Step-by-step explanation:

Assumption: 178 wore black (that means some may wear gold + black aka as long as they wore abit of black, it's counted):

since there are 257 students and 34 wore both gold and black, and 178 wore black, the number of students who wore only black = 178 - 34 = 144

no of students who wore only gold = 257 - 144 - 34 = 79

Assumption: 178 students wore ONLY black:

no of students who wore only gold: 257 - 178 - 34 = 45

48.4 - 44    2

4.4 - 4.4      0.2

0            

The division is one of the four fundamental arithmetic operations. The cost of each chicken wing is $2.2.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Peyton bought 22 chicken wings for $48.40. Therefore, the cost of each chicken wing is,

Cost of a single chicken wing = $48.40/22 = $2.2

Hence, the cost of each chicken wing is $2.2.

Answer:

The length of other side of rectangle is 5 units.

Step-by-step explanation:

We are given:

Area of rectangle = 30 square units

Length of one side = 6 units

We need to find the length of other side.

The formula used is: [tex]Area \ of \ rectangle=Length \times Width[/tex]

Considering length = 6, we need to find width.

Putting values in formula and finding length of other side

[tex]Area \ of \ rectangle=Length \times Width\\30=6 \times Width\\Width=\frac{30}{6}\\Width=5 \ units[/tex]

So, Width= 5 units

The length of other side of rectangle is 5 units.

cuz ouya jcajfus fuw f

you didn't say what number you would think of

I'm guessing this is multiple choice but the formatting of the question is a bit hard to understand.

write it algebraically as 2x

2x just means multiply x by 2

The algebraic equation for the other example is 3(x-1) which is 3x - 3

This is not multiplying by two, so it is wrong.

Answer:

The answer is 24.

Step-by-step explanation:

6x(x²-5(1))

6x³=30x

x²÷x=30-60

x=30-6

x= -24

Answer:

-24

Step-by-step explanation:

So first you take f(x) and replace 1 in x so its 1-5 which is -4 you then replace that in g(x) which would be 6*-4 which is 24. Also this isn't college math going this in first year of high school. Imao

Answer:

8 inches

Step-by-step explanation:

Area of a triangle = 1/2 (b) (h)

so let's plug them in.

1/2( (10) (h)

now let's plug in 8

1/2 (10) (8)

10 times 8 equals 80

now

dividing it by 1/2 equals 40

Overall answer: 10 1/9 - 1 5/18x (Most simplified answer)

Step-by-step explanation:

First you have to do all the Distributive property which the answer would be:

2 1/2 - 1/2x + 3 1/9 + 8/9x + 1/6x - 5/18x + 2 14/18 + 1 13/18

Then you have to find the common demoninator which would be 18

After that you have to put them in the correct order since there is two different terms which would be:

2 9/18 + 3 2/18 + 2 14/18 + 1 13/18 - 9/18x + 16/18x + 3/18x - 5/18x

After that you solve the problem which in the end after solving both terms it ends up as..:

10 2/18 - 1 5/18x

and I think that is as simplified as you can go term wise.

I hope this helps and I hope I didn't make a mistake :D
