The sum of two numbers is 167. The second number is 29 less than three times the first number. Fine the numbers. The two require
Anettt [7]

Answer:

49 and 118

Step-by-step explanation:

Let the two numbers be x and y

x+y = 167

y = 3x-29

Substitute into the first equation

x+ 3x-29 = 167

Combine like terms

4x - 29 = 167

add 29 to each side

4x = 167+29

4x = 196

Divide by 4

4x/4 = 196/4

x = 49

x+y = 167

49+y = 167

y = 167-49

y =118

Find AC for question two
Alex777 [14]

Answer:

AC = 5

Step-by-step explanation:

AC is the diagonal of the rectangle ABCD and splits the rectangle into 2 right triangles.

Using right triangle ABC with hypotenuse AC

Applying Pythagoras' theorem gives

AC² = AB² + BC² ← substitute given values

AC² = 4² + 3² = 16 + 9 = 25

Take the square root of both sides

AC = \sqrt{25} = 5
