Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
Question 2: The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
Answer: x=14
only #2
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
2x+6−3x=3x−8−3x
−x+6=−8
Step 2: Subtract 6 from both sides.
−x+6−6=−8−6
−x=−14
Step 3: Divide both sides by -1.
-x/-1=-14/-1

Solve for the value of w.
(w-8)°
(2W-1)º
Answers
Answer:
w=57
Step-by-step explanation:
The angles are supplementary because they are adjacent to one another and lies on a straight line
w-8+2w-1=180
Combine like terms
3w-9=180
Subtract 9 on both sides
3w=171
Divide 3 on both sides
w=57

if angle 1= 135, what is the measure of angle 2, and give your reason. Use the picture i used
Answers
Answer:
The measure of m∠2 is:
m∠2 = 45°Step-by-step explanation:
A straight angle is an angle equal to 180 degrees. It is called straight because it appears as a straight line.
Given
The angle ∠ 1 = 135°.
It is clear that angles ∠ 1 and ∠ 2 lie on a straight line.
We know that a straight line is basically a straight angle i.e. 180°.
Thus,
The sum of angles ∠ 1 and ∠ 2 will be 180°.
i.e.
m∠1 + m∠2 = 180°
substitute m∠1 = 135° in the equation
135° + m∠2 = 180°
subtract 135° from both sides
135° + m∠2 - 135° = 180° - 135°
m∠2 = 45°
Therefore, the measure of m∠2 is:
m∠2 = 45°A farm has 140 bushels of wheat to sell at his roadside stand .He sells an average of 15 ⅗ blushes each day. Represent the total change in the number of blushes he has sold after 6 days.
Answers
Answer:
93 3/5
Step-by-step explanation:
Total bushels to sell = 140
Average sale per day = 15 3/5 bushels
Total change in the number of bushels sold after 6 days ;
Average bushels sold per day * Number of days
15 3/5 * 6
(78/ 5) * 6
468 / 5
= 93 3/5
Change in number sold after 6 days = 93 3/5
The scatterplot below shows the number of hours that some high school students spend on working and on video games.
A graph title Working and Video games has weekly working hours on the x-axis and weekly hours of video games on the y-axis. Points are grouped together and decrease.
Which statement about the scatterplot is true?
In general, the number of hours spent working does not affect the number of hours spent on video games.
In general, the amount of weekly time spent working is equal to the amount of weekly time spent on video games.
As the amount of time spent working increases, the amount of time spent on video games increases.
As the number of hours spent working increases, the amount of time spent on video games decreases.

Write down in terms of n,an expression for the Nth term of the following sequences.
A) 2,5,8,11,14
B) 9,11,13,15,17
Answers
Answer:
see explanation
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
A
There is a common difference d between consecutive terms , that is
d = 5 - 2 = 8 - 5 = 11 - 8 = 14 - 11 = 3
Thus the sequence is arithmetic with a₁ = 2 and d = 3, then
[tex]a_{n}[/tex] = 2 + 3(n - 1) = 2 + 3n - 3 = 3n - 1
[tex]a_{n}[/tex] = 3n - 1
B
There is a common difference d between consecutive terms , that is
d = 11 - 9 = 13 - 11 = 15 - 13 = 17 - 15 = 2
Thus the sequence is arithmetic with a₁ = 9 and d = 2 , then
[tex]a_{n}[/tex] = 9 + 2(n - 1) = 9 + 2n - 2 = 2n + 7
[tex]a_{n}[/tex] = 2n + 7
Answer:
so for question a the ans is 3n-1
for question b the ans is 2n+7
Step-by-step explanation:
Question Ausing the formula for arithmetic progressikn(a.p) a +(n-1)d, u use this formula because it has a common differnce
a=2, where a is first term or t1
d=t2-t1=5-2=3m where d is common difference
replace the values in the formula
2+(n-1)3
2+3n-3
3n-3+2
3n-1, this is the formula for the nth term
it will be 3n -1
if u try it
3(1)-1=2
3(2)-1=5
3(3)-1=8
3(4)-1=11
3(5)-1=14
Question B
using the formula for a.p, a+(n-1)d
a=9, because it is the first term
d=t2-t1=11-9=2
replace the values in the formula
9+(n-1)2
9+2n-2
2n+9-2
2n +7,this is the formula for the7th term
if u try it
2(1)+7=9
2(2)+7=11
2(3)+7=13
2(4)+7=15
2(5)+7=17

Given function:
C(x) = 30x
Where,
x = number of students
A. 20
C(x) = 30x
20 = 30x
x = 20/30
= 0.67
x = 0.67 student
B. 30
C(x) = 30x
30 = 30x
x = 30/30
x = 1 student

4 bonbons and 3 nougats
What fraction are carame/s
b. What fraction are not caramels?
Answers
Answer:
3/10 are caramel 7/10 are not caramel
Step-by-step explanation:
First you need to work out the total of sweets that is 6+7+4+3=20 sweets. Now it says that there are 6 caramels so you need to put 6/20 which can be simplified to 3/10. For b you have to work out the fraction that is not caramel so for this you have to add up 7+4+3=14 put 14/20 this can be simplified to 7/10.

WILL GIVE BRAINLIEST! Six numbers form an arithmetic sequence with a common difference of 4. The sum of these numbers equals to 12. What are the six numbers?
Answers
Answer: -8,-4,0,4,8,12
Step-by-step explanation:
The six numbers of the arithmetic progression are -8, -4, 0, 4, 8, 12
Arithmetic sequence:aₙ = a + (n - 1)dwhere
a = first term
d = common difference
n = number of terms
d = 4
first term = a
2nd term = a + 4
3rd term = a + (3 - 1) 4 = a + 8
4th term = a + (4 - 1) 4 = a + 12
5th term = a + (5 - 1) 4 = a + 16
6th term = a + (6 - 1) 4 = a + 20
sum of its 6 terms = 12
Therefore,
a + a + 4 + a + 8 + a + 12 + a + 16 + a + 20 = 12
6a + 60 = 12
6a = 12 - 60
6a = -48
a = -48/6
a = -8
2nd term = -8 + 4 = -4
3rd term = -8 + 8 = 0
4th term = -8 + 12 = 4
5th term = -8 + 16 = 8
6th term = -8 + 20 = 12
