For the first one, it asks what is half of 12 (obliviously 6), so if that is half of 12, then it would be a quarter of 24( or 1/4)


the second: if 4 is1/5 of 20 (because 20 divided by 5 is 4), then it would equal 2/5 of 10, because if 4 is equivalent to 1/5 of the number 20, then divide that by 2, to get 4=2/5 of 10. (if you are ever unsure about this, resort to decimals. lets say that you don't know if the answer to the second equation is actually 10. then do this: you know that it is asking for 2/5 of_________. turn 2/5 into a percent to equal 40%. now, what number is 4 equivalent to 40%. and if you are still unsure, just divide 40 by 4.) hope this helps

Please help! I am having a hard time trying to solve.
Artyom0805 [142]
HEY THERE!!

GIVEN :- Circle M and K are congruent and line QR is congruent to LN and line OP is congruent to VW.

TO PROVE :- The value of y

SOLUTION:-As we know if two lines are congruent then there equations will be equall.

1. QR is congruent to LN.

=> - x = y+8..........1️⃣

2. OP is congruent to VW.

=> -x = 3y + 16..........2️⃣

Now as we know circle M and K are congruent

so from equation 1️⃣

x= -y-8 put this value in equation 2️⃣

=> y+8= 3y+16

=> 2y = -8

dividing from two to both sides.

=> y= -4

HOPE IT HELPED YOU.

Find the value of x.<br> Round to the nearest tenth.
aev [14]

Answer:

  C ≈ 22.1°

Step-by-step explanation:

The law of cosines formula is given. Solving it for C, we find ...

  C = arccos((a^2 +b^2 -c^2)/(2ab))

where a and b are the sides adjacent to the angle.

Then we have ...

  C = arccos((14^2 +19^2 -8^2)/(2·14·19)) = arccos(493/532)

  C ≈ 22.1°

If you have a fair number of these to do, a spreadsheet is a useful tool. There are also triangle solver apps on the web or your local smart platform that will do this, too.

Select each equation which is equivalent to 60% of 25.
Maksim231197 [3]

The equation which is equivalent to 60% of 25 is x = 0.6 * 25

An equation is used to show the relationship between variables, numbers.

Let x represent the value of 60% of 25. Hence:

x = 60% of 25

x = 0.6 * 25

Hence the equation which is equivalent to 60% of 25 is x = 0.6 * 25

x/25 = 60/100

6/10 = x/25
