Answer:
x= 144
Step-by-step explanation:
the answer written above is 100% WRONG, i looked it up on google and it gave me a straight up answer.
Multiply the second equation by -3 in order to cancel out U
3u+z=15
-3(u+2z)=10
3u+z=15
-3u-6z=-30. Then u subtract those two equations
-5z=-15
Z=3
To solve for u, plug in the z in one of the equation (doesn’t matter which one)
3u+3=15
3u=12
U=4
Ur answer is
U=4. Z=3

Answer:
6.784 × 10¹⁰
Step-by-step explanation:
→ First count the number of 0's
0000000 = 7 zero's
→ Count how many decimal places until a single digit
6.784 = 3 decimal places
→ Add the number of zero's with the decimal place's
7 + 3 = 10
6.784 × 10¹⁰
47 X 4 = 188. That is 50 too many legs. 50/2=25. If you take away 25 sheep and add 25 chicken you have the correct number of legs. There are 25 chicken and 22 sheep.
