Answer:
9 OR 1
Step-by-step explanation:
Let the number be x
x² - 10x = -9
x² - 10x + 9=0
a=1
b=-10
c=9
Solve using the quadratic formula
x =9 or 1
First try to isolate the variable, in this case "y". the first step to this is add 5/6 to both sides to get 5y/42=5/6. next multiply each side by 42 to get 5y=35. next divide by 5 to get y=7. so y=7 is the answer.
Answer:
17x and 3x
Step-by-step explanation:
like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.
An obtuse triangle is a triangle that has an angle greater than 90 degrees, so 1. One angle is greater than 90 degrees is correct.
2/5 divided by 4/7 is equal too 7/10
