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
Answer:
cos 2.78 = 1
Step-by-step explanation:
A = 9 because 11.2-2.2=9
B= 2.2 because 9+2.2=11.2
C=2.2 because 11.2-9=2.2
D=9.2 because 11.2-2=9
E=4.5 because 9.5-5=4.5
F= 5 because 9.5-4.5=5
G=4.5 because 9.5-5=4.5
H=5 because 9.5-4.5=5
I= x=11 because 99 divided by 9 = 11
J= x=9 because 99 divided by 11 = 9
K= 9 because 99 divided by 11 =9
L= 11 because 99 divided by 9=11
M=2 because 4 divided by 2 =2
N=4 because 2 times 2 =4
O=2 because 4 divided by 2 =2
P=2 because 4 divided by 2=2
hope this helps:)
B. -(-8 1/4) is the answer
Since it asks for the opposite of the opposite of it.
2 wks = 38 cm SO
1 wk= 19 cm
19 cm a week
19 x 3 = 57
1/2 wk = 8 cm
57 + 8 = 65 cm in 3 1/2 weeks
