Answer:

To make it easier, I'm gonna label each angle. Let's say that the angle you already know is angle A.

Angle A: 42

Angle B: 138

Angle C: 42

Angle D: 138

Fatima brought $19.50 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1 3 as much as t

ZanzabumX [31]

Answer:

The brush cost $1.75, the sketchbook cost $5.25 and the paint set cost $10.5

Step-by-step explanation:

Fatima brought $19.50 to the art supply store which she used to buy a brush, a sketchbook, and a paint set.

After buying them, she had $2.00 left over.

Let the cost of the brush be b.

Let the cost of the sketchbook be s.

Let the cost of the paint set be p.

This means that:

b + s + p + 2 = 19.5 __________(1)

The brush was 1/3 as much as the sketchbook:

b = 1/3 * s = s/3 ______ (2)

The sketchbook cost 1/2 the cost of the paint set:

s = 1/2 * p

=> p = 2s________(3)

Putting (2) and (3) in (1):

s/3 + s + 2s + 2 = 19.5

=> 10s/3 = 19.5 - 2

10s/3 = 17.5

10s = 17.5 * 3

10s = 52.5

s = $5.25

Putting this back in (2)

b = 5.25 / 3 = $1.75

Putting the value of a back in (3)

p = 2 * 5.25 = $10.5

Therefore, the brush cost $1.75, the sketchbook cost $5.25 and the paint set cost $10.5

Suppose you had d dollars in your bank account. You spent $12 but have at least $51 left. How much money did you have initially?

PtichkaEL [24]

For this case we must raise an inequality.

We have "d" dollars initially and they are spent 12. Then:

$d-12$

At least 51 dollars remain, then, the sign of inequality is greater or equal in favor of the expression $d-12$ , that is:

$d-12\geq 51$

Resolving:

$d\geq 51 + 12\\d\geq 63$

There are at least 63 dollars left in the account.

Answer:

$d-12\geq 51\\d\geq 63$
