Answer:
Distance travelled by Monarch butterfly = 2000 miles
Distance travelled by desert locust = 2800
Distance travelled by pink-spotted hawk moth= 7800 miles
Step-by-step explanation:
Let the distance travelled by Monarch butterfly be "X" miles
Distance travelled by desert locust is equal to X + 800 miles
Distance travelled by pink-spotted hawk moth is equal to 4X -200 miles
The total distance travelled by the three is equal to 12600 miles

Distance travelled by Monarch butterfly = 2000 miles
Distance travelled by desert locust = 2000 + 800 = 2800
Distance travelled by pink-spotted hawk moth = 4 * 2000 -200 = 7800 miles
A word problem is used to solve problems in mathematics without the explicit use of equations initially.
<h3>What is a Word Problem?</h3>
This refers to the use of words to generate an equation that can be solved by mathematical means.
Hence, we can see that because the question is incomplete, we can infer that there is a relationship that exists between Dr. White, Dr. Black, Dr. Brown, and a woman that does not have brown hair, and equality would be used to solve it.

#SPJ1
<span>8(x-3.7)
To find this, you must first use the distributive property.
8 • x = 8x
8 • -3.7 = -29.6
</span>8(x-3.7) = 8x - 29.6
Since there is no way to completely solve this since it's only an expression and not an equation, this is in simplest form.
