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
The answer should be D if not then B
Total Profit = P(a,b) = ($0.40a) + ($0.40b), where a = # of apples sold and b = # of bananas sold.
Discriminant = sq root of b^2 - 4*a*c =
sq root of 36 - 4*1*13 =
sq root 36 -52 =
sq root 36 -52 =
sq root -16
There are no real solutions for this equation. Both roots are complex numbers.
Answer:
A= 0.5 x (a+b) x h
124 = 0.5 x (12+19) x h
124 = 15.5 x h
÷15.5
h = 8cm
0.5x(12+19) x 8 does gives 124
Thus, height is 8cm.
Hope this helps!
