How many solutions does this system have? 3x+ 5y=-9

Answer:

5

Step-by-step explanation:

The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.

Answer:

x = 8

Step-by-step explanation:

2x+5=21

Step 1: Subtract 5 from both sides.

2x+5−5=21−5

2x=16

Step 2: Divide both sides by 2.

2x /2 = 16 /2

x = 8

Answer:

x = 8

Step-by-step explanation:

2x + 5 = 21

2x = 21 - 5

2x = 16

x = 16/2

x = 8

Answer:

39

Step-by-step explanation:

If you subtract 14 from my number and multiply the difference by -4, you should get -100.

You need to setup the equation that is being given to you.

Subtract 14 from my number.

x - 14

Multiply the difference by -4

(x-14) * -4

You should get -100.

(x-14) * -4 = -100

Solve for x

(Elise's number is X, the missing number).

[tex]-4(x-14) = -100\\-4x+56 = -100\\-4x=-156\\x=39[/tex]

Elise's number is 39.

Answer:

(x - 12)(x + 4)

Step-by-step explanation:

The two numbers have equal the b term which is -8

You know you have to subtract to get your answer because there is a minus sign in front of the c term

Find what factors of 48 subtract to = -8

-12 + 4 = -8

the 8th term of the geometric sequence 8, 16, 32 is 1024

we know that

geometric sequence 8, 16, 32

the question is

the 8th term

the answer is

first we have to find the ratio

[tex] \sf r= \frac{ U_2}{U_1} \\ \sf r= \frac{ 16}{8} \\ \sf r = 2 [/tex]

than, we have to find the 8th term

[tex] \sf U_n = ar^{n-1} \\ \sf U_8 = 8 \times 2^{8-1} \\ \sf U_8 = 8 \times 2^7 \\ \sf U_8 = 8 \times 128 \\ \bold {\sf U_8 = 1024} [/tex]

Answer:

3(k-6)

Step-by-step explanation:

I did it on i-Ready and got it right!

A common factor of 3k and 18 that is greater than 1 is 3.

An expression that shows 3k minus 18 is 3(k)-3(6).

An expression that is equivalent to 3k - 18 can be written as follows:

3(k - 6)

Given is an expression 3k-18 we need to an expression that is equivalent to it,

Let's break it down to understand why this expression is equivalent to 3k - 18:

Distributive Property: The expression 3(k - 6) can be expanded using the distributive property, which states that for any real numbers a, b, and c: a(b + c) = ab + ac.

In this case, a is 3, and b is k while c is -6. So we can apply the distributive property as follows: 3(k - 6) = 3k + 3(-6).

Simplification: The term 3(-6) can be simplified to -18, so the expression becomes 3k - 18.

Therefore, the expression 3(k - 6) is equivalent to 3k - 18 because both expressions yield the same result when evaluated for any value of k.

Answer: 1120

Step-by-step explanation:

Since 12 out of every 180 frogs in the popluation have spots on their back, this means that (180 - 12) = 168 do not have spot on their back. This can be represented in a fraction as:.= 168/180 = 14 / 15

With a study of a population of 1,200 frogs, the number of frogs that do not have a spots on their back will be:

= 14/15 × 1200

= 1120

Answer:

72.1 hours

Step-by-step explanation:

Let the number of hours be represented as: x

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.

Convert 2 7/8 pounds to decimal = 2.875pounds

Hence:

252 - 2.875x

Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.

Convert 3 1/3 pounds to decimal = 3.333 pounds

Hence:

285 - 3.333x

How many hours until they have the same amount of fruit left?

This calculated by equating both equation together

252 - 2.875x = 285 - 3.333x

Collect like terms

-2.875x + 3.333x = 285 - 252

0.458x = 33

x = 33 / 0.458

x = 72.052401747 hours

x ≈ 72.1 hours

They would have the same amount of fruit left after 72.1 hours

Answer:

12.5%

Step-by-step explanation:

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?

The formula for Percentage Decrease =

Decrease in price/ Initial price × 100

Decrease in price = $10

Initial price = $80

Hence:

$10/$80 × 100

= 12.5%

Hence, the percentage the price will be decreased by before tax is 12.5%
