X = 59, y = 44

2x + 18 + x - 15 = 180
3x + 3 = 180
3x = 177
x = 59

x - 15 = y
59 - 15 = y
44 = y

Design an instructional activity that could help learners recognise that decimal
sp2606 [1]

Fraction refers to a part of a whole; e.g when cup is not completely filled, it covers only a part of the cup

<h3>What is fraction?</h3>

The term fraction refers to a part of a whole. To design an instructional activity that  could help learners recognize that decimal fractions can be applied across environmental situations, we could look at certain things in the house.

For instance, when cup is not completely filled, it contains water that covers only an fraction of the cup. Also, we could boil a part and not a whole cup of rice. These are all examples of fractions.

Tara has a plastic string that is 3 feet long. She will cut the string to make bracelets that are each foot long.
Lady_Fox [76]

Answer:

Mark 3 and subtract 1 from each division

Step-by-step explanation:

Tara will mark the number line at point 3.

Then she will subtract 1 from 3 and mark at point 2.

Again subtracting 1 from 2 the next mark is at 1.

And the last mark is at 0.

The first mark at point 3 shows that the string is 3 feet long.

Now we need 1 foot divisions. So we subtract from 1  division  from point 3  to get 1 foot long string. So we continue to get 3 equal parts each of 1 foot long by dividing the 3 feet long string into 3 equal divisions.

so the first piece is from 0-1 gives 1 foot long string

The 2nd piece is from 1-2 gives 1 foot long string

The 3rd piece is from 2-3 gives 1 foot long string

The three angles of a quadrilateral are 55,73,105 what is the fourth angle
-Dominant- [34]

Answer:

x = 127°

Step-by-step explanation:

Let A, B and C be the three angles of a quadrilateral such that they are 55, 73, 105 respectively.

We know that, the sum of angles of a quadrilateral is equal to 360°. Let fourth angle be x.

55+73+105+x = 360

233+x=360

x = 360-233

x = 127°

So, the fourth angle is equal to 127°.
