Anja is substituting t=5 and t=9 to determine if the two expressions are equivalent. we have to choose the correct statement.
First exp: 4(2t-5)
Substitute
t=5: 4(2(5)-5)=4(10-5)=20
t=9: 4(2(9)-5)=4(18-5)=4(13)=52
Second exp: 10t-38
t=5: 10(5)-38=50-38=12
t=9: 10(9)-38=52
Both expressions are equivalent when t=9, but the two expressions are not equivalent.
Hence, correct option is C

Answer:
0.06 is 10 times as much as 0.006
Step-by-step explanation:
let the number be x
as per the condition 0.06 is 10 times as much as x.
Solve for x:
10 times as much as x represents as
Then;
......[1]
Division property of equality states that you divide the same number to both sides of an equation.
divide by 10 to both sides in equation [1];
Simplify:
x = 0.006
Therefore, 0.06 is 10 times as much as 0.006
