The product of a number x minus 5 and three less than twice x

Answers

Answer:

(x-5)(2x-3)

Step-by-step explanation:

key words:

product = multiplication

minus - subraction

x-5

and = first phrase times next phrase

less than = a number minus the number before the 'less than'

twice = 2 times a number

if we put it together we get x-5 times 2x-3. we put parenthesis because we dont want to multiply only 5 and 2x so our answer is (x-5)(2x-3).

Suzy's Sculpting gym charges a $10 application fee and $12 per month for membership. Tami's Toning does not charge an application fee, but charges $14 per month for membership. After how many months will the total cost of membership be the same for both gyms?

Answers

Answer:

Total cost of membership will be the same for both gyms after 5 months.

Step-by-step explanation:

Given: Suzy's Sculpting gym charges a $10 application fee and $12 per month for membership.

Tami's Toning does not charge an application fee, but charges $14 per month for membership.

To find: After how many months will the total cost of membership be the same for both gyms

Solution:

Let [tex]t[/tex] denotes number of months after which total cost of membership will be the same for both gyms

For Suzy's Sculpting gym,

Total charges [tex]= 10+12t[/tex]

For Tami's Toning,

Total charges [tex]=14t[/tex]

Now solve [tex]10+12t=14t[/tex]

[tex]10+12t=14t\\10=14t-12t\\10=2t\\t=\frac{10}{2}\\ t=5[/tex]

So, total cost of membership will be the same for both gyms after 5 months.

Answers

Answer:

c = 13

Step-by-step explanation:

In a rectangle the diagonals bisect each other, thus

FG = FI , substitute values

7c - 67 = c + 11 ( subtract c from both sides )

6c - 67 = 11 ( add 67 to both sides )

6c = 78 ( divide both sides by 6 )

c = 13

Answer:

c = 13

Step-by-step explanation:

We know FG and FI are equal to each other because F is the cross section of a rectangle.

FG = 7c - 67

FI = c + 11

FG = FI

7c - 67 = c + 11 Add 67 to each side so it will cancel on the left

7c = c + 11 + 67

7c = c + 78 Subtract c from each side so it cancels on the right

7c - c = 78

6c = 78 Divide each side by 6

6c/6 = 78/6

c = 78/6

c = 13

Rachel is saving money to buy an outfit for a party she has already saved $17 she is earning $5 each month for being a mother's helper to the family next door how many weeks until she has in 39 points $50 to buy the outfit from the store consider she is only paid for working a full week not a 1/2 week.

Answers

Answer:

18 weeks

Step-by-step explanation:

Let the number of months she worked since she is paid monthly be represented by x

The Equation to solve this question is given as:

$17 + 5 × x = $39.50

17 + 5x = 39.50

5x = 39.50 - 17

5x = 22.50

x = 22.50/5

x = 4.5 months

We are asked to calculate how many weeks.

Hence we convert the number of months to weeks

1 month = 4 weeks

4.5 months = x

4.5 × 4 = 18 weeks

Therefore, she works for 18 weeks

Answer: I got 5.0 weeks. and i got it right. it says she got paid for a FULL week, not half a week. if she got paid half it would be 4.5, but in this problem it’s focused on whole so it’s 5.0 weeks. hope this helped!

Bode Chambers is a flight attendant with an annual gross pay
of $54,400. He is single and is paid on a monthly basis. How
much is withheld monthly for state taxes?

Answers

Answer:

$750.00

Step-by-step explanation:

$54,400 ÷ 12 = $4366.66

the first $1000, is taxed at 1.5%

1000 × .15 = $150.00

that leaves Bode with $3366.66 of taxable income.

the first $2000.00 is taxed at 3%.

2000 × .3 = $600.00

leaving $1366.00 of non-taxable income. since it's below a second $2000, Bode's state has squeezed out as much as legally allowed from his paycheck.

$150.00 + $600.00 = $750.00

Bode should move to a less greedy state.
