But if the asker puts out a reward of more points, if you have the best answer, you get the points they awarded.
Questions with higher point rewards tend to get answered faster. Hope this helps!
Answer:
1) 3 2) y=73x
Step-by-step explanation:
For number 1):
(y2-y1)/(x2-x1)= (-4-[-1])/(-2-[-1])= (-3)/(-1) = 3
For number 2):
Speed=miles/hour= miles per hour
Speed= 146 miles/2 hours= 73 miles per hour
<span>37.5 inches
If the model is an accurate scale model, then the ratio of a dimension in the model to the dimension in real life will remain a constant. So we have
6/75 = 3/X
where
6 = length of model
75 = length of actual car
3 = width of model
X = width of actual car
Solving for x, gives
6/75 = 3/X
6 = 225/X
6X = 225
X = 37.5
So the actual car width is 37.5 inches.</span>
X^2+7-4 that’s the answer don’t simplify it
The answer is 12/30.
We have 12 red marbles and 30 marbles in total, so the probability is red marbles/total marbles=probability of getting a red marble!
