Answer:
second option, (u - 12 - 3b)/4
Step-by-step explanation:
isolate the "a" by bring each term to the other side, and finally div by 4
u = 12 + 4a + 3b
u - 12 = 4a + 3b
u - 12 - 3b = 4a
(u - 12 - 3b)/4 = a
Area is l*w. To find the width, do 144/24 to get a length of 6m.
Answer:
3. 1/28
4. About 7.11%
Step-by-step explanation:
3.
Since two of the eight ads are by a local retailer, the probability of picking either one once is 2/8=1/4. However, the second time, since on of the ads has already been used and there are a total of 7 left, the new probability is 1/7. Multiplying these two together, you get 1/4*1/7=1/28.
4.
To find the probability, you need to find the area of the smaller triangle and the rest. The formula for the area of an equilateral triangle is , meaning that the area of the big triangle is and the area of the little triangle is . . Hope this helps!
