Answer:

Step-by-step explanation:

21/2=12/3

y=10.5≠4

The value of the variable in the given expression is 10.5.

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the variable  in the given expression;

[tex]2 \frac{1}{2} = 1 \frac{2}{3}[/tex] divided by y.

First, we have to convert the mixed fraction into a simple fraction;

[tex]2 \frac{1}{2} = 1 \frac{2}{3}[/tex]

21/2 = 12/3

Then we can write it as;

21/2 = 12/3y

y = 10.5

Hence, the value of the variable in the given expression is 10.5.

Answer:

X = 45

Step-by-step explanation:

Answer:

m∠A = 45 degrees

m∠B = 110 degrees

m∠C= 25 degrees

Step-by-step explanation:

In a triangle, all interior angles add up to 180, which means:

x + x+65 + 25 = 180

2x + 90 = 180

2x = 90

x = 45

m∠A = 45

m∠B = (45+65) = 110

m∠C= 25

Answer:

x = 5

Step-by-step explanation:

To solve for x in 5x - 2 = 3x + 8 start by getting the variables on the same side. To do this, subtract 3x from 5x. (you always do the opposite of the term's operation)

2x - 2 = 8 now add 2 to 8

2x = 10 now divide 2

x = 5

Answer: The constant of proportionality is 8 for the the problem on your left! The constant of proportionality for the one on you right is 6! Hope this helps!

Step-by-step explanation: Vincent earned $24 for 3 hours and so you find out how much he gets paid for 1 hour, then you divide 24 by 3 and get 8! Later he earned $72 for 9 hours, and you do the same thing which is to divide 72 by 9 which also give you 8 and so your unit rate or constant of proportionality is 8. So for the other one Justene can bike for 12 miles in 2 hours and so you find out how many miles she can bike for 1 hours and so you divide 12 by 2 which give you 6 and she can bike 6 miles in 1 hour. Then she biked 36 miles in 6 hours and you divide 36 by 6 which give you 6 and so your constant of proportionality is 6!

Answer:

A and D are functions

Step-by-step explanation:

A is a function because each output is going down the same amount each time, in this case, going down by 4. (the function here is y = -x + 11)

B is not a function because there isn't a constant for y.

C isn't a function either because two x's are 0 with different y values, and you can't have that in a function.

D is also a function because of the equation on the right side.

The red line of the attachment below in A's function graphed, and the lime curve represents D's function graphed.

Answer:

No

Step-by-step explanation:

If you had a triangle with 2 equal acute angles equaling 15 degrees each this would be false, because that would mean that the last angle must be 150 degrees.

C the answer is C because if x=3 then that would make the 2 rectangles equal 6 and if you add 6 to 5 you get 11 which is how many cubes are in the other box

55-7/12=4 have a great day

Step-by-step explanation:

2/3 yard of fabric = 2 feet of this fabric = which is used to make 1 scarf

1 3/4 yards = ?

1 yard = 3 feet = 36 inches

3/4 of 36

36 /4 = 9

9 * 3 = 27

36 + 27 = 63

63 inches of fabric would mean that she can 2 scarves as 2 scarves would use 48 inches or 4 feet as 1 scarf uses 2 feet. She will also have 15 inches of extra fabric.
