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.

2t ² + 5t - 63 Factor the trinomial
Answer:
(2t-9)(t+7)
Step-by-step explanation:
2t^2 + 5t - 63
9x14 = 63
14 - 9 = 5
2t^2+14t - 9t -63
2t ( t+7) -9 (t+7)
(2t-9)(t+7)
Hope this helps!! :))
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
t = - 7 , 9 / 2

Answer:
X=-7
Step-by-step explanation:
Divide then subtract to get x by itself
-30=5(x+1)
Divide each side by 5= -30/5=5(x+1)/5
-30=x+1
-6=x+1
-6-1=x+1-1 Subtract one to get x by itself
-6-1=x+1-1 (cross out both x's.

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

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?
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

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 .
