7b - 15 = 5b - 3




5c + 16.5 = 13.5 + 10c




20 + 3y = 10 - 2y




17 + 4h + 2 = 1 - 5h

Answers

Answer 1

1. 7b-15=5b-3

move 5b and 15

7b - 5b = -3 + 15

2b=12

b=6

2. 5c + 16.5 = 13.5 + 10c

5c=3

c=3/5

3. 20 + 3y = 10 - 2y

-5y=10

y=-2

4. 17 + 4h + 2 = 1 - 5h

19 + 4h = 1 - 5h

-9h=18

h=-2

Answer 2
1. b=6
2. c=3/5
3. y=-2
4.h=2

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

Explanation:

All I did was Add up the Powers of ten numbers and it was super easy. I hope I helped Good Day Sir!

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.

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
