Answer:

x > 7

Step-by-step explanation:

0.8 - 3.2x < -2 - 2.8x

Add 2.8x to both sides.

0.8 - 0.4x < -2

Subtract 0.8 from both sides.

-0.4x < -2.8

Divide both sides by -0.4. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality symbol changes direction.

x > 7

Answer:

Graph the points, (2,18) (7, 24) and (16, 0)

Step-by-step explanation:

Going to the store takes 2 minutes for 18 blocks, which is the first point

He stays at the store for 2 minutes then takes 3 minutes to get to the bank which is 6 blocks away, add the time together and blocks, and you get the second point

He stopped at the bank for 3 minutes and the drove back home. It takes him 6 minutes to get back home, (24/6), add all the minutes together and you get 16.

(This is assuming the graph is y for blocks and x for minutes)

What is the LCD of 1/6 and 5/12 and 11/18

Oksi-84 [34.3K]

Finding the Lowest Common Denominator of: $\frac{1}{6} ; \frac{5}{12} ; \frac{11}{18} 
$

Here's to find out how it was our LCD: $\frac{1}{6} = \frac{6}{36}$
$\frac{5}{12} = \frac{15}{36}$
$\frac{11}{16} = \frac{22}{36}$
To find the fraction on the right side we had to multiply (and somewhat divide to get the answer)

So, therefore the Lowest Common Denominator of this question would most likely be: $36$

Good Luck!

Ok this is the last one . lol

Molodets [167]

Answer:

Step-by-step explanation:

Because these two angles are supplementary, their angle measures must add up to 180 degrees. Therefore:

3x+2+2x+23=180

5x+25=180

5x=155

x=31

Hope this helps!

If the cost of producing a product that sells for $50 is 120,000 plus $20.00 per piece, then how many products must be sold to b

Vadim26 [7]

Let
x--------->number of products
y1--------> the cost of producing a product
y2------> the cost of sell a product

we know that
y1=120,000+20x-------> equation 1
y2=50x------> equation 2

equate equation 1 and equation 2
120,000+20x=50x
50x-20x=120,000
30x=120,000
x=4000

the answer is
4000 pieces
