I hope you got your answer.
solve by substitution y - 3x = 2, x - 2y = -6
y=2+3x
putting value on second equation we get..
x-2(2+3x)=-6
x-4+6x=-6
7x=-2
×=-2/7
& y=2+3(2/7)
y=2+0.87
y=2.87..Ans..
Answer:
x= 2/5
y= 3.2
Step-by-step explanation:
y-3x=2
y=3x+2
replace y with 3x+2 in second equation;
x-2(3x+2)= -6
x- (6x+4)= -6
x-6x-4= -6
-5x-4+4=-6+4
-5x= -2
x= 2/5
y=3x+2
y=(3×2/5) +2
y= 3.2

0=1-2y+14x what is the slope and the y-intercept
Answer:
slope: 7
y-intercept: 1/2
Step-by-step explanation:
Put it into the form y = mx + b where m is the slope and b will be the y-intercept. (For example, in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2).
[tex]0=1-2y+14x\\2y=1+14x\\2y = 14x+ 1\\y = 7x + 1/2[/tex]
So you know that m = 7, so the slope is 7
and
b = 1/2, so the y-intercept is 1/2.
Simplify the expression.

1st one x=245°
2nd one x= 250
Step-by-step explanation:
hope its correct
hope u find it helpful
Answer:
x = 245 and x = 20
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540
25 + 112 + 100 + 58 + x = 540
295 + x = 540 ( subtract 295 from both sides )
x = 245
---------------------------------------------------------------
5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540
25x + 40 = 540 ( subtract 40 from both sides )
25x = 500 ( divide both sides by 25 )
x = 20

(PLEASE ANSWER FOR BRAINILEST ASAP!!) (EXPLAIN!!) 3 boxes all way the same amount. All together they weigh 54.3 pounds. How much does 1 box weigh?
Answer:
Step-by-step explanation:
Let B = the weight of box B
Let 2B = the weight of box A
Let 2B + 30 = the weight of box C
B + 2B + 2B + 30 = 640
5B = 610
B = 122 pounds, weight of box B
2B = 2(122) = 244 pounds, weight of box A
2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

I’ve been stuck on this for a few minutes. I’m not really sure what to do..
Answer:
Step-by-step explanation:
You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.
You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.
That leaves you with one unknown angle. ? = 180°-40°-55° = 85°
6. A quadrilateral ABCD is drawn to circumscribe a circle. Prove that AB + CD = AD + BC.
Answer:
i not sure sorry ..........
in triangle ABC with vertices A(4,5),B(-2,1) and C(0,3),E and F are midpoints of sides AB and AC resp . then, find coordinates of E and F
Answer:
The answer is
E=(1, 3)
F=(2,4)
Step-by-step explanation:
When E is midpoint of AB
Then
[tex]e = ( \frac{4 + ( - 2)}{2} . \frac{5 + 1}{2} ) \\ = (1.3)[/tex]
By this way we can find F
[tex]f = ( \frac{4 + 0}{2} . \frac{5 + 3}{2} ) \\ = (2.4)[/tex]

You measure 3 inches between your house and the movie theater. How many miles is in from your house to the movie theater?
Answer:
4.734 * 10^-5 miles
Step-by-step explanation:
Given that:
Distance between House to movie theater = 3 inches
Expressing the distance in miles :

**please let me know if this was wrong**
Answer:
1) In the second step, it was supposed to multiply 9 and 2 and 36 by 3 instead of adding 9 and 3 to each other because multiplication and division comes before adding, according to pemdas.
2) In the second step, they were supposed to multiply 6 and 4 instead of subtracting 27 and 6 because multiplication comes before subtraction, according to pemdas.
3)

Step-by-step explanation:
Section 1: Explain the error in each problem below.1) Pemdas says multiplication and division comes before adding, so you must solve the multiplication in the problem first before the addition.
2) Again, as pemdas says, multiplication comes first before subtraction, so you must solve the multiplication in the problem first before the sutraction.
Section 2: Simplify the following expressions.3) (43 - 20) - 2 · 5
Pemdas says to solve the parenthesis first.
43 - 20 = 2323 - 2 · 5Now multiplication comes next (because there's no exponents).
2 · 5 = 1023 - 10Now subtraction.
23 - 10 = 134) 81 ÷ (13 - 4)
Pemdas says to solve the parenthesis first.
13 - 4 = 981 ÷ 9Now division comes next.
81 ÷ 9 = 95) 7 · 8 - 3 · 6 + 1
Pemdas says to solve the multiplication first.
7 · 8 = 56 3 · 6 = 1856 - 18 + 1Now subtraction and addition.
