Find the value of the variable that makes the equation true 3x-11=-2x+19
Answer:
x = 6
Step-by-step explanation:
Given
3x - 11 = - 2x + 19 ( add 2x to both sides )
5x - 11 = 19 ( add 11 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6

Step-by-step explanation: :)
Find the greatest solution to the following system of equations. Write as x= ?
y=x^2+x-2 and y=-x+1
Answer:
we have x=1, y=0 and x=-3, y=4
Step-by-step explanation:
We need to solve the equations: [tex]y=x^2+x-2 \ and \ y=-x+1[/tex]
Let:
[tex]y=x^2+x-2--eq(1)\\ y=-x+1---eq(2)[/tex]
Putting value of eq(2) into eq(1)
[tex]-x+1=x^2+x-2\\Solving:\\x^2+x-2+x-1=0\\x^2+2x-3=0\\Factorising:\\x^2+3x-x-3=0\\x(x+3)-1(x+3)=0\\(x-1)(x+3)=0\\x-1=0 \ or \ x+3=0\\x=1 \ or \ x=-3[/tex]
Now finding values of y for x=1 and x=-3
[tex]For \ x=1, \\y=-x+1 \\y=-1+1 \\y=0\\For \ x=-3\\ y=-x+1\\y=-(-3)+1 \\y=3+1\\y=4[/tex]
So, we have x=1, y=0 and x=-3, y=4

What is the mDEF? plz help
Answer:
m∠DEF = 148°
Step-by-step explanation:
The total sum of angles inside a triangle is 180°
m∠FDE + m∠EFD + m∠DEF = 180°
We can also see that because two sides are congruent, their angles are also congruent, so we can solve for x
m∠FDE = m∠EFD
2x + 8 = 3x + 4; subtract 2x from both sides
8 = x + 4; subtract 4 from both sides
x = 4; now we can substitute into equations
m∠FDE = m∠EFD;
2(4) + 8 = 3(4) + 4
8 + 8 = 12 + 4; 16=16; therefore = m∠FDE = m∠EFD = 16
To solve for m∠DEF
m∠FDE + m∠EFD + m∠DEF = 180°
16 + 16 + m∠DEF = 180
m∠DEF = 148°

mrs.cook wants you to send a package to her friend and in spain. it costs 3$ for the packaging and then $0.20 for each ounce if she paid $15.60 how heavy was the package? be sure to define your variable and show your equation
Answer:
assuming you want the answer in ounces still, its 63 ounces
Step-by-step explanation:
total = $3 + 0.20x
15.60 = 3 + 0.20x
12.60 = 0.20x
63 = x
Answer:
63 ounces
Step-by-step explanation:
0.20x+3= 15.60
-3 -3
0.20x= 12.60
0.20 0.20
x= 63
7x + 6y = 10

CAN SOMEONE HELP IM SO CUNFUSED
Answer:
m = 1/3
Step-by-step explanation:
Answer:
Slope can be indentified by looking t how much a point has gone up/down and to the right/left. An example can be a point at 0,0 and a point at 1,1
from 0,0 to 1,1 it goes 1 units up and 1 unit right. Therefore the slope is 1/1 or just 1.
So to find this answer we could graph the points or just find out how many units it takes from going up/down and right/left to get from (-2, 1) to (7, 4)
From -2 to 7 is 9 units and from 1 to4 is 3 units
The slope is rise/run meaning the distance u moved in height over he distance moved right/left. Therefore the slope is 3/9 which is 1/3

Two eighth-grade classes are selling chocolate bars to raise money for an end-of-year field trip. One class is selling chocolate bars for $3.00 each and has already raised $275.00. The other class is selling chocolate bars for $3.50 each and has already raised $250.00. Which equation can be used to calculate c, the number of additional chocolate bars each class needs to sell, so that the total amount raised is the same for both classes?
Answer:
Step-by-step explanation:
you add both $275.00 and $250.00 ($525.00) then and $3.00 and $3.50 ($6.50) then divide $525.00 by $6.50 and then you answer would be $88.00
so c = $88.00
Answer:
3.50c + 250.00 = 3.00c + 275.00

What does it mean if (2, 20) is a solution of y = 10x and x +y = 22 ?
2, 20) makes exactly one of the equations true.
(2, 20) makes at least one of the equations true.
(2, 20) makes neither equation true.
(2, 20) makes both equations true.
Answer:
(2, 20) makes both equations true
Step-by-step explanation:
If a point is a solution for 2 equations, that means that it makes both equations true.
So, since (2, 20) is a solution to both y = 10x and x + y = 22, that means it makes both of the equations true.

rearrange 24(x-y)=5x-3 to make y the subject
Answer:
y = [tex]\frac{19x+3}{24}[/tex]
Step-by-step explanation:
Given
24(x - y) = 5x - 3 ← distribute parenthesis on left side
24x - 24y = 5x - 3 ( subtract 24x from both sides )
- 24y = - 19x - 3 ( multiply through by - 1 to clear the leading negative )
24y = 19x + 3 ( divide both sides by 24 )
y = [tex]\frac{19x+3}{24}[/tex]

During geometry class, students are told that ΔTSR ≅ ΔUSV. Marcus states that ΔTSR is mapped to ΔUSV by performing a rotation about point S. Sam states that ΔTSR is mapped to ΔUSV by a reflection across the line that goes through point S. Determine if either student is correct.
Answer: Marcus is correct.
i got it right on Edge2020
Step-by-step explanation:
Transformation involves changing the position of a shape through translation, dilation, rotation and reflection.
Marcus's claim is correct.
The triangles are given as: ΔTSR and ΔUSV
By comparison, we can see that point S is on both triangles, and this point on both triangles corresponds.
So, to map ΔTSR to ΔUSV, then ΔTSR must be rotated about point S to ΔUSV or rotate ΔUSV about point S to ΔTSR.
Hence, Marcus is correct, and Sam is not.
