Step-by-step explanation:

If you subtract 60-15 it will give you 45

Hello there!

The right prime factorization is

2*2*2*3*11 because 2 and 3 and 11 are prime.

Take a look at the words "prime" and "factorization"

Can you see something that looks like "prime factors?" Exactly!

2 is prime. 3 is prime. 11 is also prime.

A prime number is only divisible by 1 and itself.

If you remember "Please Excuse My Dear Aunt Sally" that's great as long as you know what that means.

P = Parentheses

E=Exponents

It is true that if BD bisects ∠ABC, then D lies in the interior of ∠ABC

There are three types of triangle and they are

Isosceles triangle in which two sides and two angles are same.

Equilateral triangle in which all the sides and angles are equal.

Scalene triangle in which none of the sides and angles are equal.

According to the given question

If BD bisects ∠ABC, then D lies in the interior of ∠ABC and it is true.

If we draw any line from the vertex B which passes through inside the given triangle then it lies in the interior of [tex]\angle B[/tex].

I see you need help with 14 - 23 evens, so hopefully this is what you need. If not, comment and I will edit it as appropriate :) Have a nice day

14: It is slightly hard to see, but I am going to say 15 mm. We can decide this because the ruler says it is in mm and on both sides are 10 and 20. It is in the middle so we will decide the answer is 15.

16: 3,629 - 429 = 3,198 (not much explanation, just use a calculator or do the subtractation)

18: 491 * 700 = 343,700 (multiply 491 * 7, then add the two zeros onto the end of the answer because it's 700, not 7)

20: 5n = 3,175 ; n = 635 (divide both sides of the equation by 5)

22: See pictured below

After that, 2/3 is equal to 0.66666666666, which we can round to 67%

Even though it is not an even, you said "14 - 23" so here is 23 as well:

230, 240, 250, 260, 270, etc

                       /\

                    256 is inbetween here

It is above 5, so the answer is C 260

$42 for 6floz of juice vs $36 for the same amount. 36 is the better deal!

Answer:

6 fl oz. bottle of orange juice

Step-by-step explanation:

For the  6 fl oz bottle to be equal to the 3fl oz bottle prize, it would need to cost 42, but since it only costs 36$, it would be the better deal.

Answer:

8 seconds if tyres took 1 second each tyre as 2.5/2.5 =1

The question did specify 2 1/2 secs to fll them all up which is 1 second each x 8 = 8 sec total.

Step-by-step explanation:

2  1/2 litres = number of tyres

2 1/2 seconds taken

= if each tyre took 2 1/2 seconds the quetsion should say clear but would be

2 1/2 tyres x 2 1/2 seconds = 6.26 seconds every 2 1/2 tyres

so 8 tyres x 2 1/2 seconds = 20 seconds every 8 tyres

If the 2 1/2 seconds applied to all 2 1/2

then we need to find a multiplier for 1 tyre

Here we divide

2 1/2 / 2  1/2 = 1

8 x 1 = 8 seconds.

Answer:

You have to multiply the input 3 times to get the output.

Answer:

x = 0

y = 1

Step-by-step explanation:

2x + 3y = 3               Multiply this equation by 3

3x + 5y = 5               Multiply this equation by 2

3(2x + 3y = 3)

6x + 9y = 9

2(3x + 5y = 5  )

6x + 10y = 10             Notice the xs are the same.

6x + 9y = 9

6x + 10y =10            Subtract

     - y = - 1                Multiply each side by -1

     y = 1

2x + 3y = 3

2x + 3*1 = 3

2x = 0

x =0

• let's use the quadratic formular to solve the quadratic equation given.

• Considering general quadratic equation; ax² + bx + c = 0

• therefore;

[tex]{ \tt{x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} }} \\ [/tex]

• substitute following the mathematical operation rules:

[tex]{ \rm{x = \frac{ - 2 \pm \sqrt{ {2}^{2} - (4 \times 3 \times - 4) } }{(2 \times 3)} }} \\ \\ { \rm{x = \frac{ - 2 \pm52}{6} }} \\ [/tex]

• split the values:

Answer:

13

Step-by-step explanation:

Use PEMDAS

1. 5-4=1

7-3=4

Now you have the equation: (2x1 + 6x4)/2

2. 2x1=2

6x4=24

Now you have the equation (2+24)/2

3. 2+24= 26

4. 26/2=13

So your answer is 13.

Make sense?

Answer:

13

Step-by-step explanation:

2(5 – 4) = 2

6(7 – 3) = 24

2 + 24 = 26

26 ÷ 2 = 13

Answer:

x = 90

Step-by-step explanation:

- [tex]\frac{8}{9}[/tex] x - [tex]\frac{4}{45}[/tex] x + [tex]\frac{1}{5}[/tex] x = - 70

Multiply through by 45 ( the LCM of 9, 45, 5 ) to clear the fractions

- 40x - 4x + 9x = - 3150 , that is

- 35x = - 3150 ( divide both sides by - 35 )

x = 90
