Student's error is –5 < x.
Solution:
Step 1: Given inequality
31 < –5x + 6
Step 2: Subtract 6 from both sides of the inequality.
31 – 6 < –5x + 6 – 6
25 < –5x
Step 3: Multiply both sides by –1 to reverse the inequality.
25 × (–1) > –5x × (–1)
–25 > 5x
Step 4: Divide by 5 on both sides.
–5 > x
The correct answer is –5 > x.
Student's error is –5 < x.
To look for the area of a sector of a circle, the following formula is used:
Area = ( n / 360 ) * pi * r^2
Where: n = measure of arc in degrees
pi = 3.1416
r = radius
Since we are already given all of the needed parts of the formula, direct substitution is done, as shown below:
Area = ( n / 360 <span>) * pi * r^2
</span>Area = ( 45 / 360 ) *3.1416 * (8)^2
Area = 25.133 in^2
Therefore, the area of the sector of the circle is 25.133 sq. in.
The numbers or measurements Being compared or called the terms of the ratio a rate is a special ratio in which the two terms are in different units we can raise our expressed as a quantity of one such as 2 ft./s or 5 mph they are called unit rates
Answer:
option C
Step-by-step explanation:
The point slope equation of a line is given by
Where m is the slope and (x1,y1) is the point on the point
We need to write the equation in y=mx+b form
multiply -2/3 inside the parenthesis
Subtract 7 from both sides
Answer:
Alex has £44
Pierre has £66
Step-by-step explanation:
P = A + 20
P+ 22 = 2A
solve for A
plug in p
(A + 20) + 22 = 2A
A + 44 = 2A
subtract A from both sides
44 = A
solve for P
plug A in
P = 44 +22
P = 66
