Explication étape par étape:
Prendre:
Longueur = x
Largeur = y
Zone du rectangle = Longueur * largeur
Un cinquième de longueur = x / 5
Un tiers de largeur = x / 3
Zone d'origine = xy
Nouvelle dimension:
Longueur = x + x / 5 = (5x + x) / 5 = 6x / 5
Largeur = x + x / 3 = (3y + y) / 3 = 4y / 3
Nouvelle zone = 6x / 5 * 4y / 3
Nouvelle zone = (24/15) xy
Fraction de la nouvelle zone par rapport à la zone d'origine:
(24/15) xy: xy
24/15: 1
24/15
= 8/5
Answer:
C. y=11x
Step-by-step explanation:
y = total amount of money earned
x = hours he works
y = 11x
He earns $11 per hour, so multiplying 11 by x, the number of hours, you are able to find the total amount of money he earns, y.
A. g=4
b. first you're going to subtract 1.4g from both sides;
5.4g + 4 - 1.4g = 1.4g + 20 - 1.4g
then simplify it;
4g+4=20
then, you'll subtract 4 from both sides;
4g + 4 - 4 = 20 - 4
then simplify again;
4g=16
lastly, you will divide 4 from both sides;
4g/4 = 16/4
since 16/4=4, then g=4
