Answer:
4 weekdays and 2 weekends.
Step-by-step explanation:
6 days.
x = weekdays
y = weekends
7x = amount with weekdays
12y = amount with weekends
7x + 12y = 52, total
x + y = 6, amount of days
solve double variable equation
x = 6 - y, plug in to 1st equation
7(6 - y) + 12y = 52
42 - 7y + 12y = 52
5y = 10
y = 2 weekends
2 + x = 6
x = 4 weekdays
Answer:
4x-2y =42 is the required equation
Step-by-step explanation:
given equation is,
4x-2y -7=0---------eqn1
parallel equation of given equation is
4x -2y+k =0-------eqn 2
now passing it through (9,-3), we get,
4×9 + 2×3 +k = 0
or,36+6+k =0
or,42+k =0
or, k= -42
putting the value of k in eqn2
4x-2y - 42=0
4x-2y = 42

Answer:
3000 ft³
Step-by-step explanation:
The area of a rectangle is:
Height x length x width
So simply plug the given values in:
20 x 15 x 10 = 3000
<h3>So the volume is 3000 ft³</h3>

Answer:
x=13+√-13 or x=13-√-13
Step-by-step explanation:
Using the method of completing the square roots:
x²-26x=-13-169
x²-26x=-182
x²-26x+(-13)²=-182+(-13)²
(x-13)²=-182+169
(x-13)²=-13
Take square roots of both sides
(x-13)=√-13
x=13±√-13
That can also be written as
X=13+√13i,13-√13i
Answer: the answer should be 7
Step-by-step explanation: V=πr2h
3=π·1.52·3
3≈7.06858
you can find the radius for the area of the base 7 by dividing by like such 7/3.1459 the squared because remember its in r2 form which give you 1.5 then plug this in for one of two ways to solve A· 1/3 or V=πr2h
