Answer:
4 pounds of lime and 5 pounds of pears
Step-by-step explanation:
I + P = 9
0.5l + 1.5P = 9.5
I = 9 - P
0.5(9 - P) + 1.5P = 9.5
4.5-0.5P + 1.5P = 9.5
4.5 + P (1P) = 9.5
P = 9.5-4.5 = 5
I = 9 - 5 = 4
Answer: 4 pounds of lime and 5 pounds of pears
Answer:
Kindly check explanation
Step-by-step explanation:
If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong
3 * 9 = exactly 27
However, for approximation sake ;
We could round 9 to 10 ; and multiply 10 by 3
10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;
3 * 9 = exactly 27 or approximately 30
For every cubic yard, it equals to 27 cubic feet.
So, could have this fraction
![\frac{27 feet^3}{1 yards^3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B27%20feet%5E3%7D%7B1%20yards%5E3%7D%20)
And we want to convert 3 cubic yards into cubic feet.
We can express 3 cubic yards as
![\frac{3 yards^3}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%20yards%5E3%7D%7B1%7D%20)
Now multiply the
![\frac{3 yards^3}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%20yards%5E3%7D%7B1%7D%20)
fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.
![\frac{3 yards^3}{1} * \frac{27 feet^3}{1 yards^2} = \frac{81 feet^3}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%20yards%5E3%7D%7B1%7D%20%2A%20%5Cfrac%7B27%20feet%5E3%7D%7B1%20yards%5E2%7D%20%3D%20%20%5Cfrac%7B81%20feet%5E3%7D%7B1%7D%20)
So, 3 cubic yards to equal to 81 cubic feet.
Answer:
Step-by-step explanation:
x2+y2+ax+by+c=0
Step 1: Add -by to both sides.
ax+by+x2+y2+c+−by=0+−by
ax+x2+y2+c=−by
Step 2: Add -x^2 to both sides.
ax+x2+y2+c+−x2=−by+−x2
ax+y2+c=−bax+y2+c+−y2=−by−x2+−y2
ax+c=−by−x2−y2
Step 4: Add -c to both sides.
ax+c+−c=−by−x2−y2+−c
ax=−by−x2−y2−c
Step 5: Divide both sides by x.
ax
x
=
−by−x2−y2−c
x
a=
−by−x2−y2−c
