The first option is the correct answer
Explanation
Multiply the 3 pound bag value by 3 giving you 18.12 which is less than the 9 pound bag
X=18
Explanation:
The sum of the 3 angles in a triangle is 180∘
hence , the sum of the 3 angles given must equal 180
We can form an equation
2x + 3x + 5x = 180 ⇒10x=180⇒x=180/10
x=18
2(x) = 2(18)=36
3(18)=54
5(18)=90
Speed is measured in miles per hour (mph).
<span>The formula Distance equals rate times time (d=rt) can be rearranged and the rate can be solved, </span>
<span>d = r*t => r = d / t . d = 100 miles, time = 6 hours, Rate = 16.66 mph (16 and two thirds). </span>
<span>The same formula can be used for the second part, </span>
<span>21000 / 24 = rate, Rate = 875 kilometers per hour</span>
Answer:
pen = 12
book = 24
Step-by-step explanation:
x = cost of pen
2x + x = 36
3x = 36
x = 12
pen = 12
book = 24
Answer:
10/12 = 5/6
10/12 = 20/24
10/12 = (10*x)/(12*x) with x ≠ 0
