Answer: 2t + 18
Step-by-step explanation:
A) 8.9
Triangle is half of a square, so a square has double the area of the triangle.
40 x 2 = 80
Area is the square root of 80.
Square root of 80 = about 8.9
x = 8.9
Answer:
60 ml of 40% saline and 90 ml of 15% saline
Step-by-step explanation:
We can call the amount of 40% solution x and the amount of 15% solution y.
x + y = 150 -- (1)
0.40x + 0.15y = 150 * 0.25 -- (2) --- 150 * 0.25 = 37.5
40x + 15y = 3750 (Multiply (2) by 100 to get rid of decimals)
15x + 15y = 2250 -- (3) (Multiply (1) by 15)
25x = 1500 (Subtract (3) from (1)
x = 60
y = 150 - 60 = 90
Answer:
<u><em>9 (3x+2)</em></u>
Step-by-step explanation:
<u>27x + 18 = 9 (3x+2)</u>
<em>By simplifying the Given expression you get 9 (3x+2) </em>
<em>and no matter how many times you simplify that expression you always get the expression you started with so in other word their equavalent to each other</em>
<em />
<u><em>Hope this helps</em></u>
