Answer:
B.
Step-by-step explanation:
30% of 90 <em>whenever it says "of" put in a multiplication sign </em>
30% x 90 <em> take out the % sign (percent means divided by 100)</em>
30/100 =3/10 <em>simplify,then multiply by 90</em>
3/10 x 90 = 270/10 <em> simplify</em>
270 = 27
90 - 27 = 63 <em>subtract 27 because it is the amount read so far from the total</em>
Keisha has to read 63 more minutes to reach her goal.
I would rewrite the question then show how you got your answer
Answer:
y = 3x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x - y + 12 = 0 ( subtract 3x + 12 from both sides )
- y = - 3x - 12 ( multiply through by - 1 )
y = 3x + 12 ← in slope- intercept form
with slope m = 3
Parallel lines have equal slopes , thus
y = 3x + c ← is the partial equation
To find c substitute (2, 5) into the partial equation
5 = 6 + c ⇒ c = 5 - 6 = - 1
y = 3x - 1 ← equation of parallel line
