Answer:
95>=X <=100. More or equal to 95 or equal or less than 100.
Step-by-step explanation:
The Total of the first score is needed first
81+87+ 94+93=355
The total of this score
Let X be the 5TH score we are looking for
(355+ X)/5= 90
355+X= 450
X= 450-355
X= 95 the person needs to sore between 95 and 100 ( which is the highest possible score).
Answer:
Equation = y = -4x+7
See the graph below
Step-by-step explanation:
The equation of the line in slope intercept form is expressed as;
y = mx+c
Given
slope m = -4
y-intercept c = 7
Substitute
y = -4x + 7
Get the x intercept.
at y = 0
0 = -4x + 7
4x = 7
x = 7/4
x = 1.75
The x coordinate (1.75, 0)
Get the y intercept
at x = 0;
y = -4(0)+7
y = 0+7
y = 7
The y coordinate is (0, 7)
Answer:
-5 or 5 depending on how you write the simplified form
Step-by-step explanation:
__
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
1/a^b = a^-b
__
Some folks like their simplified form to contain only positive exponents. Other folks avoid unnecessary fractions. Choose the form that satisfies your grader.

Answer:
(b) 28
Step-by-step explanation:
The total of the 3 numbers will be 3×15 = 45. Then the third number is ...
