Answer:
x = 10
I used the Interior Angles of a Triangle Rule --The sum of all 3 interior angles in a triangle is always 180°.
(3x + 28) + (5x - 18) + 90° = 180°
Now i can get rid of the parentheses and combine like terms.
3x + 5x + 28 - 18 + 90 = 180
8x + 10 + 90 = 180
8x + 100 = 180
Then i subtract 100 from both sides to isolate x.
8x + 100 - 100 = 180 - 100
8x = 80
Then, i divide both sides by 8 to find x.
8x ÷ 8 = 80 ÷ 8
x = 10
Mode, because out of the 3 numbers, it is the least. BTW- the only reason I know this is because I had this question not too long ago
Answer:
No.
Step-by-step explanation:
the system of equations provided in the condition consists of two linear equations in slope-interception form. The slope of the 1st equation is equal to the slope of 2d equation. It means, the lines are parallel. In other words, no solution of this system, they are not correct.
Answer: no.
Answer:
3/8
Step-by-step explanation:
With unlike denominators find the Least Common Denominator (LCD)
LCD = 8
Multiplying numerators and denominators to get the LCD in all fraction denominators
=3/4 times 2/2−3/8
Then rewriting the equation with the equivalent fractions
=6/8−3/8
With like denominators we can operate on just the numerators
=6−3/8
=3/8
