Step-by-step explanation:

2t^2 + 5t - 63

9x14 = 63

14 - 9 = 5

Step-by-step explanation:

2 t ² + 5t - 63 = 0

2 t² + 14 t. - 9 t -63 = 0

2t ( t + 7) - 9 ( t + 7) = 0

(2t - 9) ( t + 7 ) = 0

9. Jamie ha ahorrado $ 42 del dinero de su asignación para comprar libros. Si compra 5 libros a d dólares por libro, le quedarán 42 5d de su asignación. ¿Cuánto le queda si los libros cuestan $ 3.50 cada uno?

Answers

Answer:

$24.50

Step-by-step explanation:

Jamie has saved $ 42 of his allowance money to buy books. If you buy 5 books at d dollars per book, you will have 42- 5d left of your allowance. How much is left if the books cost $ 3.50 each?

We have the equation

42 - 5d = Amount of Allowance left

d = 3.50

Hence:.42 - 5 × 3.50

= $42 - 17.5

= 24.5

In ΔPQR, r = 4.9 cm, ∠R=21° and ∠P=104°. Find the length of p, to the nearest 10th of a centimeter.

Step-by-step explanation:

The answer is  the length of p, to the nearest 10th of a centimeter is 13.3 cm .

What is the law  of sines ?

he Law of Sines (or Sine Rule) is very useful for solving triangles.

According to the law ,

When we divide side a by the sine of angle A

it is equal to side b divided by the sine of angle B

and also equal to side c divided by the sine of angle C

[tex]\rm \dfrac{a}{sinA} = \dfrac{b}{sinB} = \dfrac{c}{sinC}[/tex]

It is given that in Δ PQR

r = 4.9 cm

angle R = 21

angle P =104

Length of p needs to be found

Therefore by using above equation

[tex]\rm \dfrac{r}{sinR} = \dfrac{p}{sinP}[/tex]

[tex]\rm \dfrac{4.9}{sin21^{0}} = \dfrac{p}{sin104^{0}}[/tex]

p= 13.3 cm

Therefore the length of p, to the nearest 10th of a centimeter is 13.3 cm .

Answers

Answer: yes y=12 is a solution to y over -6

Step-by-step explanation: you simply have to put 12 in for y. 12 divided by -6 = -2.

[tex] \frac{12}{ - 6} = - 2 [/tex]

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

Therefore, y = 12 is the correct solution.

We get -2/1 from 12/-6 by diving the top and bottom by 6.

What is the sum of the greatest and least numbers below:

Answers

Answer:

1/6

Step-by-step explanation:

Step 1: Make remaining mixed numbers improper fractions:

8 1/5 = ((8*5)+1)/5 = 41/5

-8 2/5 = -((8*5)+2)/5 = -42/5

Step 2: Order fractions from least to greatest:

-26/3 <- Least

-42/5

-54/7

41/5

53/6 <- Greatest

Step 3: Find the sum of the least and greatest fractions:

Given: -26/3+53/6

Make equivalent fractions: -52/6+53/6

Rearrange: 53/6-52/6

Evaluate: (53-52)/6 = 1/6

Therefore, the sum of the greatest and least numbers is 1/6
