Jean, Pierre et Rachel sont des amis. Pierre est 8 ans plus vieux que Rachel, alors que Jean a 15 ans de moins que le double de l’âge de Pierre. De plus, la somme de l’âge de Pierre et du quart de l'âge de Rachel est égal à l'âge de Jean moins 5. Détermine quels sont les âges de chacun.

x=half

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
