Answer:
152 Chairs
Explanation:
7 rows of 23 chairs: 7 · 23
7 · 23 = 161
Remove 9
161 - 9 = 152
Answer:
14 AND 22
Step-by-step explanation:
LET THE LARGER NUMBER BE X AND SMALLER BE Y
X + Y = 36 …….1
2X – Y = 6…… 2
WE SOLVE SIMULTANOUSLY
ADDING EQATION 2 AND 1
2X + X + Y + (-Y) = 36 + 6
3X + Y – Y = 42
3X = 42
DIVIDING EACH TERM BY 3
3X/3 = 42/3
X = 14
THEN PUTTING X = 14 IN EQUATION 1
14 + Y = 36
Y = 36 – 14
Y = 22
In the figure we have three right angles .The triangles similar to each other .Similar triangles have sides in proportion .The altitude rule is true for the triangles .
The theorem states :The altitude to the hypotenuse of a right triangle is the mean proportional between the segments into which it divides the hypotenuse.

Substituting the values from the triangles we ahve:

s is the right answer
