Kruka [31]

Answer:

It simplifies to 2x + 2.

Step-by-step explanation:

Let the number be x, then the expression is

x + 5 + (x - 3)

= x + 5 + x - 3

= x + x + 5 - 3

What are the next two likely terms in each sequence:80.1, 85.3, 90.5, .
AnnyKZ [126]

Answer:

We have 85.3 - 80.1 = 5.2 and 90.5 - 85.3 = 5.2;

So, the next two likely terms are: 90.5 + 5.2 = 95.7 and 95.7 + 5.2 = 100.9;

The spring has a stiffness k=200n/m and is unstretched when the 25 kg block is at
g100num [7]
To solve this we are going to use the formula fro the force applied to a spring: F=ks
where
k is the spring constant 
s is the extension 

Since we know the F=ma, we can replace that in our formula and solve for a :
ma=ks
a= \frac{ks}{m}
where
a is the acceleration 
k is the spring constant
s is the extension 
m is the mass

We know for our problem that k=200, s=0.4, and m=25. So lets replace those values in our formula to find a:
a= \frac{ks}{m}
a= \frac{(200)(0.4)}{25}
a=3.5 \frac{m}{s^2}

We can conclude that the acceleration of the block when s=0.4m is 3.5 \frac{m}{s^2}.
