 0.
So, it's just y = 9x
Hope that helps! :D
