Solve y=3x-7 and 4x+3y=18 by substitution

sveta [45]

Answer:

x = 3 and y = 2

Step-by-step explanation:

y = 3x - 7

substituting for y in 4x + 3y = 18, we will have

4x + 3(3x -7) = 18

4x + 9x - 21 = 18

13x = 18 + 21

13x = 39

x = 3

Substituting for x in y = 3x -7, we have

y = 3(3) - 7

y = 9 - 7

y = 2

lana [24]

Ft (full time)= $2,400/ monthpt (part time)= $200/ week15% taken from taxes------------------------- 1 year= 12 months; 1 month= 4 weeks (12*2,400) + (4*12*200)= $38,400 you made in a year I set up the problem this way because you want to know how much you made that whole year, so if there are 12 months in a year, and you get paid $2,400 a month, then from your full time job you ear (12*2,400). From your PT job you make $200 a week, there are 4 weeks in a month and 12 months in a year, so to calculate what you earned from your PT job, you do: 4*12*200 15% of what you made is deducted from taxes:0.15(38,400)= $5,760 After taxes, you made:$38,400-$5760= $32,640

Nidhi is thinking of a number n, and she wants her sister to guess the number. Her first clue is that eight less than three time

Dmitriy789 [7]

Answer:

The range of numbers that Nidhi might be thinking of is between 3 and 9.

Step-by-step explanation:

We are given that Nidhi is thinking of a number n, and she wants her sister to guess the number.

Her first clue is that eight less than three times her number is between one and nineteen.

Let the number Nidhi is thinking be 'n'.

So, eight less than three times her number means that;

$(3\times \text{n}) - 8 = 3\text{n}-8$

Now, according to the question; the above equation is between one and nineteen, so;

$1< 3\text{n}-8 < 19$

Adding 8 to the whole expression;

$1+8< 3\text{n}-8 +8< 19+8$

$9< 3\text{n}< 27$

Dividing the whole expression by 3;

$\frac{9}{3} < \frac{3\text{n}}{3} < \frac{27}{3}$

$3< \text{n}< 9$

Hence, the range of numbers that Nidhi might be thinking of is between 3 and 9.
