Answer:
x>0
Step-by-step explanation:
you can also write the expression like
√7x^2
----------
√3x
( I tried making a fraction above if you couldn't tell srry)
Also remember, if you're dividing by something, the denominator cannot be 0. So, a restriction is that x cant be 0. It can't also be negative, besides complex numbers, the root of a negative number is non-existant. So the value of x cannot be below 0. So the answer would be x>0.
X>0 because everything above 0 is positive and this inequality shows that it doesn't include 0 as well.

Answers
Answer:
4175.40384 Dutch guilders
Step-by-step explanation:
The main objective here is to convert the currency at hand (2,000 swiss francs) to Dutch guilders. In order to achieve that ; we need first require to convert the currency at hand into United states dollars
So ; if 1 swiss francs = 1.0328 united states dollars (as at Wednesday)

floral.
So in each group of 5, we have one floral quilt square.
now, in 125 quilt squares, we want to find the number of groups of 5 that we can make with thos 125 quilt squares.
This is 125/5 = 15
So we have 15 groups of 5 quilt square.
And we know that in each of those groups, we have one floral quilt square.
So we have a total of 15*1 = 15 floral quilt squars.
Answer: 25
Step-by-step explanation: 125 quilt square in group of 5
125/5 = 25
Each group of 5 os 1 floral quilt so there are 25 floral quilts in total

Solve algebraically
8x + 4y = 48
12x + 5y = 21
Answers
Answer:
[tex]x=-\frac{39}{2}\\ y=51[/tex]
Step-by-step explanation:
[tex]8x+4y=48\\12x+5y=21[/tex]
Let's solve the first equation for x or y. I'll do it for y.
[tex]8x+4y=48[/tex]
Subtract 8x
[tex]4y=-8x+48[/tex]
Divide by 4.
[tex]y=-\frac{8}{4}x+\frac{48}{4}\\[/tex]
Simplify.
[tex]y=-2x+12[/tex]
Now replace the value of y in the second equation for this.
[tex]12x+5y=21\\12x+5(-2x+12)=21[/tex]
Distribute 5
[tex]12x-10x+60=21[/tex]
Subtract 60
[tex]12x-10x=21-60[/tex]
Combine like terms;
[tex]2x=-39[/tex]
Divide by 2.
[tex]x=-\frac{39}{2}[/tex]
Now replace this in any of the equations to find the value of y.
[tex]8x+4y=48\\8(-\frac{39}{2})+4y=48\\[/tex]
8 and 2 can be simplified.
8/2=4
2/2=1
[tex]4(-39)+4y=48[/tex]
Distribute 4.
[tex]-156+4y=48[/tex]
Add 156
[tex]4y=48+156\\4y=204[/tex]
Divide by 4
[tex]y=\frac{204}{4}[/tex]
[tex]y=51[/tex]
Proof:
[tex]8x+4y=48\\8(-\frac{39}{2} )+4(51)=48\\4(-39)+204=48\\-156+204=48\\48=48[/tex]
-4y -4y
8x=48-4y
divide 8 to both sides
x=6-1/2y
substitute the given value of x into the equation 12x+5y=21
12(6-1/2y)+5y=21
distribute 12 through the parentheses
72-6y+5y=21
add like terms
72-y=21
move constant to the right hand side and change signs
-y=21-72
calculate the difference
-y= -51
change signs
y=51
solve the question for x
x= 6-1/2 x 51
x= -39/2
(x,y) = (-39/2 , 51)

Answer:
-2.6
Step-by-step explanation:
Slope or gradient is the ratio of the vertical (y axis) and horizontal distances (x axis) between two points on a line.
It should be noted that it is defined as zero if the line is horizontal, but undefined if it is vertical.
Given:
Coordinates (- 3, 7) (2, - 6)
y1 = 7, y2= -6, x1= -3, x2=2
Slope : ∆ y/ ∆ x
= (y2 - y1 )/ (x2 - x1)
= (-6 - (7))/ (2 - (-3))
= (-13)/(5) = -13:5= -2.6

A piepie is divided into 2020 equal pieces. GlennGlenn and SophieSophie each ate one fourth 1 4 of the piepie on MondayMonday. The next day, SophieSophie ate one fifth 1 5 of the piepie that was leftover. How many of the pieces of the original piepie remain? Explain your reasoning. Together, GlennGlenn and SophieSophie ate one fourth 1 4 piece(s) on MondayMonday, and SophieSophie ate one fifth 1 5 piece(s) the next day. To find the number of pieces that remain, add these numbers to the total number of pieces. So, 0.450.45 pieces of the original piepie remain.
Answers
Answer:
Pieces remaining = 1 - (1/4 + 1/4) - (1/2 x1/5) = 1/2 - (1/2 x1/5) = 1/2 - 1/10 = 4/10
Therefore, 4/10 x 20 = 8 pieces.
Step-by-step explanation:
Sophie ate 1/4 = 5 pieces
Glenn ate 1/4 = 5 pieces
Remaining pieces = 20 - 5 - 5 = 10 pieces
On Monday, Sophie ate = 1/5 x 10 = 2 pieces
Therefore, remaining pieces = 10 - 2 pieces = 8 pieces
Sophie and Glenn consumed half of the pie the first day. This is equal to 10 pieces. The remaining pieces will be 10. If, on Monday, Sophie ate 1/5 of 10 pieces, representing 2 pieces, the number left over is 10 Minus 2, which equals 8 pieces.
