In a class test , 3 marks are awarded for every correct answer and (-2) marks are awarded for every incorrect answer and no marks for not attempting any questions. ( find the following given below ).
1) Irine scored 20 marks . if she has got 12 correct answers , how many questions has she attempted incorrectly ?
2) Chloe scored (-5) though she has got 7 correct answers . how many questions has she attempted not correctly ?
[tex]\huge\sf {solution}[/tex]
#1 Marks awarded for onecorrect answers = 3 Marks awarded for 12 correct answers = 3 × 12 = 36 Marks obtained for incorrect answers = 20 - 36 = -16 Marks given for 1 incorrect answer = -2 Therefore, ( - 16 ) ÷ ( - 2 ) = 8hence , irene has attempted 8 questions incorrectly
#2 Marks scored by chloe for 7 correct answers = 3 × 7 = 21 chloe scored = -5 Marks obtained for incorrect answers = -5 - 21 = -26 Marks awarded for 1 incorrect answer = -2 Therefore , number of incorrect answer = -26 / -2 = 13hence , chloe has attempted 13 questions not correctly

In △QRS , ∠R is a right angle and the measure of ∠S is 22° .
(image below)
Which equation can be used to calculate the measure of ∠Q ?
A
x+22=180
B
x+22=90
C
22−x=180
D
22−x=90
Answer:
i think the answer is b
because,
if x+22=90
x=90-22=68
we know that the sum of the three angles of a triangle is 180
so, that means
90+22+68 should be 180
and it is 180, so the answer must be b

Fred is an old man he lived 1\8 of his life as a boy, 1\12 as a youth, 1\2 as a man and 28 years in his old age. How old is Fred now
1. Observe problem
1-(1/8+1/12+1/2)
Make all common denominator
The Least common multiple of 8,12, and 2 is 24
1-((3+2+12)/24)=
1-17/24=
7/24
Therefore, 28 years make up 7/24 of his life.
Simplifying, he grows 4 years for every 1/24 of his life
4 times 24 is 96, so
Fred is 96 currently(that's pretty old)
[tex]\bold{\huge{\pink{\underline{ Solution }}}}[/tex]
[tex]\bold{\underline{ Given :- }}[/tex]

We have to find the current age of Fred?[tex]\bold{\underline{ Let's \: Begin :- }}[/tex]
Let the present age of Fred be x
Therefore,
According to the question,
[tex]\sf{ 1/8x + 1/12x + 1/2x + 28 = x }[/tex]
[tex]\sf{ (3x + 2x + 12x )/24 + 28 = x }[/tex]
[tex]\sf{ 17x/24 + 28 = x }[/tex]
[tex]\sf{ 28 = x - (17/24)x}[/tex]
[tex]\sf{ 28 = 24x - 17x/24 }[/tex]
[tex]\sf{28 = 7x/24 }[/tex]
[tex]\sf{ 28 = 7x/24}[/tex]

Find the slope of the line that passes through G(−3, 2) and H(7, 2).
PLEASE I DONT HAVE TIME I BEG U
The solution is, the slope of the line that passes through G(−3, 2) and
H(7, 2) is 0.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
given that,
G(−3, 2) and H(7, 2).
now, we have to find, the slope of the line that passes through G(−3, 2) and H(7, 2).
now, we know that,
Slope = (y2-y1) / (x2-x1)
here,
G(-3,2) = (x1,y1)
H(7,2) = (x2,y2)
Substitute these values to find the slope.
Slope = (2-2)/(7-(-3))
= 0/10
= 0
Hence, The solution is, the slope of the line that passes through G(−3, 2) and H(7, 2) is 0.

Trying to get my grade up
Answer: x=4 and y=1
Step-by-step explanation:
From the first equation, we get y = 9 - 2x. Substitute this into the second equation we get
3x - 4(9 - 2x) = 8
3x - 36 + 8x = 8
11x = 44
x = 4
y = 9 - 2(4)
y = 1

A rectangle has a width of 12. 5 m and a length of 105 m. What is the effect on the perimeter when the dimensions are multiplied by 2? The perimeter is increased by a factor of 2. The perimeter is increased by a factor of 21. The perimeter is increased by a factor of 25. The perimeter is increased by a factor of 92.
The perimeter of the rectangle is got increased by a factor of 2. The correct option is A.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In rectangle opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at mid-point.
Given
A rectangle has a width of 12.5 m and a length of 105 m.
We know the perimeter of the rectangle is given by
Perimeter = 2 (Lenght + Width)
Let x be the length and y be the width. Then
Perimeter = 2 (x + y)
If the dimensions are multiplied by 2. Then the effect on the perimeter will be
Perimeter = 2 (2x + 2y)
Perimeter = 2 [2 (x + y)]
The perimeter is increased by a factor of 2.
Thus, option A is correct.

which statement best explain best explains whether the table represents a linear or non linear function (100 POINTS) HURRYYYY PLSSS
Answer:
It is a linear function because there is a constant rate of change in both the input and output values
Step-by-step explanation:
To determine if the function is linear, calculate the differences between the y values.
If the differences are constant, or the same value, the equation is linear and has a constant slope. If the differences are not the same, the equation is not linear.
difference between y values (output)
7 - 4 = 3
3 - 1 = 3
1 - -2 = 3
⇒ the function is linear
difference between x values (input)
-2 - -5 = 3
-5 - -8 = 3
-8 - -11 = 3
⇒ the function is linear as there is a constant rate of change in both the input and output values

What is the equation of the line that passes through the point (−8,−7) and has a slope of 1?
Answer:
y = x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 1 , then
y = x + c ← is the partial equation
To find c substitute (- 8, - 7 ) into the partial equation
- 7 = - 8 + c ⇒ c = - 7 + 8 = 1
y = x + 1 ← equation of line
