Andrew and Thomas collected a total of 190 bugs for a science project. Andrew collected 10 more
bugs than Thomas. Which number sentence shows
the number of bugs that Andrew collected, b?

The largest numbers of described species in the U.S. fall into four insect Orders

Step-by-step explanation: its right

b + b - 10 = 190

⇒ 2b - 10 = 190

Step-by-step explanation:

Let b = number of bugs Andrew collected

⇒ b - 10 = number of bugs Thomas collected

Given total number of bugs = 190

b + b - 10 = 190

To solve:

    b + b - 10 = 190

⇒ 2b - 10 = 190

⇒ 2b = 200

⇒ b = 100

Therefore, Andrew colleted 100 bugs and Thomas collected 90 bugs.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
