Iteru [2.4K]3 years ago
8 0

The answer after subtracting the following equation is x= -8/5

Step-by-step explanation:

  • -2x+7y=10 ----- eq(1) , 3x + 7y =2------ eq(2)

  • 7y+3x =2
  • 7y-2x = 10
  • subtracting eq 2 from eq 1 we get
  • 5x = -8
  • x= -8/5

A triangle has angles that measure 46° and 61° what is the measure of the third angle
Brilliant_brown [7]
A triangle in total is 360<span>°. So you add what you are given

46 + 61 = 107

and subtract that from 360

360 - 170 = 190

And the remainder is the last unknown angle.

So, the third angle is 190</span><span>°</span>

18. Brown eyes (B) are dominant to blue eyes (b). The presence of freckles (F) is dominant to the absence of freckles (f). What
MrRissso [65]

Answer:

For bbff we have only 6.3% probability

Step-by-step explanation:

If the parents are heterozygous for both traits, them they are represented by:

BbFf × BbFf

Parent 1: BbFf

Parent 2: BbFf

We have to find the percentage of occurence of bb × ff, which is a child that has blue eyes and no freckles, with no dominant factor.

By distributing the possibilities in a Punnett square, <em>vide</em> picture. We have the following possibilities:

Genotype   Count     Percent  

bBfF  4     25

BBfF  2     12.5

bBFF  2     12.5

bBff          2     12.5

bbfF  2     12.5

BBFF  1     6.3

BBff      1            6.3

bbFF  1     6.3

bbff      1     6.3

For bbff we have only 6.3% probability
