Answer:

7 divided by 2

Step-by-step explanation:

I say 7 divided by 2 because if you round 6 3/4 up one you will get 7 and if you round 1 2/3 up one you get 2 so 7 divided by 2 makes most sense

Answer:

3/8

Step-by-step explanation:

He purchased 3/4 yard of fabric, then used 3/8 of it. You would need to subtract the 3/8 from 3/4 because the fabric is being used up.

Step-by-step explanation:

Commutative property of addition: Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+44, plus, 2, equals, 2, plus, 4.

Answer:

The largest factor that can be pulled out of that expression is 20x, giving you 20x(x² - 2x + 4)

Step-by-step explanation:

20x³ - 40x² + 80x

= 20x(x² - 2x + 4)

Answer:

y=-14x-4

Step-by-step explanation:

Answer:

y + 4 = - 14(x - 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = - 14 and (a, b ) = (3, - 4 ) , then

y - (- 4) = - 14(x - 3) , that is

y + 4 = - 14(x - 3)

Answer:

The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!

The law of sins says: a/SinA = b/SinB = c/sinC

For this to be an isosceles triangle then side a must equal side c

so then a/sinA = c/sinC

Then you can divide both sides by a and raise to the power of -1 and you would get angle A = angle C which makes this isosceles.

Answer:

9 and 7

Step-by-step explanation:

multiply 7 and 1 after that it will 7 and again adding 7 + 2 so it will be 9 so the answer will be 9 and 7

Answer:

Y is the appropriate variable and the most easiest and convenient to eliminate

name 2x + y = 7 as equation i

and 3/2 x - y = 7/2 as equation ii

then add equation i and ii together

(3/2 + 2) x + y - y = (7 + 7/2)

(7/2) x = (21/2)

x = 3

then put in x = 3 in equation i

4 + y = 7

x = 7 - 4

x = 3

Therefore x = 3 and y = 3

Answer:

72 adults

22 children

Step-by-step explanation:

Let c = no. of children

     a = no. of adults

Then 4c = total sales for the children and

         7a = total sales for the adults

So,   a + c = 94      and 7a + 4c = 592  

                                    -4a - 4c = -376

                                      3a = 216

                                        a = 72 adults

        72 + c = 94

                c = 22 children

Step-by-step explanation:

Given

f(x) = x + 5

Let

y = f(x)

y = x + 5

Interchanging the roles of x and y we get

x = y + 5

y = x - 5

f^-1 (x) = x - 5

Answer:

21 for the first one, 144 for the second

Step-by-step explanation:

If you're seeing the same problem I am in class, the rule is: N + 9

N is equal to 12 in this equation

12 + 9 is 21.

So, the answer is 21

If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-

Is 12(12)= 144

Hope this helps!

Answer:

Step-by-step explanation:

hello

15

Step-by-step explanation:

Let us assume p is the number of psychology books and b is the number of biology textbooks.

set up first equation:

we know that the total number of books sold was 393

p+b=393

set up second equation:

we know that there were 79 less biology book sold that psychology so...

p = b + 79

subsitute p in the first equation to solve for b

solve value for p

Answer:

12

Step-by-step explanation:

12×12=144

12 squared equals 144 so square root is 12.

9514 1404 393

Answer:

  12

Step-by-step explanation:

The prime factorization of 144 is ...

  144 = 9·16 = 2·2·2·2·3·3

Grouping pairs of similar factors, we have ...

  144 = (2·2)·(2·2)·(3·3) = (2·2·3)·(2·2·3) = 12·12

  √144 = √(12²) = 12
