Sally is 10 years older than one fifth of her mother’s age. If Sally is 20 years old, how old is her mother?
slamgirl [31]

S = Sally

M = Mother

S = M/5 + 10

20 = M/5 + 10

20 - 10 = M/5

10 = M/5

M = 10 * 5

M = 50

----------------

Her mother is 50 yo

-----------------

50 : 5 + 10 = 20

Which point lies on the line with point-slope equation y - 3 = 4(x + 7)?
mixas84 [53]

Answer:

<h2><em>D. (-7, 3)</em></h2>

Step-by-step explanation:

The standard form of a point slope equation of a line is expressed as shown;

y-y₀ = m(x-x₀) where;

m is the slope of the line

(x₀, y₀) is the coordinate of the point that lies in the line.

Comparing the standard equation given with the equation in question

y - 3 = 4(x + 7) to get the point on the line we will have;

y₀  = 3 and -x₀ = 7

for -x₀ = 7;

multiply both sides with a minus sign

-(-x₀) = -7

x₀ = -7

<em>Hence the coordinate of the point required (x₀, y₀) is (-7, 3).</em>

Rewrite<br> 4/10 : 1/25 as a unit rate.<br><br> A: 10:1<br> B: 25:4<br> C: 2:125<br> D: 100:1
Vladimir79 [104]

Answer:

4/10 : 1/25

4/10 / 1/25 = 4/10 x 25/1 = 100/10 = 10.

10 can also be written as 10:1, so A is correct.

Hope this helps!
