Answer:
The answer is below
Step-by-step explanation:
a)
1/4x + 5/2x - 2 = 4 - 1/4x
collecting like terms:
(1/4)x + (5/2)x + (1/4)x = 4 + 2
3x = 6
x = 6/3
x = 2
b)
7.9x + x + 4 = -1.1x - 16
collecting like terms:
7.9x + x + 1.1x = - 16 - 4
10x = -20
x = -2
c)
3.2x + 5.7 = -2.5x
collecting like terms:
3.2x + 2.5x = 5.7
5.7x = 5.7
x = 1
d)
10.1x - 1.6x + 44 = -7
collecting like terms:
10.1x - 1.6x = -7 - 44
8.5x = -51
x = -6
Hence the equations in increasing order of the value of their solutions is:
10.1x - 1.6x + 44 = -7
7.9x + x + 4 = -1.1x - 16
3.2x + 5.7 = -2.5x
1/4x + 5/2x - 2 = 4 - 1/4x
Answer:
530.66
Step-by-step explanation:
The way we find the area of the circle we use the radius of the circle for this one it's 13cm squared * pi or 3.14
For this circle we do 3.14 * 13^2
First we have to square 13: 13^2 = 169
Then we multiply 169 by 3.14: 3.14 * 169 = 530.66
Then we do to the nearest hundredth which is the same as the previous answer: 530.66
I did 14 divided by 0.007 and its 2000 so he can prepare 2000 capsules
Answer:
x = 3
Step-by-step explanation:
x = 4 - 5x + 14
x = 18 - 5x
x + 5x = 18
6x = 18
x = 3

Step-by-step explanation:
A gardener is filling 5 planter boxes (cubical pots) with potting soil. Each box is 1.5 feet long on each side. The
gardener has 3 bags of potting soil, each with a volume of 5 cubic feet.
Is there enough potting soil for the 5 planter boxes?
O There is not enough potting soil. The gardener needs 1.875 cubic feet more potting soil.
O There is enough potting soil. The gardener needs only 3.375 cubic feet of potting soil.
O There is not enough potting soil. The gardener needs 3.75 cubic feet more potting soil.
O There is enough potting soil. The gardener needs only 4.5 cubic feet of potting soil.
O There is not enough potting soil. The gardener needs 7.5 cubic feet more potting soil.
