The quotient of a number and -7,
decreased by 2, is 10. Find the
number.

-84

Step-by-step explanation:

Let the number be x. Then we have,

(the quotient of a number and -7)

(decreased by 2)

(is 10)

Now we can solve for x,:

So, the original number is -84

-84

Step-by-step explanation:

-2 = 10

add 2 to each side to get:

= 12

multiply each side by -7 to get:

n = -84

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
