Step-by-step explanation:

Given

3 - 10(4p - 1) ← distribute the parenthesis by - 10

= 3 - 40p + 10 ← collect like terms

= - 40p + 13

Answer: the answer is d/f+3

sorry i couldnt find my work for this problem but i hope it helps !

An equation is formed of two equal expressions. When in the given equation the value fo b is d/(f+3).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

fb + 3b = d

Take b as a common term from both the terms on the left side of the equation,

b(f + 3) = d

Divide both the sides of the equation by (f+3),

b(f + 3)/(f+3) = d/(f+3)

Simplify,

b = d/(f+3)

Hence, when in the given equation the value fo b is d/(f+3).

Answer:

It would take him 8 hours

Since every 50 miles takes 1 hour

━━━━━━━☆☆━━━━━━━

▹ Answer

8 Hours

▹ Step-by-Step Explanation

First, find the unit rate:

100 miles ÷ 2 hours = 50 mph

Now, we need to find the time it takes to drive 400 miles so we will divide:

400 miles ÷ 50 mph = 8 hours

If you are looking for total hours, you would add:

2 hours + 8 hours = 10 hours

If you are looking for how long it'll take to drive the 400 miles, it would just remain 8.

Hope this helps!

Answer:

the two numbers are 31 and 32.

Step-by-step explanation:

x+(x+1)=63

2x+1=63

2x=62

x=31

The answers are 31 and 32

The sum of two consecutive numbers is 63. Consecutive numbers are numbers that are in a row (e.g. 1, 2, and 3 are consecutive integers). This means we can represent the two consecutive numbers with x and x+1. Plugging the numbers back into the equation, you get

x + x+1 = 63

Simpifying, you get

2x+1 = 63

Now, you just need to isolate x. To do this, you should subtract 1 from both sides, making the equation.

2x=62

Lastly, you need to divide both sides by 2, making making the equation

x=31

The two integers are x and x+1, and when you plug 31 into that, the numbers are 31 and 32.

Step-by-step explanation:

it is D because you always want x to be a lone fraction and that would be the first step im 99% sure unless someone can correct me :)

Answer:

d) subtract 15 from both sides

Step-by-step explanation:

Process of elimination:

a) 2.5 and x are being multiplied, not subtracted, so (a) is wrong right off the bat.

b) you may divide 2.5 by both sides, but you want to get "x" on one side first. So you would do (b) first either.

c) to get rid of 15, which we need to somehow, we need to do the opposite operation than the one in the equation. 15 is +15, not negative, and so you would need to subtract to get rid of 15. This is why (c) is also wrong.

That leaves us, with (d), because you need to subtract 15 to isolate "x".

Answer:

56 students

Step-by-step explanation:

The equation for your question is 85+2x=197. First you would have to subtract 85, on both sides, leaving you with 2x=112. Then, you'd have to divide by 2 on both sides to isolate the variable. From there, you're left with x=56.

Answer:

Step-by-step explanation:

Given the frequency vibrations for a certain guitar string modeled by the equation

F = 200√T where:

T is amount of tantrums in pounds

If the frequency of the vibrations is 600 vibrations per second, the amount of pounds in tantrums will be gotten by substituting F = 600 into the equation and calculating T as shown:

600 = 200√T

Divide both sides by 200

600/200 = 200√T /200

3 = √T

Square both sides

3² = (√T)²

9 = T

T = 9

Hence 9 pounds of tantrum was used to plug the string

Answer:

28/8=3.50

Step-by-step explanation:3.50 per pear.

Sum of two angles that are supplementary = 180°

Then :-

[tex]3x - 2 + 2x+ 7 = 180[/tex]

[tex]5x + 5 = 180[/tex]

[tex]5x = 180 - 5[/tex]

[tex]5x = 180 - 5[/tex]

[tex]5x = 175[/tex]

[tex]x = \frac{175}{5} [/tex]

[tex]x = 35[/tex]

Which means :-

The measure of the larger angle :-

= 35 × 3 - 2

= 105 - 2

= 103°

The measure of the smaller angle :-

= 2 × 35 + 7

= 70 + 7

Therefore , the value of x = 35 and the measure of the smaller angle = 77° .
