How does the value of the digit 2 in the number 32,000 compare with the value of the digit 2 in the number 26,000?
Answer: See explanation
Step-by-step explanation:
We should note that the value of the digit 2 in the number 32,000 is 2 thousand. The value of the digit 2 in the number 26,000 is 20 thousand = 20,000.
We can simply say that the value of the digit 2 in 26000 is ten times the value of the digit 2 in 32000.

Question
Set up and solve a system of equations to solve the problem.
A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of
the coins is $1.30. How many nickels and how many dimes are in the jar?
The jar contains
nickels and
dimes.
9514 1404 393
Answer:
14 nickels6 dimesStep-by-step explanation:
The system of equations can be written ...
n + d = 20 . . . . . . . . coins in the jar
5n +10d = 130 . . . . . value in cents
_____
Using the first equation, we can write an expression for n:
n = 20 -d
We can substitute this into the second equation:
5(20 -d) +10d = 130
100 +5d = 130 . . . . . . simplify
5d = 30 . . . . . . . . . . . . subtract 100
d = 6 . . . . . . . . . . . . divide by 5
n = 20-d = 14
The jar contains 14 nickels and 6 dimes.

Answer:
The Area of the given figure is 6 inch²
Step-by-step explanation:
For a given Trapezoid
side a = 1 ½ = 1.5 inch
side b = 2½ = 2.5 inch
height (h) = 3 inch
Now, Area of Trapezoid
Formula:A = ½ (a + b) × h
A = ½ (1.5 + 2.5) × 3 inch
A = ½ × 4 × 3 inch
A = 2 × 3 inch
A = 6 inch²
Thus, The Area of the given figure is 6 inch²

Decide whether ABCD with vertices A (3,8) B (6,5) C (5,4) , and D (2,7) is a rectangle a rhombus or a square
Given:
The vertices of the quadrilateral ABCD are A(3,8), B(6,5), C(5,4), and D(2,7).
To find:
Whether the given quadrilateral is a rectangle, a rhombus or a square.
Solution:
Distance formula: The distance between two points is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, the side lengths are:
[tex]AB=\sqrt{\left(6-3\right)^2+\left(5-8\right)^2}[/tex]
[tex]AB=\sqrt{\left(3\right)^2+\left(-3\right)^2}[/tex]
[tex]AB=\sqrt{9+9}[/tex]
[tex]AB=\sqrt{18}[/tex]
[tex]AB=3\sqrt{2}[/tex]
Similarly,
[tex]BC=\sqrt{\left(5-6\right)^2+\left(4-5\right)^2}=\sqrt{2}[/tex]
[tex]CD=\sqrt{\left(2-5\right)^2+\left(7-4\right)^2}=3\sqrt{2}[/tex]
[tex]AD=\sqrt{\left(2-3\right)^2+\left(7-8\right)^2}=\sqrt{2}[/tex]
The length of diagonals are:
[tex]AC=\sqrt{\left(5-3\right)^2+\left(4-8\right)^2}=2\sqrt{5}[/tex]
[tex]BD=\sqrt{\left(2-6\right)^2+\left(7-5\right)^2}=2\sqrt{5}[/tex]
From the above calculation, we conclude that the given quadrilateral has two pairs of congruent opposite sides and equal diagonals.
Opposite sides of a rectangle are equal and its diagonals are also equal.
Therefore, the given quadrilateral ABCD is a rectangle.

s y=x+7
y = 6x + 2
Solution:
How do you solve this
Step-by-step explanation:
y=x+7........eqni
y=6x+2.....eqnii
putting the value of x in eqnii
y=6x+2
or, x+7=6x+2
or, 7-2=6x-x
or 5= 5x
hence,x=1
sbstutuung the value of x in eqni,
y= x+7
=1+7
=8
hence the value of y is 8

Answer: 1/2+11/3 = 4.1*6
Step-by-step explanation:
Answer:
1 5/6
Step-by-step explanation:
2 and 3 both have an LCM of 6, so in order to combine them you have to make the denominators 6. To do that, you multiply 1/2 by 3, and 1/3 by 2. When you do that, you get 3/6 and 1 2/6. When you add those, you get 1 5/6.
Jill and Gary share £63 in the ratio 2:5
Work out how much each person gets.
Answer:
Jill gets €18 Gary gets €45.
Step-by-step explanation:
First you add the two numbers of the ratio together. 2+5=7. Then you divide the constant, 63, by the total of the ratio, 7. 63/7=9. Then you multiply each number of the ratio by the quotient. 2 x 9= 18. 5 x 9= 45.

−5x + y = −2 −3x + 6y = −12 solved by substitution please work so i can understand
Answer:
x=0 and y= -2
Step-by-step explanation:
−5x+y=−2for y:
−5x+y=−2
−5x+y+5x=−2+5x(Add 5x to both sides)
y=5x−2
5x−2foryin−3x+6y=−12:
−3x+6y=−12
−3x+6(5x−2)=−12
27x−12=−12(Simplify both sides of the equation)
27x−12+12=−12+12(Add 12 to both sides)
27x=0
x=0
Substitute0 for X in y=5x−2:
y=5x−2
y=(5)(0)−2
y=−2(Simplify both sides of the equation)
Streets in the city can be represented by the equations in the given table. Use the equations to find the type of quadrilateral that the streets form. Justify your answer.
Answer:
It is a rhombus.
Step-by-step explanation:
We have the four equations:
3x - y = -4
3y - x = 4
3y = x + 12
y = 3*x - 4
First, we need to write all of them in slope-intercept form, so they are easier to read.
We get:
y = 3*x+ 4
y = (1/3)*x + 4/3
y = (1/3)*x + 12/3
y = 3*x - 4
First, we can see that:
y = 3*x+ 4 and y = 3*x - 4
are parallel lines, because they have the same slope.
y = (1/3)*x + 4/3 and y = (1/3)*x + 12/3 also are parallel lines, because they have the same slope.
Then this is a parallelogram.
Now, here we have two slopes, 3 and 1/3.
Remember that for a line y = a*x + b
A perpendicular line would be written as:
y = -(1/a)*x + c
From this we can see that there are no perpendicular lines in our set of lines.
Then this can not be a square nor a rectangle.
It can not be a trapezoid, because we would need 3 different slopes to make a trapezoid, and here we have only two.
Then this can only be a rhombus.
Below you can see the graph of the four lines to see which quadrilateral they form.
