List all the elements of each set. Set of the values of x that turn equation 0.7(x−7)−4.9=5.7 into a true statement

Paraphin [41]

Answer: 22.14 (22.1428571429)

Step-by-step explanation:

Let's Start with the equation

0.7(x−7)−4.9=5.7

Add 4.9 to both sides

0.7(x-7)=10.6

Divide both sides by 0.7

x-7= 15. 1428571429

Add 7 to both sides

x= 22.1428571429 or 22.14

The sum of half of a number and 8 less<br> than the number is 25. Find the number.

LuckyWell [14K]

Answer:

The number is 22

Step-by-step explanation:

let x = the number

$\frac{1}{2} x + x - 8 = 25 \\ \frac{1}{2} x + x - 8 + 8 = 25 + 8 \\ \frac{1}{2} x + x = 33 \\ factor \: out\: x \: on \: the \: left \\ x( \frac{1}{2} + 1) = 33 \\ divide \: both \: sides \: by \: \frac{1}{2} + 1 \\ \frac{x( \frac{1}{2} + 1) }{ \frac{1}{2} + 1} = \frac{33}{ \frac{1}{2} + 1} \\ x = \frac{33}{ \frac{3}{2} } \\ x = \frac{66}{3} \\ x = 22$

Solve the following system of equations and show all your work y=2x^2 y=3x-1

Ann [662]

Answer:

( 1/2 ; 1/2 ) and ( 1 ; 2 )

Step-by-step explanation:

y = 2x².............1

y = 3x-1............2

2x²=3x-1

2x²-3x+1 = 0

(2x-1)(x-1) = 0

x = 1/2 or x = 1

y = 1/2 or y = 2
