Basically find the probability of each one by tacking the number of cards a putting it over the total number of cards and the adding the two mentioned. <span />

One of the same side angles of two parallel lines is 70° greater than the other one. Find the measures of these two angles.

Harman [31]

55° and 125°

same side angles are supplementary

2 supplementary angles sum to 180°

let x be one angle then the other angle is x + 70 ( 70 greater ), hence

x + x + 70 = 180

2x + 70 = 180 ( subtract 70 from both sides )

2x = 110 ( divide both sides by 2 )

x = 55

the two angles are 55° and 55 + 70 = 125°

Use the table shown in the image! 1. Which equation expresses “y” in terms of “x”? A. y=17x B. y=25x C. x=51y D. x=85y 2. What i

levacccp [35]

Answer: 1. A. y=17x

2. $59.50

Step-by-step explanation:

1. In the table , it can be seen that as x increases y increases with the proportionality constant k = $\dfrac{y}{x}=\dfrac{51}{3}=\dfrac{85}{5}=\dfrac{119}{7}=17$ ,.

Equation of direct variation between x and y : $y=kx$

Put k= 17 , we get

$y=17x$ , which is the required equation.

So correct option is "A".

2. To find : The charge for renting a machine for 3.5 hours.

Put x= 3.5 in above equation , we get

$y=17(3.5)=59.5$

Hence, the charge for renting a machine for 3.5 hours is $59.50.

So correct option is "B".

What is 3x-2=-3x+1 plz

MrMuchimi

$\text{Hello there!}\\\\\text{Solve for x:}\\\\3x-2=-3x+1\\\\\text{Add 3 to both sides}\\\\6x-2=1\\\\\text{Add 2 to both sides}\\\\6x=3\\\\\text{Divide both sides by 6}\\\\x=3/6\,\,or\,\,1/2\\\\\boxed{x=1/2}$
