Answer:

-6x and 5x are like terms.

-9 is a constant.

-2y is a term

Answer:

a. Convert to improper fraction first:

-2⁴/₉ = -24/9

= -24/9 * 1/2 = -24/18 = -4/3

= -1¹/₃

b. -2/3 * 1/4 = -2/12

= -1/6

c. Convert to improper fraction:

= -1¹/₂ = -3/2

= -3/2 * -1/6

= 3/12

= 1/4

d. Convert to improper fraction:

= 2¹/₃ = 7/3

= 1/6 * 7/3

= 7/18

Answer:

Answer:

161 boys

Step-by-step explanation:

First you find the even amount of boys and girls out of 386

386 divided by 2 = 193

Then you subtract 32 boys and add the 32 to girls since there are 32 more girls than boys

(boys) 193 - 32 = 161

(girls) 193 + 32 = 225

So there are 161 boys and 225 girls

x= -10

Step-by-step explanation:

the sum of the angles are 180. so subtract 50 and 60 from 180. That gives you 70. then solve x+80=70

Answer:

x = -10°

Step-by-step explanation:

60 + 50 + (x+80) = 180

190 + x = 180

x = -10

Answer:

=28

Step-by-step explanation:

3(8)-(-2)2

24- -4

=28

The value of the expression 3x - y² when x = 8 and y = -2 is -12.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

3x - y²

Substitute x = 8 and y = -2

3 x 8 - 9(-2)²

24 - 9 x 4

24 - 36

-12

Thus,

The value of the expression is -12.

B. Ramp with a length of 200 feet and a height of 50 feet.

Step-by-step explanation:

When it comes to slope, y is on top and x is on the bottom. The fraction gives us a ratio. In this case, the x is 4 times bigger than the y. In this instance, the length of the ramp is 4 times bigger than the height of the ramp.

Answer:

V is about 59335.5 cubic feet

Step-by-step explanation:

The formula to find the volume of a sphere is V=4/3πr^3.

If the radius is 24.2, we just need to substitute numbers into the equation.

V=4/3(3.14)(24.2^3)

V=4/3(3.14)(14172.488) **Find 24.2 cubed**

V=(4*14172.488)/3*3.14

V=(56689.952)/3*3.14 **Multiply the numerator**

V=18896.65067*3.14 **Divide the numerator by the denominator**

V=59335.48309 **Multiply by the simplified pi**

V is about 59335.5 cubic feet

It's a bit long of work but I hope I was able to have helped! Good Luck!

Answer:

The volume of given sphere is 59,335.5 cubic feet

Step-by-step explanation:

Given that

Radius of sphere=r= 24.2 feet

The volume of a sphere is calculated by the formula:

[tex]V = \frac{4}{3}\pi r^3[/tex]

We can use 3.14 or 22/7 for the value of pi

Putting the values, we get

[tex]V = \frac{4}{3} * 3.14 * (24.2)^3\\= \frac{12.56}{3} * 14,172.488\\=\frac{178,006.44928}{3}\\=59,335.48309[/tex]

Rounding off to nearest tenth of cubic feet

59,335.5 cubic feet

Hence,

The volume of given sphere is 59,335.5 cubic feet

Answer:

The sentence you have can be expressed in algebra (using x as 'the number'):

2x + 5 = x / 3.  (We add 5 to the left side because that product is less than the right side.)

Now all you have to do is to combine the x terms on one side of equation, putting the constant on the other side of the equation, and solve for x.

or

Let the unknown number that we are solving for be x.

The product of a number and 2  means 2*x

5 less than the quotient of a number and 3 means x/3 - 5.

So,

 2*x = x/3 - 5   subtract x/3 from both sides of the equation

2x - x/3 = -5 , now find the least common denominator for the left side of the equation

6x/3 - x/3 = -5

(6x - x)/3 = -5

5x/3       = -5, now multiply both sides of the equation by 3

5x          = -15  now divide both sides of the equation by 5

x = - 3. So the number is -3.

Step-by-step explanation:

Building an equation and solving for the number, it is found that the number is [tex]x = -\frac{3}{2}[/tex]

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

Equal, thus:

[tex]2x = \frac{x}{5} - 3[/tex]

Multiplying everything by 5:

[tex]10x = x - 15[/tex]

[tex]9x = -15[/tex]

[tex]x = -\frac{15}{9}[/tex]

[tex]x = -\frac{3}{2}[/tex]
