Answer:

a and f

Step-by-step explanation:

a. x + 3 = 5x - 4

x - 5x = -4 - 3

-4x = -7

x = -7/-4

x = 7/4

b. x - 3 = 5x + 4

x - 5x = 4 - 3

-4x = 1

x = -1/4

c. 2x + 8 = 5x - 3

2x - 5x = -3 - 8

-3x = -11

x = -11/-3

x = 11/3

d. 10x + 6 = 2x - 8

10x - 2x = -8 - 6

8x = -14

x = -14/8

e. 10x - 8 = 2x + 6

10x - 2x = 6 + 8

8x = 14

x = 14/8

f. 0.3 + x/10 = 1/2x - 0.4

3/10 + x/10 = 1/2x - 4/10

x/10 - 1/2x = -3/10 - 4/10

x/10 - 5/10x = -7/10

-4x/10 = -7/10

-4x = -7

x = -7/-4

x = 7/4

Answer:

5P3*6C4=60*15=900

Step-by-step explanation:

5P3 refers to the permutations of 5 items taken 3 at a time. To evaluate this, we use factorials as follows;

5P3=\frac{5!}{(5-3)!}

The factorial of an integer n is evaluated as;

n!=n*(n-1)*(n-2)*(n-3).......3*2*1

Using this concept, the above expression can now be simplified as follows;

5P3=\frac{5!}{2!}=\frac{5*4*3*2!}{2!}=5*4*3=60

Therefore, the permutations of 5 items taken 3 at a time is 60.

The next expression, 6C4 refers to the combinations of 6 items taken 4 at a time. The simplification utilizes similar concepts of permutations since we shall be involving factorials;

6C4=\frac{6!}{4!(6-4)!}=\frac{6!}{4!*2!}=\frac{6*5*4!}{4!*2*1}=\frac{6*5}{2*1}=15

Therefore, the combinations of 6 items taken 4 at a time is 15.

The final step is to evaluate the product;

5P3*6C4=60*15=900

The student council had six fund raisers during the school year. They raised $212, $205, $206, $190, $188, and $195. Using the c
Rus_ich [418]

Answer:

$1200

Step-by-step explanation:

The clustering method for estimation is a method used for estimating the sums and products of numbers. This method is used when the numbers that are to be multiplied or added are near in value to a single number.

Given the money raised by six fund raisers:

$212, $205, $206, $190, $188, and $195

The numbers are to be added to find the total money raised. i.e.:

$212 + $205 + $206 + $190 + $188 + $195

But all the numbers are close to $200. Hence:

Using clustering method = $200 + $200 + $200 + $200 + $200 + $200 = 6 * $200 = $1200

Sever21 [200]

Answer:

$900

Step-by-step explanation:

Use the formula for simple interest:  i = p r t, where i is the interest earned, p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.

Here, i = $27 = p(0.015)(2), or

               $27 = 0.03p

Dividing both sides by 0.03, we get:

p = $27 / 0.03 = $900

The principal, in this situation, was $900.
