4(4) -4 = 16-4 = 12
She was wrong because she thought that x= 6
Factor is 2(13+3x)
Simplify is 26+6x
Speed is the rate of change of distance.
the speed of the truck for the 100 miles within 2 hours is
speed = 100 miles travelled / 2 hours taken
speed = 50 miles/hour
assuming that the driver drives at 50 miles/hr
the time taken to drive 50 miles is - 1 hour
therefore to drive 300 miles - it takes - 300 miles / 50 miles/hr
the time taken is - 6 hours
it takes 6 hours to drive for 300 miles
the scale factor or ratio of two similar figures, will be the same as the ratio of their perimeter, or even the ratio of two corresponding sides.
for example, we have say, an irregular octagon with a perimeter of say 13, and a similar octagon with a perimeter of 39, then
which is another way to say, the smaller is 1/3 of the larger one, or the larger one is 3 times as the smaller one.
Answer:
Step-by-step explanation:
Exterior angle is equal to the sum of opposite interior angles
3t - 37 + 2t - 14 = t + 46
Combine like terms
3t + 2t -37 -14 = t + 46
5t - 51 = t + 46
Subtract t form both sides
5t - 51 - t = 46
5t - t -51 = 46
4t - 51 = 46 {add 51 to both sides}
4t = 46 + 51
4t = 97
t = 97/4
t = 24.9°
