It would be written like so:
25/4 + 2
Though I'm not sure how you share 25 stamps among 4 friends equally without having to rip 1 of the 25 stamps into quarters.
Answer:
b
Step-by-step explanation:
Given
Substitute x = 3 into the expression
= 
= 
= 
= 0 → b
Answer:
B because 67 is more than 0.35
Answer:
2.3 × 10^-7
Step-by-step explanation:
First, create an equation with the initial decimal being the coefficient multiplied by 10 to the power of 0.
(For example, let’s create the starting scientific notation equation for the decimal 475,000).
475,000 = 475,000 × 10^0
-------------------------------------------------------------------------------------------------------------
Now that we have an equation, the second step is to move the decimal point in the coefficient until there is 1 significant digit to the left of the decimal point. For each space the decimal point is moved to the left, increase the exponent by 1.
(Continuing the example above, move the decimal point to the left and increment the exponent.).
475,000 = 475,000.0 × 10^0
475,000 = 47,500.0 × 10^1
475,000 = 4,750.0 × 10^2
475,000 = 475.0 × 10^3
475,000 = 47.5 × 10^4
475,000 = 4.75 × 10^5
Answer:
400 feet long
50 feet wide
Step-by-step explanation:
Length = l
Width = w
2l + 2w = 900
l = 8w
Plug the l from the bottom equation into the top equation
2 x 8w+ 2w = 900
16w = 900
Divide both sides by 16
16w/16 = 900/16
w = 50
The width is 50 feet
Now plug the new w into one of the original equations; we'll use the bottom one
l = 8(50)
l = 400
