Multiply 3 times x which gives you 3x then multiply 3 times -1 which gives you -3. Now you have an equation 3x-3=6. This is a two step equation so you have to add 3 (inverse operation) to 6 which gives you 9. Now you divide 9/3 which equals 3. The answer is 3
The triangle is an isosceles triangle because of its degrees. A triangle consists of 180 degrees therefore, 180-90-45 simply makes it 45 matching the other side.
So we can assume that side b is also equivalent to side a. Here we use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25+25=50
The square root of 50 is 7.1
x= 7.1
Answer:
b x 5 = 30
Step-by-step explanation:
This is one of the many correct answers. The reason why is because it shows that the variable is correct. And if you didn’t know what the variable was you could just divide 30 / 5.
The answer is A
since 2x+3(2x)=16
Hence 8x=16
The slope of line m is also 2/7 because they are parallel so they have the same slope
