Answer:

2) 476.637

7) 2.2 and 2.20

8) 8.10 and 8.100

9) 9.5 and 9.500

10) 4.2 and 4.20

Step-by-step explanation:

2) First, solve 1/10 1/100, and 1/1000. That would be 0.1, 0.01, and 0.001.

Then, add all the numbers up. Do multiplication first. 4 x 100 = 400. Your answer would be 400 + 70 + 6 + 0.6 + 0.03 + 0.007. Add the big numbers. 476 + 0.637.

7) 2.2 and 2.20. It doesn't change the value no matter how many 0's you put.

8) 8.10 and 8.100

It doesn't change the value no matter how many 0's you put.

9) 9.5 and 9.500

It doesn't change the value no matter how many 0's you put.

10) 4.2 and 4.20

It doesn't change the value no matter how many 0's you put.

Choose all that correctly solve for x.

Tamiku [17]

Answer:

Options: A, B, and C correctly solve for x.

Step-by-step explanation:

A).

$\frac{5}{2} x$ = $\frac{15}{2}$

Multiplying both sides by 2 gives;

5x = 15

x = 15 ÷ 5 = 3

∴ This option correctly solve for x.

B).

x + $\frac{7}{2}$ = 7

x = 7 - $\frac{7}{2}$ = $\frac{14}{2} -\frac{7}{2} = \frac{7}{2}$

∴ This option correctly solve for x.

C).

x + 3 = $\frac{21}{5}$

x = $\frac{21}{5} - \frac{15}{5} = \frac{6}{5}$

But the option give x as 5/6 hence this option does not correctly solve for x.

D).

5x = 11/2

x = 11/2 ÷ 5 = 11/2 × 1/5 = 11/10

But the option gives x as 10/11 so it does not correctly solve for x.

Given the arithmetic sequence: u(1)= 124, u(2)= 117, u(3)= 110, u(4)=103,...

omeli [17]

We are given

arithmetic sequence: u(1)= 124, u(2)= 117, u(3)= 110, u(4)=103

so, first term is 124

u(1)= 124

now, we can find common difference

$d=u(2)-u(1)$

$d=117-124$

$d=-7$

now, we can find kth term

$u(k)=u(1)+(k-1)d$

now, we can plug values

and we get

$u(k)=124+(k-1)*-7$

$u(k)=124-7k+7$

$u(k)=131-7k$

u(k) must be negative

so,

$u(k)=131-7k$

$131-7k$

now, we can solve for k

$7k>131$

$k>18.714$

so, it's closest integer value is

$k=19$ ..............Answer
