A student buys
6
music albums and
4
video games. The cost of
1
video game is
$
16
more than the cost of
1
music album.
If the student spends exactly
$
164
, what is the cost of each music album?
Answer: 10$
Step-by-step explanation:
164 - 4x16 = 100
6 + 4 = 10
100 : 10 = 10
Simplify each expression by combining like terms -14w+10w-11+2w

Three vertices of parallelogram WZXY are W(-5, 2), X(2, 4) and Z(-7, -3). Find the coordinated of the vertex, Y.
Answer:
[tex]Y = (4,9)[/tex]
Step-by-step explanation:
Given
[tex]W(x_1,y_1) = (-5, 2)[/tex]
[tex]Z(x_4,y_4) = (-7, -3)[/tex]
[tex]X(x_2,y_2) = (2, 4)[/tex]
Required
Find Y
To do this, we make use of the mid-point formula
i.e.
[tex]M = \frac{1}{2}(x_n+x_m,y_n+y_m})[/tex]
WX and ZY are the diagonals of the parallelogram.
The mid-point of WX is:
[tex]M = \frac{1}{2}(-5+2,2+4)[/tex]
[tex]M = \frac{1}{2}(-3,6)[/tex]
The mid-point of ZY is:
[tex]M = \frac{1}{2}(-7+x,-3+y)[/tex]
Equate both values of M
[tex]\frac{1}{2}(-3,6) = \frac{1}{2}(-7+x,-3+y)[/tex]
Multiply both sides by 2
[tex](-3,6) = (-7+x,-3+y)[/tex]
By comparison:
[tex]-7 + x = -3[/tex]
[tex]-3 + y = 6[/tex]
[tex]-7 + x = -3[/tex]
[tex]x = 7 -3[/tex]
[tex]x = 4[/tex]
[tex]-3 + y = 6[/tex]
[tex]y = 6 +3[/tex]
[tex]y = 9[/tex]
Hence:
[tex]Y = (4,9)[/tex]
A single bacterium lands in your mouth and starts growing by a factor of 4 every hour. After how many hours will the number of bacteria exceed 1,000?
Answer:
After 5 hours, the number of bacteria will be 1024
Step-by-step explanation:
1 times 4 = 4
4 times 4 = 16
16 times 4 = 64
64 times 4 = 256
256 times 4 = 1024
It will take around 5 hours to exceed 1000

A banana costs three times as much as an apple. The total cost of 1 banana and 1
apple is $1.60. If a represents the cost of 1 apple, which equation could you use to
find a?
Answer:
banana cost 1.20 and the apple cost 0.4
Step-by-step explanation:
1.60 divided by 4 = 0.4 and the cost of apples
1.60 - 0.4 = 1.2 and the cost of bananas
since the banana cost three times you divide by two and subtract that number from the total cost to get three times the amount of the apples price. hope this helped sorry for my spelling

Step-by-step explanation:
To find surface area, we must calculate each of the rectangular prism's faces and add them.
1 × 5 = 5
1 × 5 = 5
3 × 5 = 15
3 × 5 = 15
1 × 3 = 3
1 × 3 = 3
5 + 5 + 15 + 15 +3 + 3 = 46
a. 46 m²
What is 11/2 subtracted by 11/3
Answer:
11/6
Step-by-step explanation:
Answer:
1 5/6
First make it a mixed number. 11/2=5 1/2. 11/3=3 2/3. Next, you find the common denominator. 2 and 3 are both multiples of 6. You multiply 11x3=33, 2x3=6, 11x2=22 3x2= 6. Your new numbers are 5 3/6 and 3 4/6. Now you subtract. 5-3=2, but you have to regroup, so you end up with 1. 9/6-4/6=5/6. 1+5/6=1 5/6
