<span>(a/20)+(4/15)=(9/15)
a/20 = </span>(9/15)-<span>(4/15)
</span><span>a/20 =5/15
</span><span>a/20 =1/3
a=20/3
</span>
To solve a equation you must first get the variables on the same side of the equal sign. Example: Add -2.5y to both sides so that the variable remains one side only. Now isolate the variable by subtracting 10.5 from both sides. multiply both sides by 10 so that 0.5y becomes 5y, then divide by 5.
Answer:
I believe that it would take 5 hours for 8 people to paint 8 fences.
Step-by-step explanation:
If 2 people are painting 2 fences in 5 hours, then 8 people can also paint 8 fences in the same time because each person is painting one fence. It take 5 hours to paint 1 fence if 1 person is painting it. The same goes for 2 or 8 people painting the same amount of fences as there are people. Im not 100% sure if this is accurate but I hope it helps.
Answer:4.25
Step-by-step explanation:
Answer:
1. >; 2. >
Step-by-step explanation:
1.
⅜ (?) 0.295 Convert ⅜ to a decimal fraction
0.375 (?) 0.295
We can use a <em>number line</em> to decide which number is greater.
In Fig. 1 below, when we go from 0.295 to 0.375, we are moving to the <em>RIGHT</em>, so 0.375 is greater than 0.295.
0.375 > 0.295
2.
-0.770 (?) -4/5 Convert ⅘ to a decimal fraction
-0.770 (?) -0.800
In Fig. 2 below, when we go from -0.80 to -0.77, we are moving to the <em>RIGHT</em>, so -0.770 is greater than -0.800.
-0.770 > -0.800
