Answer:

I don't see question 18?

Step-by-step explanation:

For number 22:  0.2(x+50)-6=0.4(3x+20)

                            0.2x +10-6=1.2x+8

                           -0.2x          -0.2x

 -----------------------------------------------------------

                                     10-6=1x+8

                                       +6       +6

----------------------------------------------------------------

                                         10=7+8

                                         -7  -7

----------------------------------------------------------------

                                           3=8

Answer:

I think C? i.d.k

Answer:

Its 93

length of Jim's backyard , L = 15 5/6 = 95/6 yards

width of Jim's backyard , B = 10 2/5 = 52/5 yards

so, area of rectangular backyard = L × B

= 95/6 × 52/5

= (95 × 52)/30

= 494/3 yard²

Jim buys sod of length 1 1/3 = 4/3 yards and width = 1 1/3 yards = 4/3 yards .

so, area of rectangular sod = length × width

= 4/3 × 4/3 = 16/9 yard²

number of sod = area of backyard or area of sod

= (494/3)/(16/9)

= 494 × 3/16

= 92.625 ≈ 93

therefor, 93 pieces of sod will Jim need to buy to cover his backyard.

Answer:

A

Step-by-step explanation:

Answer:

C. 270°

Step-by-step explanation:

The transformation I saw was 90° clockwise but the question stated counterclockwise so that answer is C.

90° clockwise is same as 270° counterclockwise.

the angle of rotation is, C. 270°.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

Sorry if it is incorrect! :(

Answer:

= -0.75-0.4

= -1.15

Step By Step

The simplified result of -0.75 - 0.4 is -1.15.

To simplify the expression -0.75 - 0.4

Step 1: Start by subtracting the decimals without considering the signs: 0.75 - 0.4 = 0.35.

Step 2: Now, remember that the original expression had a negative sign in front of it, so the final answer needs to be negative. Since we already calculated a positive value (0.35), we'll make it negative by adding the negative sign: -0.35.

Step 3: Finally, we need to subtract the whole number parts. -0 (whole number part of -0.75) - 0 (whole number part of -0.35) = 0.

Putting it all together, we have -0 - 0.35 = -0.35.

But remember, the original expression had a negative sign, so the final result is -(-0.35), which simplifies to -0.35.

In mathematical terms, -0.75 - 0.4 = -0 - (0.75 - 0.4) = -0 - 0.35 = -0.35.

So, the simplified answer is -0.35, which can also be written as -1.15 (since -0.35 = -1.00 + 0.15).

In summary, when you subtract -0.4 from -0.75, you get -0.35 or -1.15, depending on how you choose to express it.

Answer:

x=20

Step-by-step explanation:

So we have [tex]\frac{x}{24} =\frac{30}{36}[/tex]

divide 30/36 to get

[tex]\frac{x}{24} =.833[/tex]

then multiply that by 24

[tex]x=.833*24[/tex]

which will get you

[tex]x=20[/tex]

The value of x from the given proportion is 20.

The given proportion is x/24 = 30/36.

Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Here, x/24 = 5/6

x/4 = 5/1

x=20

Therefore, the value of x from the given proportion is 20.
