Brad bought a total of 9 CD's and tapes. The CD's cost $7 each and the tapes cost $6 each. He paid a total of $58. How many of each did he buy?
I ONLY NEED THE EQUATION...I can get the numbers of cans and peas I just need the equations to find the numbers
This is Algebra....please help me!!
Answer:
Step-by-step explanation:
Let the number of CD's = c
Let the number of tapes = t
Total number of CD's and tapes = 9
c + t = 9 --------------- (i)
Cost of 'c' CD's = 7*c = 7c
Cost of 't' tapes = 6*t = 6t
Total cost = $ 68
7c + 6t = 58 -----------------(ii)
Multiply the first equation by (-6) and then add the equations.
(i)* (-6) -6c - 6t = - 54
(ii) 7c + 6t = 58 {Now add. here t will be cancelled}
c = 4
Number of CD's = 4
Plugin c = 4 in equation (i)
4 + t = 9
t = 9 - 4
t = 5
Number of tapes = 5

Answer:
A = 6
B = 10
Step-by-step explanation:
[] Let's look at the system again:
[tex]\left \{ {{Ax+By=38} \atop {2Ax-By=16}} \right.[/tex]
[] They give us a set of x and y values, (3, 2) so we can plug them into the system.
[tex]\left \{ {{A(3)+B(2)=38} \atop {2A(3)-B(2)=16}} \right.[/tex]
[] Now, we can solve this with a graphing calculator. Let A be x and B be y for the sake of graphing.
A = x
B = y
[tex]\left \{ {{x(3)+y(2)=38} \atop {2x(3)-y(2)=16}} \right.[/tex]
-> See attached
[] We can see the lines intersect at (6, 10) so the answer is A = 6 and B = 10.

A = 6 - 35 B = 3x + 53
Solve for x then find the measure of A.
Answer:
A = 73°
Step-by-step explanation:
A + B = 180 because of alternating interior angles
Substitute each angle
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
Substitute A
A = 6x - 35
A = 108 - 35
A = 73
Hope this helps
Have a great day!

1) A car moves with a speed of 40 km/h for 15 mins and then with a speed of 60 km/h for next 15 mins . The total distance covered by the car is : _________
(a) 100km. (b) 25km
(c) 15km. (d) 10km
• Don't spam
• Need Genuine Answer with Explanation .
Answer:
25 km
Explanation:
Distance = speed * time
We have change time which are given in minutes to hour. As the speed is mentioned in kilometre per hour.
For part A:
[tex]\rightarrow Distance = speed * time[/tex]
[tex]\hookrightarrow Distance = 40 * \frac{15}{60}[/tex]
[tex]\hookrightarrow Distance = 10[/tex] km
For part B:
[tex]\rightarrow Distance = speed * time[/tex]
[tex]\hookrightarrow Distance =60 * \frac{15}{60}[/tex]
[tex]\hookrightarrow Distance = 15[/tex] km
Total distance covered:
part A + part B
10 km + 15 km
25 km
25 km
Solution :-Speed of the car in first 15 mins ,
The car is moving in the speed of 40 km/h for 15 mins.
Distance covered = speed × Time taken Distance covered = 240 × 15/60 = 10 kmSpeed of car in next 15 mins ,
again ,
distance covered = 60 × 15/60 = 15kmnow , total distance covered = ( 10 + 15 ) km = 25 km

Step-by-step explanation:
Ten years ago the father was six times as old as his daughter. After ten years, he will be twice as old as his father . Determine their present age ..
Let
10years ago
Daughter's age=xFather's age=6x10years after
Daughter's age=x+20Father's age=6x+20ATQ
[tex]\\ \tt\hookrightarrow 6x+20=2(x+20)[/tex]
[tex]\\ \tt\hookrightarrow 6x+20=2x+40[/tex]
[tex]\\ \tt\hookrightarrow 4x=20[/tex]
[tex]\\ \tt\hookrightarrow x=5[/tex]
Father's present age=6x+10=6(5)+10=30+10=40yrsDaughter's present age=x+10=5+10=15yrs▪︎If ten years ago , the age of daughter was x years , then , ten years ago the age of her father was 6x years ▪︎
Present age of father = ( 6x + 10 ) years Present age of the daughter = ( x + 10 ) yearsTen years after ,
Father's age = ( 6x + 10 + 10 ) years => ( 6x + 20 ) years Daughter's age = ( x + 10 + 10 ) years => ( x + 20 ) yearsAccording to the question,
▪︎6x + 20 = 2 ( x + 20 )
6x + 20 =! 2x + 40 6x - 2x = 40 - 40 4x = 20 x = 5Therefore , Present age of the Father = 6x + 10 = 6 × 5 + 10 = 40 years and present age of the daughter,
x + 10 = 5 + 10 = 15 yearshence , the age of his daughter is 15 years
