Answer:

-3/2

Step-by-step explanation:

Because 3 is on the postive side and 2 is on the negative

Answer:

3/2

Step-by-step explanation:

Answer:

A = 750

Step-by-step explanation:

Start with what we know:

A = LW

L = 50

W = 15

Then we fill in the values we know into the equation to get our answer.

A = L, or 50, times W, or 15.

Our new equation is A = 50 × 15

And we solve to find our answer

A = 50 × 15 or A = 750

Answer:

2.5 cm

Step-by-step explanation:

let y represent the unknown distance

4 cm = 60 miles

y cm = 37.5 miles

we then cross multiply

4 × 37.5 = 60 x y

150 = 60 y

divide both side by 60

150/60 = 60y/60

y = 2.5cm

Answer:

False

Step-by-step explanation:

Answer:

it's actually reverse; an expression is an equation without an equal sign so false lol

Step-by-step explanation:

Given:

The expression is:

[tex]-1(2x+3)-2(x-1)[/tex]

To find:

The simplified form of the given expression.

Solution:

We have,

[tex]-1(2x+3)-2(x-1)[/tex]

Using distributive property, we get

[tex]-1(2x+3)-2(x-1)=-1(2x)-1(3)-2(x)-2(-1)[/tex]

[tex]-1(2x+3)-2(x-1)=-2x-3-2x+2[/tex]

On combining like terms, we get

[tex]-1(2x+3)-2(x-1)=(-2x-2x)+(2-3)[/tex]

[tex]-1(2x+3)-2(x-1)=-4x-1[/tex]

Therefore, the simplified form of the given expression is [tex]-4x-1[/tex].

Note: The correct option is not available.

Answer: A 128 square sm

Step-by-step explanation:

So the wedge consists of a square and a triangle. We need to find the area of both using 2 formulas:

A=1/2bh for triangle

A= l*w for square

Starting with the square 8*10=80 so the area of the square is 80 square cm

Now the triangle is 12*8/2 so = 48 square cm

So add the two to get 48+80= 128 Square centimeters which is choice A

Answer: 47cm

Step-by-step explanation:

Thw circumference of a circle is given as: = 2πr or πd

where

π = 3.142

d = diameter = 15 meters

Circumference = πd = 3.142 × 15

= 47.13 cm

= 47cm

Answer:

B

Step-by-step explanation:

f(x) = 3x - 7

g(x) = 8x + 2

f(x) * g(x) = (3x - 7)(8x + 2)     {Use FOIL method}

              = 3x*8x + 3x *2  +(-7)*8x + (-7)*2

             = 24x² + 6x  - 56x - 14      {Combine like terms}

             =24x² - 50x - 14  

The set builder notation of the inequality  - 3(7n + 3) < 6n is,

{n : n ∈ R, n > - 3 }.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, An inequality - 3(7n + 3) < 6n.

Now, distributing the terms we get,

- 21n - 9 < 6n.

- 21n - 6n < 9.

- 27n < 9.

27n > - 9.          (Think of moving the variable to the other side to make it

                                                                                                        positive).

n > - 27/9.

n > - 3.

Potted plants ordered last year = 6,57,230 (Indian Place Value System)

Pecentage of plants deducted = 10%

10% of 6,57,230 = 10/100 × 6,57,230

or, it can also be written as -

10/10 × 65,723

or,

Therefore, potted plants odered this year is 65,723

Answer:

Simplifying

3x + -5 = 3x + -10

Reorder the terms:

-5 + 3x = 3x + -10

Reorder the terms:

-5 + 3x = -10 + 3x

Add '-3x' to each side of the equation.

-5 + 3x + -3x = -10 + 3x + -3x

Combine like terms: 3x + -3x = 0

-5 + 0 = -10 + 3x + -3x

-5 = -10 + 3x + -3x

Combine like terms: 3x + -3x = 0

-5 = -10 + 0

-5 = -10

Solving

-5 = -10

Step-by-step explanation:

The solution is, solutions in the equation 3x + 5 = 3x + 10 is no solution.

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here,, we have,

#SPJ2

Answer:

36 units³

Step-by-step explanation:

The volume of a rectangular prism is given by

Volume, V = l * w * h, where

V = volume like I had stated

L = length of the prism

w = width of the prism

h = height of the prism

Going by the aforelisted parameters, we can apply them to the formula to get our answer straight

Volume, V = 3 * 6 * 2

Volume, V = 36 units³

Therefore, the volume of the prism is 36 units³

Answer:

-14°C

Step-by-step explanation:

Given that,

The mean temperature for the first 4 days in January was -4°C.

The mean temperature for the first 5 days in January was -6°C.

Mean = sum of observations/no. of observations

For first 4 days,

[tex]-4=\dfrac{S_4}{4}\\\\S_4=-16\ ...(1)[/tex]

For first 5 days,

[tex]-6=\dfrac{S_4+T}{5}\\\\S_4+T=-30\ ..(2)[/tex]

Let the temperature on 5th day is T. So,

Put S₄ = -16 in equation (2).

-16 + T = -30

T = -30+16

T = -14°C

So, the temperature on the 5th day is -14°C.
