Answer:
90 is the answer
Step-by-step explanation:
360° / 4= 90°
Answer:
x=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/10(x+34)=−2(4−x)
(1/10)(x)+(1/10)(34)=(−2)(4)+(−2)(−x)(Distribute)
1/10x+17/5=−8+2x
1/10x+17/5=2x−8
Subtract 2x from both sides.
1/10x+17/5−2x=2x−8−2x
−19/10x+17/5=−8
Subtract 17/5 from both sides.
−19/10x+17/5−17/5=−8−17/5
−1910x=−57/5
Multiply both sides by 10/(-19).
10/−19)*(−19/10x)=(10/−19)*(−57/5)
x=6
Lets solve the equation first:
<span> 0.5 – |x – 12| = –0.25
</span>= 1/2 - |x - 12| = -1/4
= 2 - 4<span>|x - 12| = -1
= 4|x - 12| = 3
= |x - 12| = 0.75
positive case, x >= 12
x - 12 = 0.75
x = 12.75
negative case, x < 12
x - 12 = -0.75
x = 11.25
So those are the two solutions.
These apply:
</span>1.) The equation will have no solutions.
2.) A good first step for solving the equation is to subtract 0.5 from both sides of the equation.
<span>3.) A good first step for solving the equation is to split it into a positive case and a negative case.
</span><span>5.) The negative case of this equation is x – 12 = –0.75.</span>
Answer: A trapezium.
Step-by-step explanation:
A car travels 440km in 15.4 hours -> In 1 hour, the car travel 1/(15.4) the distance.
So in an hour, the car travel : 440 x 1/(15.4) = 28.5714285714... (round to 29)
So, the average speed of the car is approximately 29 km/h
