Answer:

B) 5.7

Step-by-step explanation:

The area of a square is found by multiplying its sides. Since a square has perfectly equal side lengths, you know that the square root of the area is equal to the side lengths. The area is 33. The square root of 33 is roughly 5.7. Hope that helps!

Answer: C) 2(2/5x+2) =2/5x+2 this would be the answer.

Step-by-step explanation:

Answer:

I think the answer is B. The equation has infinitely many solutions.

Step-by-step explanation:

4(3x + 4) = 15x + 12 - 3x + 4

*group like terms so 4(3x+4) = 15x - 3x + 12 + 4

*add similar elements 15x - 3x = 12x

*add the numbers 12 + 4 = 16

*Expand to 12x + 16 - 16 = 12x + 16 - 16

*You simplify 12x = 12x

*Subtract 12x from both sides

*Then Simplify which is 0

Which means Both sides are equal to 0

True for all X

Answer:

what grade r u in?

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Subtract 30 and 16. Cross out 0 and make it a 10 and 10-6= 4 then take 1 from 3 and make it a 2 and 2-1=1. It will all equal up to 14!

Answer:

8x+30+4x+18=180

12x+48=180

180-48=12x

132=12x

x=132/12

x=11

Given:

1 set requires 4 couples 8 dancers.

Total number of people at a square dance = 250.

To find:

The greatest number of sets possible at the dance.

Solution:

We have,

Total people = 250

1 set = 8 people.

[tex]\text{Number of possible sets}=\dfrac{\text{Total people}}{\text{People required for 1 set}}[/tex]

[tex]\text{Number of possible sets}=\dfrac{250}{8}[/tex]

[tex]\text{Number of possible sets}=31.25[/tex]

Number of possible sets cannot be a decimal or fraction value. So, approx. the value to the preceding integer.

[tex]\text{Number of possible sets}\approx 31[/tex]

Therefore, the number of possible sets at the dance is 31.

Answer:

The second one

Step-by-step explanation:

Because 3 times 100 is equal to 300 and this is the answer choice either the number of the value with 300

Answer:

D. 10

Step-by-step explanation:

Assuming that <COA is a right angle, we can say that the two given angles are complementary

complementary angles are angles that add up to 90 degrees

this means we can create this equation: 3x + 46 + 14 = 90

so subtract 46 and 14 from 90: 3x = 30

divide both sides by 3: x = 10

Answer:

359.13

Step-by-step explanation:

Sales tax rate: 10.5%;

Price without tax: $325 dollars;

Amount of sales tax ≈ $34.13 dollars;

Price with sales tax ≈ $359.13 dollars;

Answer:

35

Step-by-step explanation:

Let's make a system of equations for the vegetarian and chicken wraps; one for the total cost of them and one for the total amount sold.

Vegetarian wraps will be represented by variable v and chicken wraps will be represented by the variable c.

Subtract these equations.

Divide both sides by 2.40.

Substitute this value for c into the second equation.

Subtract 68 from both sides.

The number of vegetarian wraps sold amounted to 35 in total.

Answer :

Step-by-step explanation:

Then for the count we have :

→ count of vegetarian wraps + count of chicken wraps = 103

→ x + y = 103......[Equation (i)]

Then for the cost we have :

→ ❲$1.00 * x❳ + ❲$3.40 * y❳ = $266.20

Dropping the dollar signs we get :

→ ❲1.00 * x❳ + ❲3.40 * y❳ = 266.20

→ x + 3.40y = 266.20.....[Equation (ii)]

Substracting equation (i) from equation (ii) we get :

→ 0 + 2.4y = 163.2

→ 2.4y = 163.2

→ y = 163.2 ÷ 2.4

→ y = 68

Now, subsitute the value of y = 68 in equation (i) we get :

→ x + y = 103

→ x + 68 = 103

→ x = 103 - 68

→ x = 35

Let's say the surface of the pool is 0, and the diver 4 meters above represents +4, and the diver 5 meters below represents -5. Which number is closer to 0? It's 4! 4 is 4 numbers away from 0, meanwhile 5 is 5 numbers away from zero, 4 is closer to 0!

Answer:

Parallel lines

Step-by-step explanation:

The standard form of equation of a straight line is expressed as:

y = MX+c

m is the slope

Given the equations

y = 7x – 2

On comparison;

m = 7 i.e the slope of the line is 7

For the line 14x – 2y = 3

First write in standard form

-2y = -14x +3

y = -14x/-2 + 3/-2

y = 7x- 3/2

Hence the slope is also 7

Since both equations have the same slope hence they are parallel lines(Parallel lines have the same slope)

Answer:

x>10/4

Step-by-step explanation:

When you combine like terms, you get 10>4x and then divide by 4 and you get x>10/4. To plot this, you put an open point on 10/4 and highlight everything to the right of it with an arrow.

Answer:

132 units

Step-by-step explanation:

the area of triangle = 1/2 × 6 × 8 = 24 units >>>1

the area of the rectangle = 3 × 8 = 24 units >>>2

the area of rectangle(2) = (21-(9+3)) × 8 = 9 × 8 =72 units >>>3

the area of triangle(2) = 1/2 × 3 × 8 = 12 units >>>4

then , from 1 , 2 , 3 and 4 the area of the figure = 24+24+72+12 = 132 units
