Answer:
x = 23
y = 128
Step-by-step explanation:
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.
98 = 2x + 3x - 17
115 = 5x
x = 23
Angles 3x - 17 and y form a linear pair, so they are supplementary.
3x - 17 + y = 180
3(23) - 17 + y = 180
69 - 17 + y = 180
52 + y = 180
y = 128
Answer:
- linear equation
- all variables are to the first power
Step-by-step explanation:
"Linear equation" is another way to say "first-degree equation." That is, the equation involves constants and variables to the first degree only. No term contains any product or ratio of variables.
A term is first degree when the sum of all of the exponents of the variables is 1, and all exponents are positive integers. That is, the only allowed exponent of the single variable in a term is 1.
Here, the term on the left side of the equal sign has x to the first power. The term on the right side of the equal sign has y to the first power. Both are linear terms, so this is a linear equation.
Answer:
first choice: y≥1/3 x+3 and 3x-y>2

Answer:
Step-by-step explanation:
Answer:
x = 20
Step-by-step explanation:
I don't see a y in the diagram.
The 3 angles x, 90 and (4x - 10) lie on the line EF and sum to 180°, so
x + 90 + 4x - 10 = 180, that is
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
