100 PTS!!!! The perimeter of a rectangle is 4(4x - 5) inches. the length of the sides of the rectangle are 2 x + 3 inches and 3x + 2 inches. WRITE AND SOLVE an EQUATION to find the length of each side of the rectangle. ( you have to show all work for branliest!!!!! :D)
Answer:
2 sides are [tex]\frac{33}{13}[/tex] or 2.5
2 sides are [tex]\frac{47}{13}[/tex] or 3.6
Step-by-step explanation:
There must be 2 2x+3s and 2 3x+2s
The perimeter is the sum of the sides (it has 4 sides)
2(2x+3) + 2(3x+2) = 4(4x-5)
distributive property
2*2x + 2*3
4x+6
other one
2*3x + 2*2
6x+4
perimeter
4*4x + 4*-5
16x-20
together...
(4x+6) + (6x+4) = 16x-20
add like terms
10x+10 = 16x-20
add 20 to both sides
10x+30 = 16x
subtract 10x from both sides
30 = 26x
divide by 26 on both sides
[tex]\frac{30}{26} = x[/tex]
simplify
[tex]\frac{15}{13}[/tex]
Substitute the x value
2 of the sides are 2x+3
so
[tex]2(\frac{15}{13} ) + 3[/tex]
[tex]\frac{30}{13} + \frac{3}{1}[/tex]
[tex]\frac{33}{13}[/tex]
or 2.5
other sides
[tex]3(\frac{15}{13} ) + 2[/tex]
[tex]\frac{45}{13} + \frac{2}{1}[/tex]
[tex]\frac{47}{13}[/tex] or 3.6
That's all I can say for now! Hope this helps and a thank won't hurt! :)

Farmer David has 24 chickens. He gives a quarter of the chickens to Sally and a sixth of the chickens to Patience. How many chickens does he have left?
Answer:
14
Step-by-step explanation:
One fourth is 6 and one with is 4. So 4+6=10.24-10=14.
Answer:
14
Step-by-step explanation:
If you have 24 chickens, a quarter of 24 is 6. Then, a sixth of 24 is 4. 6+4=10. 24-10=14. So, he would have 14 chickens left.

Answer:
1. = station A
because 15 gallons = 0.75 discount at B but station A has a 1.50 discount at 15 gallons
Step-by-step explanation:
2. for satation B you have to read the graph
but for station A it is unclear on the graph
a way to work it out is that you know that 10= 1.00 so 12 = 1.2
( divide 12 by 10 )
station B = discount for 12 gallons = 0.6
but Station A = discount for 12 gallons = 1.2
the difference is
1.2 - 0.6 = 0.6 discount

Answer:
x = -7
Step-by-step explanation:
These angles are supplementary because they're same side interior angles. Supplementary means the 2 angles add up to 180
Equation:
x + 67 + x + 127 = 180
2x + 194 = 180
2x = 180 - 194
2x = -14
x = -14/2
x = -7
Hi how u doin ?
[tex](x + 67) + (x + 127) = 180[/tex]
[tex]x + x + 67 + 127 = 180[/tex]
[tex]2x + 194 = 180[/tex]
Subtract both sides 194
[tex]2x + 194 - 194 = 180 - 194[/tex]
[tex]2x = - 14[/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{ - 14}{2} \\ [/tex]
[tex]x = - 7[/tex]

52,300,000 in scientific rotation
Answer:
-5.230,0000
Step-by-step explanation:
Your number in decimal form is -52,300,000 . The negative sign remains unchanged. To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, -52,300,000 becomes -5.230,0000

F - 38
G - 38
H - 142
Step-by-step explanation:
It's been a while since I've done these so please don't judge
Answer:
Well this is pretty simple
Parralel lines cut by a transversal.
So we have one measurement of 142 which is a
A and B are supplementary (When added up you get 180 degrees)
So basically to find that you can do this
180-142=38
So B is 38
We can now use vertical angles.
A and D are vertical and vertical angles are congruent (equal)
d is 142
B and c are congruent
B is 38 so C is also 38
Now We find EGHF
Techcinally we can just do what i would do which is draw and x between the vertical angles
So if drawn an ”X” you can see the sam exact pattern as for ABCD
Which in this case E is 142
H is 142
F is 38
G is 38
If done the hard way you can use altenrate/same side (interior exterior)/ Corresponing angles.
So Here’s what you need to know
Alternate interior and exterior are equal
Correspnding angles are equal
Same side are supplementary
Thats all you need to know.
Interior is basically BD and EG
Exterior is AC and FH
Correspnding are basically same sides but one is ont he inside and one is on the outside
Ex:
A and E
B and F
C and G
D and H
Same side is EXACLTY what is sounds like, the same side but everything has to be either interior or exterior
(Interior) B and E
(Interior) D and G
(Exterior) A and F
(Exteiror) C and H
Final answers:
A- 142
B- 38
C- 38
D- 142
E- 142
F- 38
G- 38
H- 142

Using the digits 1 to 9 at most one time each fill in the boxes to create an equation that has a negative solution

Answer:
[4]x+[8]=[1×]+2
Step-by-step explanation:
x will be negative now that the more x you have the higher your number will have to be.
The requried, x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution as x = -3.5.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
One possible solution is,
[1]x + [2] = [3]x + [9]
To see that this equation has a negative solution, we can rearrange it to get:
x + 2 = 3x + 9
x - 3x = 9 - 2
-2x = 7
x = -3.5
Since x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution.
