what is the LCM of 80 and 60
Answer:
240
Step-by-step explanation:
Answer:
240
Step-by-step explanation:
What I do is I first multiply the two numbers...
(60 * 80 = 240)
From there I try and find if there is any number lower than the product of these two numbers... if there isn't... then the product is the LCM
Since the only factor between 80 and 240 is 160... that is the only other possible answer... since 160 is not a multiple of 60... the answer can only be 240.
I hope this helps and wasn't too confusing:)
Martin traveled at an average rate of 40 miles per hour for the first half of his trip. For the second half of his trip, he traveled at a rate of 60 miles per hour. How far did he travel in the 4-hour trip?
Answer:
Total distance traveled = 200 miles
Step-by-step explanation:
Total time taken for the trip = 4 hours
∴ The trip can be divided into two halves of 2 hours each.
1st half:
speed = 40 miles per hour
distance = speed × time
when time = 2 hours
distance = 40 × 2 = 80 miles
2nd half:
distance = speed × time
speed = 60 miles per hour
time = 2 hours
∴ distance = 60 × 2 = 120 miles
Combined distance traveled = 80 + 120 = 200 miles

The school band is selling candy to raise $1,800.00 to pay for their trip to a band festival. The band earns $1.50 from every box of candy sold. Kayla solved the inequality 150 x greater-than-or-equal-to 1,800 to find the number of boxes the band must sell to meet their goal. She graphed her solution on a number line and interpreted the solution to mean the band will meet their goal if they sell fewer than 12 boxes.

A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
a pound. How many pounds of wooden blocks and plastic bricks should be used to make a
10-pound mixture that would sell for $80?
9514 1404 393
Answer:
6 # plastic bricks4 # wooden blocksStep-by-step explanation:
Let p represent the number of pounds of plastic bricks in the mix. Then the number of pounds of wooden blocks is (10-p), and the total cost is ...
10p +5(10-p) = 80
5p = 30 . . . . . . . . . subtract 50
p = 6 . . . . divide by 5; there are 6 pounds of plastic bricks in the mix
4 pounds of wooden blocks and 6 pounds of plastic bricks should be used to make a 10-lb mix worth $80.
If x=3 then y=21. What is the value of x when y=105
Answer:

Your family buys tickets for the Ranger game. Each ticket costs $16. You also have to pay for parking. After buying 4 tickets, your total bill is $96.50.
a) How much did you pay for parking?
b) Write an equation that gives your total bill (in dollars) as a function of the number of tickets you buy. Be sure to define your variables!
c) How many tickets could you buy with $250 if you also have to pay for parking?
Part (a)
Answer: $32.50
--------------------
Work Shown:
Each ticket costs $16. If you buy four of them, then you paid 4*16 = 64 dollars.
The total bill was $96.50
This leaves 96.50-64 = 32.50 for parking.
======================================================
Part (b)
Answer: y = 16x+32.50
--------------------
Work Shown:
x = number of tickets
y = total bill (in dollars)
1 ticket costs 16 dollars
x tickets cost 16x dollars since we multiply both values by x
Add on the cost of parking to get a total bill of y = 16x+32.50
======================================================
Part (c)
Answer: at most 13 tickets
In other words, 13 is the max you can get.
--------------------
Work Shown:
Plug y = 250 into the equation found back in part (b). Solve for x
We'll follow PEMDAS in reverse to isolate x
y = 16x+32.50
250 = 16x+32.50
16x+32.50 = 250
16x = 250-32.50
16x = 217.5
x = 217.5/16
x = 13.59375
Since we can't buy a fraction of a ticket, we must round down to the nearest whole number. We cannot round to x = 14 despite the value 13.59375 being closer to 14 as it is to 13.
x = 13 is the answer we're after.
If we plug in x = 13, we get
y = 16x+32.50 = 16*13+32.50 = 240.5
while x = 14 leads to
y = 16x+32.50 = 16*14+32.50 = 256.5
The first result of $240.50 is under $250 while the second result $256.50 is over $250. So that's why x = 13 is the largest number of tickets we can buy.
a) The parking fee is $32.50.
b) The equation is T(N) = 16N + Parking fee
c) Approximately 13 or 14 tickets.
We have,
a)
Total bill - Cost of tickets = Parking fee
$96.50 - ($16 * 4) = Parking fee
$96.50 - $64 = Parking fee
Parking fee = $32.50
b)
Total bill = T
Number of tickets = N
The equation that gives your total bill (in dollars) as a function of the number of tickets you buy is:
T(N) = 16N + Parking fee
c)
T(N) = 16N + Parking fee
Substituting the given values:
$250 = 16N + Parking fee
$250 = 16N + $32.50
$250 - $32.50 = 16N
$217.5/16 = N
N ≈ $13.6
Thus,
a) $32.50
b) T(N) = 16N + Parking fee
c) Approximately 13 or 14 tickets.

Linear parent function f(x)=x is graphed on the grid. Which graph best represents
h(x) = -f(x) + 3
Answer:
See graph image
Step-by-step explanation:
If f(x)=x, and we substitute f(x) into h(x), we get h(x)=-(x)+3. The graph of -x+3 is shown in the image attached.
The graph which best represents the function; h(x) = -f(x) + 3 is the graph of h(x) = -x + 3 as in the attached image.
The function, f(x) is given as; f(x) = x.
However, the required graph is the graph of;
h(x) = -f(x) + 3
where, f(x) = x.Therefore,
h(x) = -x + 3Therefore, the graph of h(x) has intercept, h(x) = 3 and slope, m = -1 as in the attached image.

how do u solve (2d-5)/2 = (5d+2)/9
Answer:
D= 49/8
Step-by-step explanation:
Cross-multiply.
(2d-5)/2 = (5d+2)/9
(2d−5)*(9)=(5d+2)*(2)
18d−45=10d+4
Subtract 10d from both sides.
18d−45−10d=10d+4−10d
8d−45=4
Add 45 to both sides.
8d−45+45=4+45
8d=49
Divide both sides by 8.
d= 49/8
So the answer is 49/8

Find the 15th term in the following arithmetic sequence
1, 6, 11, 16, ...
Answer:
Step-by-step explanation:
21,26
26 is the answer
Answer:
15th term is 71
Step-by-step explanation:
Explicit Rule for arithmetic sequence is: Tn = a + (n - 1)*(d), where a is the first term and d is the common difference
The first term is 1, hence a = 1
The common difference is 5 (6 - 1 = 5, 11 - 6 = 5...), hence d = 5
Tn = 1 + (n - 1)*(5)
We are trying to find the 15th number.
T₁₅ = 1 + (15 - 1)*(5)
= 1 + (14)*(5)
= 1 + 70
