Answer 1

Answer:

division!! because 3x is just 3 × x = 15 so to find it you do 15 ÷ 3 which is 5

Answer 2
your answer would be DIVISION. you take 15 and divide it by 3 and you’ll solve what x is, which is 5. :)

Answer:

8w

8w

Yes becuase Noah earned the same amount as Sarah last week.

Step-by-step explanation:

Sarah worked 5 hours+ 3 hours= 8 hours.

Noah only worked 8 hours. So 8=8

then you have to firgure out how much they got paid. But you don’t know how much they get paid, so you represent that with w.
8w = Sarah.

8w = Noah

8w I think tbh I just looked it up tell if it’s right though

What is the effect of multiplying both sides of an inequality by a negative number? Explain and give an example.

Answers

Answer:

It changes the direction of the inequality

Step-by-step explanation:

If a < b, subtract (a + b) from both sides. Then a - (a + b) < b - (a + b), so -b < -a.

only answer if yk how to do this

Answers

Answer:

No

Step-by-step explanation:

Similar triangles must have the exact same angles

All angles must add to a total of 180° so to find x you can do 85°+64°=149° this means that 149°+x°=180° to find that you can do 180°-149° which equals 31°.

Then you do the same for the second triangle

1. 26°+85°=111°

2. 180°-111°=69°

because 69 and 31 aren't the same number these triangles aren't similar

similar triangles must have all the same angle amounts.

No, they aren’t the same shape so that’s a reason for why they aren’t similar.

What is the y intercept of the standard form of the linear equation 2y + 4x = 8

Answers

Step-by-step explanation:

First, let's turn the standard form equation into a slope-intercept form equation.

*(This is an easier method)

Slope-intercept form:

[tex]y = mx + b[/tex]

m = slope

m = slopeb = y-intercept

Switch each term:

[tex]2y = - 4x + 8[/tex]

-4 becomes a negative number since the y and slope have switched.

Divide each number by 2, to simplify y:

[tex]y = - 2x + 4[/tex]

Using the slope-intercept format, we can see 4 is in the position of the y-intercept.

Therefore, the y-intercept is 4.

the y-intercept is 4

Explanation: 2y+4x=8
1. Subtract 4x from both sides, 2y= -4x+8
2. Isolate the y by dividing both sides of the equation by 2, y=-2x+4
3. y-intercept is 4

Sarah factored x2−10x+21
and found the answer to be(x−7)(x−3)
. Is she correct?

Answers

Answer:

(x-3) (x-7)

Step-by-step explanation:

Yes she is correct because

Break the expressions into groups

= (x^2-3x)+(-7x+21)

Factor out x from x^2 - 3: x (x - 3)

Factor out -7 from -7 + 21: -7 (x - 3)

= x(x-3)-7(x-3)

Factor out common terms x - 3

Answer: = (x-3)(x-7)

No the correct answer is -8x+21 to find this you got to use the commutative property to recorder the terms x2-10x+21 so you will want to flip x and 2 so now it will be 2x-10x+21 and then collect like terms 2x-10x+21 so forget about the +21 and - the 2x-10x and you will get -8x and then and back the + 21 and you get -8x + 21 and that’s your answer

Nine boys share 4 pizzas equally. What fraction of a pizza does each boy get?

I have specific answers that I have to choose from but I don't know what order to put 9 and 4 in. What order do I put them in for the equation?

Answers

Answer:

4/9

Step-by-step explanation:

Since the 9 boys share 4 pizzas, which is less than the count of the people eating, it cannot be a number above 1. So this rules out 36 and 9/4. Since 4 is what they are eating, that would be the numerator. So, the number of people is the denominator, so the answer is 4/9.

Answer:

9 boys share pizzas equally. a fraction of this statement does boy get so that. for that pizza I eat 4/9 of pizza therfore 4/9 is the answer

Our constitution does not copy the laws of neighbouring states; we are rather a pattern to others than imitators ourselves. Its administration favours the many instead of the few; this is why it is called a democracy. If we look to the laws, they afford equal justice to all in their private differences; if no social standing, advancement in public life falls to reputation for capacity, class considerations not being allowed to interfere with merit; nor again does poverty bar the way, if a man is able to serve the state, he is not hindered by the obscurity of his condition. The freedom which we enjoy in our government extends also to our ordinary life. There, far from exercising a jealous surveillance over each other, we do not feel called upon to be angry with our neighbour for doing what he likes, or even to indulge in those injurious looks which cannot fail to be offensive, although they inflict no positive penalty. But all this ease in our private relations does not make us lawless as citizens.
