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).

D. 175.49
===========================================================
Work Shown:
Because segment GI is parallel to segment TA, this means triangle VGI is similar to triangle VTA.
From that we can set up the proportion
VG/VT = VI/VA
which breaks down into
VG/(VG+GT) = VI/(VI+IA)
Let's plug in the given values. Let x be the length of segment IA.
Let's solve for x
VG/(VG+GT) = VI/(VI+IA)
72/(72+61) = 95/(95+x)
72/133 = 95/(95+x)
72(95+x) = 133*95 ......... cross multiply
6840+72x = 12635
72x = 12635-6840
72x = 5795
x = 5795/72
x = 80.4861111111111 ......... which is approximate
x = 80.49 ......... rounding to the nearest hundredth
The length of IA is roughly 80.49 units. This is not the final answer. The fact that 80.49 is listed as one of the answer choices seems to imply your teacher put it as a trick answer.
Since we found IA = 80.49, this means,
VA = VI + IA
VA = 95 + 80.49
VA = 175.49
This is the length of segment VA, which is the same as segment AV.
-----------------------------
Here's a slightly similar way to solve:
VT = VG+GT = 72+61 = 133
VG/VT = VI/VA
72/133 = 95/x
72x = 133*95
72x = 12635
x = 12635/72
x = 175.486111111111
x = 175.49 is the approximate length of segment AV.

Pleaseee helppp answer correctly !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!
Answer:
let the opposite angle of 44 be x
and let opposite angle of z be y
44+52 + x=180( by sum of all angle is 180°)
96+x=180
x= 180-96
x=84
y+x=180 ( linear pair angle)
y+84=180
y=180-84
y=96
now the y, z,40 are triangle.
y+z+40=180( by sum of all angle)
96+z+40=180
z+136=180
z=180-136
z=44

A ladder is 12 metres long . It leans against a wall with one end on the ground 7 metres from the wall. The other end just reaches a windowsill. Calculate the height of the windowsill above the ground.
i need an explanation please...
Answer:
window sill height =9.75 meters
Step-by-step explanation:
Ladder^2=height^2+length^2
12^2=height^2+7^2
144=height^2+49
height^2=144-49=95
height=9.75

Round 72.178 to the nearest hundredth.
Answer:
72.18
Step-by-step explanation:
The hundreth place is the second to the right of the decimal. So the number in the hundreths place is 72.178. When rounding, you look at the number behind the number you are rounding to. In this case, you want to look at the 8. If the number is 5 or above, you round up. 8 is above 5 so you round the 7 to an 8.
Answer: 72.18

Select the equation and solution for the problem. Let x represent the unknown number.
A total of 15 people on a sports team are riding in 3 vans. How many people are riding in each van if each van is carrying the same number of people?
Answer:
C
Step-by-step explanation:
So your total is 15. There are 3 vans, and we want to know how many are on each van.
3 (number of people on each van)=15
Number of people are unknown
3x=15
Divide both sides by 3 to solve for x
x=5

Find the value of x so that f(x)=3
Answer:
f(x) = (1/3)x - 2
f(x) = (1/3)(3) - 2

Four positive whole numbers add up to 39 one of the numbers are a multiple of 7 the other three are equal workout the result when the four numbers are multiplied
Answer:
Number is 4536
Step-by-step explanation:
Assume;
Same number = a
Multiply of 7 = b
So,
a+a+a+b = 39
3a + b = 39
Use b = 7
3a + b = 39
3a + 7 = 39 (Not possible)
Use b = 14
3a + b = 39
3a + 14 = 39 (Not possible)
Use b = 21
3a + b = 39
3a + 21 = 39
a = 6
So,
Number is 6 x 6 x 6 x 21
Number is 4536

Each square is one square unit. Sienna uses the same square units to draw a 6 x 2 rectangle and says that it has the same area as the 3 x 4 rectangle. Is she correct?
Answer:
Yes, Sienna is correct because 6 times 2 is 12 and 3 times 4 is 12.
Deborah spent $70 on food and clothes. She spent $26 more on clothes than on food. On your worksheet, solve the question and write your answer below. How much did she spend on food and how much did she spend on clothes?
Answer:
She spent $22 on food, and $48 on clothes.
Step-by-step explanation:
Let's define the variables:
C = amount of money that Deborah spent on clothes
F = amount of money that Deborah spent on food.
We know that she spent in total $70, then we have the equation:
F + C = $70
And we know that she spent $26 more on clothes than on food, then we have the equation:
C = F + $26
This means that we have a system of equations:
F + C = $70
C = F + $26
To solve these type of systems, we usually start by isolating one variable in one of the equations. Here we can see that C is already isolated in the second equation.
Now we can replace it in the first equation.
F + (F + $26) = $70
Now we can solve this for F.
2*F + $26 = $70
2*F = $70 - $26 = $44
F = $44/2 = $22
So she spent $22 on food.
Now we can use the equation:
C = F + $26
To find how much she spent on clothes, where we need to replace F by the value we found.
C = $22 + $26 = $48
She spent $48 on clothes.
2. Emma knows that her mix of 5 cups of orange juice to 2 cups of ginger
ale will create enough drink for 7 people. If she is looking to create
enough drinks for 28 people, how many cups of orange juice will she
need? *
Answer:
11 1 /2 ( 11 and a half)
Step-by-step explanation:
If you noticed 7 and 2 are five numbers away.
To solve this I just added one to both of them until the sum was equal to 28.
If I had added one to 16 and 11, it would have given me 29, so I added a half.
That gave me 28.
A farmer has just tilled her 51-yard by 68-yard field. To survey her field, the farmer begins in one corner and walks the length of the field. She then turns and walks the width before crossing diagonally across the field to the original corner. How far does the farmer walk?
Answer: l +w+ hypotenuse or 204
Step-by-step explanation: so the farmer walks the length then the width of the field then the diagonal which we don't know using pythagorean to find that last side then add the values 51^2+68^2=c^2 and 51+68+85= 204

Answer:
CD = 4
Step-by-step explanation:
I believe you know the geometric mean for altitudes?
CD = √AD * DB = √8 * 2 = √16 = 4
If you are not aware of this theorem, then use the similarity of triangles.
ADC ~ CDB
AD/DC = CD/DB (cross-multiply)
CD^2 = AD*DB,
CD = √AD * DB = √8 * 2 = √16 = 4
Find the measurement of angle ABC
Answer:
x=97° a=97° b=97°
Step-by-step explanation:
83°+a=180° (by linear pair)
a=180°- 83°
a=97
and a=x°(by corresponding angle)
x= 97°
x=b(by vertical opposite angle)
b = 97°
