There are 4 fewer blue pens in a box than black pens. There are 15 black pens in each box.
How many blue pens are in 3 boxes?
Add 15 and 4. Then multiply the sum by 3.
Subtract 4 from 15. Then multiply the difference by 3.
Subtract 4 from 15. Then divide the difference by 3.
Answer:
the answer is: "Subtract 4 from 15. Then multiply the difference by 3."
Step-by-step explanation:
If there are 4 fewer blue pens in a box than black pens, and there are 15 black pens in each box, then that means there are 11 blue pens in each box.
So then, how many blue pens are in 3 boxes? There are 33 blue pens in 3 boxes, you can find this out by multiplying, 11 by 3.
the numerical answer is:
11 x 3 = 33
or, 3 x ( 15 - 4)

Ashley said 3/4 of her stuffed animals have buttons eyes. Pam said Ashley has 15 stuffed animals. is it possible that Pam is correct? Please explain.
Answer: No it is not possible
3/4 has a denominator of 4, which is not a factor of 15. This means that there is a contradiction somewhere. Note how (3/4)*15 = 11.25 is not a whole number. So if Ashley did have 15 stuffed animals, then 3/4 of that wouldn't be a whole number and it would contradict what Ashley is stating. The same can be said in reverse: if Ashley's statement is correct, then there's no way Pam is correct as well.

Ed is constructing the perpendicular bisector of a segment on his paper. He just finished
labeling the points of intersection of the two arcs that he drew. What is his next step?
Answer:
The next step is to draw a line connecting the two labelled points, that is from one side of the line to be bisected to the other
The line drawn in the above step, from the two labelled points is the perpendicular bisector of the segment
Step-by-step explanation:
To draw a perpendicular bisector of a segment, we have;
1. Ensure the compass is opened to more than half of the length of the segment to be bisected
2. Draw arcs of the same radius with center at the ends of the line to be bisected
3. Label the points where the arcs drawn from both ends cross each other on opposite sides of the line
4. Draw a line connecting the two labelled points, that is from one side of the line to be bisected to the other
5. The line so drawn from the two labelled points is the perpendicular bisector of the segment.

y = 4x - 3
y= 2x + 13
Answer:
x = 9, y = 29 or (8,29)
Step-by-step explanation:
Set the equations equal to each other because they both equal y:
4x - 3 = 2x + 13
Combine like terms:
2x = 16
Divide by 2:
x = 8
Plug 8 into the x for both equations and see if the y is the same:
y = 4(8) - 3 = 32 - 3 = 29
y = 2(8) + 13 = 16 + 13 = 29

Lewis was driving at 90 km per hour when he sneezed.
During the sneeze, his eyes were closed for half a second.
Work out how many metres he travelled in this time.
Answer:
12.5 m
Step-by-step explanation:
recall that 1 km = 1000 m
hence 90 km/h is equivalent to 90 km/h x 1000 m/km = 90,000 m/hr
also recall that 1 hour = 60 x 60 = 3600 s
hence 90,000 m/hr is equivalent to 90,000 m/hr x (1/3600) hr/s = 25 m/s.
given that is eyes were closed for 0.5 s.
in 0.5s, he travelled :
0.5s x 25 m/s = 12.5 m

He also has a piece of string that is 214214 ft long. Olivier needs to cut this string into 3 pieces that are all the same length to finish an art project. How long should each piece of string be?
Answer:
71.3 ft
Step-by-step explanation:
Oliver has a piece of string that is 214 ft long. He needs to cut this string into 3 pieces that are all the same length.
To find the length that each piece should be, we divide the length of the string by 3:
214 / 3 = 71.3 ft
Each piece should be 71.3 feet long.
Xavier, Thomas, and Mei had 650 marbles. Thomas had 3 times as many marbles as Mei. Mei had 50 fewer marbles than Xavier. How many marbles did Xavier and Mei have altogether? *
Answer: 230 Marbles
Step-by-step explanation:
Let Xavier marbles be x
Let Thomas marbles be y
Let Mei marbles be z
Xavier, Thomas, and Mei had 650 marbles.
x + y + z = 650
Thomas had 3 times as many marbles as Mei.
y = 3 × z
y = 3z
Mei had 50 fewer marbles than Xavier.
x = z - 50
We can plug all the equation gotten back into the first equation
x + y + z = 650
Since y = 3z and x = z - 50
x + y + z = 650
(z - 50) + 3z + z = 650
z - 50 + 3z + z = 650
5z - 50 = 650
5z = 650 + 50
5z = 700
z = 700/5
z = 140
Mei has 140 marbles
Since x = z - 50
x = 140 - 50
x = 90
Xavier has 90 marbles
y = 3z
y = 3 × 140
y = 420
Thomas has 420 marbles
Xavier and Mei marbles = 90 + 140
= 230 marbles
Prana has a savings account and a chequing
account with a total balance of $85.
His parents doubled the amount in each
account and the new total balance is $170.
How much money does Prana have in each
account?
Answer:
There is no unique solution to this problem and there are infinite number of possible solutions which can satisfy these equations.
Step-by-step explanation:
Let S represents Prana's savings account and C represents Prana's chequing account.
Prana has a savings account and a chequing account with a total balance of $85.
Mathematically,
S + C = 85 eq. 1
His parents doubled the amount in each account and the new total balance is $170.
Mathematically,
2(S + C) = 170
2S + 2C = 170 eq. 2
We have two equations and two unknowns.
S + C = 85
S = 85 - C
Substitute the above equation into eq. 2
2S + 2C = 170
2(85 - C) + 2C = 170
170 - 2C + 2C = 170
2C + 2C = 170 - 170
0 = 0
So what does it mean?
it means that there is no unique solution to this problem and there are infinite number of possible solutions which can satisfy these equations.
