Answer:
g = -18.3
Step-by-step explanation:
3g-10=-45
+10 (Cancel out the 10)
3g=-55
/3 (Divide by 3 to cancel out the 3)
g= -18.3
It’s 20 degrees because all triangles are all equal up to 180° and so if you add 135° to 25° you get 160° and so minus 160 from 180 and you’ll get 20°
Answer:
x = 2
y = -3
Step-by-step explanation:
Step 1: Write systems of equation
8x + 7y = -5
x = -3y - 7
Step 2: Solve for <em>y</em>
- Substitute 2nd equation into 1st: 8(-3y - 7) + 7y = -5
- Distribute 8: -24y - 56 + 7y = -5
- Combine like terms: -17y - 56 = -5
- Add 56 to both sides: -17y = 51
- Divide both sides by -17: y = -3
Step 3: Solve for <em>x</em>
- Substitute <em>y</em> to find <em>x</em>: x = -3(-3) - 7
- Multiply: x = 9 - 7
- Subtract: x = 2
Step 4: Check
<em>Plug in x, y into an original equation to verify it's a solution.</em>
2 = -3(-3) - 7
2 = 9 - 7
2 = 2
Answer:
<em>T tof = 2 ( v 0 sin θ 0 ) g . T tof = 2 ( v 0 sin θ 0 ) g . This is the time of flight for a projectile both launched and impacting on a flat horizontal surface.</em>
