John bought a shirt on sale for 25% off the original price and another 25 % off the discounted price. If the final price was $16, what was the price before the first discount?
Answer: original price = p
price after first 24% discount = .75p
he second 25% discount reduces the already reduced price to .75*.75p = .5625p
So, if .5625p = 16,
p = 16/.5625 = $28.44
check:
25% off $28.44 = $21.33
25% off $21.33 = $16.00

: -- ) PLEASE HELP me out with this one
Answer:
A
Step-by-step explanation:
To answer this, we need to see what happens to the curves on the given interval
For f(x), we have that there is a decrease as we are moving from a higher positive value of y to a lower positive value of y over the specified interval
For g(x), we can see that we are moving from a lower positive y value to a higher positive y value
What this mean is that the first option is correct
Solve: (8-u)-(5u+1) with steps
Answer:
-6u + 7
Step-by-Step Explanation:
Rearrange Terms:
(8 - u) - 1(5u + 1)
(-u + 8) - 1(5u + 1)
Distribute:
(-u + 8) - 1(5u + 1)
(-u + 8) - 5u - 1
Eliminate Redundant Parentheses:
(-u + 8) - 5u - 1
-u + 8 - 5u - 1
Subtract the Numbers:
-u + 8 - 5u - 1
-u + 7 - 5u
Combine Like Terms
-u + 7 - 5u
-6u + 7
Solution:
-6u + 7

use the trigonometry mnemonic (new monic) to help remember how sin cos and tan fit on the triangle
since you know the angle and you want to know the side opposite of that angle... and you know the side adjacent ( next to) the angle... use Tan
use the mnemonic to help
Tan(Ф)= Opp/ Adj ( we know two of these things and we want the 3rd :P )
Adj * Tan(25) = Opp
250 * Tan(25) = Opp
116.5769.... = Opp

Which equation represents a functional relationship?..
Y=6
X=6
Plz justify your answer~
Answer:
defines y as a function of x, because for every x value there is no more than a y value. (In fact for every x there is exactly one y value). We can forgive a function if some values of x do not have a y, but if there is more than one y for even one value of x, then the relation is not a function.
x=y2+6 does not define y as a function of x, because some value(s) of x have more than one y.
In general,
x=y2-6--->x+6=y2
So, all the values of x larger than -6 would have two y values.
For example, x=10 would be paired with y=4 and y=-4.
A function cannot assign more than one y to any x value.

.15m - .13m = 69.96 - 55.96
Answer:
m=7
Step-by-step explanation:
15m−13m=69.96−55.96
Step 1: Simplify both sides of the equation.
15m−13m=69.96−55.96
15m+−13m=69.96+−55.96
(15m+−13m)=(69.96+−55.96)(Combine Like Terms)
2m=14
2m=14
Step 2: Divide both sides by 2.

Step-by-step explanation:
Blanca jogged 8 days last month she jogged 1.25 miles on each day and burned 140 calories per mile while jogging how many calories did Blanca burn by jogging last month
Answer:
140p calories
Step-by-step explanation:
Bianca is said to have jogged km 8 days, while also completing 1.25 miles every day. First, we calculate the total number of miles Bianca jogged in total, and that is
8 * 1.25 = 10 miles
Therefore, Bianca jogged a total of 10 miles the previous month.
Again, it is said that Bianca burned 140 calories per each mile she jogged and were asked to find the total calories that was burnt.
If Bianca burns 140 calories per mile, then she must have burnt 140 * 10 calories in 10 miles.
Therefore, we conclude that Bianca burnt 1400 calories.
13. If l is parallel to m, find the values of x and y.
Answer: 14. x = 16; y = 23
15. x = 9; y = 13
Step-by-step explanation:
14. (4x + 4) = (7x - 44) (alternate exterior angles are congruent)
4x + 4 = 7x - 44
Collect like terms
4x - 7x = -4 - 44
-3x = -48
Divide both sides by -3
x = -48/-3
x = 16
39° + (8y - 43)° = 180° (consecutive exterior angles are supplementary)
39 + 8y - 43 = 180
Add like terms
-4 + 8y = 180
Add 4 to both sides
8y = 180 + 4
8y = 184
Divide both sides by 8
y = 184/8
y = 23
15. (15x - 26)° = (12x + 1)° (alternate exterior angles are congruent)
15x - 26 = 12x + 1
Collect like terms
15x - 12x = 26 + 1
3x = 27
Divide both sides by 3
x = 27/3
x = 9
28° + (12x + 1)° + (4y - 9)° = 180° (sum of interior angles of ∆)
Plug in the value of x
28 + 12(9) + 1 + 4y - 9 = 180
28 + 108 + 1 + 4y - 9 = 180
Add like terms
128 + 4y = 180
Subtract 128 from each side of the equation
4y = 180 - 128
4y = 52
Divide both sides by 4
y = 52/4
y = 13

Solve the system of equation by elimination.
27= -3y + x
2 y=10 - 4x
Answer:
x=6 y=-7
Step-by-step explanation:
rearrange the equation
3y=x-27 eq 1
2y=-4x+10 eq 2
Multiply eq 1 by 2, and eq 2 by 3
6y=2x-54
6y=-12x+30 subtract the two eq's
0=14x-84
84=14x
x=84÷14
x=6
solving for y sub. x either eq 1 or 2
3y=x-27
3y=6-27
3y=-21
y=-21÷3
y=-7
