Solve for x. PLEASE HELP ASAP WILL GIVE BRAINLIEST ANSWER

murzikaleks [220]

Answer:

x = 2.6

Step-by-step explanation:

To find x, you need to find how many times you need to multiply 25 to get 65. Using reverse operations will make this easier. 65 / 25 = 2.6. We can check this by multiplying 25 by 2.6, and we get 65.

A triangle has three sides(4x),(2x-6),and(10-x). Using the variable x, write an expression to define the perimeter

bezimeni [28]

Answer:

5x+4

Step-by-step explanation:

well the perimeter is the sum of all sides

so we have

$P=4x+2x-6+10-x\\\\P=(4x+2x-x)+(-6+10)\\\\P=5x+4$

the volume V of a gas at a constant temperature varies inversely with the pressure P. when the volume is 100 cubic inches the pr

fiasKO [112]

Answer:

The pressure is $20\ psi$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

In this problem we have

$V*P=k$

where

V is the volume of a gas at a constant temperature

P is the pressure

we have

For $V=100\ in^{3}$ , $P=25\ psi$

step 1

Find the value of k

substitute the values of V and P

$100*25=k$

$k=2,500$

The equation is equal to $V*P=2,500$

step 2

Find the pressure when the volume is 125 cubic inches

For $V=125\ in^{3}$

substitute in the equation and solve for P

$125*P=2,500$

$P=2,500/125=20\ psi$

If a b and c are three different numbers which of the following equations has infinitely many solutions

Dafna1 [17]

Answer:

c. ax+b=ax+b

Step-by-step explanation:

To know what equation has infinite solutions, you first try to simplify the equations:

$ax=bx+c\\\\(a-b)x=c\\\\x=\frac{c}{a-b}$

In this case you have that a must be different of b, but there is no restriction to the value of c, then c can be equal to a or b.

$ax+b=ax+c\\\\b=c$

Here you obtain that b = c. But the statement of the question says that a, b and c are three different numbers.

$ax+b=ax+b\\\\0=0$

In this case you have that whichever values of a, b and are available solutions of the equation. Furthermore, when you obtain 0=0, there are infinite solutions to the equation.

Then, the answer is:

c. ax+b=ax+b
