The sum of 2 numbers is 22. three times one number is equal to ten more than the other. find the numbers

qwelly [4]

Translating that problem into an equation with x as a variable we get 3x + x +10 = 22. Combine like terms to get 4x + 10 = 22. Subtract 10 on both sides to get 4x = 12. Divide by 4 on both sides to get x = 3.

Now to plug in. The first number was represented by 3x. So substituting 3 for the x we get 3(3) = 9. And again for the second number represented by x+10, 3+10 = 13.

Your numbers are 9 and 13. To check just add them together. 13 + 9 is 22, I'll save ya the effort.

A scientist crosses two pea plants that are

vivado [14]

The Punnett square is a diagram divided into squares that is used to determine genotypes.

The question is incomplete, as the required details such as the characters that represent the plant heights and the flower colors are not given.

So, I will give a general explanation instead.

Assume the plants that are crossed are represented as: TT and Tt.

The possible genotypes would be TT, TT,Tt and Tt

In the above list of genotypes, genotype T is dominant over genotype t

See attachment for an illustration of the Punnett square.
