Answer:
x= -1/3
y= -3 1/3
Step-by-step explanation:
Make both of them into y=Mx+b form
y=-x-3
y=(-x-7)/2
Substitute the x-3 in the first equation for the y in the second one.
x-3=(-x-7)/2
2x-6=-x-7
3x=-1
x=-1/3
Now that we have x, we can solve for y.
y=-x-3
y=-1/3-3
y=-3 1/3
Answer:
The best estimate for the number of hours the family drove is 28.8 Hours.
Step-by-step explanation:
The distance Jarrod's family drove is 1778 miles and their average speed was 61.7 miles/hour, and we need the best estimate for the number of hours the family drove. For this we use the distance formula

and use solve for t:

Thus the best estimate for the hours driven is 28.8 hours.
<em>It is only an estimate because the speed given is the average speed.</em>

Step-by-step explanation:
The weight of 9 bags is 5.4 blocks
<em><u>Solution:</u></em>
Given that,
5 bags weigh the same as 3 blocks
We have to find how many blocks will 9 bags weigh
Let "x" be the weight of 9 bags
Then,
5 bags weigh the same as 3 blocks
9 bags weight the same as "x" blocks
From proportion we can say,
5 : 3 : : 9 : x
Therefore,

Thus the weight of 9 bags is 5.4 blocks
