Solve the equation 3x-1 = -7
Answer: x = -2
Step-by-step explanation:
first, we move the constant to the right.
3x = -7 + 1
then, we calculate that.
3x = -6
finally, we divide both sides.
x = -2
The solution to the equation 3x - 1 = -7 is x = -2.
To solve the equation 3x - 1 = -7, we need to isolate the variable x on one side of the equation.
Here are the steps to solve it:
Step 1: Start with the given equation: 3x - 1 = -7.
Step 2: To eliminate the constant term (-1) on the left side, we can add 1 to both sides of the equation:
3x - 1 + 1 = -7 + 1.
Simplifying, we get: 3x = -6.
Step 3: Now, we want to isolate x, so we need to get rid of the coefficient 3 in front of x.
We can do this by dividing both sides of the equation by 3:
(3x)/3 = (-6)/3.
Simplifying further, we have: x = -2.
Step 4: We have found the solution to the equation: x = -2.
Therefore, the solution to the equation 3x - 1 = -7 is x = -2.

Given the area of a circle to be 10 inches^2 what is the radius and the diameter the circumference
Answer:
Radius = 1.78 inches
Diameter = 3.56 inches
Circumference = 11.18 inches
Step-by-step explanation:
Area of circle = 10 inches square
[tex]\pi r^2 = 10\\r^2 = \frac{10}{3.14}\\r^2 = 3.18\\\sqrt{r^2}=\sqrt{3.18}\\r=1.78[/tex]
Radius = 1.78 inches
Diameter = 2r = 2(1.78) = 3.56 inches
Circumference = 2πr = 2*3.14*1.78 = 11.18 inches

help pls? If mF= 109*, mQ=122*, mR=44, find mJ
Answer:
∠J=85°
Step-by-step explanation:
Theory to know when answering this question:
1. The sum of the angles in a quadrilateral (shape with four sides) is 360°
2. Similar shapes have the same angles
Point 1 tells us that ∠P+∠Q+∠S+∠R=360
Point 2 tells us that ∠F=∠P, ∠G=∠Q, ∠J=∠S, and ∠H=∠R.
∴∠F+∠Q+∠J+∠R=360
109+122+∠J+44=360
∠J=360-275=85°
A singles tennis court measures (8x – 2) ft long and (3x – 3) ft wide.Which expression represents the area of the court?
Answer:
The expression that represents the area of the court is: [tex]24x^2 - 30x + 6[/tex]
Step-by-step explanation:
Area of a rectangle:
A rectangle has length l and width w. The area of a rectangle is:
[tex]A = lw[/tex]
A singles tennis court measures (8x – 2) ft long and (3x – 3) ft wide.
This means that [tex]l = 8x - 2, w = 3x - 3[/tex]
Which expression represents the area of the court?
The tennis court is rectangular, so
[tex]A = lw = (8x - 2)(3x - 3) = 24x^2 - 24x - 6x + 6 = 24x^2 - 30x + 6[/tex]
The expression that represents the area of the court is: [tex]24x^2 - 30x + 6[/tex]
You have a loan for $200,000 at 8.5% annual simple interest.what is your monthly interest payment
Answer:
~1467

Answer:
approx 72 feet
Step-by-step explanation:
the left and bottom sides of the quadrilateral are easy to see that their sum is 15 + 20 or 35
however, from (40, 30) to (45, 40) you can use the distance formula
d = √(y - y)² + (x - x)²
d = √10² + 5²
d = √125 which is approx 11.1
from (20, 40) to (45, 40) you get:
d = √5² + 25²
d = √650 which is approx 25.5

mr chowdhary purchased a house for rs 6.1 lakh and spent 30000 on its repairs. he then sold it rs 8 lakh. find his gain percent
Given:
Purchasing price = 6.1 lakh
Amount spent of repair = 30000
Selling price = 8 lakh
To find:
The gain percentage.
Solution:
We have,
Purchasing price = 6.1 lakh
Amount spent of repair = 30000 = 0.3 lakh
So, total cost price is
[tex]C.P.=6.1+0.3[/tex]
[tex]C.P.=6.4[/tex]
The total cost price is 6.4.
Selling price(S.P.) = 8 lakh
Now,
[tex]Gain\%=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]
[tex]Gain\%=\dfrac{8.0-6.4}{6.4}\times 100[/tex]
[tex]Gain\%=\dfrac{1.6}{6.4}\times 100[/tex]
[tex]Gain\%=\dfrac{1}{4}\times 100[/tex]
[tex]Gain\%=25\%[/tex]
Therefore, the gain percent is 25%.

120 - 20 =
1. Subtract 0 by 0.
0 - 0 = 0
2. Subtract 2 by 2.
2 - 2 = 0
3. Since there isn't a number in the hundred's place, bring the 1 down.

s'ams mother is twice as old as sam in 12 years sam will be as old as his mother was 12 years ago how old are sam and his mother now? sam is?years old his mother is ? years old
Answer:
Sam is 24 years old and his mother is 48 years old.
Step-by-step explanation:
Equations
Let's call
x = Sam's current age
Since Sam's mother is twice as old as Sam:
2x = Sam's mother current age
x + 12 = Sam's age in 12 years
2x - 12 = Sam's mother age 12 years ago
These two last expressions are equal:
x + 12 = 2x - 12
Subtracting x and adding 12:
x = 24
2x = 48
Sam is 24 years old and his mother is 48 years old.
Answer:
Sam is 24 and his mom is 48
