Answer:
t = 4
Step-by-step explanation:
13 + t = 17
t = 4
13 + 4 = 17
An easier way to solve a question like this is to subtract the number given by the answer.
Example:
17 - 13 = 4
Answer:
the equation should be A, 13+t=17
which means t=4
Step-by-step explanation:
13+4=17 which checks our work that the answer should be 4.
you can also do: 17-13 which also gives you 4, if this way is easier for you.
thank you! hope this helps :D

Find the slope of the line passing through the points (-2, 5) and
(3/2 , 2)
Answer:
m=-6/7
Step-by-step explanation:
the formula of a slope is m=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
where [tex]x_{1}=-2,x_{2}=3/2, y_{1}=5, y_{2}=2\\[/tex]

Use graphing method y=3x-2 and y=-x
Answer:
x = 0.5 and y = -0.5
Step-by-step explanation:
The given equations are :
y=3x-2 .....(1)
and
y=-x .....(2)
Use (2) in (1). So,
-x=3x-2
Taking like terms together,
2 = 3x+x
2 = 4x
x = 1/2 = 0.5
So,
y = -1/2 = -0.5
The graph is shown in the attached figure.

I think what you are asking for is an example.
Step-by-step explanation:
Standard form equation
8x-4y = 20
1. move 8x to the other side
-4y=20-8x
2. divide both sides by -4

Find the slope of the line below
Answer:
-2
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Given that the two points (-12, 10) and (-10, 6) lie on the line,
slope of the line
[tex] = \frac{10 - 6}{ - 12 - ( - 10)} [/tex]
[tex] = \frac{4}{ - 12 + 10} [/tex]
[tex] = \frac{4}{ - 2} [/tex]
[tex] = - 2[/tex]
Extra:
The line has a negative slope as looking from the left to right, the line is sloping downwards.

Find the probability that a randomly
selected point within the circle falls
in the white area.
60°
60°
r = 4 cm
[? ]%
Round to the nearest tenth of a percent.
Answer:
probability is 0.67
Step-by-step explanation:
We know that Angle in a circle = 360°
Area of total shaded parts = 60 + 60 = 120°
Area of total unshaded parts = 360-120 = 240°
Probability that a random selected point within the circle falls in the unshaded area
= 240/360
= 2/3= 0.67
Probability that a randomly selected point within the circle falls in the white area will be [tex]0.67[/tex] .
What is Probability ?Probability is the ratio of the number of outcomes to the total number of possible outcomes.
Probability [tex]=\frac{Number\ of\ possible\ outcomes}{Total\ number\ outcomes}[/tex]
We have,
Radius [tex]=4[/tex] cm
Now,
Area of Circle [tex]=\pi r^{2}[/tex]
Area of Circle[tex]=\frac{22}{7} *4^2=50.28\ cm^2[/tex]
Now,
Area of minor segment [tex]=\frac{\theta}{360^0} *\pi r^{2}[/tex]
Area of minor segment [tex]=\frac{60}{360} *\frac{22}{7}* 4^{2}=8.38\ cm^2[/tex]
Now,
We have two minor segment,
Area of two minor segment [tex]=8.38*2=16.76\ cm^2[/tex]
Now,
Area of white Portion [tex]=50.28-16.76=33.52\ cm^2[/tex]
Now,
Probability [tex]=\frac{Number\ of\ possible\ outcomes}{Total\ number\ outcomes}[/tex]
Probability [tex]=\frac{33.52}{50.28}=0.67[/tex]
So, the Probability of white area is [tex]0.67[/tex] .
Hence, we can say that Probability that a randomly selected point within the circle falls in the white area will be [tex]0.67[/tex] .

Find the value of x in the isosceles triangle shown below.
Answer:
B
Step-by-step explanation:
Since the triangle is isosceles, then the segment from the vertex is a perpendicular bisector and the triangle is divided into 2 right angles with legs 12 and [tex]\frac{1}{2}[/tex] x with hypotenuse 15
Using Pythagoras' identity in the right triangle
( [tex]\frac{1}{2}[/tex] x )² + 12² = 15²
[tex]\frac{1}{4}[/tex] x² + 144 = 225 ( subtract 144 from both sides )
[tex]\frac{1}{4}[/tex] x² = 81 ( multiply both sides by 4 to clear the fraction )
x² = 324 ( take the square root of both sides )
x = [tex]\sqrt{324}[/tex] = 18 → B
Find the distance between 6.2 and
-4.3 on a number line.
Answer:

a. Work out the area of his room in Square meters.
b. How much does he pay to buy flooring for his room where flooring costs $ 40 per square meter
Question No. aWork out the area of his room in Square meters.
Given:-Length of the room 540 cm = 540/100 m = 5.4mBreadth of the room 250cm = 250/100 m = 2.5mTo Find:-Area of the room. Solution:-We know that:-
Area of a rectangle = (length × breadth)sq.units
Therefore,
Area of the rectangular room = (5.4 × 2.5) square meters
=> Area of the rectangular room = 13.5 square meters.
Answer:-Area of his room is 13.5 square meters.
Question No. bHow much does he pay to buy flooring for his room where flooring costs $ 40 per square meter
Given:-Cost in per square meter = $40Area of the room = 13.5 square meters (From question a) To Find:-Total cost of flooringSolution:-Flooring cost in 1 squre meter = $40
Flooring cost in 13.5 square meters = $(40 × 13.5) = $540
Answer:-He pays $540 to buy flooring for his room.

Given
See attachment for grid
Required
Distance AC
From the attachment:
[tex]A = (-7,6)[/tex]
[tex]C = (5,-5)[/tex]
Distance (d) is calculated using:
[tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2[/tex]
This gives:
[tex]d = \sqrt{(-5 - 6)^2 + (5 - (-7))^2[/tex]
[tex]d = \sqrt{121 + 144[/tex]
[tex]d = 16.28[/tex]
