Your right on both of your answers to number 1 and 2
4x+1 = 2x+23
4x = 2x+22
2x = 22
x = 22/2 = 11
x = 11
3x-8 = 3(11)-8 = 33-8 = 25
BC=25
Answer:
it is 6!/8!
because you take the first and second place you take it as a whole team, and divided by all the cases
the student is wrong because the Constant coefficient is 5 not 3.
constant coefficient is that which have no variable but in the opinion of the student the coefficient is 3 which have a variable x.
so the student is wrong.
Answer:
- x = 18
- 45°
Step-by-step explanation:
First part:
- Write out an equation to represent the image: 2x + 3x = 90
- Combine like terms: 5x = 90
- Divide each side by 5 to cancel out the 5 next to x. It should now look like this: x = 18
Second part:
- 90 ÷ 2 = 45°
I hope this helps!
