Answer:

The distance is 750 miles.

Step-by-step explanation:

In order to find this, we create a proportion. On the left would be the scale factor. On the right would be the Idaho to Arizona distance.

1in / 300 mi = 2.5in / x mi

Now we can cross multiply to find the distance.

300 * 2.5 = 1 * x

750 mi = x

elixir [45]
A + R + J = 1925
A = 1/2R
J = 2R

1/2R + R + 2R = 1925
7/2R = 1925
R = 550

J = 2(550)
J = 1100

nikdorinn [45]

Answer:

Answer: 3

Step-by-step explanation:

Use BODMAS

<u>Step 1: Open bracket (1 2/5 +3.5÷1 1/4 )</u>

<em>Convert mixed fractions into improper fractions</em>

7/5 + 3.5 ÷ 5/4

<em>Divide 3.5 by 5/4</em>

7/5 + 2.8 = 4.2

<u>Step 2: Carry out all divisions</u>

<em>Convert mixed fraction into improper fractions</em>

4.2 ÷2 2/5 +3.4÷2 1 /8 −0.35

4.2 ÷ 12/5 + 3.4 ÷ 17/8 - 0.35

1.75 + 1.6 - 0.35

<u>Step 3: Solve</u>

1.75 + 1.6 - 0.35

3.35 - 0.35

Answer = 3
