Answer: they have

et n = number of nickels

Let d = number of dimes

given:

(1) +n+%2B+d+=+45+

(2) +5n+%2B+10d+=+360+

-------------------

Multiply both sides of (1) by 5

and subtract (1) from (2)

(2) +5n+%2B+10d+=+360+

(1) +-5n+-+5d+=+-225+

+5d+=+135+

+d+=+27+

and, since

(1) +n+%2B+d+=+45+

(1) +n+%2B+27+=+45+

(1) +n+=+45+-+27+

(1) +n+=+18+

She had 18 nickels and 27 dimes

check:

(2) +5%2A18+%2B+10%2A27+=+360+

(2) +90+%2B+270+=+360+

(2) +360+=+360+

Which statement is true?
Ilia_Sergeevich [38]

Answer:

All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.

Step-by-step explanation:

The old math saying: "Every square is a rectangle, but not all rectangles are squares."

What makes a rectangle a rectangle is that it has four right angles.

A square also has four right angles. Therefore, a square is a type of rectangle.

<h3>What makes the other answers wrong:</h3>

A rectangle does not have equal lengths on all four sides like a square does.

A square MUST have four right angles for it to be a square.

SHOE COLLECTION: Marquise, Bron'Tavious, and JayDarius each have a shoe collection of Nike Air Vapor Max shoes. Marquise has two
Natasha_Volkova [10]

Answer:

(a) The number of shoes that Marquise has is 40 pairs of shoes

(b) The number of pairs of shoes that Bron'Tavious has is 20 pairs of shoes

(c) The number of pairs of shoes that JayDarius has is 35 pairs of shoes

Step-by-step explanation:

The given information are;

The number of shoes that Marquise has = 2 × The number of pairs of shoes that Bron'Tavious

The number of pairs of shoes that JayDarius has = The number of pairs of shoes that Bron'Tavious + 15

The total number of pairs of shoes they have all together = 95 pairs of shoes

Let the number of pairs of shoes that Bron'Tavious has = X. Therefore, we have;

The number of shoes that Marquise has = 2 × X

The number of pairs of shoes that JayDarius has = X + 15

The total number of pairs of shoes they have all together = X + X + 15 + 2 × X = 95

X + X + 15 + 2 × X = 95

4 × X + 15 = 95

4 × X = 95 - 15 = 80

X = 80/4 = 20

∴ X = 20

(a) The number of shoes that Marquise has = 2 × X = 2 × 20 = 40

The number of shoes that Marquise has = 40 pairs of shoes

(b) The number of pairs of shoes that Bron'Tavious has = X = 20

The number of pairs of shoes that Bron'Tavious has = 20 pairs of shoes

(c) The number of pairs of shoes that JayDarius has = X + 15 = 20 + 15 = 35

The number of pairs of shoes that JayDarius has = 35 pairs of shoes.
