A. We must consider that Marisa is walking a straight trail
so that the time required to cover a distance is persistent or constant.
B. The slope of the line is: y = m x + b
Where in this problem, y is the distance, m is the slope or
the time it takes for each block, x is the time, and b would be the y intercept
or the initial location of Marisa.
C. The slope m can be calculated using the formula:
m = (y2 – y1) / (x2 – x1)
m = (8 – 12) / (6 – 0)
m = -0.67
The negative sign is the space between Marisa and Sanjay’s
home is declining by time. It further means that there is a cut in 0.67 blocks
per minute.
D. y = - 0.67 x + b
The starting point of Marisa is at 12 blocks away from
Sanjay’s home, therefore let b be 12.
Finding for time when distance is y = 0:
0 = -0.67 x + 12
x = 17.9 minutes
Therefore it takes approximately 17.9 minutes to go to Sanjay’s
home.
Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
The number of seahorses is 4 times the number of sea urchins.There are 16 seahorses write and solve and equation to find how many sea urchins are there.
Let
x ----> the number of seahorses
y ----> the number of sea urchins
we know that
The number of seahorses is 4 times the number of sea urchins
so
-----> equation A
There are 16 seahorses
so
----> equation B
Solve the system by substitution
substitute equation B in equation A
solve for y
divide by 4 both sides
5/100 = 0.056 sales tax
$12+$26+$125 = $163 total purchases without tax
163*0.056 = 9.128 tax based on how much she bought
$163 + 9.128 = $172.128 total amount she paid.
Hope this helps!
Answer:
His total budget is $5000
Step-by-step explanation:
800/x=16/100
16x=80000
