Answer:
Step-by-step explanation:
you have two supplementary angles,
both added up=180
7y+5y=12y
12y=180y=15
angle DBC=7y=15*7=105
Answer:
8 boxes approx
Step-by-step explanation:
Step one:
given data
One box contains 48 bars
Required
The number of boxes needed for a total of 338 students if each person is to get at least one bar.
Step two:
this can be gotten by dividing 338 by the number of the bar in a box
= 338/48
=7.04
=8 boxes approx
He needs to purchase at least 8 box
Answer: There is linear relationship between the number of days that Kyla exercise in the total minutes that she exercises.
The independent variable is 'd' and m is the dependent variable which depends on the number of days she exercise.
The linear equation for the situation is given by

Step-by-step explanation:
Let d be the number of days that Kyla exercises, and let m represent the total numbers of minutes she exercise.
Kyla spends 60 Minutes of each day exercising which is constant .
Then the total numbers of minutes she exercise(m) in d days is given by
which is the linear equation.
The relationship between the number of days that Kyla exercise in the total minutes that she exercises is linear, where d is the independent variable, and m is the dependent variable which depends on the number of days she exercise.
[ad d increases m increases by rate of 60 minutes per day]
The linear equation for the situation is given by

Answer:
The two numbers are 2928 and 1878
Step-by-step explanation:
Given this information, we can set up two equations:
x + y = 4806
x - y = 1050
We can solve these simultaneous equations by elimination, which means we can either add or subtract the two equations to solve one of the variables.
In this case, adding the equations together will eliminate y so we can solve for x (remember that y + - y is the same as y - y):
x + y = 4806
+ x - y = 1050
____________
2x = 5856
This can then be simplified to x = 2928 (by dividing by 2)
Now we know x, we can substitute this value into any equation to find y:
2928 + y = 4806 so y = 4806 - 2928 which is 1878.
The two numbers are 2928 and 1878.
Hope this helps!
