David is 4 years older than triple Marie's age. The difference of their ages is 38. How old is David?​
alexira [117]

Answer:

56

Step-by-step explanation:

Let Davids's age = d

Let Marie's age = m

First part of the question tells us: d=4+(3m)

Second part of the question tells us: d=m+38

Sub in 'm+38' for d:

m+38=4+3m

3m-m=38-4

2m=36

m=18

d=m+38

=18+38

=56

Nataliya [291]
Let x = number of $10 coins.
The total number of coins is 44, therefore there are (44-x) $20 coins.
Total value:
10x + 20(44-x) = 620
-10x + 880 = 620
-10x = -260
x = 26   (number of $10 coins)
44-x = 44-26 = 18 (number of $20 cons)
Answer:
26 $10 coins
18 $20 coins

How can the area of this triangle be determined by forming a rectangle? Select from the drop-down menus to correctly complete th
Nuetrik [128]

The area of the triangle can be found by copying the triangle and putting the bases together such that it forms the diagonals of the triangle.

<h3>What is the area of the triangle?</h3>

The area of the triangle is half the product of the height of the triangle and the base of the triangle.

As we know that the area of a rectangle is double the area of a triangle,

therefore, in order to calculate the area of a triangle we need to convert it to a rectangle and then divide the area of the rectangle by 2.

Also, we know that the diagonal of a rectangle divides it into two equal triangles, therefore, we will put the triangle along the diagonal of the base.

Thus, to find the area of the triangle we will copy the triangle and put the base of the together such that it forms the diagonals of the triangle.

Since the triangles are put on each other along the base, therefore, the height(h) of the triangle will be the length of the rectangle, and the breadth of the triangle will be equal to the base of the triangle(b).
