1 answer:
Lubov Fominskaja [6]3 years ago
7 0

Answer:

x=5

Step-by-step explanation:

(8x-8)3/2=64

(24x-8)/2=64 -You are distributing the three

12x-4=64 -You divide the whole thing by two

12x=60 -You subtract the four from both sides

x=5 - You divided the twelve from both sides

Hope this helps!

A city has a population of 250,000. The population is expected to decrease 1.5% annually for the next decade. Write a function t
notka56 [123]

Answer:

Population after t\ years=250000\times (0.985)^t

Step-by-step explanation:

If P is the initial amount, r is the annual rate of decrease then after t years the remaining amount(A) will be given by

A=P(1-\frac{r}{100})^t

Here P=250000, r=1.5\%\\\\A=250000(1-\frac{1.5}{100})^t\\\\A=250000(1-0.015)^t\\\\A=250000\times (0.985)^t

The employees of a hardware store ordered lunch from a local delicatessen. The lunch consisted of 4 turkey sandwiches and 7 orde
AleksandrR [38]

Answer:

Charges of Turkey is $6.25

Charges of French Fries is $1.90

Step-by-step explanation:

Given

Represent Turkeys with T and French Fries with F;

4T + 7F = 38.3

5T + 5F = 40.75

Required

Determine the values of T and F

5T + 5F = 40.75

Divide through by 5

T + F = 8.15

Make F the subject

F = 8.15 - T

Substitute 8.15 - T for F in the first equation

4T + 7F = 38.3

4T + 7(8.15 - T) = 38.30

4T + 57.05 - 7T = 38.30

Collect Like Terms

4T  - 7T = 38.30 - 57.05

-3T = -18.75

Solve for T

T = -18.75/-3

T = 6.25

Recall that:

F = 8.15 - T

F = 8.15 - 6.25

F = 1.90
