Answer:

x=7/8  or x= 0.875

Step-by-step explanation:

Yeah thats about it guys

The value of x is  [tex]\frac{7}{8}[/tex]

Given equation are,

                       [tex]4(5-7x)=6-12x[/tex]

To solve above equation, isolate variable x on one side and constant on other side of equation.

                 [tex]4(5-7x)=6-12x\\\\20-28x=6-12x\\\\-28x+12x=6-20\\\\-16x=-14\\\\x=\frac{14}{16}=\frac{7}{8}[/tex]

Answer:

75.18

Step-by-step explanation:

53.7

x 1.4

-------

2148

5370

-------

7518

but since you moved two decimal places, you put 75.18

Answer: first do 4x7 then 4x3 then 4x5

Next you’ll do that but with the 1. So, 1x7 then 1x3 then 1x5. Then you’ll look at how many numbers are behind the decimal, in the first number there are 2 and In the second there is 1. So three. I got an answer of 7518 after multiplying. I then count three spots starting at 8. My decimal goes in front of the 5. I hope that makes sense to you! If it does, pls mark brainly! Thank you!!

Answer:

12 miles per hour

Step-by-step explanation:

The math formula says that 1 foot per hour is equal to 1/5280 mile per hour.

Lets convert 15 feet per second to per hour.

15 * 60 * 60 =54,000 feet per hour.

Now let's use the equation to convert the feet per hour into miles per hour.

54,000/5,280 = 10.2 mph

12 miles per hour is faster.

Answer:

Step-by-step explanation:Simplifying

0 = 2.5y + -20

Reorder the terms:

0 = -20 + 2.5y

Solving

0 = -20 + 2.5y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2.5y' to each side of the equation.

0 + -2.5y = -20 + 2.5y + -2.5y

Remove the zero:

-2.5y = -20 + 2.5y + -2.5y

Combine like terms: 2.5y + -2.5y = 0.0

-2.5y = -20 + 0.0

-2.5y = -20

Divide each side by '-2.5'.

y = 8

Simplifying

y = 8

SO the answer is y=8 I think srry if i get it wrong

Answer:

d = 40.44

Step-by-step explanation:

Simplifying

25.14 = d + (-15.3)

25.14 = d + -15.3

Reorder the terms:

25.14 = -15.3 + d

Solving

25.14 = -15.3 + d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-1d' to each side of the equation.

25.14 + -1d = -15.3 + d + -1d

Combine like terms: d + -1d = 0

25.14 + -1d = -15.3 + 0

25.14 + -1d = -15.3

Add '-25.14' to each side of the equation.

25.14 + -25.14 + -1d = -15.3 + -25.14

Combine like terms: 25.14 + -25.14 = 0.00

0.00 + -1d = -15.3 + -25.14

-1d = -15.3 + -25.14

Combine like terms: -15.3 + -25.14 = -40.44

-1d = -40.44

Divide each side by '-1'.

d = 40.44

Simplifying

d = 40.44
