Answer:
10
Step-by-step explanation:
2000/ 2x = 10
Multiply each side by 2x
2000/ 2x = 10 *2x
2000 = 20x
Divide by 20
2000/20 = 20x/20
100 = x
Take the square root of each side
sqrt(100) = sqrt(x)
10 = sqrt(x)
Answer:
No solution
Step-by-step explanation:
The question is unsolvable so theres no solution.
3(x+2)+4(3+x)-3=7x
3x + 6 + 12 + 4x -3 = 7x
7x + 15 = 7x
7x - 7x + 15 = 7x - 7x
15 = 0
commutative for addition
<span>22+(m+8)=(m+8)+22</span> then associative
<span>(m+8)+22=m+(8+22)</span>
<span>=m+30</span>
Answer:
39
Step-by-step explanation:
Let's first take the ones with numerical values into play. If you add the second and the third equations, you get 10 = 2(shoe), so the shoe is 5. Then the helmet is 4. Taking the first equation, shirt-5=4+4, so shirt = 8+5=13. Then, we have Goal post = 4+13=17. The question mark is 13+9+17=39.
