What is the value of the x variable in the solution to the following system of equations? (5 points)
3x + 2y = 8
2x + 3y = 2
a.) 4
b.) −2
c.) x can be any number as there are infinitely many solutions to this system
d.) There is no x value as there is no solution to this system.
Please and thank you!!
Answer:
x = 4
Step-by-step explanation:
To find x, we can use elimination:
[tex]3(3x+2y)=3\times8[/tex] (times 3 on both sides so [tex]2y[/tex] becomes 6y)
[tex]9x+6y=24[/tex]
[tex]2(2x+3y)=2\times2[/tex] (times 2 on both sides so [tex]3y[/tex] becomes 6y)
[tex]4x+6y=4[/tex]
[tex]9x+6y-(4x+6y)=24-4[/tex] (This eliminates the variable [tex]y[/tex] so we are left with only one variable: [tex]x[/tex])
[tex]5x=20[/tex]
[tex]x=4[/tex]
Option a is correct.
Carpect costs $16 a square foot. A rectangular floor is 16 feet long by 14 feet wide. How much would it cost to carpet the floor?
Answer:
$3584
Step-by-step explanation:
- because its a rectangle, the area of the floor is length*width, so 16*14 = 224 square feet
- one square foot is $16, so 224 sqaure feet are 224*16
= 3584
Answer:
$3584
Step-by-step explanation:
To find square feet, multiply the length measurement in feet by the width measurement in feet.
16 x 14 = 224
Now, find how much it costs, there is 224 square feet in total so since it's 16 dollar for every square feet.
224 x 16 = 3584

Which statement correctly describes the relationship between △JKL and △J′K′L′?
△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a reflection across the x-axis, which is a rigid motion.
△JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.
△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a translation 5 units up, which is a rigid motion.
△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a rotation of 90° counterclockwise about the origin, which is a rigid motion.
Answer:
Is not congruent because there is not sequence of rigid motions

Sandy Island Beach is building a new Snack Shack based on a scale drawing that is 20 centimeters by 60 centimeters and uses the scale 1 cm : 1.5 m.
Answer:
30m by 90m
Step-by-step explanation:
20 x 1 = 20
20 x .5 = 10
20 + 10 = 30
60 x 1 = 60
60 x .5 = 30
60 + 30 = 90
HELP ASAP WILL MARK BRAINLIEST
Answer:
D
Step-by-step explanation:
Since James gave Malcolm a head start of 20 feet, Malcolm's line should start at 20 feet. So that rules out A. They were obviously going further so they went more feet, So C is ruled out because it shows them not moving, plus James didn't get a 15 foot head start which is what the C graph shows. Finally it's not B because if you look at the key at the bottom of every graph, it says that Malcolm is the dotted line, and B shows James getting a 20 foot head start, not Malcolm.

350 calories
693 calories
1,386 calories
Answer:
1,386 calories
Step-by-step explanation:
The 1,350 is not important- this is just the weight of the bag.This is a ratio problem, so we need to compare 9 and 6,237 to 2 and _.9/2 = 4.5, so you would divide 6237/4.5. This is 1386 calories- the answer.help pls :)))) algebra i’ll give brainliest
Answer:
There is one solution, x=2
Step-by-step explanation:
1/2x+6=4x-1
subtract 6 from both sides
1/2x=4x-7
subtract 4x from both sides
-7/2x=-7
multiply both sides by 2
-7x=-14
divide both sides by -7
x=2
what does 1270 round to round to nearest hundred
Answer:
1300
Step-by-step explanation:
round = more. If its lessthan 49, round down. 50 or up = round up
Hope this helps plz mark brainliest :D
1300. The hundred in this number would be 270; look at the number that comes before the hundred [2], which would be 7 [70]. Since that is above five, round up, therefore leaving you with 300 [1300].

magine you have two friends, Jose and Jessie. Jose is a gifted athlete, but Jessie lives a sedentary lifestyle. Jose and Jessie both ask you to develop an action plan to improve their flexibility. How would your advice differ for Jose and Jessie? Consider specific exercises, frequency of exercise, level of conditioning, levels of flexibility, goal setting, and other important factors in your response.
Answer:
First of all, Jose and Jessie have a big difference when it comes to physical health and condition. Jessie is not able to perform the same exercises as Jose, neither the same intensity, and they cannot have the same goal.
So, for Jessie improve her flexibility we have to consider low intensity exercises, specifically, aerobic exercises, like walking, dancing, jogging at a low pace, pilates and yoga. Jessie, as a sedentary person most consider to do those aerobic activities three times per week, at least 30 minutes to ensure that she is demanding enough effort from her body, but all at low intensity.
