Answer:
3
Step-by-step explanation:
1st step: (6-5) = 1; you now have:
[4 - 5 - 7(1) + 7)] + 4
2nd step: 7(1) = 7; you now have:
[4 - (5 - 7 + 7)] + 4
3rd step: 5 - 7 + 7 = 5; you now have:
[4 - 5] + 4, which is (-1 + 4) which equals 3

Answer:
7. x = 5
8. x = 2, y = 6
9. x = 21, y = 39
Step-by-step explanation:
For a parallelogram, the lengths across intersection are equal.
7. For a parallelogram, the lengths across intersection are equal.
So that,
3x = 4x - 5
4x - 3x = 5
x = 5
8. For a parallelogram, the lengths across intersection are equal.
So that,
2x = 4
x = [tex]\frac{4}{2}[/tex]
x = 2
and
y - 1 = 2y -7
7 - 1 = 2y - y
y = 6
x = 2, y = 6
9. For a parallelogram, opposite angles have equal value.
Thus,
3x = (4x - 21)
3x = 4x - 21
x = 21
and
3y = (y + 78)
3y = y + 78
3y - y = 78
2y = 78
y = [tex]\frac{78}{2}[/tex]
= 39
y = 39
x = 21, y = 39
Mr. Martin and his son, Luke, decide to walk a 12
kilometer trail. Mr. Martin takes a 1-hour head start and
walks at a pace of 3 km/hr. Explain how fast Luke should
walk to reach the end of the trail in 3 hours, the same time
as Mr. Martin.
Answer:
4km/h
Step-by-step explanation:
we have the dad walking 3 km per hour but he had a headstart menaing he has 4 hours to do it, 3 times 4 is 12. now we have the son doing 12 kilometers in 3 hours so we divide 12 by 3 meaning he has to be going at a pace of 4 km per hour.
Answer:
It will take Mr. Martin 4 hours to walk the trail, and Luke should walk faster than Mr. Martin. Using the equation 12 = (3)(x), Luke should walk 4 km/hr to finish the trail in 3 hours.

Please help me find the value of x the answer must be exact
Answer:
[tex]x=11[/tex]
Step-by-step explanation:
This is a 45°-45°-90° triangle. The two legs are the same length, and the hypotenuse is that length times the square root of two:
[tex]leg=x\\hypotenuse=x\sqrt{2}[/tex]
Therefore, the value of x is 11.
You can double-check using the sine ratio:
[tex]sineX=\frac{opposite}{hypotenuse}[/tex]
Insert the values:
[tex]sin45=\frac{x}{11\sqrt{2} }[/tex]
Insert the equation into a calculator:
[tex]x=11[/tex]
:Done
*It's important to know that, when working with trigonometry ratios, the hypotenuse is never considered the adjacent or opposite side, and the 90° angle is never used in the ratios.

The marked price of a watch is Rs.2700. If the percentage of discount given on marked price is twice of the percentage of VAT and the value of the watch after adding VAT is Rs.2376.Find the rate of VAT
Answer:
24%
Step-by-step explanation:
Step one:
given data
The marked price of a watch is Rs.2700
The value of the watch after adding VAT is Rs.2376
let us find the discount
= 2700-2376
=324
then the percentage discount is
=324/2700*100
=0.12*100
=12%
The VAT is twice the discount, the VAT is 12*2= 24%

Answer:
1. x= -20
2. x= 6.33
Step-by-step explanation:
Question 1:
10=7
x=x+6
(Cross multiply)
10(x+6)=7x
10x+60=7x
10x-7x=-60
3x=-60
x=-60/3= -20
Question 2:
6=4
8=x-1
(Cross multiply)
6(x-1)=4×8
6x-6=32
6x=32+6
6x=38
x= 6.33

1. What is the slope of a line that is perpendicular to the x-axis
Answer:
The slope of a line that is perpendicular to the x-axis is undefined.
Step-by-step explanation:
We know that the x-axis is a horizontal line.
We also know a line that is perpendicular to the x-axis is basically a vertical line.As the slope of a perpendicular line is undefined because no matter what the value of y is, the x-value remains the same.Therefore, the slope of a line that is perpendicular to the x-axis is undefined.
For example, the slope between (1, 2) and (1, 4) is:
Using the slope formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [1 - 1]
= 2 / 0
= ∞

To factor a[tex]x^{2}[/tex]+bx+c, you have to group it as (a[tex]x^{2}[/tex]+ux)+(vx+c) so that uv=ac and u+v=b. Both addition and multiplication are commutative, so how do you determine which value is assigned to u and which to v? Or are they interchangeable?
For example, let's expand out (x+3)*(2x+1). Use of the FOIL rule should get to you 2x^2 + 7x + 3.
Now imaging that you handed 2x^2 + 7x + 3 to a friend to be factored. They do not know the factorization yet.
They would see that a = 2, b = 7, c = 3.
The friend needs to find two numbers u,v such that they multiply to a*c = 2*3 = 6 and add to b = 7
Through trial and error (I recommend making a table of values), your friend would get
u*v = 1*6 = 6u+v = 1+6 = 7But as you mentioned, your friend could easily swap the order of addition and multiplication to say
u*v = 6*1 = 6u+v = 6+1 = 7----------------------
If we go with the first option, then the factor by grouping looks like this
2x^2 + 7x + 3
2x^2 + 1x + 6x + 3 ... break up 7x into 1x+6x
(2x^2+1x) + (6x+3) .... group up the terms into pairs
x(2x+1) + 3(2x+1) .... factor each grouping
(x+3)(2x+1) ..... factor out the overall GCF
---------------------
Or we could have the factor by grouping looks like this
2x^2 + 7x + 3
2x^2 + 6x + 1x + 3 ... break up 7x as 6x+1x
(2x^2+6x) + (1x+3)
2x(x+3) + 1(x+3)
(2x+1)(x+3)
(x+3)(2x+1)
We end up with the same factorization.

Suppose that 8 machines can complete a certain task in 9 days. if there are 18 machines, how many days would it take for them to finish the same task?
Answer:
It would require 4 days.
If there are 18 machines. Then the number of days would it take for them to finish the same task will be 4 days.
What is Algebra?Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
Time is inversely proportional to the number of the machines.
T ∝ 1/M
If the proportionality is removed, then a constant k is introduced.
Suppose that 8 machines can complete a certain task in 9 days.
Then the amount of the total work that is k will be
k = 8 x 9
k = 72
If there are 18 machines.
Then the number of days would it take for them to finish the same task will be
T = 72 / 18
T = 4 days
The number of days would it take for them to finish the same task will be 4 days.
