5 x 2/4 = 5/1 x 2/4 = 2 2/4 = 2 1/2
<span>8) </span> not equal, not equal, equal
9) 1/8 of a pound is in each portion
10) $3.75
I hope this helps you. With number 8, all i did was simplify the fractions and see if the can be equal to the first fraction in the whole question and determined my answer by that. For number 9, i divided 1/2 of a pound by 2 and got 1/4 of a pound, and then divided that by 2, and i got the answer of 1/8 of a pound. When it come to number 10, i multiplied $0.50 by 7 and got $3.50, and since the last part was half a foot i knew it would cost $0.25 instead of $0.50, so i just added that to the answer and got the end result of $3.75.
Answer:
90°
Step-by-step explanation:
5x+20=9x
20=9x-5x
20=4x
x=5
5x+20+9x=
5(5)+20+9(5)=
25+20+45=
90
Answer:
1. 100=x^2+y^2 Look at the picture
2. 0=3x+4y Look at the picture
Step-by-step explanation: Hope this help :D
Equation is: 200x + 250y = 3800
Put x = 0
then 250y = 3800
y = 3800 / 250
y = 15.2
Now, Put y = 0
200x = 3800
x = 3800/200
x = 19
So, the coordinates are: (19, 0) & (0, 15.2)
We will mark those coordinates & draw the line from origin. Graph is done
Hope this helps!
You don't just go removing numbers here and there without a good reason. In any case, your whole approach here is wrong. You're calculating 60 percent of 12. But the question says to take 12 out of a group of 60 and tell what percent of the group you have. That's (12/60) x 100.
