solve the diagram below to write an equation and solve for x.
Answer: The equation is (3x) + (2x + 20) + (x+10) = 180, and the x = 25.
Step-by-step explanation:
First, you know that all the measures of angles equal 180°.
So, we can make this equation:
(3x) + (2x + 20) + (x+ 10) = 180
Then, solve for x:
3x + 2x + 20 + x + 10 = 180
Combine the like terms that have the variable, x, in them:
6x + 20 + 10 = 180
Now combine the constant numbers:
6x + 30 = 180
Next, subtract 30 from that side:
6x = 180 - 30
6x = 150
Then, divide:
[tex]\frac{6x}{6}[/tex]= [tex]\frac{150}{6}[/tex]
x = 25
Therefore, the equation is (3x) + (2x + 20) + (x +10) = 180, and the x is 25.
Hope this helps! :)
Answer:
x = 25°
Step-by-step explanation:
Hello!
The sum of angles in a triangle is equal to 180°. If we add all the measures and set it to 180°, we can solve for x.
Solve for x3x + 2x + 20 + x + 10 = 1806x + 30 = 1806x = 150x = 25The value of x is 25°.
Simplify?
2x^2+6x-7x+8-3x^2+1
Answer:
[tex]-x^{2}[/tex]-x+9
Answer & Step-by-step explanation:
[tex]2x^2+6x-7x+8-3x^2+1[/tex]
Combine your like terms.
[tex](2x^2-3x^2)+(6x-7x)+(8+1)[/tex]
[tex]-x^2-x+9[/tex]
So, the simplified form of this equation is -x² - x + 9
write the equation of a line perpendicular to y=3x-2 through the point (-5,8).
Answer:
y=-1/3x +29/3
Step-by-step explanation
We know that the line perpendicular to a slope of 3 is it's opposite reciprocal. So the slope is -1/3. Substitute -5 as X and 8 as Y so you get:
8= -5/3x +b.
B= 29/3
That's your answer.

if 3 kg of flour needs 4 1/2 cups of sugar how much is 4 kg Of flour
Answer:
This is the formula of how to answer this question hopefully it helps :)
Sugar = Flour
A cup of sugar weighs about 7 ounces, and a cup of all-purpose flour weighs about 4-1/2 ounces. So, if we're building a recipe with 1 cup sugar, we'll need about 1-1/2 cups flour (about 6-3/4 ounces).

What is Anti-lock Brakes?An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle.
When driving a car with Anti-lock Brakes (ABS), if your brakes fail when you are trying to stop. You should, Push on your brake pedal and hold it down. Shift to a lower gear and slowly apply your parking brake.

The measure of GI is 80 degrees. What is the measure of
Answer:
∠ GHI = 40°
Step-by-step explanation:
The inscribed angle GHI is half the measure of the intercepted arc GI, thus
∠ GHI = 0.5 × 80° = 40°
The measure of the ∠GHI is 40°.
What is an Inscribed Angle?An inscribed angle is the angle that an arc at any point on the circle subtends.
From the Inscribed angle theorem:
A circle's inscribed angle is half of the central angle that subtends the same arc on the circle, according to the inscribed angle theorem.
That means,
The measure of the ∠GHI
= the measure of the arc GI /2
= 80°/2
The measure of the ∠GHI = 40°
Therefore, the measure of center angle is 40°.

Write an equation of the line in slope intercept form.
Answer:
y=[tex]\frac{-1}{2}[/tex]x+1
Step-by-step explanation:
First, let's do the easiest part, finding the y-intercept, which shows up at the end of your slope intercept equation, y=mx+b, where slope is rise over run!
- Simply look for where the coordinate is on the y-intercept, which is at y = 1!
Then, we need to find our rise over run, which is basically counting from point a to point b. To get to the lower coordinate from the top, we go down two (-2), and over 4. Which means we "rose" -2, and "ran" 4! It's -2 because we went DOWN, and positive 4 because we went FORWARD. This gave us 2 over 4, which is the same as 1 over 2!

6^3 = 216

Answer:
(3/2)^3
Step-by-step explanation:
The trick here is to identify the common base (it is 2) and express all factors except for 3^2 as powers of 2 that can be added or subtracted.
Note that 8 = 2^3, 6 = 2 * 3, 16 = 2^4 and 32 = 2^5. Using this info, we can immediately begin reducing the given expression:
(2^3)(2^3)(3^3) 2^6*3^3 3^3
(8^4)(6^3)(16^-2)÷32 => ----------------------- = ---------------- = --------------
2^4*2^5 2^9 2^3
= (3/2)^3
