Answer:
315 m/s = 1134 km/h
Step-by-step explanation:
Multiply the speed value by 3.6
315 x 3.6 = 1134
Answer:
Part A, one solution
Part B, x=3
Step-by-step explanation:
divide both sides of the equation by 7 (5x-13=2)
move the constant to the right hand side and change its sign (5x=2+13)
add numbers (5x=15)
divide both sides of the equation by 5 (x=3)
hope this helps, have a good day
Answer:
there is one solution in my opinion
Step-by-step explanation:
Let's call the missing angles Q, R, and S. We know that Q = 2R and S = R - 8 and we also know that Q + R + S = 180. So that really just means that 180 = 4R - 8 Add 8 on both sides of the equal sign
188 = 4R So we divide on both sides of the equal sign by 4
47 = R And that means that Q = 2 * 47 So Q = 94 and S = 47 - 8 So S = 39
39 + 94 + 47 = 180
The missing angles are 39 degrees 94 degrees and 47 degrees.
Answer:
(-5,29)
(2,1)
(4,-7)
Step-by-step explanation:
y = -4x + 9
When x is -5;
y = -4(-5) + 9 = 29
When x is 2;
y = -4(2) + 9 = 1
When x is 4;
y = -4(4) + 9 = -7
