You need to find a common denominator. The common denominator is 10. So 2/5*2=4/10
7/10-4/10=3/10
Trevor used 3/10 of a tank of gas.
Answer:
A
Step-by-step explanation:
put the 2 tires and times it by 2 to get the amount of four tires
If no base is mentioned, asssume base 10
remember

translates to

so
since no base mentioned, assume base 10

translates to

then
1000=2x
divide both sides by 2,
500=x
Y - 3x = -8
y = 3x - 8...slope here is 3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/3.
y = mx + b
slope(m) = -1/3
(3,2)...x = 3 and y = 2
now we sub and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur perpendicular equation is : y = -1/3x + 3
The sum of the measures of angles in all quadrangles is 360 °. Therefore:
