Write an inequality. One fourth of a number increased by 17 is at least 63

Luden [163]

Answer:

1/4x + 17 ≥ 63.

Step-by-step explanation:

'At least 63' is the same as ' greater than or equal to 63'.

So that would be 1/4x + 17 ≥ 63.

Can someone help me please.... with number 6,7,8,9

Alenkasestr [34]

Answer :

6. x=28

7.x =6

8. x =9

9. x =9

Step-by-step explanation:

$\frac{x + 2}{10} = 3$

$x + 2 = 3 \times 10 \\ x + 2 = 30 \\ x = 30 - 2 \\ x = 28$

(x+2)/10 = 3

Cross multiply

x+2 = 10 ×3

x+2 =30

Collect like terms and simplify

x =30-2

x = 28

$8x + 9 - 5x = 27 \\ 8x - 5x = 27 - 9 \\ 3x = 18$

$\frac{3x}{3} = \frac{18}{3} \\x = 6$

8x +9 -5x= 27

Collect like terms and simplify

8x-5x =27-9

3x =18

Divide both sides of the equation by 3

3x/3 = 18/3

x = 6

10x+8=8x+26

Collect like terms

10x-8x=26-8

2x = 18

Divide both sides of the equation by 2

2x/2 = 18/2

x = 9

2(x-5)+4x=x+35

Use 2 to open the bracket

2 × x =2x

2×(-5) =-10

2x-10+4x =x+35

Collect like terms and simplify

2x+4x-x = 35+10

5x = 45

Divide both sides of the equation by 5

5x/5 = 45/5

x =9

Anumeha is mowing lawns for a summer job. For every mowing job, she charges an initial fee of $ 10 $10dollar sign, 10 plus a con

slavikrds [6]

Answer:

F(t) = 10 + 5(t)

Step-by-step explanation:

The complete question is as follows;

Anumeha is mowing lawns for a summer job. for every mowing job, she charges an initial fee of \$10$10dollar sign, 10 plus a constant fee for each hour of work. her fee for a 555-hour job, for instance, is \$35$35dollar sign, 35. let f(t)f(t)f, left parenthesis, t, right parenthesis denote anumeha's fee for a single job fff (measured in dollars) as a function of the number of hours ttt it took her to complete it. write the function's formula.

Solution

We are interested in writing the function F(t) formula for the fee charged by Anumeha per job.

Now, the key to writing this function is knowing exactly the constant fee she charges on the job.

We were told that she got $35 for a 5 hour job.

Thus, the constant amount charged is as follows;

Since it’s $10 as initial fee and the constant fee is per hour;

35 = 10 + 5(x)

where x is the constant fee per hour

35 = 10 + 5x

5x = 35-10

5x = 25

x = 25/5

x = $5

This mess that she charges a constant fee of $5 per hour

So we can write the equation now.

F(t) = 10 + 5(t)

where t represents the number of hours she spent on the job
