The solution of the linear equations 2x + y = 8 and y = 3x - 2 will be (2, 4).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equations are given below.
2x + y = 8 ...1
y = 3x - 2 ...2
From equations 1 and 2, then the value of the variable 'x' is calculated as,
2x + 3x - 2 = 8
5x = 10
x = 2
Then the value of the variable 'y' will be calculated as,
y = 3(2) - 2
y = 6 - 2
y = 4
The solution of the linear equations 2x + y = 8 and y = 3x - 2 will be (2, 4).

I just need the inequality/equation please!
Stephanie is saving money to buy a computer next year. So far she has saved $200. Write an inequality to show how much she needs to save each month for the next year so she has at least $1200 to spend on the computer, then solve the inequality.
Let x represent the amount that she needs to save each month for the next year.
Stephanie is saving money to buy a new computer. So far she has saved $200. This means that the total amount that she would have saved in y months is
200 + xy
Since there are 12 months in a year,
an inequality to show how much she needs to save each month for the next year so she has at least $1200 to spend on the computer is
200 + 12x ≥ 1200
12x ≥ 1200 - 200
12x ≥ 1000
x ≥ 1000/12
x ≥ 83.33

i cant solve this help –8x + 15 < 71
Answer:
x > -7
Step-by-step explanation:
Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction
First, subtract 15 from both sides:
-8x + 15 (-15) < 71 (-15)
-8x < 71 - 15
-8x < 56
Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:
(-8x)/-8 < (56)/-8
x < (56)/-8
x > -7
x > -7 is your answer.
~
Answer:
Any number greater than but excluding -7.
Step-by-step explanation:
-8x + 15 < 71
-8x < 71 - 15
-8x < 56
56 divided by -8 = -7
So, that means anything greater than -7 would result in a lower number than 71.

Kelly and Brandon have a combined age of 32.
They have an age difference of 6 (Kelly is older).
Write a system of equations to find out how old Kelly is
and how old Brandon is.
Answer:
Kelly is 19; Brandon is 13
Step-by-step explanation:
k + b = 32. Also: k = b + 6.
Substituting b + 6 for k in the first equation, we get b + 6 + b = 32, or
2b = 26. Then b must be 13, and k must be 13 + 6, or 19.
Kelly is 19; Brandon is 13.
Answer:
Brandon is 13, Kelly is 19.
Step-by-step explanation:
Let's set up our equations.
Kelly and Brandon have a combined age of 32.
K + B = 32
They have an age difference of 6. Kelly is older.
K - B = 6
Let's shift the equation around a little.
K - B = 6
Add B to both sides.
K = B + 6
Now let's plug K into our first equation.
K + B = 32
(B + 6) + B = 32
Combine like terms.
2B + 6 = 32
2B = 26
Divide both sides by 2.
B = 13
Now that we know Brandon is 13, we can find Kelly's age.
K + B = 32
K + 13 = 32
K = 19
Kelly is 19.
Hope this helps!
Ryan says that a rectangle is a square because it has 4 right angles. Addy says that a rhombus is a square because it has 4 equal sides. Part A Who is correct? A. Only Addy B. Only Ryan C. Both Ryan and Addy D. Neither Ryan nor Addy Part B How are rectangles and squares related? Use the drop-down menus to complete the explanation. All Choose... are Choose... , but only Choose... with 4 equal sides are Choose...
Answer:
D. Neither Ryan nor Addy
Step-by-step explanation:
Square:
A square is a quadrilateral that has equal sides and all angles equal to 90 degrees.
Rectangle:
A rectangles is a quadrilateral that has equal or unequal sides and all angles equal to 90 degrees. All rectangles are not squares.
Rhombus:
A rhombus is a quadrilateral that has equal sides and all angles may or may not be equal to 90 degrees. All squares are rhombus. But all rhombus are not squares.
As both Ryan and Addy have missed out one property of square therefore both of them are incorrect.

A jacket has an original price tag of $68. The jacket is on sale for 80% of its original price. What is the sale price of the jacket?
Answer:
I believe it is 54.40$
Step-by-step explanation:
I think weird. so
68 divided by 5 which will give you 20%(13.6) then multiply by 4 which is 80%(54.4)
Answer:
Sale price = $13.6
Step-by-step explanation:
The 80% cost of the jacket is,
→ (68/100) × 80
→ 0.68 × 80
→ $54.4
Now the sale price will be,
→ 100% - 80%
→ 68 - 54.4
→ $13.6
Hence, sale price is $13.6.

Answer:
The area of the polygon is 624.5 square feet.
Step-by-step explanation:
The total area of the figure ([tex]A[/tex]), in square feet, is the sum of the areas of two triangles and a rectangle, that is:
[tex]A = A_{I}+A_{II}+A_{III}[/tex] (1)
Where:
[tex]A_{I}[/tex] - Area of the big triangle, in square feet.
[tex]A_{II}[/tex] - Area of the small triangle, in square feet.
[tex]A_{III}[/tex] - Area of the rectangle, in square feet.
Then, we expand the formula by using all dimensions presented in the image attached:
[tex]A = \frac{1}{2}\cdot (25\,ft)\cdot (33\,ft-8\,ft) + \frac{1}{2}\cdot (8\,ft)\cdot (43\,ft-35\,ft) + (35\,ft)\cdot (8\,ft)[/tex]
[tex]A = 624.5\,ft^{2}[/tex]
The area of the polygon is 624.5 square feet.

can be written as a single fraction in the form ax+b/5x(x+2) where a and b are integers.
Work out the value of a and the value of b.
a =
b=
b) Factorise 4(x + y) + (x + y)^2
The value of a and b are a=8 and b=6 respectively.
What is factorization?factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.
We are given the expression as
3/(5x) + 1/(x+2)
We have to multiply 3 by (x+2) and 1 by (5x)
3(x+2) = 3x+2 and 1(5x)= 5x
Now we have
3x+6/(5x)(x+2)
5x/(5x)(x+2)
Now adding the numerators gives us
8x+6/(5x)(x+2)
Therefore a=8 and b=6

Answer:
x = 124°

Jackie deposits $2,050 into an account that pays 6.8% interest compounded annually. How much will be in the account (to the nearest dollar) after 6 years?
Answer:
$2091 (exact answer is $2090.80)
Step-by-step explanation:
2050 × 6.8% = 6.8
So, interest will add an extra $6.80 to his account
6.8 × 6 = 40.8
So, after 6 years, interest will make him an additional $40.80.
Add 40.80 to his original amount of money.
2050 + 40.8 = 2090.80
Round it up to the nearest dollar.
$2091
