X = 3y - 6
Vlad1618 [11]
X = 3y - 6....so sub 3y - 6 in for x in the other equation

2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y = 8 + 12
2y = 20
y = 20/2
y = 10

x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x = 24

solution is (24,10)

Explain what the inequality --4h &lt;-14 represents.<br> What value of h makes the equation true
KonstantinChe [14]

Answer:

-4h < - 14

We solve for h by applying the inverse operations;

The inverse operation of multiplication is division, so we divide by -4 on both sides;

/-4      /-4

h < 3.5, it could be <u>3.4, 3.3, 3.2 3.123, 2.4, 2.576</u>, there are tons of numbers below 3.5.

<u>So anything below 3.5 would best be suitable for the equation.</u>

Solve using elimination. <br> 10x + y = -19 <br> 10x + 3y = -17
RideAnS [48]

Subtract 10x

10x + y = -19

10x + 3y = -17

You would get:

-2y = -2

Two negatives make a positive number! Divide

y = 1

Plug in

10x + (1) = -19

10x = -20

Divide

x = -2

Your solutions are

x = -2

y = 1

tensa zangetsu [6.8K]

Answer:

The manual cost that will take to recreate by the firm is $ 90.51

Step-by-step explanation:

Given:

Number of words the manual contains= 16000

Number of words typed by a clerk in one hour and 20 minutes = 4160

To Find:

The total cost for recreating the manual = ?

Solution:

Step 1:  Finding the Number of hours is need to type 4160 words :

= 1\frac{20}{60} hours

\\\\=1\frac{1}{3} hours

\\\\=\frac{4}{3} hours

So it takes  \frac{4}{3} hours to type 4160 word

Step 2 :  Finding the Number of hours is needed to type 1 word  

= \frac{4160}{\frac{4}{3}}

=4160 \times \frac{3}{4}

= 3120 words per hour

Step 3 :  Finding the Number of hours is needed to type 16000 words

=\frac{\text{ total number of words}} {\text{ number of words written per hour}}

Substituting the values

= \frac{16000}{3120}

=  5.1282 hours

Step 4 :  Finding the cost for recreating the manual.

= number of hours  x cost per hour

=   5.1282 x $17.65

=  90.51
