<h3>
Answer: 120</h3>
=============================================
Explanation:
S = sum of the first four values
S/4 = 70 since we divide the sum by 4 to get the mean of the first four values
S = 280 is the result after multiplying both sides by 4
Let x be the fifth unknown value. Adding it onto S leads to S+x = 280+x. This represents the sum of all five values.
Dividing that sum 280+x over 5 leads to the new mean 80, which leads to...
----------
(280+x)/5 = 80
280+x = 5*80
x+280 = 400
x = 400-280
x = 120
The fifth number is 120
Answer:
Answer simultaneously :)
Input equation 1 into equation 2
xtan60*=(40-x)tan30*
xtan60/tan30= (40-x)
3x = 40-x
4x = 40
x = 10
Hope this helps :) !
I'd appreciate if you'd mark my answer brainliest because ive been stuck on the same rank for wayyy too long :(
Goodluck! :)
Answer:
y=1/4x + 1
Step-by-step explanation:
first equation,,y=1/4x - 1
G1 = G2
G2 = 1/4
y+1 /x+8 =1/4
4y = X + 8 -4
4y =x + 4
y = 1/4x + 1
Answer:
The absolute value
Step-by-step explanation:
we know that
The modulus of a real number, is equal to the absolute value of the real number
so
The modulus of a positive number is simply the number and the modulus of a negative number is found by ignoring the minus sign.
Then
modulus of n is always positive number .such that n belongs to real number R.
Modules of n is denoted by |n|
<u><em>Examples:
</em></u>
|-4|=4
|2.5|=2.5
|-100.1|=100.1
