Answer:
6 favors each guest
Step-by-step explanation:
3 bag if 12 means total 36
She has divided evenly amongst 6 guest .
36/6 = 6each guest.
Answer:
The answer would be 6.
Step-by-step explanation:
Assuming, Amy doesn't have a sweet tooth, she's only giving party favors to her own guests.
There are 3 bags of 12 party favors each. This gives us a total of 36 party favors.
There are 6 guests and so to evenly split the party favors, we must split 36 into 6 groups, giving us 6 party favors in each group.
COMPUTATION:
3 x 12 = 36
36 / 6 = 6

-2(x + 3) = -2(x + 1) - 4
Answer:
infinite solution
Step-by-step explanation:
-2 times x is -2x
-2 times 3 is -6
-2 times x is -2x
-2 times 1 is -2
the equation now looks like this:
-2x-6=-2x-2-4
Simplify
-2x-6=-2x-6
0=0
So this is an infinite solution

Please help me with this answer ASAP
Step-by-step explanation:
first let's bring the equation into "normal" form :
x - 2y = 2
-2y = 2 - x
2y = x - 2
y = x/2 - 1
so, the slope of this line is 1/2 (the factor of x - that is always the case in all lines).
a parallel line must have the same slope, of course.
so, its equation is
y = x/2 + b
now, b will be different to the -1 of the original equation, or the lines are identical.
it is the point of interception of the line through the y-axis (x = 0).
we get this by using the coordinates of the given point (4, -3).
so,
-3 = 4/2 + b = 2 + b
b = -5
therefore, the formula for the parallel line is
y = x/2 - 5

Given segment AX with point Q between A and X. AX = 25. AQ = 2y + 1. QX = 3y - 1.
We can set up an equation to solve for y using the fact that
y =
AQ =
QX =
Q
Answer:
y=5
AQ=11
QX=14
Q is not a midpoint
Step-by-step explanation:
A line segment can be divided into equal or unequal segments
The values of x, AQ and QX are 5, 11 and 14.
The given parameters are:
[tex]\mathbf{AX = 25}[/tex]
[tex]\mathbf{AQ = 2y + 1}[/tex]
[tex]\mathbf{QX = 3y - 1}[/tex]
[tex]\mathbf{AX = 25}[/tex] can be rewritten as:
[tex]\mathbf{AQ + QX =25}[/tex]
Substitute values for AQ and QX
[tex]\mathbf{2y + 1 + 3y - 1 =25}[/tex]
Execute like terms
[tex]\mathbf{5y =25}[/tex]
Divide both sides by 5
[tex]\mathbf{y =5}[/tex]
Substitute 5 for y in [tex]\mathbf{AQ = 2y + 1}[/tex] and [tex]\mathbf{QX = 3y - 1}[/tex]
[tex]\mathbf{AQ = 2 \times 5 + 1 = 11}[/tex]
[tex]\mathbf{QX = 3 \times 5 - 1 = 14}[/tex]
Hence, the values of x, AQ and QX are 5, 11 and 14.

Answer:
a is less than or equal to 7
Step-by-step explanation:
This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!

Answer:
Question 1 y=(1/4)x+8
Step-by-step explanation:
Use calculator
Answer:
1) y = 1/4x + 8
2) y = -x - 6
3) y = -2x - 1
4) y = -2/5x -3
5) y = 4x + 9
Step-by-step explanation:
1) y = 1/4x + c
6 = -2 + c
c = 8
y = 1/4x + 8
2) y = -x + c
-7 = -1 + c
c = -6
y = - x - 6
3) y = -2x+c
13 = 14 + c
c = -1
y = -2x - 1
4) 5y = -2x + 15
y = -2/5x + 3
Hence,
y = -2/5x + c
-10 = -2/5 + c
c = -3
Therefore,
y = -2/5x -3
5) Slope: (1-(-11))/(-2-(-5))
= (1+11)/(-2+5)
= 12/3
= 4
y = 4x +c
Substituting any one of the points:
1 = -8 + c
c = 9
y = 4x + 9

Ruby is saving up to buy a new jacket. She already has $25 and can save an additional $7 per week using money from her after school job. How much total money would Ruby have after 10 weeks of saving? Also, write an expression that represents the amount of money Ruby would have saved in ww weeks.
Total savings after 10 weeks:
Total savings after ww weeks:
From the question;
1) Ruby will save $95 after ten weeks
2) The equation for ww weeks is; S = $25 + ($7 x ww)
What is an equation?
Total savings after 10 weeks:
Ruby saves $7 per week from her after school job, and she already has $25, so her total savings after 10 weeks can be calculated as follows:
Total savings = Initial savings + (Weekly savings x Number of weeks)
Total savings = $25 + ($7 x 10)
Total savings = $25 + $70
Total savings = $95
So, Ruby would have a total of $95 after 10 weeks of saving.
Expression for the amount of money Ruby would have saved in ww weeks:
Let "S" represent the total savings after ww weeks.
Expression: S = $25 + ($7 x ww)

12 and (-12)
Step-by-step explanation:
Solve for x.
x^2= 144
square root both sides and get,
x= 12
and
x= (-12)
remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.
Answer:
x = 12
x = -12
Step-by-step explanation:
Step 1: Take the square root of both sides.
[tex]\sqrt{x^2} =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x = 12[/tex] or [tex]x = -12[/tex]Therefore, x = 12 and x = -12 are the answers.

Donna is collecting stamps. On the first day, she collects 5. On the second day, she collects 9. Each day, she collects 4 more stamps than the day before. How many total stamps will she have after 20 days?
Answer:
81 stamps
Step-by-step explanation:
Here we will use the AP formula
We know that
a_n = a + (n - 1)d
a = first term = 5
n = number of terms = 20
d = common difference = 9 - 5 = 4
On putting values
=> a_20 = 5 + (20 - 1)4
=> a_20 = 5 + (19)4
=> a_20 = 5 + 76
=> a_20 = 81
Therefore,
She will have 81 stamps after 20 days
[tex]\huge{\purple{\underline{\underline{\sf{\pink{ANSWER:-}}}}}}[/tex]
Here we have,
first term (a) = 5no. of terms (n) = 20 common difference (d) = 9 - 5 = 4[tex]\implies\tt{a_n = a + (n - 1) \times d} \\ \\ \implies\tt{a_20 = 5 + (20 - 1) \times 4} \\ \\ \implies\tt{a_20 = 5 + 19 \times 4} \\ \\ \implies\tt{a_20 = 5 + 76} \\ \\ \implies\tt{a_20 = 81}[/tex]
Hence, there will be 81 stamps after 20 days.Liam knows the key to making creamy risotto, a rice dish, is to add the liquid to the rice gradually. He adds 5 ladles of chicken broth to his rice before adding seasoning, and he continues to add 2 ladles of broth each minute afterwards.Write an equation that shows the relationship between the number of minutes since Liam added the seasoning, x, and the total number of ladles of broth he has added, y.
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5
Let x represent the number of minutes and y represent the total number of ladies.
Since he adds 2 ladles of broth each minute and he has 5 ladies initially, hence:
y = 2x + 5
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5
