Answer: 275$
I'm not entirely sure I did this right! But at least try!!!
Step-by-step explanation:
20/100 = 55/x (cross multiply)
20x = 5,500 (divide)
X = 275
2 x 230 = 231
I’m not 100% sure if this is correct?? Hope it helps though
Number 6
Answer:
y = (c - ax)/b
Step-by-step explanation:
ax + by = c
by = c - ax
y = (c - ax)/b

Answer:
96
Step-by-step explanation:
First we need to know the mean of the Steve's scores on 6 of his tests. Given the six scores as 92, 78, 86, 92, 95, and 91.
Mean = sum of the scores/Total test taken
Mean = 92+78+86+92+95+ 91/6
Mean = 534/6
Mean = 89
If he took the seventh test and the mean score is raised by 1 them the new mean will be expressed as;
New mean = 92+78+86+92+95+ 91+x/7 = 89+1
Where x is the new score. Note that of a new score is added, the total year taken will also change to 7
To get x;
92+78+86+92+95+ 91+x/7 = 89+1
92+78+86+92+95+ 91+x/7 = 90
534+x/7 = 90
Cross multiply
533+x = 90×7
533+x = 630
x = 630-534
x = 96
Hence the score of the seventh test is 96
The corresponding values needed will be -23, -8, 7 and 22
<h3>Functions and Tables</h3>
Given the function y = 5x - 8
<h3>Get the domains and range</h3>
We are to get the range of the function for the given domains
If the value of x is -3
y = 5(-3) - 8
y = -15 - 8
y = -23
If the value of x is 0
y = 5(0) - 8
y = 0 - 8
y = -8
If the value of x is 3
y = 5(3) - 8
y = 15 - 8
y = 7
If the value of x is 6
y = 5(6) - 8
y = 30 - 8
y = 22
Hence the corresponding values needed will be -23, -8, 7 and 22
