6900 + 8100 = 15000
15000 divided by 2 = 7500
So your answer is 7500
Answer:
<h2><u><em>
13°</em></u></h2>
Step-by-step explanation:
AFR = VFN (opposite angle rule)
7x + 33 = 9x + 7
33 - 7 = 9x - 7x
26 = 2x
x = 26 : 2
x = 13°
-----------------
check
7 * 13 + 33 = 9 * 13 + 7 (remember PEMDAS)
91 + 33 = 117 + 7
124 = 124
the answer is good
Answer:15 miles
Step-by-step explanation: well he biked for all of the 15 miles!?
-2x+6y=6
-7x+8y=-5
2(7x+8y=-5)
-7(-2x+6y=6)
Distribute
14x+16y=-10
14x-42y=-42
eliminate
-26y=-32
divide
y=1.2
-2x+6(1.2)=6
-2x+7.4=6
subtract 7.4 on both sides
-2x=-1.4
divide
x=0.7
I believe this is right
Weight is measured by the force of gravity, which changes throughout different planets, moons, etc.
Mass is the measure of the amount of mass in an object, in which it never changes, no matter where you are. So if the astronaut's mass on earth was 80 kg, his mass on the moon would still be 80 kg
