Call the numbers x and y. According to the first sentence, x + y = 67. According to the second sentence, x = y + 5. You can combine these two equations to find the values of these variables:
x + y = 67
(y + 5) + y= 67
2y = 62
y = 31
You can use this to find x by plugging in y to either original equation:
x = y + 5
x = 31 + 5
x = 36
Answer:
Two
Step-by-step explanation:
If you have one and added one you have two
Answer: 90 degrees
============================
Explanation:
Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.
Consequently, we can replace y with x and solve for x like so:
x+y = 180
x+x = 180 .... y is replaced with x since y = x
2x = 180
2x/2 = 180/2
x = 90
This means y = 90 as well. As a check, note how
x+y = 90+90 = 180
which verifies our answer.
Answer:
<h3>5 and -5</h3>
Step-by-step explanation:
For a number line the centre of the line is the origin (0, 0). To get the two numbers that are a distance of 5 from 0, we will add 5 to 0 and subtract 5 from 0.
Towards the positive x axis;
The value at a distance of 5 from 0 = 5- 0 = 5
Towards the negative x axis;
The value at a distance of 5 from 0 = -5- 0 = -5
Hence the two values on a number line that are a distance of 5 from 0 are 5 and -5
