3x + y = 25
Answer:
I can help!
In point form: (5,10)
In equation form: x=5 y=10
Explanation
Solve for the first variable in one of the equations (y=x+5), then substitute the result in the other equation.
Examine the system of equations.
2x − 4y = 6
x − 2y = 3
How many solutions does this system of equations have?

15 less than 2 times a number is the same as 7 more than half of the number. what is the number?
Answer:
x = 14 and 2/3
Step-by-step explanation:
Make an equation where x is the number.
2x - 15 = 7 + 1/2x
Then, solve the equation.
multiply both sides by 2 to get rid of the fraction
4x - 30 = 14 + x
subtract x from both sides
3x - 30 = 14
add 30 to both sides
3x = 44
divide both sides by 3
x = 14 and 2/3
The graph shows quadrilaterals Q and R.

Which statement justifies whether or not the two quadrilaterals are congruent?
O A. Yes, because R is the result of reflecting Q across the x-axis.
B. Yes, because R is the result of reflecting across the line y = x.
OC. No, because R can only be obtained from Q by a series of rigid transformations.
OD. No, because R cannot be obtained from Q by a series of rotations and translations.
OE. Yes, because R is the result of rotating Q by 90° counter-clockwise about the origin.

Which statement is true? A. All rhombuses have all sides equal. All quadrilaterals are rhombuses, so they have all sides equal. B. All quadrilaterals have four sides. All rhombuses are quadrilaterals, so they have four sides. C. All rhombuses have opposite sides parallel. All quadrilaterals are rhombuses, so they have opposite sides parallel D. Some quadrilaterals have four night angles. All rhombuses are quadrilaterals, so they have four right angles
Answer:
A
Step-by-step explanation:
It should be A
What is the measure of angle Y?
Answer:
Y=70
Step-by-step explanation:
For starters, all the interior angles inside a pentagon add up to 540. This number can be found for any polygon with the forumla (n-2)180. N stands for the number of sides and then you plug it into the equation. For instance, if we wanted to find it for a triangle, we would see that the triangle has three sides and plug it into the formula. (3-2)180 which equals 180. For the ptenagon we take the fact that it has five sides and add it into the equation. (5-2)180 which equals 540. So now that we know all the interior angles are supposed to add up to 540, we can find the value of Y. So let's start by finding what amount we already have.
T=110
A=150
D=120
O=90 (this is beacuse of the right angle square placed which equals 90 degrees)
All those angles add to 470 degrees. So to find the last angle, you would subtract our total of 470 from our interior angle total of 540.
540-470=70
Y=70.
50m.cloth costs 2500$.so how much meters will be bought in 1000$
Step-by-step explanation:
50m.cloth costs=2500$
we can write,
2500$cost for=50m.
1$ costs for=[tex]\tt{\dfrac{50}{2500} }[/tex] ⠀
=[tex]\tt{\dfrac{\cancel{50}}{\cancel{2500}} }[/tex]m. ⠀
=[tex]\tt{\dfrac{1}{50} }[/tex] m.⠀
So,
1000$ cost for ,
=[tex]\tt{\dfrac{1}{50}×1000 }[/tex]
=[tex]\tt{\dfrac{1}{\cancel{50}}×\cancel{1000 }}[/tex]
=[tex]\tt{20m. }[/tex] ⠀
[tex]\therefore[/tex] 20m. Will be bought in 1000$⠀
Answer:
The 20m of cloth will be bought in $1000.
Step-by-step explanation:
Given that :-
The cost of 50m cloth is $2500.
We need to find :-
How much meters of cloth will be bought in $1000.
Let us assume :
We bought x meters of cloth in $1000.
According to the question
50 = 2500
x = 1000
Using cross multiplication method.50 × 1000 = 2500 × x
50000 = 2500x
Divide both side by 2500.[tex]\frac{50000}{2500} \\ [/tex] = [tex]\frac{2500x}{2500} \\ [/tex]
Reduce the fractions.20 = x
Hence,
The 20m of cloth will be bought in $1000.

What is RS? Please help will give Brainlyest.
Answer:
RS = 47Step-by-step explanation:
RV=VU and SW=WT ⇒ [tex]VW=\dfrac{RS+UT}{2}[/tex]
Therefore:
[tex]3x+5=\dfrac{2x+15+6x-37}{2}\\\\3x+5=\dfrac{8x-22}{2}[/tex]
3x + 5 = 4x - 11 {subtract 5 from both sides)
3x = 4x - 16 {subtract 4x from both sides)
-x = -16 {divide both sides by (-1)}
x=16
So:
RS = 2x + 15 = 2×16 + 15 = 32 + 15 = 47
A bag has 2 blue, 3 red, and 5 yellow tiles. Find the probability of picking a blue tile.
Given:
A bag has 2 blue, 3 red, and 5 yellow tiles.
To find:
The probability of picking a blue tile.
Solution:
We have,
Number of blue tiles = 2
Number of red tiles = 3
Number of yellow tiles = 5
Total number of tiles = [tex]2+3+5[/tex]
= [tex]10[/tex]
Now, the probability of picking a blue tile is
[tex]P(\text{Blue})=\dfrac{\text{Number of blue tiles}}{\text{Total number of tiles}}[/tex]
[tex]P(\text{Blue})=\dfrac{2}{10}[/tex]
[tex]P(\text{Blue})=0.2[/tex]
Therefore, the probability of picking a blue tile is 0.2.

Three of the angles of a
quadrilateral measure 36', 72, and
144. Which one of the following could
be the measure of the fourth angle
of the quadrilateral?
