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]

Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 4 equal parts. B. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 8 parts. C. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 5 equal parts. D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Answer:
I believe the answer is D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Step-by-step explanation:
She can make 10 dresses if you split the number line into 20 parts and find 2/5. Therefore, it would then be grouped into 10 parts, each part 2/5ths of a yard.

That passes through (-4,0) and is parallel to y= -2x+1
Answer:
y = -2x - 8
Step-by-step explanation:
Parallel lines always have the same slope. Here, it is -2.
So, our equation so far looks like this:
y = -2x + b, where b is the y-intercept
We need to find b. We know our line passes through (-4, 0), so let's plug -4 in for x and 0 in for y:
y = -2x + b
0 = -2 * (-4) + b
0 = 8 + b
b = -8
Since b = -8, our equation is thus y = -2x - 8.

Question 5 of 10
Solve 2x + 4 > 16.
O A. x<10
O B. x> 10
O C. x>6
O D. x< 6
Answer:
C
Step-by-step explanation:
2x +4 > 16
If you plug in 6 where the x is, and multiply 2 by 6, you get 12. Add 4 to 12 to get 16. If x is 6 it equals 16, so if x > 6 the answer will be more than 16.
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°
The afternoon temperature in Biscoff Bay was – 2°F. By midnight, a warm front moved in and the temperature rose to 11°F. What was the change in temperature from afternoon to midnight? To solve the problem, Ross subtracted 11–( – 2) and came up with an answer of 13°F. Is Ross correct? Why or why not?
Answer:
Ross is correct. He is right because if you do 11- (-2) the double negatives turn into a positive and the answer is 13.
The answer is "Yes", Ross is right, and the temperature change will be 13 °F.

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.

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.

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

For the function g(x) = x – 2x^2, find g (–3) + 13
Answer:
g( - 3) + 13 = - 2Step-by-step explanation:
g(x) = x - 2x²
To find g( - 3) + 13 substitute the value of x that's - 3 into g(x) and add 13 to it
We have
g( - 3) + 13 = - 3 - 2(-3)² + 13
= -- 3 - 2(9) + 13
= 3 - 18 + 13
We have the final answer as
g( - 3) + 13 = - 2Hope this helps you

4. Find the width of a rectangle if the perimeter is
14.00 inches and the length is 3.6 inches.
Answer:
The width of the rectangle is 3.4 inches
Step-by-step explanation:
3.6 inches = length LxW=Area
W= width
Perimeter= 2x(Length)+2x(Width) 2x3.6=7.2
7.2+2(W)=14.00 subtract 7.2 on both sides 14.00-7.2=6.8
2(Width)=6.8 divide both sides by 2 6.8/2=3.4
So width of rectangle is 3.4
