distance= rate ÷ time
time= rate ÷ distance
time= 200 km/hr ÷ 1400 km
time= 1/7 hr or 0.1428... hr
Answer:
x = 65 , y = 64
Step-by-step explanation:
y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is
y - 16 + 2y + 4 = 180
3y - 12 = 180 ( add 12 to both sides )
3y = 192 ( divide both sides by 3 )
y = 64
then
2y + 4 = 2(64) + 4 = 128 + 4 = 132
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2y + 4 is an exterior angle of the triangle , then
x + 67 = 132 ( subtract 67 from both sides )
x = 65
Answer:
3/5=x
Step-by-step explanation:
3÷x=5
multiply both sides by x
x(3÷x)=(5)x
cancel out x on the left side of the equation
3=5x
divide both sides by 5
3/5=(5x)/5
cancel out 5 on the right side
3/5=x
