Answer:
21°
Step-by-step explanation:
set it up
7x-1+3x-9=180
combine like terms
10x-10=180
take the ten to the other side
10x=190
divide both sides by 10
x=19
plug x in
3(10)-9
30-9
21
(Incase you need it the other angle is 159°)
Answer:
The depth now is 47 feet below the surface of the lake
Step-by-step explanation:
Step 1: Determine initial depth
Initial depth=surface level-depth below surface
where;
Surface level=0, since its the point of reference
depth below surface=96 feet
replacing;
Initial depth=(0-96)=-96 feet
Step 2: Final depth
Final depth=Initial depth+distance covered
where;
Initial depth=-96 feet
distance covered=+49 feet since the scuba driver moves towards the surface
replacing;
distance covered=-96+49=-47 feet
The depth now is 47 feet below the surface of the lake
I just answered this.... :]
x - 0.05x = 57,
0.95x = 57,
57/0.95 = original price
Original price = $60
Answer:
Well it would be 100 days
Step-by-step explanation:
Because they had pizza every ten days and if you add 5 days a week that's 50 days they sell pizza. If your talking corn they sell it every 4 days times 5 days a week that's 20 days of corn. Then you do 50 x 20 and then you get 100 days of pizza and corn, so it would be 100 days before they sell pizza and corn together again!
