Would 2/5x+6/5=y be a proper answer format(i just want to know if it can be =y)

1 answer:

6 0

yes, it does not matter if the y is at the beginning or at the end. However, most teachers usually prefer to have the y at the beginning as it is easier to read.

Damien has 30 coins, all nickels and dimes. The total value of all these coins is $2.05. How many nickels does he have?

Damm [24]

Hi there!

nickels:19

We know that there is only nickels and dimes in his coin collection..

1.Multiply two terms:

$10$ · $10=1.00$

Then there would be 20 nickels but 1+1=2 not 2.05.

2.Multiply the terms:

$11$ · $10=1.10$

$19$ · $5=0.95$

3.Combine the two terms:

$1.10+0.95=2.05$

Therefore, there would be 19 nickels...

The perpendicular bisectors of AABC intersect at point G. Find the length of BG. B

Paladinen [302]

Answer:

$\overline{GB}$ = 9

Step-by-step explanation:

The given parameters are;

The point of intersection of the perpendicular bisectors of the sides $\overline{BC}$ , $\overline{BA}$ , and $\overline{CA}$ intersect (meet) at point G

Let D represent the point of intersection of the perpendicular bisector from G to $\overline{BC}$ , we have for ΔBGD and ΔCGD;

$\overline{GD}$ ≅ $\overline{GD}$ by reflexive property

∠GDB = ∠GDC = 90° given that $\overline{GD}$ is the perpendicular bisector of $\overline{BC}$

Similarly, $\overline{DB}$ ≅ $\overline{DC}$ , also given that $\overline{GD}$ is the perpendicular bisector of $\overline{BC}$

Therefore;

ΔBGD ≅ ΔCGD by Side-Angle-Side (SAS) rule of congruency

$\overline{GB}$ ≅ $\overline{GC}$ by Congruent Parts of Congruent Triangles are Congruent, (CPCTC)

$\overline{GB}$ = $\overline{GC}$ = 9 by definition of congruency

∴ $\overline{GB}$ = 9.
