The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less
svp [43]

Answer:

Raul's age is 15 years.

Step-by-step explanation:

r represents Raul's age.

The number of years from the start of the Great Depression to the first presidential election of Richard Nixon is six years less than three times Raul's age.

The first presidential election happened 39 years after the Great Depression and six years less than three times Raul's age is 3r - 6.

Therefore, 3r - 6 = 39

Add 6 to both sides.

3r = 45

Divide both sides by 3.

r = 15

Hence, Raul's age is 15 years.

A mirror should be centered on a wall. The mirror is 36 inches wide and the wall is 18 feet wide. Which equation helps determine
Lera25 [3.4K]

Linear equation is the equation in which the highest power of the unknown variable is always 1.The equation which helps determine the distance x on each side of the mirror is ,

x+3+x=18.

<h3>Given information-</h3>

The length of the mirror is 36 inches.

The length of the wall is 18 feet.

The linear equation has to find out for the distance <em>x.</em>

<em />

<h3>Linear equation-</h3>

Linear equation is the equation in which the highest power of the unknown variable is always 1.

As one feet is equal to the 12 inches. Thus the length l of the mirror in the feet is,

l=\dfrac{36}{12}

l=3

The mirror is 3 feet wide.

The distance on each side of the mirror is <em>x. </em>This distance is equal at both side as the mirror is centered. The distance on each side of the mirror is,

=x+x.

Now the the wall is 18 feet wide which is equal to the distance each side of the mirror and the distance of the mirror. As the mirror is 3 feet wide. Thus the equation which determine the distance x on each side of the mirror can be given as,

x+3+x=18

Hence the equation which helps determine the distance x on each side of the mirror is ,

x+3+x=18.

Circle terms and simplify each of the following expressions.
siniylev [52]

Answer:

a) 2.6  b) -20   c) -44  d) -1494

Step-by-step explanation:

Terms:

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

a) 3+1.4+(-7)

3+1.4-7

Calculate.

-2.6

Terms:  3, 1.4, -7

b) 50+3(-10)+ 2(-20)

Multiply.

50-30-40

Calculate.

-20

Terms: 50, 3, -10, 2, -20

c) 4+(-50)+2

4-50+2

Calculate.

-44

Terms: 4, -50, 2

d) (4+(-170)) (5+4))

(4-170)+(5+4)

Add.

(4-170)x9

Calculate.

-166x9

Multiply.

-1494

Terms: 4, -170, 5, 4

Hope this helps :)
