Answer:
z = -4
Step-by-step explanation:
-5/2 = 3z/4 + 1/2
-10 = 3z + 2
-10 - 3z = 2
-3z = 12
12/-3 = -4
z = -4
Put in 1 for x and which problem gives you 7
the answer is y=7x
3/10 divided by 4/5
You can solve this problem by changing the second fraction and multiplying. 3/10 times 5/4 is 15/40 = 3/8
Answer:
×=1
Multiply both sides of the equation by 12, the least common multiple of 4,3.
3x+4(x−1)=3
Use the distributive property to multiply 4 by x−1.
3x+4x−4=3
Combine 3x and 4x to get 7x.
7x−4=3
Add 4 to both sides.
7x=3+4
Add 3 and 4 to get 7.
7x=7
Divide both sides by 7.
x=
7
7
Divide 7 by 7 to get 1.
x=1
Answer:
Step-by-step explanation:
Formula to be used,
A = 
Here, A = Final amount
P = Principal amount
r = rate of interest
n = Number of compounding (In a year)
t = Duration of investment (In years)
Question (5)
P = $4250
r = 0.015
n = 4
t = 3 years
A = 
A = 
A = $4445.24
Part (C)
1). P = $6000
r = 0.03
n = 2
t = 10 years
A = 
= 
= $8081.13
2). P = $9000
r = 0.05
n = 2
t = 8 years
A = 
= 
= $13360.55
