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

For number 24:  I do not know honestly, I am sorry:'(

For number 25 I think that A=true,B=false, and C=false

Step-by-step explanation:

just kidding $72.52

Step-by-step explanation:

A gallon of gasoline costs $2.96.

Your car can travel the distance on each gallon of gasoline = 28.8 miles

Your length of the trip =  miles =

First we calculate the total use of gasoline on the trip.

∵ By 1 gallon gas of gasoline you can cover the distance = 28.8 miles

∴ to take  miles trip gasoline used =

=

=

= 24.5 gallons

Since the cost of one gallon gasoline = $2.96

∴ The cost of 24.5 gallons of gasoline = 24.5 × 2.96

                                                               = $72.52

You spend $72.52 on gasoline for the trip of  miles.

for college, 1-1/2-1/5 = 3/10. Divided by 3 children, 3/10 /3 = 1/10

B. 400 = 1/10 of the total (from above), so 400 = x/10. x = 400*10 = 4000

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.

Step-by-step explanation: there is no mistake.

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.
