Assume the number is x
now, we will translate the written english into equation:
seven minus 2 times the number is 7-2x
the number minus 2 is x-2
we will equate these two equations (the question says that they are equal) ans solve for x as follows:
7-2x=x-2
7+2=x+2x
9=3x
x=3
the required number is 3
Answer:
Step-by-step explanation:
a.18/-3 = (-6)
b. -5/-1 = 5
c. 24/-6 = (-4)
d. -10/-1 = 10
e. -25/5 =(-5)
f. 8/-2 = (-4)
In multiplication and division, if there are are odd number of negative signs, the result will have negative sign.
If there are even number of negative signs, the the result will have positive sign
Hello
This is a right angle as you can see by the small square at the bottom. So this means that it is 90 degrees.
Because we already know part of the 90 degrees, we can do 90-50 degree which leave us with 40 degrees.
So as we look at 8x, it needs to equal 40
- 8x=40 divide both sides by 8
- x=5
Hope this helps!

the diagonal squared = base squared + altitude squared.
