Answer:
20 laps
Step-by-step explanation:
2 times = +1 dollars for Paula, +0.50 dollars for Jacki
Try multiplying it the least amount of times to Paula can have more and so 20 times and Paula will have 20 dollar sand Jacki will have 19.75, therefore she needs to do 20 laps.

Write the equation of the line in point-slope form.
Answer:
y-1= -3/4(x-1)
Step-by-step explanation:
find the slope then put it in the format: y2-y1=m(x2-x1)
y-1= -3/4(x-1)
Answer:
y = -3/4x + 7/4
Step-by-step explanation:
So we have 2 points:
(-3, 4) & (1, 1)
The formula for point-slope is:
y - y1 = m (x - x1)
First, we need to find the slope between the points
The formula for this is
(y2 - y1) /(x2 - x1)
1 - 4 / 1 - (-3) ->
-3 / 4
Our slope is -3/4 (m)
y = -3/4 (x + 3) + 4
I've done this using a simplified formula for point slope which is
y = m(x - x1) + y1
we can simplify this equation more
y = -3/4x + 7/4
is our final equation.
Simplify the following to standard form
1.(9x+7y+8z)+(2x+ -4y+7z)
2. (5x +10y+ -8z) - (2x+ -2y + -3z)
Answer:
1, 11x + 3y + 15z
2, 3x + 12y + -5z
Step-by-step explanation:
all you need to do is combined the like terms and make sure the signs (positive and negative signs) are right
A student has a savings account with $475 in it. She deposits $125 of her paycheck into the account every week. Her goal is to save $7,000 for college.
a.How much will be in the account after 3 weeks?
b.How long will it take before she has $1,350?
c.Write an equation that represents the relationship between the dollar amount in her account and the number of weeks since she started depositing $125 each week.
d.Graph your equation using graphing technology. Mark the points on the graph that represent the amount after 3 weeks, and also the week she has $1,350. Write down the coordinates.
e. How long will it take her to reach her goal?
9514 1404 393
Answer:
a. $850
b. 7 weeks
c. f(x) = 125x +475
d. see attached (3, 850), (7, 1350)
e. 53 weeks
Step-by-step explanation:
a.After 3 weeks, $125×3 = $375 will have been added to the $475 already in the account. The balance will be ...
$375 +475 = $850
__
b.The student will have to add $1350 -475 = $875 to her account to reach $1350. At a rate of $125 per week, that will take ...
$875/($125/week) = 7 weeks
__
c.The initial value is $475, and the rate of change is $125 per week, so the equation can be written ...
f(x) = 475 +125x . . . . . . . balance after x weeks
__
d.See the attached graph with the required points marked. (3, 850), (7, 1350)
__
e.It will take more than 53 weeks for the student to reach her goal. (After 52 weeks, the account will have $6975, so will be $25 short of the goal.)

is 18/3 an irrational number
Answer:
Yes it is irrational
Step-by-step explanation:
Hope this helps
The number 18/3 is 6 which is not an irrational number.
What is an irrational number?An irrational number, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.
here, we have,
18/3
= 6
So, its not an irrational number.

−4−6
Step-by-step explanation:
I NEED HELP PLEASE!!!!!!
Answer:
Step-by-step explanation:
Two angles are alternate and has same measurement because line l and line m are parallel so to find x:
4x - 50 = 2x + 30
4x - 2x = 30 + 50 add/subtract like terms
2x = 80 divide both sides by 2
x = 40

The airline tickets to Jamaica that you want to buy just went on sale. They were originally $1100 and the sale price is $600. What percentage is the original price marked down?
Step-by-step explanation:
100% = $1100
1% = 100%/100 = 1100/100 = 11
how many % are $600 ?
that is how often does 1% fit into $600 ?
600 / 11 = 54.545454... %
rounded that means 55%.
so, the making down percentage is then the difference
100% - 55% = 45%

Omar can jog 3 2/5 miles in 2/3 of an hour. Find his average speed in miles per hour.
Answer:
9.6miles per hour
Step-by-step explanation:
2/3＝40min
32/5 /40＝0.16
0.16miles per min
0.16*60＝9.6
Step-by-step explanation:
he jogs 3 2/5 miles in 2/3 of an hour.
3 2/5 miles are 17/5 miles.
now, to get mph as speed unit, we need to bring the 2/3 hour to 1 hour.
we need to multiply 2/3 by a factor to get 1
2/3 × x = 1
2x = 3
x = 3/2
since we have to multiply the denominator of the ratio by 3/2, we also need to multiply the numerator by the same value to keep the overall value of the ratio/fraction the same.
17/5 / 2/3 × 3/2 / 3/2 = (17/5 × 3/2) / (2/3 × 3/2) =
= ((17×3)/(5×2)) / ((2×3)/(3×2)) =
= (51/10) / 1 = 51/10 = 5.1 mph
so, his jogging speed is 5.1 mph.
