(3x + 2) to the power of 2(i didnt know how to put that on keybored)

Answer:

The value of x is 60°, and the value of y is 50°.

Step-by-step explanation:

50°+70°+x°=180°

x=180°-120°

x=60°

similarly the angle on the left side of x will be

70°

All these angles form 180°(linear pair)

hence, 70°+60°+y°=180°

130°+y°=180°

y°=180° - 130°

y°=50°

Answer:

4 23/42 ≅ 4.547619

Step-by-step explanation:

The second part of the trip took 1.5 hours.

Average Speed is the ratio of the total distance travelled to the total time taken to cover that distance. It is given by:

Average Speed = total distance ÷ total time

Given that the distance from the house to the tournament is 210 miles, hence:

Total distance = 210 miles

Also, The journey was in two parts, the first part took 2 hours. Let the second part take t hours. Therefore:

Total time = t + 2

The average speed of 60 miles per hour, hence:

60 = 210 ÷ (t + 2)

60(t + 2) = 210

60t + 120 = 210

60t = 90

t = 1.5 hours

Therefore the second part of the trip took 1.5 hours.

Answer:

13

Step-by-step explanation:

So the concept is that co-interior angles add up to 180 in parallel line. This means:

3x + 9 + 9x + 15 = 180

So we solve for x.

12x + 24 = 180 ( What I did was simplifying the equation).

12x + 24 - 24 = 180 - 24

12x / 12= 156 / 12

x = 13

Answer:

1.2

Step-by-step explanation:

1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: [tex]\frac{0.8}{100} * 150 = x[/tex]

2. Now, let's solve for x!

Therefore, 0.8% of 150 is 1.2!

Answer:

Step-by-step explanation:

27^x = 9÷(3^x)

So (3^3)^x = (3^2)÷(3^x)

So 3^3x = 3^(2-x)

Comparing powers on both sides,

3x = 2 - x

So, 4x = 2

So, x = 1/2

Given ( 27 ) ^ x = 9 / 3 ^x

⇒ ( 3 × 3 × 3 )^x = ( 3 × 3 ) / 3^x

⇒ ( 3 ³ )^x = 3² / 3^x

⇒  3 ^ 3x × 3^x = 3²            [ since  ( a ^m)^n = a ^mn ]

⇒ 3^ (3x +x) = 3²                [ since a^m × a^n = a ^m+n ]

⇒ 3^4x = 3²

⇒4x = 2                      [ since  If a ^m = a ^n then m = n ]

⇒ x = 2 / 4

 ∴ x = 1 / 2

TO MUCH STEPS

Answer:

42

Step-by-step explanation:

times 70 by two to get how many notebooks needed total.

70*2=140

subtract how many notebooks you already had.

140-98=42

The no. of notebooks we need more will be equal to 42 notebooks.

It is given that no. of notebooks available is 98 and there are 70 children in class.

We have to find no. of notebooks needed more if each child gets two notebooks.

What is algebra ?

Algebra is the branch of mathematics that deals with various symbols and the arithmetic operations and the symbols are called variables.

As per the question ;

No. of notebooks we had in class = 98 notebooks

And

Total no. of children = 70 children

The no. of notebook each child gets = 2 per child

So ;

70 children will get no. of notebooks ;

= 70 × 2

= 140 notebooks

The no. of notebooks we need will be ;

= 140 - 98

= 42 notebooks

Thus , the no. of notebooks we need will be equal to 42 notebooks.
