The algebraic expressions would be a÷9
Answer:
Step-by-step explanation:
In an isosceles triangle, two sides and two angles are equal.
The shortest side of an isosceles triangle is 2x+5 inches. The 2 longest sides are 3 inches longer. This means that the length of each of the longer sides is
2x + 5 + 3 = 2x + 8 inches
The formula for determining the perimeter of a triangle is expressed as
Perimeter = a + b + c
Where a, b and c are the sides of the triangle.
The perimeter of the triangle is 21 inches. Therefore, the equation that can be used to find the length of each side of the triangle is
2x + 5 + 2x + 8 + 2x + 8 = 21
6x + 21 = 21
(6) / (4.5) = 4 / 3 = 1.333...
The level increased by 33-1/3 % .
The old level was 75% of the new level.
The amount of water in the pool also had to
increase 33-1/3 % . If you didn't have that
much water to put in the pool, you couldn't
change the surface level from 4.5ft to 6ft .
Answer:
X=3
Step-by-step explanation:
Subtract 3 from both sides
Simplify 27-3 to 24
Divide both sides by 8
Simplify 24/8 to 3
