what is 3x-2-7x = 10x + 4?
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x−2−7x=10x+4
3x+−2+−7x=10x+4
(3x+−7x)+(−2)=10x+4(Combine Like Terms)
−4x+−2=10x+4
−4x−2=10x+4
Step 2: Subtract 10x from both sides.
−4x−2−10x=10x+4−10x
−14x−2=4
Step 3: Add 2 to both sides.
−14x−2+2=4+2
−14x=6
Step 4: Divide both sides by -14.
−14x−14=6−14

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3x-2-7x = 10x + 4
Now, solving for x
3x-2-7x = 10x + 4
-4x - 2= 10x + 4
-4x - 10x = 4 + 2
-14x = 6
x= -6/14
c= -3/7
Hence, the value of x is -3/7.

Find the area of the shape.
You go shopping at a local department store with your friend and cousin. You buy one pair of jeans, four pairs of shorts, and two shirts for $84. Your friend buys two pairs of jeans, one pair of shorts and three shirts for $76. Your cousin buys one pair of jeans, two pairs of shorts and one shirt for $52. Find the cost of one pair of shorts.
Answer:
So, cost of 1 pair of shorts =$12
Step-by-step explanation:
Let cost of 1 pair of jeans =x
Cost 1pair of shorts =y
cost of 1 pair of shirts=z
We can set up equations as
x+4 y+2 z=84
2 x+1 y+3 z=76
x+2 y+z=52
Solve the equations for y.
Take first and second equations multiply first equation by -2 and add it with second equation.
-2 x-8 y-4 z=-168
2 x+1 y+3 z=76
Add them, it gives -7 y-z =-92
Now, take second and third equations, multiply the third equation by -2 then add them together.
2 x +1 y +3 z =76
-2 x-4 y-2 z=-104
Add them together,
-3 y +z =-28
Now, take the -7 y -z =-92 and -3 y +z =-28
Add the equations
-10 y = -120
Divide both sides by -10
y =12.
So, cost of 1 pair of shorts =$12
z=8

What is m∠PQR?
The PS is line segment. Q is the point between segments PS. QR is another line segment passes through segment PS. The angle PQR is (3x + 5) degree and angle SQR is (x + 3) degree.
Answer: m∠PQR = 134°
Step-by-step explanation:
Given: PS is line segment. Q is the point between segment PS. QR is another line segment passes through segment PS.
That means ∠PQR and ∠SQR are linear pair [Linear pair is a pair of two angles made on one line and their sum is 180°]
⇒ ∠PQR + ∠SQR = 180° (i)
Since, ∠PQR is (3x + 5)° and ∠ SQR is (x + 3)° [given]
Put this in (i), we get
(3x + 5)° + (x + 3)° = 180°
⇒ 3x + 5 + x + 3 = 180
⇒ 4 x + 8 = 180
⇒ 4 x = 180-8
⇒ 4 x = 172
Divide both sides by 4
⇒ x= 43
So, ∠PQR= (3(43) + 5)° = 134°
Hence, m∠PQR = 134°
The measure of m ∠PQR is 134 degrees.
GivenPS is a line segment.
Q is the point between segment PS.
QR is another line segment that passes through segment PS.
Which property of the triangle is used to solve the value of x?The sum of two angles made on one line is equal to 180 degrees.
[tex]\angle \rm PQR + \angle SQR = 180[/tex]
Where the angle QPR is (3x + 5) degree and angle SQR is (x + 3) degree.
Substitute all the values in the equation
[tex]\angle \rm PQR + \angle SQR = 180\\\\(3x+5) + (x+3) =180\\\\3x+5+x+3=180\\\\4x+8=180\\\\4x=180-8\\\\4x=172\\\\x = \dfrac{172}{4}\\\\x =43[/tex]
The value of x is 43 degrees.
Therefore,
The measure of m ∠PQR is;
[tex]\rm m \angle PQR = 3x+5 = 3(43) + 5= 129+5=134[/tex]
Hence, the measure of m ∠PQR is 134 degrees.
