The temperature at 6: 00 a. m. was –12°f. by 3: 00 p. m. the temperature had risen 21°f.
what was the temperature at 3: 00 p. m.?
a.
–33°f
b.
–9°f
c.
9°f
d.
33°f

if you was gonna solve for a, a is a   < -12

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
