Answer:
2x + 11 = 25
x = 7
Step-by-step explanation:
Let the number be x.
Double of x and add 11 equals 25.
Solve the equation.
Subtract 11 on both sides.
2x = 25 - 11
2x = 14
Divide 2 on both sides.
x = 14/2
b is 7 i think
25-11=14÷2=7
cross multiplication:
4*10=2*x
40=2x
x=40/2=20
6.8w=2(4.5)
6.8w=9
w=9/6.8=1.32352941
3/4=6/8
hope this helps :)
its the second one
