-2-3a = -23
pls anwer with steps

Answers

Answer 1

Answer:

Step 1: Simplify both sides of the equation.

−2−3a=−23

−2+−3a=−23

−3a−2=−23

Step 2: Add 2 to both sides.

−3a−2+2=−23+2

−3a=−21

Step 3: Divide both sides by -3.

−3a−3=−21−3

a=7

Answer 2
-3a = -23+2
-3a = -21
a = 7


Place the -2 beside the -23. When you switch sides the negative will change to positive. Then there will be -3a on one side. After you do -23+2 the answer will be -21. -21 divided by -3a will make a = 7

What is 4x + 10 = -26

Answers

Answer:

x = -9

Step-by-step explanation:

I'm assuming you're looking for X.

So first, you'll want to subtract 10 from both sides of the equation.

4x + 10 = -26

    - 10  |  -10

4x = -36

Then from there, you'll want to divide by 4. This allows us to get x by itself.

4x = -36

/4  |   /4

x = -9

The value of 'x' is -9 in the given equation.

To solve the equation 4x + 10 = -26, follow these steps:

Step 1: Isolate the variable term by subtracting 10 from both sides of the equation.

4x + 10 - 10 = -26 - 10

4x = -36

Step 2: Solve for 'x' by dividing both sides of the equation by 4.

4x / 4 = -36 / 4

x = -9

So, the value of 'x' is -9.

If the simple interest on a principal amount of $6000 for 7 years is $2,520, then what is the interest rate as a percent?

Answers

Answer:

6%

Step-by-step explanation:

first multiply $6000 by 7 years then divide 2520 by 42000 to get 0.06

6% because interest= principal amount x rate x time / 100

So 2520=6000xRx7 / 100 = 6%

6(s-9)

Answers

Answer: 6s-54

Step-by-step explanation:

6(s-9) - [simplify]

= (6)(s + -9)

= (6)(s)+(6)(-9)

= 6s-54

The simplified form of the given expression is 6s-54.

The given expression is 6(s-9).

What is Distributive Property?

It is used to solve expressions easily by distributing a number to the numbers given in brackets. That is, a(b+c)=ab+ac

Now, 6(s-9)=6×s-6×9

=6s-54

Hence, the simplified form of the given expression is 6s-54.

If the measure of \angle∠4 is 68 degrees,, find the measure of \angle2∠2 in degrees.

Answers

Hi, there! I'd love to help you out!

We know complementary angles add up to 90 degrees.

Let's say our first angle is x:

x = first angle

It tells us the other angle is 68 degrees more. So we are just adding 68 to our other angle:

x = first angle

x + 68 = second angle

Now add the two and set it equal to 90 degrees:

x + x + 68 = 90

2x + 68 = 90

-68 -68

2x = 22

/2 /2

x = 11 first angle

x + 68 = 11 +68 = 79 degrees second angle

Answer:

1256, 125.6 (this is wrong sorry i didn't know that it wasn't a full circle)

Step-by-step explanation:

A) The area that the sprinkler is spraying is in a circle with a radius of 20 ft. The formula to find the area of a circle is pi*r^2, so the area of this circle will be 400pi (substitute 20 for r). Pi in this problem is 3.14, so 400*3.14 is 1256 feet.

B) The perimeter of the spray is technically just the circumference of the circle. The circumference is 2r*pi, so we substitute 20 for r again and we get 40pi. Again, pi is 3.14 in this problem, so 40*3.14 is 125.6 feet.
