Answer:
Step-by-step explanation:
Let x = the number of all the species of birds sighted in the park
“300 species of birds that migrate. This accounts for 2/7 of all the species of birds sighted in the park”
the above sentence means “(2/7)x = 300”
now we can solve it :
(2/7)x = 300
⇔ 2x = 7×300
⇔ 2x = 2100
⇔ x = 2100/2
⇔ x = 1050
Answer:
Step-by-step explanation:
Let x be the number
- Write it out: -26x - 22 = x - 90
- Combine like terms: -27x + 68 = 0
- Subtract 68 from each side, so it now looks like this: -27x = -68
- Divide each side by -27 to cancel out the -27 next to x. It should now look like this:
