Answer:
2.52
Step-by-step explanation:
5x + 15.5 = 28.1
subtract 15.5 from both sides
5x = 12.6
divide both sides by 5
x = 2.52
Answer:
1/4
25%
Step-by-step explanation:
Robert has 1/2 of the candy bar
If he gave his sister half, she has 1/2 x 1/2 = 1/4 of the candy bar
To convert 1/4 to percentage, multiply by 100
1/4 x 100 = 25%
b is an ipotenuse, so b > a and 2a+b>3a
Answer:
y = 0.1x+200
Step-by-step explanation:
First, let's establish that:
x is independent
y is dependent
Basically, the value of y will depend on what x is.
The problem states that the slope of the line is Dave's comission, so since he makes 10% of comission, we can make the slope as 0.1x (mx)
The problem also states that the y intercept (b) is Dave's base salary, and earlier in the problem it states that his base salary is $200 a week. Therefore, b=200
now, the equation is:
y=0.1x+200
