PLEASE HELP Solve |4x - 7| = 13.
Answers
so 4x-7=13
add 7 to both sides
4x=20
divide both sides by 4
x=5
this is one solution
4x-7=-13
add 7 to both sides
4x=-6
divide both sides by 4
x=-1.5
x=5 or -1.5

He marked down DVD players by 36%, and he marked down stereo tuners by 22%. If DVD players cost $41.60 after the markdown and stereo tuners cost $69.42 after the markdown, which item’s price was reduced by more, and by how many dollars more was it reduced? Round all dollar values to the nearest cent.

Answer:
Option A. 191cm²
The area of the circle is 191 cm²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 7.8cm
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (7.8cm)²
a = 3.14 * 60.84cm²
a = 191.03 cm²
The area of the circle is 191.03 cm²

Answer:
x = -2/3
y = 10/9
Step-by-step explanation:
3y - 4x = 6
x=3y-4
Substitute the second equation into the first for x
3y - 4( 3y-4) =6
3y - 12y +16 = 6
Combine like terms
-9y +16 = 6
Subtract 16 from each side
-9y +16-16 = 6-16
-9y = -10
Divide by -9
-9y/-9 = -10/-9
y = 10/9
x = 3y -4
x =3(10/9) -4
=10/3 - 12/3
=-2/3

Answer:
37 and -18
Step-by-step explanation:
Let one number be x and other y
1 x + 1 y = 19 .............1
1 x -1 y = 55 .............2
Eliminate y
multiply (1)by 1
Multiply (2) by 1
1 x 1 y = 19
1 x + -1 y = 55
Add the two equations
2 x = 74
/ 2
x = 37
plug value of x in (1)
1 x + 1 y = 19
37 + 1 y = 19
1 y = 19 -37
1 y = -18
y = -18
37 and -18
Final answer:
The two numbers, which sum to 19 and have a difference of 55, are 37 and -18.
Explanation:
The sum and difference of two numbers can provide the solution to the problem. In this case, the sum of the two numbers is 19 and the difference is 55. To solve this, we start by setting up two equations based on the problem: x + y = 19 and x - y = 55.
Then we solve these equations simultaneously. We can add the two equations together to eliminate 'y'. This gives us 2x = 74, or x = 37. Substituting x = 37 into the first equation, we get 37 + y = 19, which gives y = -18.
So, the two numbers are 37 and -18.
