6+9x=456
Subtract 6 from both sides
6-6+9x = 456-6
9x = 450
Divide each side by 9
X = 50
Plug it in 6+9(50) = 456
6+450 = 456
Answer:
Step-by-step explanation:
<1=180°-74° so <1=126°
<2=180°-90° so <2=90°
<3=180°-116° so <3=64°
<4=180°-65° so <4=115°
by using 
° =(3)180°/5 -<1 -<2 -<3 -<4 =<5
you find out the last.
Answer:a
Step-by-step explanation:
Answer = 36.0 mph
As per the question,
Actual speed of the car = 40 mph.
Speedometer has a percent error of 10%.
The error can be negative as well as positive.
If the error is negative, it means speedometer is showing less speed than actual speed= - 10%
10 % of 40 = 4
speed shown by speedometer = 40 - (10% of 40) = 36 mph
If the error is positive, it means speedometer is showing more speed than actual speed = +10%
speed shown by speedometer = 40 + ( 10% of 40) = 44 mph
as per the given options, correct option is 36.0 mph
