Terry is purchasing a bike that is on sale for 40% off the original price. After a coupon is applied that reduces the sale price by 20%, Terry's final cost for the bike is $168. What was the original price of the bike Terry is purchasing?
Answer:
$420
Step-by-step explanation:
(100 - 40)x = 60x
60x - 20 = 40x
0.4x = $168
x = $168/0.4 = $420
3x + 7 = y-5
trying to find y
Answer: Simplifying
3x + 7 = y + -5
Reorder the terms:
7 + 3x = y + -5
Reorder the terms:
7 + 3x = -5 + y
Solving
7 + 3x = -5 + y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 3x = -5 + -7 + y
Combine like terms: 7 + -7 = 0
0 + 3x = -5 + -7 + y
3x = -5 + -7 + y
Combine like terms: -5 + -7 = -12
3x = -12 + y
Divide each side by '3'.
x = -4 + 0.3333333333y
Simplifying
x = -4 + 0.3333333333y

What is an equivalent expression for 4(2m + n)
Answer:
8m+4n
Step-by-step explanation:
4(2m+n)
you have to distribute 4 to 2m and n
so your answer will be
8m+4n
Hope this helped :))
Answer:
8m + 4n
Step-by-step explanation:
To find the answer, you should distribute the 4 on the outside of the parentheses to each of the terms inside the parentheses, which would get: 4(2m) + 4n.
Simplify 4(2m) by multiplying, which gets 8m.
The equation is then 8m + 4n, which cannot be added together because the variables are different.

What is the volume of the triangular prism
Hight 10in
Base 14 in
Length 6
Answer:
[tex]V=336\ in^3[/tex]
Step-by-step explanation:
Triangular Prism
Given a triangular prism of base area A and height H, its volume is obtained with the formula:
V = AH
The area of the base is calculated as follows:
[tex]A = \frac{WL}{2}[/tex]
Where W is the width and L is the length. Both dimensions must be perpendicular.
The triangle of the base has a hypotenuse equal to 10 in and the width is 6 in, the length is calculated by:
[tex]L=\sqrt{10^2-6^2}[/tex]
[tex]L=\sqrt{100-36}=\sqrt{64}[/tex]
L = 8 in
The area is:
[tex]A = \frac{6*8}{2}[/tex]
[tex]A = 24\ in^2[/tex]
Finally, the volume is:
[tex]V = 24\ in^2*14\ in[/tex]
[tex]\boxed{V=336\ in^3}[/tex]
What is the volume of this container

Step-by-step explanation:
width of the cupboard = 1m
1m to cm
1 × 100= 100cm
100cm + 84cm = 184cm
1m = 100cm
184/100 = 1.84m

Your friends shuffle the cards and then deal them. Select probability of getting a red card. Select probability of getting a spade card.
Answer:
1/2 ; 1/4
Step-by-step explanation:
Number of cards in a deck = 52
Number of red cards = 26
Number of spades = 13
Probability of event A :
P(A) = required outcome / Total possible outcomes
P( red card) = number of red cards / total cards in deck
P(red card) = 26 / 52 = 1/2
P(spade) = number of spades / total cards in deck
P(red card) = 13 / 52 = 1 / 4

A school chorus has 90 sixth-grade students and 75 seventh-grade students. The music director wants to make groups of performers, with the same combination of sixth- and seventh-grade students in each group. She wants to form as many groups as possible.
Answer:
The music director could make 15 groups of performers with 6 6th grade students and 5 7th grade students in each group.
Step-by-step explanation:
Since in the question it is mentioned that
There is 90 6th grade students and 75 7th grade students
Now factor could be done in the following ways
90 = 2 × 45 = 2 × 3 × 15 = 2 × 3 × 3 × 5
75 = 3 × 25 = 3 × 5 × 5
Now the GCF of 90 and 75 is
= 3 × 5
= 15
So,
90 = 15 × 6
75 = 15 × 5
Hence, The music director could make 15 groups of performers with 6 6th grade students and 5 7th grade students in each group.

Answer:
b=3, y=6
Step-by-step explanation:
Label the 2 equations:
2b +6y= 42 -----(1)
2b +4y= 30 -----(2)
(1) -(2):
(2b +6y) -(2b +4y)= 42 -30
2b +6y -2b -4y= 12
2y= 12
y= 12 ÷2 (÷2 on both sides)
y= 6
Susbt. y=6 into (2):
2b +4(6)= 30
2b +24=30
2b= 30 -24 (-24 on both sides)
2b= 6
b= 6 ÷2
b= 3
Answer:
y = 6, b = 3
Step-by-step explanation:
Since both equations have 2b in them, subtracting them gets you a quick result because the 2b-2b cancels out!
2b + 6y = 42
2b + 4y = 30
------------------ -
2y = 12
y = 6
Then 2b = 42 - 36 = 6, so b = 6/2 = 3
I thought of a number, subtracted it from 6 1/4 , multiplied the difference by 1 2/3 and then by 2 4/5 . The result was the same as the result of division of 146 by 5 3/14 . What was my number?
Answer:
The number was 1/4
Step-by-step explanation:
Let the
number be x
from the question, we have
6 1/4 - x
multiplied difference;
(6 1/4 - x) 1 2/3
The
next multiplication will give;
1 2/3 * 2 4/5
= 5/3 * 14/5 = 14/3
So we have;
(6 1/4 - x) 14/3
Result is same as:
146 divided by 5 3/14
= 146 * 14/73 = 28
Thus;
(61/4 - x) * 14/3 = 28
(25/4 - x) * 1/3 = 28/14
(25/4 - x) * 1/3 = 2
(25-4x)/4 = 6
25-4x = 6(4)
25-4x = 24
25-24 = 4x
4x = 1
x = 1/4

What is 1 + 3 (x - 5)
Answer:
1 + 3 (x - 5) = 3x - 14
Step-by-step explanation:
Given:
1 + 3 (x - 5)
Open parenthesis
= 1 + {(3 * x) - (3 * 5)}
= 1 + (3x - 15)
= 1 + 3x - 15
= 3x - 14
1 + 3 (x - 5) = 3x - 14

How do you simplify square roots.
Answer:
Simplifying a square root just means factoring out any perfect squares from the radicand, moving them to the left of the radical symbol, and leaving the other factor inside the radical symbol. If the number is a perfect square, then the radical sign will disappear once you write down its root.

FIND THE VALUEOF THE VARIBLE AND FILL THE BLANK.
6) 23F-17=29
7) 2(3G+4)=56
8) H+9=0
9) 3(K-8)=96
10) 5M-5=0
Answer:
f = 2
g = 8
h = -9
k = 40
m = 1
Step-by-step explanation:
Equation 1:
23f - 17 = 29
Add 17 to both sides. This undoes the -17.
23f = 29 + 17
Add 17 to 29 to get 46.
23f = 46
Divide both sides by 23. This undoes the multiplication by 23.
f = 46/23
Divide 46 by 23 to get 2.
f = 2
Equation 2:
2(3g + 4) = 56
Divide both sides by 2. This undoes the multiplication by 2.
3g + 4 = 56/2
Divide 56 by 2 to get 28.
3g + 4 = 28
Subtract 4 from both sides. This undoes the +4.
3g = 28 - 4
Subtract 4 from 28 to get 24.
3g = 24
Divide both sides by 3. This undoes the multiplication by 3.
g = 24/3
Divide 24 by 3 to get 8.
g = 8
Equation 3:
h + 9 = 0
Subtract 9 from both sides. This undoes the +9.
h = 0 - 9
Any number subtracted from 0 gives its negation.
h = -9
Equation 4
3(k - 8) = 96
Divide both sides by 3. This undoes the multiplication by 3.
k - 8 = 96/3
Divide 96 by 3 to get 32.
k - 8 = 32
Add 8 to both sides. This undoes the -8.
k = 32 + 8
Add 8 to 32 to get 40.
k = 40
Equation 5:
5m - 5 = 0
Add 5 to both sides. This undoes the -5
5m = 0 + 5
Anything plus 0 gives itself.
5m = 5
Divide both sides by 5. This undoes the multiplication by 5
m = 5/5
Anything divided by itself gives you 1.
m = 1
