Can you explain 3x+4/5=7/10. Solve

Answers

Answer 1
Answer: 3x+ (4)/(5)= (7)/(10)\ \ | -(4)/(5)\n \n3x+ (4)/(5) -(4)/(5)= (7)/(10)-(4)/(5)\n \n3x = (7)/(10)-(8)/(10) \n \n3x = -(1)/(10) \ \ /*(1)/(3)\n \nx=-(1)/(30)



or \n \n (3x+ 4)/(5)= (7)/(10) \ \ /*10 \n \n 2(3x+4)=7\n \n6x+8 = 7\ \ |-8

6x+8-8=7-8\n \n6x=-1\ \ /:6 \n \n x=-(1)/(6)


Answer 2
Answer: 3x+ (4)/(5)= (7)/(10) \n \n3x= (7)/(10)-(4)/(5)\n \n3x=(7)/(10)-(8)/(10)\n \n3x=- (1)/(10) \ /:3\n \nx=-(1)/(10)\cdot (1)/(3)\n \nx=-(1)/(30)

-------------------------------------------------

(3x+4)/(5) = (7)/(10) \n \n10(3x+4)=5\cdot 7\n \n30x+40=35\n \n30x=35-40\n \n30x=-5\ /:30\n \nx=- (5)/(30) \n \nx=-(1)/(6)

(6x - 15) + (x + 8) = 168

Given the function rule f(x) = x^2 - 3x + 2, what is the output of f(-2)

Answers

Answer:

The output value of f(-2) is, 14

Step-by-step explanation:

Given the function:

f(x) = x^2-3x+2             ......[1]

We have to find the output of f(-2).

Substitute x = -2 in [1] we have;

f(-2) = (-2)^2-3(-2)+2

f(-2) = 4+6+2

Simplify:

f(-2) = 12

therefore, the output value of f(-2) is, 12

f(-2) = -2 ^ 2 - 3 * -2 + 2
f(-2) = 4 - (-6) + 2
f(-2) = 10 + 2
f(-2) = 12

If a soccer team played 160 games and won 65% of them, how many games did they win?

Answers

The correct answer is 104 games.

You get that number by dividing 160 with a 100, to find out how large 1% is, and then you multiply it with 65 to find out how much 65% is, and the answer is 104 games.
