Answer:
step 1: x+50+4x=90
the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.
step 2: x+50+4x=90
x+4x=50
5x=50
x=10
then you solve the equation, x is 10
If the input value is negative, the output value is always positive. We know this because the negative sign before the 4z will always reverse the negativity of the number that is plugged in.
Answer:
1. Because it is an integer.
2. Because it is a terminating decimals.
3. Because it is a terminating decimal as well as an integer.
4.Because it is a natural number.
5.Because it is a terminating decimal when divided.
6. Because it is a whole number.
7. Because it is a natural number.
8. Because it is a terminating negative decimal when divided(simplified basically).
Step-by-step explanation:
Irrational numbers include:
Non terminating,and non recurring decimals.
Example: 1.2345677854903421......so on.
Hope this helps... :-)
80-3x=56, Subtract 80 from each side:
-3x = 56-80
-3x=-24
x will equal 8, hope this helps! Have a BLESSED day! :-)
