The length of pathway is 10 inches on map.

Step-by-step explanation:

Given,

Total distance = 350 miles

According to map,

1 inch = 35 miles

Let, x be the number of inches on map.

Therefore, using proportion;

Inch : mile :: inch : mile

$1:35::x:350\\$

Product of mean = Product of extreme

$35*x=350*1\\35x=350\\$

Dividing both sides by 35;

$\frac{35x}{35}=\frac{350}{35}\\x=10$

The length of pathway is 10 inches on map.

I HAVE TO TURN THIS IN IN 2 HOURS!!! PLEASE HELP!! I have the graph "y=(1/2)|x-3|-2" graphed but the question also wants the sol

leonid [27]

Answer:

1. Solutions for y=(1/2)|x-3|-2: x = -1 or x = 7

2. Solutions for 3|x+4|-5=-2: x= -5 or x =-3

3. Solutions for (2/3)|x+4|+3=2: No solution

Step-by-step explanation:

Solving for 1. You have to isolate the absolute value

y = (1/2)|x-3|-2

Let y = 0

0 = (1/2)|x-3|-2

Add 2 to both sides

2 = (1/2)|x-3|

Multiple by 2 to both sides

4 = |x-3|

When you have an absolute value, the, whatever the absolute value equals to can be either positive or negative. In this case -4 or +4. Solve for both:

-4 = x-3

x= -1

4 = x-3

x = 7

If you want me to explain 2, let me know.

There is no solution for 3. because you end up getting just a negative number and when you have absolute value, you can't have a negative.

The first discount on a camera was 18%. The second discount was 20%. After these two discounts the price was $328. What was the

Artyom0805 [142]

Answer:

$500

Step-by-step explanation:

We can find the original price of the camera through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities.

<u>Second Discount</u>

20% off means we paid 80%. We know we paid $328 of some price.

$\frac{80}{100} =\frac{328}{y}$
