1.
a) x+5=x+0.25x
b) x+5=x+0.25x
5=0.25x
Multiply both sides by 4
20=x
c)20+5=20+0.25*20
20+5=20+5
25+25
d) Each girl payed 25 dollars and half the bill is 20 dollars.
3.
a)each square = $10
Line up oz and % and cross multiply
If 90oz. Is 100%
23oz is ? %
?=(23•100)/90= 25.55555~25.56% (D)
(-3)(2)(-2)
(-6)(-2)
12
or
(-3)(2)(-2)
(-3)(-4)
12
You get the same answer.
Answer:
y - 3 = 5(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 5 and (a, b) = (- 1, 3), hence
y - 3 = 5(x - (- 1)), that is
y - 3 = 5(x + 1) ← in point- slope form
