2.) Three friends earned more than $200 washing cars. They paid their parents $28 for supplies and divided the rest of the money equally. Write an inequality to find possible amounts each person earned?

Answer: the answers are x = -292.5 and y = -122

Step-by-step explanation:

Elimination is combining equations to obtain an equation with just one variable. This is only possible if the coefficients of one variable in both equations are opposed and will cancel each other out when put together. Elimination is most effective when it occurs naturally in the equations, but equations may also be modified to produce typical coefficients by multiplying or dividing equations by a given value. The next step would be to utilize the equation we devised to determine the variable's worth and then insert that value back into the original equation to determine the remaining variable.

For solving the question to find x we have to make the coefficients of y the same. for that, we will multiply the first equation by 2.3 and the second equation by 2.5.

After that, we get the 2 equations as

2.3x-5.75y = 28.75

-2.5x+5.75y = 29.75

then by adding the 2 equations we get

-0.2x = 58.5

and by dividing 58.5 by -0.2 we get

x = -292.5

substituting the value of x in any equations above we get

y = -122

Seven

Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1

so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

Answer:

66 2/3

Step-by-step explanation:

The way to solve this is The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height. Where Ab = area of the polygonal base and h = height of the pyramid. Note: The volume of a pyramid varies slightly depending on the polygonal base.

What i did was i first tried to do 17 x 20 x 10 which game 3400 but when i remembered that V=1/3 x base area x height which would be 1/3 x 17 x 20 = 113 1/3 but if the base was 10 it would be 1/3 x 10 x 20 = 66 2/3. so i think the base is 10 and the answer would be 66 2/3

If i am wrong i'm sorry

[tex]3.5 \times 6 + (5 - 3.5) \times 6 \div 2 = \\ = 21 + 9 \div 2 = \\ = 25.5[/tex]

Answer:

25.5m

Step-by-step explanation:

square area: 6m*3.5m = 21m

Triangle height: 5m - 3.5m = 1.5m

Triangle area: [tex]\frac{1.5m*6m}{2}[/tex] = 4.5m

Total area: 21m + 4.5m = 25.5m

Answer:

Steps:

Pc = 120 - (120/100×20)

Pc = 120 - (1.2×20)

Pc = 120 - 24

Pc = 96

P = Pc + (Pc/100×5)

P = 96 + (96/100×5)

P = 96 + (0.96×5)

P = 96 + 4.8

P = $100.80

Answer:

I’m pretty sure the answer would be $100.80

Step-by-step explanation:

1. Take the $120 and multiply by 0.20, which will give you 24 (that’s 20% of 120)

2. Subtract $120-$24= $96

3. There is a 5% sales tax so take 96 and multiply by 0.05 and you get 4.8

3. Add $96+$4.80= $100.80

Step-by-step explanation:

Answer:

If you used π, 157.079632679 yards or 157.08 yards rounded to the hundredths place. If you used 3.14, the answer is 157 yards.

Step-by-step explanation:

The formula to find the perimeter of a circle is P=2×π×r.

Step 1: Find the radius. In this case, the radius is 25 yards as shown in the diagram.

Step 2: Since the formula only includes multiplication, you can multiply any of the factors. For simplicity, multiply your radius by 2 first. In this case, 2×25=50.

Step 3: Multiply your last number with π. In this case, 50×π=157.079632679 or 157.08 rounded the hundredths place. 50×3.14=157.

Step 4: You found the answer! Hope this helps.

Answer:

about 10 hrs each id say

Step-by-step explanation:

I just did 5 times two

The time taken to fill the pool if it were working alone is 18 hours.

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

The symbols cross (×), asterisk (*), and dot (·) are used to denote multiplication. You most frequently utilize the cross when writing in your notebooks. In computer languages and algebra, the asterisk and dot are both utilized (higher mathematics).

Given:

When 2 pipes fill a pool together, they can finish in 5 hrs,

One of the pipes fills half the pool then the other takes over to finish filling the pool, it will take them 18 hrs

1 / 2 of pool = 9 hrs as given

full pool = 9 × 2 = 18 hours

Therefore, The time taken to fill the pool if it were working alone is 18 hours.

She will have 19 ¹/₂ batches of purple paint

Step-by-step explanation:

r + b = 1 bp

³/₄ r + ³/₄ b = 1 bp

(³/₄ + ³/₄) * 13 = x bp

⁶/₄ = 1 ¹/₂

1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches

VARIABLE KEY:

r = red

b = blue

bp = batches of purple

x = total number of bp

Marcellus's eyes should be 5 cm apart

If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;

Marcellus eyes are 1x far apart as Dan's eyes.

If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.

Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.

Essentially, Marcellus's eyes will be just as wide as Dan's eyes
