Answer:
3) 4x=15
6)b=$2.5
1) n= -12
Step-by-step explanation:
3. Given the equation ,
#Expand by removing the brackets:
#We then group the like terms to solve for x:
2+4x=17
4x=15
Hence, the equations equivalent is 4x=15
6. Let b be the cost of each bag of snack.
-Given that there are 4 friends who spent a total of $34 and each ticket costed $6.
-We equate the costs to the total to solve for b:
Hence, the cost of each bag of snack is $2.5
1) Given the equation
#First. we multiply each term by 3 to remove the fraction:
#We then group like terms together to solve for n:
#Divide all terms by -2 to get the value of n:
Hence n= -12
I think d....im not sure if its right tho :) sorry
Answer:
Y-3=-6(x-7)
Step-by-step explanation:
Y-y1=M(x-x1)
Y-3=-6(x-7)
Y-3=6x-42
Add 3 to both sides
Y=6x-39
Welp, I gave you slope intercept form and point slope form.
Answer:
Approximately .
Step-by-step explanation:
Convert the angle of this sector to radians:
.
The formula relates the arc length of a sector of angle (in radians) to the radius of this sector.
In this question, it is given that the arc length of this sector is . It was found that radians. Rearrange the equation to find the radius of this sector:
.
The perimeter of this sector would be:
.
Answer:
Step-by-step explanation:
Start by calculating the effective rate of interest:
.09/52= .0017307
(we divide by 52 because there are 52 weeks in a year)
Then just use the annuity formula
