Step-by-step explanation:
The point (3,8) is not a solution of system of equation. Explanation given below.
What is the system of equation?Simultaneous equations are any equations with the same number of unknowns that may be solved at the same time. The system of equations is a simultaneous equation.
Given system of equation,
y=7x + 8
y=x + 1
To find that the point (3,8) is a solution of system of equation,
we substitute the point to both of these equation and verify if that point is satisfying the equation or not.
In the first equation, x=3 and y =8
we get, 8 = 29
which is contradiction.
In the second equation ;
we get, 8 = 4.
Which is also contradiction.
Therefore, the equations do not have the solution (3 , 8).

A coin purse contains d dimes and q quarters. There are 35 coins in the purse, and the total value of the coins is $5.60. Create the system of linear equations and use it to find how many dimes and quarters are in the purse.
Answer:
14 dimes, 21 quarters
Step-by-step explanation:
Represent dimes with d and quarters with q.
So: 35 coins means
[tex]d + q = 35[/tex]
1 dime = $0.10 and 1 quarter = $0.25. So, a value of $5.60 means
[tex]0.10d + 0.25q = 5.60[/tex]
So, the system of equations is:
[tex]d + q = 35[/tex]
[tex]0.10d + 0.25q = 5.60[/tex]
Make d the subject in [tex]d + q = 35[/tex]
[tex]d = 35 - q[/tex]
Substitute 35 - q for d in [tex]0.10d + 0.25q = 5.60[/tex]
[tex]0.10d + 0.25(35 - q) = 5.60[/tex]
Open bracket
[tex]0.10d + 8.75 - 0.25q = 5.60[/tex]
Collect Like Terms
[tex]0.10d - 0.25q = 5.60 - 8.75[/tex]
[tex]-0.15q = -3.15[/tex]
Solve for q
[tex]q = \frac{-3.15}{-0.15}[/tex]
[tex]q = 21[/tex]
Substitute 21 for q in [tex]d = 35 - q[/tex]
[tex]d = 35 - 21[/tex]
[tex]d = 14[/tex]

Solve for x:
5x - 4 = 41
Answer:
9
Step-by-step explanation:
5x - 4 = 41
add
5x = 45
divide
x = 9
Answer:
x = 9
Step-by-step explanation:
First, add 4 to both sides.
5x - 4 + 4 = 5x (+4 and -4 cancel one another out, leaving just 5x)
41 + 4 = 45
So, we get 5x = 45
Divide by 5 on both sides.
5x/5 = x (Again, 5 is cancelled out)
45/5 = 9
We get x = 9

Answer:
43 Degrees
Step-by-step explanation:
(3x + 16) + (6x + 1) + (82) = 180 Degrees
180 - 82 = 98 Degrees
(3x + 16) + (6x + 1) = 9x + 17
9x + 17 = 98
98 - 17 = 81
81 / 9 = 9
x = 9
6(9) + 1 = 55 Degrees
3(9) + 16 = 43 Degrees
55 + 43 + 82 = 180 Degrees

Solve for a.
a + (−5) = 12
Answer:
a = 17
Step-by-step explanation:
a + (-5) = 12
Open the bracket;
a - 5 = 12
Add 5 to both sides
a - 5 + 5 = 12 + 5
Therefore,
a = 17
Answer:
a=17
Step-by-step explanation:
any number plus a negative number is basically subtracting the absolute value of the negative number. so 12 + 5 = 17
A rectangular garden is 5m longer
than it is wide.
The area of the garden is 600m2
Calculate the width and length of the garden.
Answer:
The width of the garden is 22.12 m and its length is 27.12 m
Step-by-step explanation:
Equations
Let x = width of the garden
The length is 5 m longer than the wide, thus:
x + 5 = length of the garden
The area of the rectangular garden is
A=x(x+5)=600
Operating:
[tex]x^2+5x-600=0[/tex]
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Where a=1 b=5 c=-600:
[tex]\displaystyle x=\frac{-5\pm \sqrt{5^2-4(1)(-600)}}{2(1)}[/tex]
Operating:
[tex]\displaystyle x=\frac{-5\pm \sqrt{25+2400}}{2}[/tex]
[tex]\displaystyle x=\frac{-5\pm \sqrt{2425}}{2}[/tex]
There are two solutions:
x = 22.12
x = -27.12
The negative solution is not valid because x is the width of the garden, thus
x = 22.12 m
And
y = 22.12 + 5 = 27.12 m
The width of the garden is 22.12 m and its length is 27.12 m

Match each irrational number line on which it is represented 2.18112... 2.1823912 2.364125 2.1829391321
Answer:
See Explanation
Step-by-step explanation:
The number lines to make selection from are missing from the question.
However, I've attached 4 number lines, each of which represents each of the given irrational numbers (see attachment)
Number: 2.1823912
This is represented by number line 1
Each point of number line 3 is 0.001 units starting from 2.18;
The point which the red dot is located is between 2.182 and 2.183, but the dot is closer to 2.182.
2.1823912 and 2.1829391321 satisfy this property but number line 2 represents 2.1829391321 (see below for explanation)
So: 2.1823912 is represented by number line 1
Number: 2.1829391321
This is represented by number line 2.
Each point of number line 3 is 0.0001 units starting from 2.182;
The point which the red dot is located is between 2.1829 and 2.1830, but the dot is closer to 2.1829.
From the list of given numbers, only 2.1829391321 satisfy this property.
Number: 2.18112...
This is represented by number line 3.
Each point of number line 3 is 0.01 units starting from 2.11;
The point which the red dot is located is between 2.18 and 2.19.
If number lines 1 and 2 represent 2.1823912 and 2.1829391321, respectively, then number line 3 represents 2.18112.
Number: 2.364125
This is represented by number line 4.
Each point on this number line is 0.1 unit starting from 2.0;
The point which the red dot is located is between 2.30 and 2.40. From the list of given numbers, only 2.364125 satisfy this property.
Answer:
1: 2.1823912 2: 2.364125 3: 2.18112 4: 2.18929391321

Its mathematics.
Answer:
The height is 15 cm. The volume is 6000 cm³
Step-by-step explanation:
The base is square, so the sides are equal.
√400 = 20. This is the length and width of the cuboid.
The area of the base and the area of the top face are equal, so we subtract 2(400) from the total area to get the area of the remaining 4 faces.
2000 - 800 = 1200 cm²
Divide by 4 to get the area of an individual face.
1200/4 = 300 cm²
We found the width earlier: 20cm
We found the width earlier: 20cm300/20 = 15cm. This is the height.
To find Volume, multiply Area of the base times the height:
400cm²×15cm = 6000cm³

this is your answer. best of luck.
