Answer:
Number = 2
Step-by-step explanation:
Let the number be <em>x</em>.
According to the question,
- Number increased by 11 = x+11
- Multiplied by 2 is 26 : (x+11)*2 = 26
Equation will be,
Solving for x,
- 2x+22 = 26
- 2x = 26-22
- 2x = 4
- x = 4/2
- x = 2
Thus,the number is 2.
Answer:
0
Step-by-step explanation:
e(2)=0
Anything times 0 = 0, we know that x is 2 so E has to be 0.
Each student should do 1/4 of one board or 1/8 of both boards. This is because 8÷2 is 4, which means 4 people need to work together on one board.
Answer:
a=-4
Step-by-step explanation:
1) Isolate x for 2x+y=3 which will give us x=3-y/2
2) Substitute 3-y/2 in the equation -8x+ay=-11
3) Then we simplify
4) Isolate for y
5)Then we simplify in order to get -4
