Answer:
x+y=0 and 3x-2y=10
Step-by-step explanation
Let the numbers be x and y.
The sum of the two numbers is 0
Letting the smaller number be y and the
larger number be x:
twice the smaller number
Also, 3 times the larger number
Now ,twice the smaller number subtracted from 3 times the larger number is 10.
Therefore the equations are
and
Answer:
43 degrees for the first problem
Step-by-step explanation:
On the first problem we see, we are given that one angle is 231 degrees. After counting the sides of this shape, we see it is a 4-sided quadrilateral. This means that the total amount of degrees in this shape equals 360 degrees. Since each unknown degree is represented by the same value (w), we can deduce that all of these unknown angles are equal to each other.
Let's set up our problem now.
360 degrees = the amount of degrees in a quadrilateral
231 degrees = the given amount of degrees we have so far
In order to see how many degrees we have left in the quadrilateral, let's subtract the number degree we already know from the total degree number that we know: 360 - 231 = 129
Now we see that the remaining three angles have a total of 129 degrees. This doesn't mean we're done.
3 congruent angles together = 129 degrees
We need to find the degree of a single unknown angle now. This can be done by simply dividing the mass total of the three congruent angles by the amount of congruent unknown angles there are.
129/3 = 43
Our final answer is 43 degrees.
Answer:
Amount of money paid by each student is equal to 
Step-by-step explanation:
Given: A group of children bought 
presents that cost 
each and a card that cost 
.
To find: amount of money each student paid in terms of 
Solution:
Cost of each present 
Cost of presents 
Cost of a card 
Therefore,
Amount of money paid by each student in terms of = Cost of presents + Cost of a card
Answer:
m= -5
Step-by-step explanation:
This is very simple.
Basically, the formula for a slope intersect form is this:
y= mx+b
Where y is the y value, x is the x value, b is the y intercept, and m is the slope.
Because m is -5 in this equation, that means the slope is -5.
