Answer:

B.64

Step-by-step explanation:

75% of a number is 120.

Let's take "x" be the number.

75% of x = 120

75/100 * x = 120

0.75x = 120

x = 120/0.75

x = 160

So the number is 160.

Now we have to find the 40% of the number 160.

= 40/100 * 160

= 0.4 *160

= 64

40% of the number is B.64

Thank you.

write an equation of the line that passes through the given point and has the given slope slope is -3 (-5, 4)

Paraphin [41]

point slope form of a line

y-y1 = m(x-x1)

y-4 = -3(x--5)

y-4 =-3(x+5)

to change to slope intercept form

dstribute

y-4 = -3x-15

add 4 to each side

y = -3x-15+4

y = -3x-11

Serena is building a bookcase she cuts two pieces of wood from one board one piece is 1 7/8 feey long and another is 3.5 ft long

Vladimir79 [104]

Answer:

$\frac{43}{8}$ feet

Step-by-step explanation:

The total change is the sum of the length of two boards she cut.

First board length is 1 7/8th feet. Let's change to improper fraction:

1 7/8 = 15/8 feet

Second board lengrh is 3.5 feet, or 3 1/2 feet. Let's change to improper fraction:

3 1/2 = 7/2 feet

Let's add the two:

$\frac{15}{8}+\frac{7}{2}\\=\frac{15+28}{8}\\=\frac{43}{8}$

The change in original board is 43/8 feet
