Answer:
A.Both of the students did the problem correctly.
Step-by-step explanation:
B. Nikki multiplied the fraction(8/3) to the items in the parentheses. Then multiplied each side with 3. Jon did the opposite. He first removed the fraction by multiplying each side by 3. Then he multiplied 2 to the items in the paranthesis.
C. I prefer Jon's method. Fractions can be tricky. I prefer to remove them as soon as possible. This time the items in the paranthesis had whole numbers. But had any of them been a fraction too, the problem would have gotten a lot more tricky and it would very easy to make a mistake or miscalculate something.

Solve the equation. 6g = 48 what does g equal?
Answer:
8
Step-by-step explanation:
First we need to figure out what g equals
Since 6 x 8 = 48 your answer would be 8
6 x 8 = 48
~ LadyBrain
The value of g that satisfies the equation is 8.
To solve the equation 6g = 48 and find the value of g, we can isolate the variable g by dividing both sides of the equation by 6:
6g / 6 = 48 / 6
This simplifies to:
g = 8
Therefore, g equals 8. By dividing both sides of the equation by 6, we find that when g is multiplied by 6, it results in 48. Hence, the value of g that satisfies the equation is 8.

Identify each situation as a permutation or a combination.
1. choosing friends to invite to a party
2. choosing your top 10 favorite actors
Answer:
1. Combination
2. Permutation
Step-by-step explanation:
Permutations occur in cases where the order of something changes the arrangement (e.g. Choosing letters of a password). Combinations occur when the order of something does not matter (e.g. choosing three donut flavors).
1. Since the order of which you choose and invite your friends does not change who you've invited, this is a combination (order does not matter).
2. When ranking a top-10 list, the order of your ranking affects the ranking itself and makes a difference (order matters). Therefore, this situation is a permutation.
Find QR.
PLEASE HELP!!!
Answer:
B.6
Step-by-step explanation:
3 + 2x + 22 = x + 17
Combine like terms
25 + 2x = x + 17
Subtract 17 from both sides
8 + 2x = x
Subtract 2x from both sides
8 = -x
Divide both sides by -1
x = -8
Substitute -8 for x in 2x + 22 to find value of QR
2(-8) + 22
Multiply
-16 + 22
Add
QR = 6
The length of QR in the given figure by combining like terms and applying the substitution method, QR = 6
Used the concept of addition and combining like terms in the mathmatical expression.
Given that,
The length of line segments is,
PQ = 3
QR = (2x + 22)
PR = (x + 17)
Now, from the figure,
PQ = QP + QR
Substitute the given values,
x + 17 = 3 + 2x + 22
Combine like terms
x + 17 = 25 + 2x
Subtract 17 from both sides
x = 8 + 2x
Subtract 2x from both sides
x - 2x = 8
- x = 8
Divide both sides by -1
x = -8
So, for the length of QR,
Substitute - 8 for x in the length of QR,
QR = 2x + 22
= 2(-8) + 22
= -16 + 22
= 6

What is the value of x?
26°
オー
X=
[?]
Enter
Answer:
154 degrees
Step-by-step explanation:
A quadrilateral has the sum of the interior angles that is 360 degrees
for the tangent theorem we know that the angles where the lines intercept the circumference have a value of 90 degrees
x + 90 + 90 + 26 = 360
x + 206 = 360
x = 360 - 206
x = 154 degrees
A regular polygon with exterior angle of 45° is redrawn using a scale 1 : 5. If the actual length of the sides of the regular polygon is 10cm, calculate the perimeter of the scale drawing of the regular polygon.
Answer:
16 cm
Step-by-step explanation:
"regular polygon" means all sides and angles are the same.
the sum of all exterior angles must be 360 degrees.
so, how often do 45 fit into 360 ?
2 times in 90, which in turn fit 4 times into 360, so 8 times.
the polygon has 8 corners and 8 sides.
each side is originally 10cm
so the original perimeter is 8×10 = 80 cm
now, every side is reduced to 1/5th of the original size, this also reduces the perimeter by the same factor.
=> perimeter = 80×(1/5) = 80/5 = 16 x cm
control :
applying the scaling factor of 1/5th to every side transforms every side from 10 cm to 2 cm.
we still have 8 sides.
perimeter = 8 × 2 = 16 cm

x² = 225
x = 15
Find the Area:
1/2(8 x 15) = Area
1/2(120) = Area

a = 5, b = -2, c = 6
= [2 ± √(-2²)-4(5)(6)] ÷ 2(5)
= (2 ± √4-120) / 10

The equation of the line of best fit of a scatter plot is y = −8x + 3. What is the the y-intercept?
A. −8
B. −3
C. 3
D. 8
Answer:
C. 3
Step-by-step explanation:
The y intercept will always be the 'b' in the formula
y= mx+b
since your formula is y = -8x +3, and 3 is in the place of "b", your y intercept will be 3
Answer:
C.3
Step-by-step explanation:
In the equation of y = -8x +3 you can find the y - intercept by looking at number which replaces b which is a positve three. Meaning that your y - intercept would be answer choice C which is positive three.

(7x + 10y = 11
(4x + 3y = -10
Answer:
x=-7
y=6
Step-by-step explanation:
7x+10y=11
4x+3y=-10
-3(7x+10y=11
10(4x+3y=-10
-21x-30y=-33
40x+30y=-100
19x = -133 (divide 19 on both sides)
x= -7
Now put the x in one of the original questions.
7(-7)+10y=11
-49+10y=11 (Add 49 to both sides)
10y=60 (Divide 10 on both sides)
