Answer:
8x+6
Step-by-step explanation:
To simplify it, the first thing you want to do is distribute the three.
So
3(x+2) = 3x+6,
So we can then add the 5x to it.
3x+6+5x
Then, Combine Like Terms
8x+6
She burns 250 by herself and she burns 3 times as many with her sister.
Multiply the calories by herself by 3:
250 x 3 = 750
Now you need to multiply that by the number of hours.
The formula is a. t[c(h)] = 750h
Answer:
the things wont load whats the question?
Step-by-step explanation:
Let, S = Shirt, J = Jeans
14a)
This question asks for the discount to be added after everything else.
S= 12 J=19
3S + 2J -3 = Cost with discount applied to total
^ This expression adds to costs, then takes away the $3 discount as the end.
14b)
This questions says the discount is added on every shirt, we get a similar expression:
3(S-3) + 2(J-3) = Cost with discount applied on every shirt and jeans
14c)
The difference between a) and b) is that:
> the discount in a) is applied on the total, meaning a lower discount
> the discount for b) is applied on each shirt and jeans, meaning a greater discount
14d)
If I were the shop owner I would be more specific of what the discount included, for example we don't know whether to discount each product (shirts and jeans) or only discount the total.
Answer:
-9/7
Step-by-step explanation:
Put the equation into y = mx + b form, by first isolating y:
9x + 7y= 7
7y = -9x + 7
Divide each side by 7:
y = -9/7x + 1
So, -9/7 is the slope.
