Nasim is taking a multiple choice test with a total of 50 points available. Each
question is worth exactly 2 points. What would be Nasim's test score (out of 50) if he
got 5 questions wrong? What would be his score if he got x questions wrong?
Score with 5 questions wrong:
Score with a questions wrong:
Pls help fast 80 points
Answer:
Score with 5 questions wrong = 40 points
x questions wrong = 50 - 2x points
Score with a question wrong = 48 points
Step-by-step explanation:
Total points = 50 points
Points per question = 2 points
Number of questions = Total points / Points per question
= 50/2
= 25 questions
What would be Nasim's test score (out of 50) if he got 5 questions wrong
= Total points - 5 questions * 2 points
= 50 - 5(2)
= 50 - 10
= 40 points
Score with 5 questions wrong = 40 points
What would be his score if he got x questions wrong?
= Total points - x questions * 2 points
= 50 - x(2)
= 50 - 2x
Where x = number of questions
x questions wrong = 50 - 2x points
Score with a question wrong
= Total points - 1 questions * 2 points
= 50 - 1(2)
= 50 - 2
= 48 points
Score with a question wrong = 48 points
Answer----=X
I dont know the process
answer = x
Step-by-step explanation:
x over 2 + x over 2
(x+x)/2 = (2x)/2
0 = (2x)/2
move 2 beside 0
2 = 2x
move 2 to left
when 2 in right side is positive, if it moves to left it will be negative, then it will be,
2-2 = x
= x #

Divide using long division.
(2x2 + 7x + 6) : (x + 2)
Answer:
2x+3
Step-by-step explanation:
-2x2 - 7x - 6
--------------------
-x-2
-2x2 - 7x - 6 = -1 • (2x2 + 7x + 6)
-x - 2 = -1 • (x + 2)
2x2 + 7x + 6
x • (2x+3) and (x+2) • (2x+3)
answer- 2x+3
Multipy first : 2 x 2 = 4
7x + 6, x is the variuable and x + 2
Take x out of both u have = 7 + 6 : 2 (x + x) = x
4 + (7 + 6), 7 + 6 = 13
13 + 4 = 17
17 + 2 = 19x

Step-by-step explanation:
Answer:
2( x +2 )
x+1
Step-by-step explanation:
to add or subtract expressions expand them to make their denominators the same, multiply 1 time [tex]\frac{x-2}{x-2}[/tex]
since [tex]\frac{x}{x-2}[/tex] and [tex]\frac{x-2}{x-2}[/tex] have the same denominators add them by adding their numerators
combine x + x -2
factor [tex]x^{2}[/tex] - 4
to add or subtract expressions expand them and multiply by 1
have same denominator add them by adding their numerators
do the multiplications in 3 + ( x-2 )(x+2)
combine like terms in 3 + [tex]x^{2}[/tex] + 2x - 2x -4
divide [tex]\frac{2x-2}{x-2}[/tex] by [tex]\frac{-1 + x^{2} }{(x-2)(x+2) }[/tex] multiplying [tex]\frac{2x-2}{x-2}[/tex]
cancel out x-2 in both numerator and denominator
factor the expression that are not already factored
cancel out x-1 in both numerator and denominator
expand the expression

Answer:
6
Step-by-step explanation:
Ok, so all we have to do is multiply 8 * 3/4, because each child needs 3/4 of the sandwich, and there are 8 of them. The easiest (My opinion) way to do this is by turning 8 into a fraction. Turning whole numbers into fractions is really simple, just slap a /1 under them to make them a fraction. And so, our fraction is 8/1. Now, all we have to do is multiply the top part of the fraction, and then the bottom part of the fraction. So, 8 * 3 = 24, and 1 * 4 = 4. So, just put 24/4 as an answer. But, wait! We have to simplify it! 24 divided by 4 is 6, so 6 is our final answer.
What is the proportion of 36 / x equals 8/7
Answer:
Step-by-step explanation:
Multiply all terms by the same value to eliminate fraction denominators
36/x=8/7
x times 36/x=x times 8/7
Cancel multiplied terms that are in the denominator
cancel both x’s for you should have 36=x times 8/7
Combine multiplied terms into a single fraction
36=8x/7
Multiply all terms by the same value to eliminate fraction denominators
36=8x/7 so you multiply 7 times 36=7 times 8x/7
so you simplify so you get 252=8x
then you Divide both sides of the equation by the same term
252=8x 252/8=8x/8 so you get 63/2
so your final answer is x=63/2

Thor and Rusty bought snacks for a party. Thor bought 4 bags of chips and 3 bottles of soda for $10.52. Rusty bought 3 bags of chips and 2 bottles of soda for $7.61. How much did the bags of chips each cost? How much did the bottles of soda each cost?
Answer:
Chips= $1.79
Soda= $1.12
Answer:
chips: $1.79
soda: $1.12
Step-by-step explanation:
x = chips cost
y = soda cost
4x + 3y = 10.52
3x + 2y = 7.61
i used the elimination method by multiplying the first equation by -2
and the second equation by 3
-8x - 6y = 21.04
9x + 6y = 22.83
x = 1.79
solve for 'y':
3(1.79) + 2y = 7.61
5.37 + 2y = 7.61
2y = 2.24
y = 1.12

Step-by-step explanation:
step 1. ABCD is an isosceles trapezoid because AD and BC are parallel, AB and CD are congruent
step 2. x = 56° (definition of an isosceles trapezoid)
step 3. x + y + z + 56 = 360 (definition of a quadrilateral)
step 4. y = z (definition of an isosceles trapezoid)
step 5. 56 + 2y + 56 = 360
step 6. 2y = 248

A fence is to be enclosed around a square park of side 15m. Atleast how many metres of fencing are needed?
Answer: 60 m
Step-by-step explanation:
The park is said to be square which means that all of its sides are equal.
If the fence is supposed to be put around the park, it is an indirect question asking for the perimeter of the square.
Perimeter of a square:
= 4 * length
= 4 * 15
= 60 m

Need to find measure of m, p
Step-by-step explanation:
2p-5=p+5
p=10°
2m=10
m=5
Answer:
m = 5
p = 10
Step-by-step explanation:
In triangle HIJ,
IH = IJ.. (given)
Therefore,
2m = 10
m = 10/2
m = 5
IK is angle bisector of triangle HIJ.
So,
(2p - 5)° = (p = 5)°
2p - 5 = p + 5
2p - p = 5 + 5
p = 10
