Hey there!☺
[tex]Answer:\boxed{t=2}[/tex]
[tex]Explanation:[/tex]
[tex]5t-9=-3t+7[/tex]
Let's start by adding 3t to both sides of the equation.
[tex]5t-9+3t=-3t+7+3t\\8t-9=7[/tex]
Now let's add 9 to both sides of the equation.
[tex]8t-9+9=7+9\\8t=16[/tex]
Now let's divide both sides by 8.
[tex]\frac{8t}{8} =\frac{16}{8}[/tex]
Now let's simplify 16/8.
[tex]16/8=2[/tex]
[tex]t=2[/tex]

Courtney and Malik are buying a rug to fit in a
50-square-foot space, Which rug should they
purchase? Explain.
$99 Rug Sale!
7 ft x 7 ft
8 ft diameter
6 ft x 8ft
Rug Emporium has your floors covered.
Answer:
I think its 7x7 because it equals to 49 and its the closest to 50 and the rug would fit better than 6x 8 1/2=51 becuase 49 is smaller and would fit better.
Step-by-step explanation:
The area of a 2D form is the amount of space within its perimeter. The correct option is B, 8ft diameter.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Since Courtney and Malik want the rug to fit in an area of 50-square-foot space. Therefore, we need to first calculate the area of the given rugs, and then choose the one that can completely cover the area.
7 ft x 7 ft → Area = 7 ft x 7 ft = 49 ft²8 ft diameter → Area = (π/4)×Diameter² = (π/4)×(8ft²) = 50.2654 ft² 6 ft x 8ft → Area = 6 ft x 8ft = 48 ft²Now, as it can be seen that the only rug that can completely cover the 50-square-foot area is the one that has a diameter of 8 ft.
Hence, the correct option is B, 8ft diameter.

Differentiate y=(sinx)(3x^2) please help please !
Answer:
6xsinx + 3x²cosx
Step-by-step explanation:
Differentiate using the product rule
Given y = f(x)(g(x) , then
[tex]\frac{dy}{dx}[/tex] = f(x)g'(x) + g(x)f'(x)
Here f(x) = sinx ⇒ f'(x) = cosx
g(x) = 3x² ⇒ g'(x) = 6x
Thus

Step-by-step explanation:
this relation is not a function cuz each x pair (domian) has only one image in y pair (codomain) so we will have all the ×-axis pairs meeting with y-axis in only one point as they have one image as this is the rule of having a function so what in front of us the positive part of x-axis has two images in y-axis
u can knew it by another way draw a vertical line and if it meets in two point or more than one then the relation is not a function s o if we draw a vertical line in the right part of the graph it will meats in two points then not a function
the domain is all the pairs of this relation taken in x-axis which are [0,infinity[ and range is the y-axis images if the fomain in x-axis which are ]-infinity, infinity[

Angle XYZ = 2X ° and angle PQR = (8X -20)° if angle XYZ and angle PQR or supplementary find the measure of each angle angle XYZ = ?
Answer:
angle XYZ = 40°
Step-by-step explanation:
given,
angle XYZ = 2x°
angle PQR = (8x-20)°
now,
2x+8x-20° = 180°{being supplementary angle}
or, 10x - 20° = 180°
or, 10x = 180°+20°
or, x = 200°/10
or, x = 20°
again,
angle XYZ = 2x°
= 2× 20°
= 40°

1 7/8 can be written as 8*1+7/8=15/8=1.875
Step-by-step explanation:
A cube has a volume of 216 cubic inches. What is the length of each edge of the cube?
Volume of a cube = (edge)^3
In this problem,
Volume = 216in^2
Edge = ?
Let's plug our values into the formula above.
216in^3 = (edge)^3
Take the cbrt of both sides.
6in = edge
The length of each edge = 6in
Answer:
[tex]\boxed {\tt 6 \ centimeters}[/tex]
Step-by-step explanation:
The volume of a cube can be found using the following formula:
[tex]v=s^3[/tex]
where [tex]s[/tex] is the side length, or edge.
We know the volume is 216 cubic inches. We can substitute 216 cm³ in for [tex]v[/tex], the volume.
[tex]216 \ cm^3 = s^3[/tex]
We want to find the side length. Therefore, we must isolate the variable, [tex]s[/tex].
s is being cubed. The inverse of a cube is the cube root. Take the cube root of both sides of the equation.
[tex]\sqrt[3]{216 \ cm^3} =\sqrt[3]{s^3}[/tex]
[tex]\sqrt[3]{216 \ cm^3} =s[/tex]
[tex]6 \ cm=s[/tex]
The length of each edge of the cube is 6 centimeters.

Hey there! I'm happy to help!
From G to I is the total distance of the line (92). G to H is the first portion of the line (72) while H to I is the other portion.
To find H to I, simply subtract 72 from 92!
92-72=20
The distance from city H to city I is 20 miles.

Solve x − 2y = 3 for x.
Answer:
[tex]x=2y+3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]x-2y=3[/tex]
And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.
[tex](x-2y)+2y=(3)+2y[/tex]
On the left, the 2y cancel. Simplify the right:
[tex]x=2y+3[/tex]
And we're done!
Answer:
x = 3 + 2y
Step-by-step explanation:
This is the answer because:
1) First, you have to isolate x, in order to isolate x you have to bring x to the end of the equation.
2) Then, you have to add 2y to both sides of the equation.
Another way you can think of this is:
1) If you add 3 + 2y you would figure out the answer because if you want to find x for a subtraction equation, you can add the answer to the equation with the number.
For example, x - 20 = 10, now to figure this equation out, you can either isolate the x, or you can add the answer in the equation with the remaining number in the equation.
