The present age of the father is twice the age of his daughter. Ten years ago, the
Elenna [48]

Answer:

<h3>           The father is 40 and the daughter is 20.</h3>

Step-by-step explanation:

x           -  the present age of the daughter

2x         -  the present age of the fathter  

x - 10          -  the age of the daughter ten year ago

2x - 10        -  the age of the fathter ten year ago

Father is older than his dauther, so:

2x - 10 = (x - 10) + 20  

2x - 10 = x - 10 + 20  

2x - 10 = x + 10              {subtract x from both sides}

x - 10 = 10                      {add 10 to both sides}

x = 20

2x = 2·20 = 40

statuscvo [17]

Answer+Step-by-step explanation:

m = man's age

s = son's age

m=s+36

(m+8)=3*(s+8)

Resolves to: s=10, m=46

So the man is 46 (=10+36).

In 8 years, son is 18 (=10+8), man is 54 (=3*18 and 46+8), thank you.

Will mark Brainliest! Which of the following is not a condition for a tessellation? The shape or shapes must be repeated. The sh
uysha [10]

Answer:

Option 1 is correct.

Step-by-step explanation:

We have to select the option which is not the condition of a Tessellation.

A tessellation is a regular pattern made up of shapes that perfectly fit together or we can say it is an arrangement of shapes closely fitted together, especially of polygons in repeated pattern with no overlaps and no gaps.

A tessellation use repeated shapes to completely cover a plane with no overlaps or gaps.

Daily life examples of tessellation are honey combs, to man-made objects, like architecture and quilts.

A tessellation can use one or more geometric shapes. Hence, from the given options only the first option is not a condition for tessellation.
