Answer:
x=15/16
Step-by-step explanation:
Let's solve your equation step-by-step.
6−34x+13=12x+5
6+−34x+13=12x+5
Multiply all terms by x and cancel:
6x+−34+1x3=12+5x
193x+−34=5x+12(Simplify both sides of the equation)
193x+−34−5x=5x+12−5x(Subtract 5x from both sides)
43x+−34=12
43x+−34+34=12+34(Add 3/4 to both sides)
43x=54
(34)*(43x)=(34)*(54)(Multiply both sides by 3/4)
x=1516
Check answers. (Plug them in to make sure they work.)
x=1516(Works in original equation)

Find the equation of the line that passes through the point (-2,-7) that has a slope of 3
Answer:
The answer is
y = 3x -1Step-by-step explanation:
To find an equation of a linewhen given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1) \\ [/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-2,-7) and slope 3 is
The equation of the line is
[tex]y + 7 = 3(x + 2) \\ y + 7 = 3x + 6 \\ y = 3x + 6 - 7[/tex]
We have the final answer as
y = 3x - 1Hope this helps you
The Oakville High School Marching Band sold gift wrap to earn money for a band trip. Solid color gift wrap sells for $3.50 per roll and printed gift wrap sells for $5 per roll. The band needs to earn $2,500 for an upcoming competition. If the band sells 325 rolls of printed paper, write and solve a linear equation to find the number of sold paper they must sell
Let, number of solid color gift sold is x and printed gift wrap is y.
Also, number of printed paper sold , 325.
Expressing, it in mathematical equation :
y = 325 ....... 1)
Also, The band needs to earn $2,500 for an upcoming competition.
So ,
3.5x + 5y = 2500 ....... 2)
Solving equation 1 and 2 :
3.5x + 5(325) = 2500
3.5x = 2500 - 1625
3.5x = 875
x = 250
Therefore, number of solid paper they must sell is 250.
Hence, this is the required solution.

find the inverse (6,-14),(7,6),(7,-6),(19,-5)
Answer:
Step-by-step explanation:
For instance, x = x/1. The reciprocal of a number is this fraction flipped upside down. In other words, the reciprocal has the original fraction's bottom number—or denominator—on top and the top number—or numerator—on the bottom. So the reciprocal of 6 is 1/6 because 6 = 6/1 and 1/6 is the inverse of 6/1.
∠A and \angle B∠B are vertical angles. If m\angle A=(3x-9)^{\circ}∠A=(3x−9) ∘ and m\angle B=(x+3)^{\circ}∠B=(x+3) ∘ , then find the value of x.
Answer:
x = 6
Step-by-step explanation:
Vertical angles are congruent, thus
∠ A = ∠ B , substitute values
3x - 9 = x + 3 ( subtract x from both sides )
2x - 9 = 3 ( add 9 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Answer:
x = -3
Step-by-step explanation:
ignore outside work find all missing variables and measures of each angle**
Answer:
y= 18
42°
x=60
60°
Step-by-step explanation:
because of vertical angles theorem, 2y+6=8y-102
add 102 to 6
2y+108=8y
subtract 2y from 8y
108=6y
y= 18
now plug in to each equation for angles
2(18)+6= 42°
8(18)-102= 42°
now I dont think you can solve for x and y in an equation. 3x=180
divide 3 from 180
180/3 = 60
x=60
plug 60 into 3x=180 and get 180°.
angles for x are 180°
if I'm incorrect on the X value someone please correct me.

Answer:
89.44
Step-by-step explanation:
using the Pythagorean Theorem: [tex]a^{2} +b^{2}=c^{2}[/tex]
[tex]80^{2} +b^{2} =120^{2} \\6400+b^{2} =14400\\b^{2} = 8000\\b = 40\sqrt{5}[/tex]
120 is the hypotenuse so it would be c in the equation.
To solve, I simplified and isolated the variable. I got the square root of 8000 simplified (but idk how to write that out lol)
This answer is closest to 89.44

I have a challenge for someone: What is the area of the shaded area if the perimeter is 68 (fake answers will be reported)
Answer:
126.14 in²Step-by-step explanation:
Given
Rectangle with sides of 20 in and x+2 in and perimeter of 68 inPerimeter = 2(l + w)
l = 20 in, w = x + 2 in, P = 68 inSubstitute values in perimeter formula
68 = 2(20 + x + 2)34 = x + 22x = 34 - 22x = 12 inThen, the value of width is
w = 12 + 2 = 14 inArea of rectangle
A = lw = 20*14 = 280 in²Area of circle
A = πr² = 3.14*7² = 153.86Shaded area
280 - 153.86 = 126.14 in²Answer:
126.14in²
Step-by-step explanation:
P = 2w + 2l
68 = 2(x + 2) + 2(20)
68 = 2x + 4 + 40
68 = 2x + 44
24 = 2x
12 = x
x + 2
12 + 2
14 (width)
14 * 20
280in² (area of rectangle)
A = πr²
A = π(7)²
A = 49π
A = 153.86 (area of circle)
280 - 153.86
126.14 (area of shaded region)

What does 3x+2=-2+x Equal? (solve for X, Angles)
Answer:
x = -2
Step-by-step explanation:
3x + 2 = -2 + x Subtract x from both sides of the equation
2x + 2 = -2 Subtract 2 from both sides of the equation
2x = -4 Divide 2 from both sides of the equation
x = -2 <---- This is our answer

If the area of a square desk is 324 square inches, how long is each side?
To find area, you multiply base x height. So to find base and height, you find the square root of 324(because this is a square). I am in 8th grade and I don't really know how to find the square root so I googled it(sorry).
sqrt of 324 is 18.

Milk and cream I miss together for recipe the total volume I make use one cup with the milk contains 2% cream contains 18% bad Milk and creamer mix to gather for a recipe for total volume on to make use one cup if the milk contains 2% fat and gross cream contains 18% that makes you contain 6% that how much cream is in the measure
Answer:
25% or ¼
Step-by-step explanation:
We are told that the milk contains 2% (0.02) fat and gross cream contains 18%(0.18) that makes you contain 6%(0.06)
Let x be the volume of the cream in the mixture.
Since 1 cup, then volume of milk in the mixture will be; (1 - x)
Setting up the equation, we have;
0.18x + 0.02(1 - x) = 0.06
0.18x + 0.02 - 0.02x = 0.06
0.16x = 0.06 - 0.02
x = 0.04/0.16
x = 0.25
Converting to percentage gives; 25% or ¼
