The cost of 1 vanilla ice cream and 1 strawberry ice cream should total to $31. Since you only bought one of each flavor, you simply have to add their unit prices. 

Cost for 1 carton of strawberry ice cream + Cost for 1 carton of vanilla ice cream = Total Cost
Total Cost = s + v  --> this is the general equation

Since s = 1.5 + v, the modified equation would be
Total Cost = 1.5 + v + v
Total Cost = 1.5 + 2v

If the revenue for the week is $2000 and the labor cost consists of two workers earning eight dollars per hour who work 40 hours
arsen [322]
To find the cost of labor for one worker, you multiply the wage by the number of hours worked. 

40 * 8 = 320

Because there are two workers, now you double it. 

320 * 2 = 640

To find the percentage of the revenue that this is, you do the labor cost divided by the revenue. 

640 / 2000 = 0.32

Move the decimal two places to the right to get the percentage. 

0.32 = 32%

The labor cost is 32% of the revenue.

Identify the slope and y-intercept of 3/5 - 1/3 x
Rudiy27
Your 3/5 - (1/3)x is an expression, not an equation.  You must write out the entire equation in question:

"Identify the slope and y-int. of y = 3/5 - (1/3)x."

The y-intercept is obvious:  It's 3/5.

The slope is (1/3).

Triangle STU has reflected over line m to form Triangle S'T'U'. What is the value of y?
Lera25 [3.4K]

Answer:

  D.  5

Step-by-step explanation:

The congruence of S'T' with ST tells you ...

  9 = x +7

  2 = x

The congruence of S'U' and SU tells you ...

  4x = y +3

  4·2 -3 = y = 5 . . . . substitute the value of x; subtract 3
