Answer:
3.8918
round the 1 from the 8 to get 2
3.892
we have
6+6×8-5÷3+12
so
Applying PEMDAS
P ----> Parentheses first
E -----> Exponents (Powers and Square Roots, etc.)
MD ----> Multiplication and Division (left-to-right)
AS ----> Addition and Subtraction (left-to-right)
step 1
Multiplication
6x8=48
substitute
6+48-5÷3+12
step 2
Division
5÷3=5/3
substitute
6+48-(5/3)+12
step 3
Addition
6+48=54
54-5/3+12
step 4
S
Answer:
See attachment
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of all the sides of the rectangle, so it is given by:
where
L is the length
w is the width
In this problem, we want to find all the integer values of L and w such that the perimeter is 16 cm:
This means:
Or:
We have only 4 possible combinations:
L = 7 cm, w = 1 cm
L = 6 cm, w = 2 cm
L = 5 cm, w = 3 cm
L = 4 cm, w = 4 cm
The other combinations with L and w swapped are identical, so we don't include them; therefore, these are the only 4 possible combinations. The 4 possible rectangles are therefore draw in attachment.
Answer:
Part A is ≤ means less than OR equal to. < only means less than
Part B is 9
Step-by-step explanation:
A: Because it would equal 19, and 19 is equal than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.
B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.
Answer: (just the first question)
x=3
y=17
Step-by-step explanation:
3x+8=-5x+32
add 5x and subtract 8 from both sides
8x=24
divided by 8
x=3
substitute+simplify
y=3x+8
y=9+8
y=17
y=-5x+32
y=-15+32
y=17
