Laat month, andy collected 432 stamps, which was 4 times the number of stamps alva collected. If alva collected 6 times as many

Anastasy [175]

After Sally had given 1/9 of her stamps to Andy, she had 280 stamps (since they now have equal shares). So 280 was 8/9 of what she started with, making the 1/9 she handed over equal to 280/8, that’s 35. And Andy was “under” by the same amount she was “over” an equal share, that’s 35 under matching her 35 over, which is 70 altogether.

By all means use algebra but you may find you can reason a word problem through in words.

Find the altitude of an equilateral triangle whose perimeter is 18

Rainbow [258]

Answer:

3√3 units

Step-by-step explanation:

We are asked to find the altitude of the equilateral triangle whose perimeter is 18 . Firstly let us find the side of the∆.

$\rm \implies a + a + a = 18 \\\\\rm\implies 3a = 18 \\\\\rm\implies a = 6$

Now we know that in a equilateral triangle , the altitude of the triangle with side length a is ,

$\rm\implies Altitude =\dfrac{\sqrt3}{2} a$

Plug in the value of a that is 6 , we will get ,

$\rm\implies Altitude =\dfrac{\sqrt 3}{2} a \\\\\rm\implies Altitude =\dfrac{ \sqrt3}{2}\times 6 \\\\\rm\implies Altitude = \sqrt3 \times 3 \\\\\rm\implies\boxed{ \bf Altitude = 3\sqrt3 \ units }$

What is 5s-9<2s+12

IRINA_888 [86]

$5s-9 < 2s+12\ \ \ \ \ |\text{add 9 to both sides}\\\\5s < 2s+21\ \ \ \ |\text{subtract 2s from both sides}\\\\3s < 21\ \ \ \ |\text{divide both sides by 3}\\\\\boxed{x < 7\to s\in(-\infty,\ 7)}$
