what is an equivalent expression to m+m+m+m that is a sum of two terms. PLEASE HELP ME FAST!!!!!!!

Answer:

The answer is -2r + 8.

Step-by-step explanation:

1) Simplify 1/5(5r + 10) to 5r + 10/ 5.

[tex] \frac{5r + 10}{5} - 3(r - 2)[/tex]

2) Factor out the common term 5.

[tex] \frac{5(r + 2)}{5} - 3(r - 2)[/tex]

3) Cancle 5.

[tex]r + 2 - 3(r - 2)[/tex]

4) Expand by distributing terms.

[tex]r + 2 - (3r - 6)[/tex]

5) Remove parentheses.

[tex]r + 2 - 3r + 6[/tex]

6) Collect like terms.

[tex](r - 3r) + (2 + 6)[/tex]

7) Simplify.

[tex] - 2r + 8[/tex]

Thus, the answer for this equation is -2r + 8.

Step-by-step explanation:

Answer:

Step-by-step explanation:

2/3 x 9/10

=(2x9)/ (3x10)

=18/30

The simplest form of 18/30 is 35.

How I got this answer: First you need to write out your equation, Then you need to multiply like so, Take the first number of your first equation and multiply it by the first number in the second equation then do that for your second like this (2x9) and take (3x10) mulitply both and you get 18 for the first then 30 for the second, if you need that in simplest form. then it will be 35.

Step-by-step explanation:

When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised to the power of 6, and so you would multiply 3 and 6 to find the new power.

Step-by-step explanation:

Answer:

1) 63cm²

2)28.27cm²

(dont put the cm² in your answer though since its already there)

Step-by-step explanation:

Surface area of the cardboard part formula :

Base × Height

you have the radius going half way so add another 3cm to make it 6cm so you have the full length

6 x 10.5= 63cm²

Plastic part of the can :

[tex]\pi \: r^{2} [/tex]

3cm is your radius so.

[tex]\pi \times 3 ^{2} = 28.27433388[/tex]

but its asking you to round to the nearest hundredth so

28.27cm²

===============================================

Work Shown:

Beach ball

V = volume of sphere

V = (4/3)*pi*r^3

V = (4/3)*3.14*(6)^3 .... the beach ball has diameter 12, so radius is 6

V = 904.32

V = 904 cubic inches is the approximate volume of the beach ball

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

Toy ball

V = volume of sphere

V = (4/3)*pi*r^3

V = (4/3)*3.14*(3)^3 .... the toy ball has diameter 6, so radius is 3

V = 113.04

V = 113 cubic inches is the approximate volume of the toy ball

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

Divide the two volumes to find that 904/113 = 8

This means that the beach ball is 8 times greater in volume compared to the toy ball

We can say

[tex]\text{Beach ball volume} = 8*\left(\text{toy ball volume}\right)[/tex]

The beach ball's volume is 7238.23and if we round that would be 7238 and the volume for the toy ball is 904.78 and if we round that it would be 905.So, it's around 7 times greater. The difference after they are rounded is  6,333.

Hope this helps.

60 minutes = 1 hour

4800 × 60 = 288,000

Answer:

$12,$11,$10,$9

Step-by-step explanation:

As the starting price is $12, the first piece of information they give you is the number of cans + the discount each one gives, meaning that the table should have two titles being cost and cans. The number of cans should be at the top with the price being put below for example.

cans:  0    2   4    6

cost:  12   11   10   9

that is the table; the equation to figure this out would be

if you say that 1 can is = to "x"

then the equation becomes much easier to write down and you can simply write it down for each price

cost = 12

cost = 12 - 2x = 11

cost = 12 - 4x = 10

cost = 12 - 6x = 9

making x worth 0.5

Answer:

160 tiles

Step-by-step explanation:

1000cm×900cm=900000cm²

75cm×75cm=5625cm²

900000cm²÷5625cm²=160 tiles

Answer:

180 + s <= 450; s <= 270

Step-by-step explanation:

s = amount of money spent on music.

max amount that can be spent on s = 450 - 180 = 270 so s <= 270.

Answer:

SQUARE

Step-by-step explanation:

If Quadrilateral MNPQ has vertices M(4,0), N(0,6), P(-4,0) and Q(0, -6).

Find the following MN,  NP, PQ and MQ

Using the formula for calculating the distance between two points

MN = √(6-0)²+(0-4)²

MN = √6²+4²

MN = √36+16

MN = √52

MN = 2√13

NP = √(0-6)²+(-4-0)²

NP = √6²+4²

NP = √36+16

NP = √52

NP = 2√13

PQ = √(-6-0)²+(0-(-4))²

PQ = √6²+4²

PQ = √36+16

PQ = √52

PQ = 2√13

MQ = √(-6-0)²+(0-4)²

MQ = √6²+4²

MQ = √36+16

MQ= √52

MQ = 2√13

Since the length of all the sides are equal, hence the shape is a SQUARE

so that means that highest it could carry would be 31 boxes because 32 would go over the weight limit

Answer:

x = 4

Step-by-step explanation:

To solve, we need to isolate x.

Start by moving the 20 to the other side by subtracting it from both sides.

2x = 8

Since x is being multiplied by 2, we need to divide both sides by 2 to move it to the other side.

x = 4

Linear expression - The area of rectangle is (7x + 14) square inches.

An algebraic expression known as a linear expression has terms that are either constants or variables raised to the first power. Alternatively stated, none of the exponents can be greater than 1. Both positive and negative values can be used as coefficients. The exponent is important. Polynomial with the variable raised to the first power, also known as the linear expression

Using, Area of a rectangle = Length × width

Length = 7 inches

Width = (x + 2) inches

Area of a rectangle = Length X Width

                             = 7 × (x + 2)

                             = (7x + 14) square inches

Hence, Area of a rectangle = (7x + 14) square inches
