Answer 15 please algebra one

1. To solve algebra equations using the distributive property, we need to distribute (or multiply) the number with each term in the expression. In that way, the brackets are removed. We can then combine like terms and solve by equations when necessary.

2. The first step is simply to apply the distribution using the distributive property : 3(3x-5x)+2=-8 applying the distributive operation we get 9x -15x or we could have simply done 3(2x)+2=-8 which gives us 6x+2=-8 and finally 6x= -8/2= -4

6x=-4 means x= -4/6 thus x= -2/3

3. Multiplication has priority over addition or subtraction thus we have first to apply the distributivity before combining the variable terms

Answer:

the common ratio is either 2 or -2.

the sum of the first 7 terms is then either 765 or 255

Step-by-step explanation:

a geometric sequence or series of progression (these are the most common names for the same thing) means that every new term of the sequence is created by multiplying the previous term by a constant factor which is called the common ratio.

so,

a1

a2 = a1×f

a3 = a2×f = a1×f²

a4 = a3×f = a1×f³

the problem description here tells us

a3 = 4×a1

and from above we know a3 = a1×f².

so, f² = 4

and therefore the common ratio = f = 2 or -2 (we need to keep that in mind).

again, the problem description tells us

a2 + a4 = 30

a1×f + a1×f³ = 30

for f = 2

a1×2 + a1×2³ = 30

2a1 + 8a1 = 30

10a1 = 30

a1 = 3

for f = -2

a1×-2 + a1×(-2)³ = 30

-10a1 = 30

a1 = -3

the sum of the first n terms of a geometric sequence is

sn = a1×(1 - f^(n+1))/(1-f) for f <>1

so, for f = 2

s7 = 3×(1 - 2⁸)/(1-2) = 3×-255/-1 = 3×255 = 765

for f = -2

s7 = -3×(1 - (-2)⁸)/(1 - -2) = -3×(1-256)/3 = -3×-255/3 =

= -1×-255 = 255

Answer:

-5000

Step-by-step explanation:

hope this helps :)

Combine like terms:

-r-10r

We can always add variables as long as they are the same. So we can not add 10x+20y. That's impossible.

We can't add 3r^2+10r. That's also impossible.

However, we have the same variable, r. So we can add -r-10r. And the answer is:

-11r

Hope this helps! :)

Hey there!

-r - 10r

= -1r - 10r

COMBINE the LIKE TERMS

= (-1 - 10r)

= -11r

Therefore, your answer is: -11r

Good luck on your assignment and enjoy your day!

Area = Length X width

Let the width (breadth) = X

The length is double so it is 2x

Area = X * 2x = 2x^2

128 = 2x^2

Divide both sides by 2:

64 = x^2

take the square root of both sides:

x = 8

The breadth = 8 meters

The length = 16 meters

Answer:

1/16

Step-by-step explanation:

Answer:

1/16

Step-by-step explanation:

To divide fractions we will need to make the 2 and 1/8 into a fraction. We can make it into 17/8 by multiplying 8 by 2 and adding 1. We can also say 34 is 34/1. We now can divide by multiplying by the reciprocal which is 1/34. So we get 17/8*1/34 = 1/16

Answer:

its 4 pizzas

Step-by-step explanation:

The number of pizzas will be a whole quantity. Then the number of pizzas ordered will be 4.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A group of 9 people are ordering pizza. Each person wants 3 slices and each pizza has 8 slices.

The total number of slices will be given as,

⇒ 9 x 3

⇒ 27

Then the number of pizzas will be given as,

⇒ 27 / 8

⇒ 3.375

The number of pizzas will be a whole quantity. Then the number of pizzas ordered will be 4.

Answer:

the diameter of a circle is 56 CM

Answer:

7 hours

Step-by-step explanation:

If you divide

171 ÷ 9

you find the $ Tammy made in 1 hour.

171 ÷ 9 = 19

So Tammy made 19 for 1 hour of work.

Then we divide 133 by 19 to find out for how many hours she has to work.

133 ÷ 19.67 = 7. So Tammy has to work 7 hours to make $133.
