The length of a rectangle is (x-8)units, and its width is (x+11) units. Which expression can represent the area of the rectangle?

x = # of hours the DJ was booked

$90 + $60x = $300

Subtract $90 from both sides.

$60x = $210

Divide both sides by $60

x = 3.5 hours

They had the DJ for 3.5 hours

Answer:

x = orgininal angle

3x +20 = supplementary angle

1. x + (3x+20) = 180

2. 4x + 20 = 180

3. 4x = 160

4. x = 40

The orginial angle is 40

The supplementary angle is 140

Step-by-step explanation:

1. define your varibles using the words given

2. add them together to equal 180, because they are supplmentary.

3. combine like terms.

4. subtract 20

5. divide by 4

6. you find x, now plug it back into your variables at the top:

x = 40

3(40) + 20 = 140

Answer:

Step-by-step explanation:

use

i=prt

i=interest

p= principal value

r=rate

t=time

now you want to find time then it will be

t= i/pr

put values

t= 3722/(2000*7.6%)

t= 2 years

calculation is in fraction but your question given you annual interest so time will also be 2 years not in months

Answer:

5.14 is irrational

Step-by-step explanation:

This is irrational because it is a decimal and/or a fraction, and a rational number is a whole number such as 1, 7, 32.

Answer:

1/16

Step-by-step explanation:

This question involves two distinct genes; one coding for seed shape and the other for cotyledon color. The alleles for round seeds (R) and yellow cotyledons (Y) are dominant over the alleles for wrinkled seed (r) and green cotyledon (y) respectively.

In a cross between a truebreeding (i.e. same alleles for both genes) pea having round seeds and yellow cotyledon (RRYY) and a truebreeding pea having wrinkled seeds and green cotyledon (rryy), the F1 offsprings will all possess a heterozygous round seed and yellow cotyledon (RrYy).

The F1 offsprings (RrYy) will produce the following gametes: RY, Ry, rY, and ry. Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced in a ratio 9:3:3:1.

According to the question, 3/16 of the F2 offsprings will possess round seeds and green cotyledons, however, only 1 of them will be truebreeding i.e. RRyy. Hence, 1/16 of the F2 offsprings will be truebreeding for round seeds and green cotyledons.

Answer:19x

Step-by-step explanation:

Take x as the value of pennies

If there are twice as many quarters as pennies then the explanation should be

Pennies =x

Quarters =2x

If there are 4 times as many nickels as pennies then the explanation is

Pennies =x

Nickels =4x

If there are 5 times as many dimes as nickels then the explanation is

Nickels =4x

Dimes=20x

So the values of them all is

Pennies =x

Nickels =4x

Dimes =20x

Quarters =2x

So to get how many more dimes does the child have than quarters you subtract

20x-2x=19x

The Number of dimes the child has more than quarters is; 10 times more.

Let number of pennies be P

Since he has twice as many quarters as pennies, then;

Number of quarters; Q = 2P

Four times as many nickels as pennies. Then;

Number of nickels; N = 4P

five times as many dimes as nickels. Then;

Number of dimes; D = 5N = 5(4P) = 20P

Since number of quarters = 2P

And number of dimes = 20P

Then;

Number of dimes the child has more than quarters is; 20P/2P = 10

Thus, the child has ten times as many dimes as quarters

Answer:

x=0

Step-by-step explanation:

it tells you that

∠LKJ=169

∠SKJ=x+95

∠LKS=74+2x

and by the figure we know that

∠LKJ=∠LKS+∠SKJ

so we have

[tex]169=x+95+74+2x\\\\169=3x+169\\\\169-169=3x\\\\0=3x\\\\x=0[/tex]

LKS + SKJ = LKJ

Substitute the numbers into the equation above.

74 + 2x + x + 95 = 169

Combine like terms

3x + 169 = 169

Subtract 169 from both sides

3x = 0

Divide both sides by 3

x = 0

SKJ = x + 95 = 0 + 95 = 95

LKS = 74 + 2x = 74 + 2(0) = 74 + 0 = 74

LKJ = 169

LKS + SKJ = LKJ

74 + 95 = 169. This proves that x = 0

Answer:

It’s 11 inches

Step-by-step explanation:

I had the question

The equation that's represents the solution is 3x+ 7= 40.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

The perimeter of the quadrilateral is 40 inches.

The length of the fourth side is 7 inches

let the length of three equal sides are x unit each.

So, Perimeter of Quadrilateral = 40

x+ x +x + 7 = 40

3x = 33

x= 11

Hence, the equation is 3x + 7= 40.

Answer: D. 12

Step-by-step explanation:

The first step here is to find all the possible selections and the number of options for each selection:

bread: 2 options (white or wheat)

meat: 3 options (beef, ham or turkey)

cheese: 2 options (swiss or cheddar)

The total number of combinations (of different possible sandwiches that Ray can order) is equal to the product between the numbers of options for each selection, so we have:

Combinations = 2*3*2 = 12

Answer: Pizza = $2.95, Breadstick = $0.50, Juice = $1.25

Step-by-step explanation:

Let P represent the cost of a slice of pizza

and B represent the cost of breadstick

and J represent the cost of a juice drink.

EQ1: 3P + 4B + 2J = 13.35

EQ2: 5P + 2B + 3J = 19.50

EQ3: 4B + J = P + 0.30     -->     P - 4B - J = -0.30

Let's eliminate B from EQ1 and EQ2 to form EQ4:

3P + 4B + 2J = 13.35   →  1(3P + 4B + 2J = 13.35)   →   3P + 4B + 2J =  13.35

5P + 2B + 3J = 19.50  → -2(5P + 2B + 3J = 19.50)  →  -10P -  4B -  6J = -39.00

                                                                        EQ4:     -7P          -4J    = -25.65

And eliminate B from EQ1 and EQ3 to form EQ5:

               3P + 4B + 2J = 13.35  

                 P -  4B  - J = -0.30

EQ5:       4P           + J  = 13.05    

Now, eliminate J from EQ4 and EQ5 to solve for P:

-7P  - 4J = -25.65  →    1(-7P  - 4J = -25.65)   →   -7P  - 4J = -25.65

 4P  +  J = 13.05   →    4(4P  +   J =  13.05)    →    16P  +4J =  52.20

                                                                             9P          = 26.55

                                                                           ÷9             ÷9    

                                                                                    P = 2.95

Plug in P = 2.95 into EQ4 or EQ5 to solve for J:

EQ5: 4P + J = 13.05

        4(2.95) + J = 13.05

        11.80 + J = 13.05

                   J = 1.25

Plug in P = 2.95 and J = 1.25 into either EQ1 or EQ2 or EQ3 to solve for B:

EQ3: 4B + J = P + 0.30

        4B + 1.25 = 2.95 + 0.30

        4B + 1.25 = 3.25

                   4B = 2.00

                     B = 0.50

Check (since we used EQ3 to find B, use either EQ1 or EQ2):

EQ2: 5P + 2B + 3J = 19.50

       5(2.95) + 2(0.50) + 3(1.25) = 19.50

       14.75 + 1.00 + 3.75 = 19.50

                            19.50 = 19.50     [tex]\checkmark[/tex]
