For this case, the first thing we must do is define variables:
b: number of boxes
d: cost in dollars
We now write the equation that models the problem.
We have then:
d = 6b
Answer:
an equation for the number of dollars, d, you spend on b boxes is:
d = 6b
The nearest hundred for 3,486 is 3,500 since it would round up because it is closer to that hundred.
Answer:
A. Control group
Step-by-step explanation:
A control group is a group in an experiment or study that does not receive experimental procedure during such that it is then used as a benchmark to measure how the other tested subjects do.
An experimental group is a group in an experiment or study that receives an experimental procedure. The values of gotten from the test are recorded and the effect of independent variables on the dependent variables are determined.
Control experiment can be used to determine whether or not the customers are friendly. Experimental group will be the customers whom the waiter is extra friendly toward. The control group will be the alternate customer whom the waiter is not extra friendly toward.
No, y does not vary directly with x. When y varies with x, it means that y and x always have the same ratio. Simplified, the first ratio is 1:5 and the second and third ratios simplified are 1:6. Therefore, y does not vary with x.
Answer:
easy
Step-by-step explanation:
The equation you wrote has no solutions since the left hand side is equal to 6x-10 and the right hand side is equal to 6x+8
