Answer:
To solve an equation first you have to interpret the words / numbers. If it says 5 and a number is 7 then you have to write an equation, such as 5 + n = 7. When you solve it you have to subtract it from both sides.
5 + n = 7
-5. -5
n = 2
The price, P, of a sweater was discounted by 10% in
February. Because the sweater did not sell by the end of
the winter season, it was discounted by another 20% in
March. In terms of P, what was the price of the sweater
after the discount in March?
Answer:
In terms of P, the price of the sweater after the discount is 0.72P.
Step-by-step explanation:
Since the price P would represent 100% and the price was discounted by 10%, you can calculate 10% of 100% and subtract that amount, which would be:
100*10%=10
100-10=90%
This means that the price paid would be 90% of P. Then, the statement says that the price was discounted by another 20%. So, you have to calculate 20% of the price and subtract that amount from the price:
90*20%=18
90-18=72%
According to this, this means that in terms of P, the price of the sweater after the discount is 0.72P.

Five friends attend a matinee movie and spend $8 per ticket. They also purchase a small bag of popcorn each. The friends spend a total of $62.50. Let x be the price of a small bag of popcorn.
i dont know the answer can you help
Step-by-step explanation:
so each ticket is $8 so thats going to be 8x.There are 5 friends so you pay for 5 tickets they buy small bag of popcorn so let that have a variable of.p. then they spend a total of 62.50.
62.50=8(5)+p
62.50=40+p
-40. -40
22.50=p
so the 5 small bags of popcorn costs $22.50

Decide whether or not the relation is a function.
[(0,1), (-5,4), (0,2), (5,-4)]
Answer:
The relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Given the relation
{(0,1), (-5,4), (0,2), (5,-4)}
From the given relation is clear that the input value x = 0 is repeated twice.
In other words, the input value x = 0 is duplicated.
As we have already mentioned that we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, the relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.
UKMT Q8??? I have inserted the photo of the question
Answer: The distance is 15 units.
Step-by-step explanation:
Let's define the bottom left corner of the left rectangle as the point (0, 0).
we know that the rectangles are of 10 by 14, then the point O will be exactly on the middle of these two quantities (because the long side is on the horizontal axis, the point O could be written as):
O (7, 5)
Point M is on the top of the rectangle, then we know that the y component will be equal to 14.
And the x component is on the middle of the rectangle (this side is the one that measures 10 units)
the middle is 5.
And we also need to add the 14 units of the other rectangle that is lying down, then the x-component of this rectangle is 14+ 5 = 19
The point M is (19, 14)
We want to find the distance between the points (7, 5) and (19, 14)
We know that the distance between points (a, b) and (c, d) is:
Distance = √( (a - c)^2 + (b - d)^2)
In this case, the distance between points O and M will be:
distance = √( (7 - 19)^2 + (5 - 14)^2) = 15
Distance between points O and M is 15 units.

32 feet long and 6 yards wide what is the perimeter in feet
Answer:
100
Step-by-step explanation:
1 yard = 3 feet
6 yards = 18 feet
(18*2)+(32*2)
36+64
100
Answer: The perimeter is a 100 feet.
Step-by-step explanation:
If it is 32 feet long and 6 yards wide then I am thinking that the shape will be a rectangle.
To find the shape of a rectangle, you can use the formula, P = 2l+2w were P is the perimeter, l is the length, and w is the width.
But first since feet and yards are different measurements, and the question is asking for the perimeter in feet, then you will first have to convert 6 yards to feet.
6 yards = 18 feet
This means that the sides will be 32 feet long and 18 feet wide.
Now using the formula, input 32 for L and 18 for W and solve for P the perimeter.
P = 2(32) + 2(18)
P = 64+ 36
P = 100
Which value of x makes the equation 0.1x - 2.5 = 1.0 true
A 10

D 35
Answer:
D 35
Step-by-step explanation:
When figuring this out you can just plug in your answers if you want to take it the easier way by just putting in the 35 in places of x and multiplying 0.1 times 35 gets you 3.5 so 3.5 minus 2.5 is 1
