Answer:
they sold 210 hot chocolates and 85 coffees
Step-by-step explanation:
We know that they sold $200 worth of drinks
x will be the number of hot chocolates sold
y will be the number of coffees sold
This means that
.75x+.5y=200
We also know that they sold 295 total drinks which means that
x+y=295
This is a system of linear equations which I will solve through substitution
x+y=295
Subtract y from both sides and divide by -1 to get
-x+295=y
Plug y into the first equation and get
.75x+.5(-x+295)=200
Distribute the .5 and simplify to get
.75x-.5x+147.5
.25x+147.5=200
Subtract 147.5 and then divide by .25 to get our x value
x=210
Now we can go back and plug this in into our equation
210+y=295
Subtract 210 to get y
y=85
This means that they sold 210 hot chocolates and 85 coffees
943 pounds when you add them together

nope not correct
Step-by-step explanation:
8x³ is Single term
x³ is the variable and 8 is the coefficient
$328.99 x .20 = $65.79
$328.99 - $65.79 = $263.20
Answer:
Step-by-step explanation:
Let's say that this "certain number" is x. If we are adding that "certain number" to 36, then x+36 equals something. That "certain number," referred to as "it" in the second part, then also must be multiplied by 4 (4x) to get the same result as x+36, therefore:
x+36=4x
-x -x
36=3x
3 3
12=x
Check yourself:
If 12 is added to 36, it equals 48.
If 12 is multiplied by 4, the result is 48 as well.
