Round to the nearest hundredth:7.884
Answer:
7.88
Step-by-step explanation:
Hope this helps :D
When rounding to the nearest hundredth, the number 7.884 becomes 7.88.
To round 7.884 to the nearest hundredth, we look at the digit in the thousandth place, which is 8.
Now, If the digit to the right is less than 5, you simply drop all the digits to the right and keep the desired decimal place unchanged.
If the digit to the right is 5 or greater, you round up the desired decimal place by increasing it by one. Drop all the digits to the right.
Since 8 is greater than or equal to 5, we round up the digit in the hundredth place.
Therefore, when rounding to the nearest hundredth, the number 7.884 becomes 7.88.

The orginal price of the chair was $545. The tax on the chair was 4.5%.What is the exact price of the chair including the tax?
Solve using substitution. I know that the answer is (1,1), but I have to show my work and I forgot how to do it.
If y = -x + 2, then substituting this into the first equation lets you solve for x :
x + 4y = 5
x + 4 (-x + 2) = 5
x - 4x + 8 = 5
-3x = -3
x = 1
Now solve for y :
y = -x + 2 = -1 + 2 = 1
So the solution is indeed (x, y ) = (1, 1).

Answer:
[tex]A=2x^2+3x-5[/tex]
Step-by-step explanation:
Given that,
Length = (2x+5) cm
Width = (x-1) cm
We need to find the area of a rectangle. The formula for the area of rectangle is given by :
A = lb
[tex]A=(2x+5)(x-1)\\\\=2x^2-2x+5x-5\\\\=2x^2+3x-5[/tex]
So, the required area is equal to [tex]2x^2+3x-5[/tex].

Given the function f(x) = 2 x + 61 - 4, for what values of x is f(x) = 6?
O x= -1, x = 11
Ox=-1, x = -11
O x= 14 = -26
O x= 26, x=-14
Answer:
[tex]x = -1[/tex] or [tex]x = -11[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2|x+6| - 4[/tex]
Required
Find x when
[tex]f(x) = 6[/tex]
Substitute 6 for f(x)
[tex]6 = 2|x+6| - 4[/tex]
Add 4 to both sides
[tex]4+6 = 2|x+6| - 4+4[/tex]
[tex]10 = 2|x+6|[/tex]
Divide both sides by 2
[tex]5 = |x + 6|[/tex]
Rewrite as:
[tex]|x + 6| = 5[/tex]
This can be split to:
[tex]x + 6 = 5[/tex] or [tex]-(x + 6)=5[/tex]
Solve for x in both cases
[tex]x = 5 - 6[/tex] or [tex]x + 6 = -5[/tex]
[tex]x = -1[/tex] or [tex]x = -6 - 5[/tex]
[tex]x = -1[/tex] or [tex]x = -11[/tex]
Answer:
i think it’s x= -1, x = -11
