Recall your d = rt, distance = rate * time
let's say we have two cars, A and B, B has a speed rate of "r", so A is the faster one and has a speed rate of " r + 10 "
they both are 300 miles apart after 3hrs, after 3hrs, car has been running for 3hrs, and car B has also been running for 3hrs, so their time is the same
we know their distances added up, is 300miles, so if car B covered say, "d" distance on those 3hrs, car A covered the slack, " 300 - d "

solve for "r"
Answer:
you could multiply 15 times 5 or you could add 15 five times
Step-by-step explanation:
There is a baseball game. It is 2$ for every person, which is x, that wants to watch the game. After the game, you pay the umpires a total of 125$. After the end of the day you have made 400 dollars. How many people came to the game. So find x.
Answer:x = 7
x = 2
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is +14
Step-1 : Multiply the coefficient of the first term by the constant 1 • 14 = 14
Step-2 : Find two factors of 14 whose sum equals the coefficient of the middle term, which is -9 .
-14 + -1 = -15
-7 + -2 = -9 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and -2
x2 - 7x - 2x - 14
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-7)
Add up the last 2 terms, pulling out common factors :
2 • (x-7)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-7)
Which is the desired factorization
Answer:
seed Mix A is more expensive than Seed Mix B.
Step-by-step explanation:
The graph of Mix A is above the graph of Mix B.
Looking at the labels of the graphs, we see that the x-axis represents the number of bags bought and the y-axis represents the cost.
For every point along the x-axis, Mix A's cost is above Mix B's cost. This means that Mix A is more expensive.Step-by-step explanation:
