What is simultaneous linear equation?Simultaneous linear equations are the system of two linear equations in two or three variables that are solved together to find a common solution.
A system of simultaneous linear equations is any set of two or more linear equations that share the same unknown variables. Finding values for the unknown variables that simultaneously satisfy all of the equations is required to solve such a system.
Two linear equations in two variables together are known as simultaneous linear equations.
The solution of the system of simultaneous linear equations is the ordered pair (x, y) that satisfies both linear equations.
Based on the given conditions,
Equation P: y + z = 6 ( Equation-1 )
Equation Q: 8y + 7z = 1 ( Equation-2 )
To solve the above simultaneous linear equation multiply the equation-1 with (-8)
So,
We can write,
⇒ ( y + z = 6 ) * (-8)
-8y - 8z = -48 ( Equation-3 )
Now add Equation (3) with Equation (2)
Then,
-8y - 8z = -48
8y + 7z = 1
----------------------------
-z = -47
z = 47
Therefore,
The expression ( y + z = 6 ) * (-8) is a possible step used in eliminating the y-term.

Giorgio fills up his car which is 60 liters.
After a certain distance, 340 deciliters remained in the tank.
How many liters did it consume?
How much did you spend if 1 liter costs € 1.45? How many liters of petrol can you buy for € 58?
My book has the answer but not step by step explanation
[ 26 liters; €37,70; 40 liters ]
The amount of litres he consume is 26 litres.
He spent a total of €37,70 for 26 litres.
He can buy 40 litres of petrol for € 58
How to find the number of litres the car consume and the cost?He fills up his car which is 60 litres.
After a certain distance, 340 decilitres remained in the tank.
Therefore, we have to convert the amount of gas remaining in the car to litres.
Hence,
1 decilitres = 0.1 litres
340 decilitres = ?
cross multiply
amount of petrol remaining in the car = 0.1 × 340
amount of petrol remaining in the car = 34 litres
Therefore,
amount of litres consumed = 60 - 34 = 26 litres.
Let's find the cost he spent if 1 litre cost € 1.45.
1 litre = € 1.45
26 litres = ?
amount spent = 26 × 1.45
amount spent = € 37.70
Let's find how many litres of petrol he can buy for € 58.
€ 1.45 = 1 litre
€ 58 = ?
cross multiply
number of litres he can buy with € 58 = 58 / 1.45
Therefore,
number of litres he can buy with € 58 = 40 litres.

1. Reject the null.
2. Data is consistent with the null hypothesis.
3. Unable to tell using our staff confidence interval.
What are confidence interval?A confidence interval in frequentist statistics is a range of estimates for an unknown parameter. A confidence interval is calculated at a specified degree of confidence; the most popular level is 95%, but other levels, such 90% or 99%, are occasionally used. Confidence intervals are used by statisticians to assess a sample variable's level of uncertainty. For instance, a researcher might randomly select many samples from the same population, compute a confidence interval for each sample, and then examine how well each sample might reflect the true value of the population variable. The generated datasets are all unique, some of which contain the genuine population parameter and others which do not. An unknown population parameter is most likely to be found inside a range of values that is bounded above and below the statistic's mean.

In triangle ABC, let the angle bisectors be BY and CZ. Given AB = 8, AY = 6, and CY = 3, find BZ.
The length of the segment BZ is approximately 2.78
The above value is obtained by using the following process:
The given parameters of the triangle are;
The angle bisectors of the triangle = BY and CZ
The point at which BY and CZ meet = The point I
The length of CY = 4
The length of AY = 6
The length of AB = 8
The unknown parameter;
The length of the segment BZ
Method:
Apply the angle bisector theorem
According to the angle bisector theorem we have;
AY/CY = AB/BC
BZ/AZ = BC/AC
From AY/CY = AB/BC, we get;
6/4 = 8/BC
6 × BC = 8 × 4 = 32
BC = 32/6 = 16/3 = 5.33
BC = 5.33
From BZ/AZ = BC/AC, we have;
AC = CY + AY
∴ AC = 4 + 6 = 10
AZ = AB - BZ
∴ AZ = 8 - BZ
Therefore;
BZ/8 - BZ = 5.33/10
10 × BZ = ×(8 - BZ) = (16/3) × 8 - (16/3)·BZ
10·BZ + (16/3)·BZ = (16/3) × 8
(46/3)·BZ = 128/3
BZ = 128/46 = 64/23
Length of the line BZ = 64/23 = 2 ≈ 2.78
Therefore, the length of the segment BZ is approximately 2.78.

The measure of the angle indicated is as follows:
m∠S = 39°How to find angles?The measure of the angle indicated can be found using exterior angle theorem. The exterior angle theorem states that If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.
Therefore,
m∠S + m∠T = 129
m∠S = -3 + 6x
m∠T = 11x + 13
Therefore,
129 = - 3 + 6x + 11x + 13
129 = - 3 + 13 + 6x + 11x
129 = 10 + 17x
129 - 10 = 17x
119 = 17x
x = 119 / 17
x = 7
Therefore,
