Answer:

x = 20

Step-by-step explanation:

The 3 angles lie on a straight line and sum to 180° , that is

3x + 80 + 2x = 180

5x + 80 = 180 ( subtract 80 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20

Answer:

Here,3x°+80°+2x=180° [Angles on a line]

or,3x°+2x°+80°=180°

or,5x°+80°=180°

or,5x°=180°-80°

or,5x°=100°

or,x°=100/5

Therefore,x°=20°

1+4=5 2+5=12 3+6=21 8+11=? puzzle answer
Over [174]
<span>The answer is 97. The first expression is 1+4=5. In the next expression, both numbers are increased by 1 while their sum is increased by 7: (1+1)+(4+1) = (5+7). 2+5=12. In the next expression, both numbers are increased by 1 again, but the sum is increased by the next odd number (which is 9): (2+1)+(5+1)=(12+9). 3+6=21. So, the series will look like this: 1+4=5. 2+5=12. 3+6=21.4+7=33. 5+8=46. 6+9=61. 7+10=78- 8+11=97.</span>

Step 1: Distribute -2 to 5x and 8. Step 2: 6x. Step 3: 16. Step 4: -16.
Ronch [10]

The simplified form of the expression is -10x - 16

<h3>Factorizing expressions</h3>

Given the expression -2(5x + 8)

In order to factorize the expression, we will use the distributive property. Distribute -2 over 5x and 8 to have:

Step 1: Distribute -2 to 5x and 8

-2(5x + 8) =-2(5x) -2(8)

Simplify

-2(5x + 8) = -10x - 16

Hence the simplified form of the expression is -10x - 16

I need help with #46!!!!
Gre4nikov [31]

Remark

There are two formulas for doing this. I'll use the one that does not involve the slope. I think it will be easier for you to understand.


Step One

Decide which point is (x1,y1)

Since point P is 2/5 the way up from point A, we will call (x1,y1) point A


Step Two

Write the givens.

Point(A) = (-2,-3)

Point(B) = (3,2)


Step Three

Write the formula

x1 + ratio*(x2 - x1), y1 + ratio(y2 - y1)


Sub and solve.

-2 + 2/5 *(3 - - 2) , -3 + 2/5*(2 - -3)

-2 + 2/5(5) , - 3 + 2

-2 + 2 , - 1

P = (0 , - 1) <<<<<< Answer


If this turns out to be incorrect please notify me.
