Answer:
89 boys to 71 girls, 89:71, or 89/71
Step-by-step explanation:
x+x+36=320
2x+36=320
2x=284
x=142
This means that there are 142 girls.
142+36=178 boys
Simplify the fraction by dividing both numbers by two.
Answer:
4 weeks
Step-by-step explanation:
Wyatt's equation:
t=14w+40
Julian's equation:
t=19j+20
Since both equations equal the same thing, or <em>t, we can equal them against each other as 1 equation</em>
14t+40=19t+20
(subtract 20 from both sides)
14t+20=19t
(subtract 14t from both sides)
20=5t
(divide both sides by 5)
t=4 weeks
(0, 2 )
to find the y-intercept, let x = 0 in the equation
x = 0 , then 10y = 20 ⇒ y = 2 ← ( y- intercept ) ⇔ (0, 2 )
