Ok I think u have to do subtraction and in a negative way
Answer:
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
Step-by-step explanation:
Let
x -----> number of pages that Polina read
y ----> number of pages that Marcus read
we know that
x+y=108 ----> equation A
x=5y -----> equation B
substitute equation B in equation A and solve for y
Find the value of x
therefore
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
2x+4y=0
3x+y=10
So what we want to do is get y onto one side by itself using whatever equation you like.
So I'm taking 2x+4y=0 and subtracting 4y from both sides
So we end up with
2x=4y
Divide both sides by four
2/4x is 1/2 x
So we get 1/2x=y
Take this and plug it into the other equation
3x+y=10
3x+1/2x=10
Add your like terms
3 1/2x=10
Putting 3 1/2 as a mixed number we get 7/2
So..
7/2x=10
Multiply by the opposite of 7/2 on both sides
Which is 2/7 this will cancel out the left side.
So we end up with
X= 10•2/7
X=20/7
Which is 2 and 6/7 as a mixed number.
Based on this information, William's blood type could be either B or O.
What is Segregation of alleles?
- Allele pairs (several features of the same gene) are segregated during meiosis so that they can be transferred selectively to different gametes.
- During meiosis, maternal and paternal alleles separate.
What is genotype vs phenotype ?
- Genotype: An organism's genetic makeup.
- Phenotype. physical characteristic that arises within an organism as a result of its genotype. Probability law.
- Genotype - the set of alleles that make up an organism.
How does genotype influence phenotype ?
- The alleles you have for a specific gene or collection of genes are referred to as your genotype.
- The physical attribute itself, or phenotype, can be affected by both genotype and environmental variables.
