Answer:
x= -2
Step-by-step explanation:
Let's solve your equation step-by-step.
15−10x=5(x+9)
Step 1: Simplify both sides of the equation.
15−10x=5(x+9)
15+−10x=(5)(x)+(5)(9)(Distribute)
15+−10x=5x+45
−10x+15=5x+45
Step 2: Subtract 5x from both sides.
−10x+15−5x=5x+45−5x
−15x+15=45
Step 3: Subtract 15 from both sides.
−15x+15−15=45−15
−15x=30
Step 4: Divide both sides by -15.
−15x/-15 = 30/ -15
x= −2
How come two negatives make a positive, but three negatives makes a negative? Does this have to do with there being an odd/even amounts of negatives and cancelling each other out?
Okay well work step by step. If there is three negatives, you first want to multiply the first two negatives. Your number will come out positive but you are still left with one more negative. so you will multiply the positive number with the negative number which comes out with a negative number.

everyday finn brushes his teeth 3 times , for 2 min each time , he flosses twice a day , for 5 minutes each time. In a year , how much time does finn spend brushing and flossing his teeth?
Answer:
5,840 minutes
Step-by-step explanation:
Assuming there are 365 days in a year. If finn brushes his teeth 3 times , for 2 min each time then the time spent to brush his teeth in a day
=3 * 2 minutes
= 6 minutes
If he flosses twice a day , for 5 minutes each time, then the time spent in a day to floss
= 2 * 5 minutes
= 10 minutes
Hence total time spent in a day brushing and flossing
= 6 + 10
= 16 minutes
Hence the time spent in a year brushing and flossing
= 16 * 365
= 5,840 minutes

Answer:
The slope of the line = m = 3
Step-by-step explanation:
Given the table
x 3 6 8 12
y 7 16 22 34
Taking any two points let say (3, 7) and (6, 16)
(x₁, y₁) = (3, 7) (x₂, y₂) = (6, 16)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [16 - 7] / [6 - 3]
= 9 / 3
= 3
Therefore, the slope of the line = m = 3

Answer:
m∠J = 85°
Step-by-step explanation:
Angles G and H are congruent to angles Q and R, respectively. The sum of angles in a quadrilateral is 360°, so we have ...
∠J +∠F +∠G +∠H = 360°
∠J +109° +122° +44° = 360°
∠J = 360° -275°
m∠J = 85°

The formula for the gravitational potential energy of an object is U = mgh, where U represents the potential energy, m represents the mass of the object, g represents the acceleration due to gravity, and h represents the object’s height above the ground. Solve this formula for h.
U=mgh
U/m=gh
U/mg=h
therefore:
h=U/mg
The solution for h is h = U / (mg),
where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.
Here, we have,
To solve the formula U = mgh for h (the height above the ground),
we need to isolate h on one side of the equation.
Here are the steps:
Start by dividing both sides of the equation by mg:
U / (mg) = (mgh) / (mg)
This simplifies to:
U / (mg) = h
Now we have isolated h on one side of the equation.
Therefore, the formula for h is:
h = U / (mg)
So, the solution for h is h = U / (mg),
where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.
