y = mx + b
m = slope
m = 5
Marco does 70 extra math problems each week. 14(5)=70
2[(9 - 5)^5/8] = 2[4^5/8] = 2[1024/8] = 2[128] = 256
Answer:
Step-by-step explanation:
144(perimeter) divided by 4(amount of sides)= 36
the length of side cd is 36.
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
