All the equations can be graphed and solved by graphing. They can also be solved using various other methods
Answer:
x=7
Step-by-step explanation:
x/3 + x/6 = 7/2
Multiply each side by 6 to clear the fractions
6(x/3 + x/6) = 7/2 *6
Distribute
2x +x = 21
Combine like terms
3x = 21
Divide by 3
3x/3 = 21/3
x = 7
Answer:
1.8
Step-by-step explanation:
-2 1/4 x -4/5 = 9/5
= 1 4/5
= 1.8
You do this by creating an equation with the expressions you've been given, and then solving:
3x - 14 + x + 90 = 180
4x - 14 + 90 = 180
- 90
4x - 14 = 90
+ 14
4x = 104
÷ 4
x = 26
Then you substitute 26 into (3x - 14):
3(× 26) - 14 = 78 - 14 = 64
So your answer is 64°
The least value would be -10 and the greatest would be -2. How I know is because on the negative side the number closer to zero is bigger and he farther is less.
