7 more than 3 times a number is 52

15

Step-by-step explanation:

Let x be the number

3 times the number  = 3x

7 more than 3 times a number = 3x +7

3x + 7 = 52

3x = 52 -7

3x = 45

x = 45/3

x = 15

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
