Daniela is 23 years older than her daughter. in 5 years, their ages will total 63. how old are they now? i have an exam on this tomorrow ? !

Let daughter present age be x.

Daniela is 23 years older than her daughter.

Daniela present age = x+23

After 5 years daughter age will be x+5 and Daniela age will be x+23+5=28 years.

It is given sum of their ages after 5 years is 63.

Daughter age +Daniela age =63 (after 5 years)

x+5+x+28=63

Adding like terms :

2x+33=63

Subtracting 33 both sides

2x=63-33

2x=30

Dividing both sides by 2

x=15

Daughter present age x= 15

Daniela present age =x+23=15+23= 38 years.

When setting up a proportion to calculate scale drawings, how do you write the proportion? A)actual/actual B)actual/drawing C) drawing/drawing D)drawing/actual

The correct answer is option D: drawing/actual

Suppose there is a drawing that has a scale of 1:10. So, this means anything drawn with the size of "1" would have an actual size of "10" in the real world, so a measurement of 120mm on the drawing would be 1200mm on the actual/real image.
