Answer:
y= 1 1/2
Step-by-step explanation:
We have to draw the model for 42 divide 7 . In order to draw the model we use below steps.
- Draw 7 boxes to represent 7 groups.
- Assume 42 as the number which represents the total of these 7 groups.
- Put a question mark at the first box.
Attached is the model to represents 42 divide 7 .
In the question mark we should put 6. Hence, when we add 6 to 7 times that will be equal to 42.
Answer:
$6,100
Step-by-step explanation:
So to solve this problem, let's give the amount of money the variable "x". We just need to do x - 0.043 × x. Then we replace x with our answer and repeat the process 13 more times.
42y + 19y would equal 61y
:)
You will need 2 equations, since there are 2 variables (hours worked by George and the ones of Dorothy), let's say x and y respectively
We know
x+y=48 (since they work 48 hours together) and
12x+11.25y=555 (since the sum of their respective hours multiplied by their salary gives a total of 555$)
To solve that, you can isolate either one of the variables and replace it in the second formula, for example:
x+y=48, therefore x=(48-y)
<span>Substitute x in 12x+11.25y=555 and solve for y (to find Dorothy's hours)
</span><span>12(48-y)+11.25y=555
</span>576-12y+11.25y=555
21=0.75y
y=28
