Answer:
ok i am here to explain :)
Step-by-step explanation:
So, for #6, all we do is -8+6, since it said sum, so we add, and we get -2. this is 2 more than -4, and to check, all we would have to do is -4+2, which equals -2.
for #7, all we have to do is -8+(-6), since again it says sum so we add. the sum of these values are -14. for the second part, because it says "product" this means we multiply! and when we multiply -2 by 4, we get -8. this would lead us to believe that the sum is 4 less than. we can check it by subtracting positive 4 from the negative 8, or -8-4, which would give us -12.
for #11, all i really did was plug it into a calculator, and for the first one, i got 4, and for the second one i got -4. this would give us a difference of 8, and to check all we would have to do is add the 8 to the negative 4, or -4+8=4.
Hope this helps, please mark as brainlest.
Answer:
6: -2
7: 14
11: -4
Step-by-step explanation:
6:
-8 + 6 = -2
-2 is bigger than -4 because it is closer to 0. If it was regular numbers, like 2 and 4, 4 would be larger! :)
7:
-8 - 4 = -12
4 - 2 = 2
The correct answer is 14 because there are 14 numbers between 4 and -12 :)
11:
(–3 + 5)^2
2^2
4
–(–3 + 5)^2
-2^2
-4
The correct answer is 4 because it is a positive number and positive numbers are ALWAYS bigger than negative numbers :)

Explanation:
We first let 0.83 (3 being repeated) be x.
Since,
x is recurring in 1 decimal places, we multiply it by 10.
10x=8.33
Next, we subtract them.
10x−x=8.33−0.83
9x=7.5
Lastly, we divide both sides by 9 to get x

boys = 3/4 x = .75x
girls = x
x + .75x = 35
1.75x = 35
x = 35/1.75
x = 20
girls = 20
boys = 3/4 * 20 = 15

What is Algebra?Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
There are ten pieces of pizza.
Anthony ate 1/8 of the pizza for dinner.
Then the amount of pizza left will be
⇒ 1 – 1/8
⇒ (8 – 1) / 8
⇒ 7/8
He ate 3/10 for a bedtime snack.
Then the amount of the pizza will be
⇒ 7/8 – 1/10
⇒ 31/40
The pizza has he eaten in all.
Then the amount of the pizza he ate will be
⇒ 1 – 31/40
⇒ 9 / 40
Then the amount of the pizza he ate will be 9 / 40.

You could glaze bowls and plates. The bowls use pints of glaze and the plates use pints of glaze, for a total of 6 pints of glaze.
Answer:
a.
How many bowls could you glaze?
we can only glaze 6 bowls
How many plates could you 10 plates
b. You want to glaze 5 bowls, and then use the rest for plates.
How many plates can you glaze?
Hence we can only glaze 2 plates
How much glaze will be left over?
8/9
c. How many of each object could you glaze so that there is no glaze left over?
= 4 4/23 bowls and 4 4/23 plates
Step-by-step explanation:
You have 6 pints of glaze. It takes 7/8 of a pint to glaze a bowl and 9/16 of a pint to glaze a plate.
a.
How many bowls could you glaze?
It takes 7/8 of a pint to glaze a bowl
We have 6 pint
7/8 pint = 1 bowl
6 pints =
6 pints/ 7/8
= 6 × 8/7
= 48/7
= 6.8571428571 bowls
We can't glaze decimal of a bowl, hence, we can only glaze 6 bowls
How many plates could you glaze?9/16 of a pint to glaze a plate.
9/16 pint = 1 bowl
6 pints =
6 pints/ 9/16
= 6 × 16/9
= 10.666666667 plates
We can't glaze decimal of a plate, hence, hence can only glaze 10 plates
b. You want to glaze 5 bowls, and then use the rest for plates.
1 bowl = 7/8 pints
5 bowls =
5 × 7/8pints
= 4 3/8 pints of glaze would be used for bowls
How many plates can you glaze?
The rest is for plates, hence:
6 pints - 4 3/8
1 5/8 pints of glaze would be left over to glaze plates.
Hence if
9/16 pints = 1 plate
1 5/8 pints =
= 2 8/9
Hence we can only glaze 2 plates
How much glaze will be left over?
8/9
You could glaze plates and will have pints of glaze left over.
c. How many of each object could you glaze so that there is no glaze left over?
We have 6 pints of glaze
7/8 x + 9/16 × x = 6 pints
= 4 4/23 bowls and 4 4/23 plates
