2a + 2 - 3

2a - 1

Answer:

2a-1

Step-by-step explanation:

-3a+2+5a-3

Add like terms

-3a+5a+2-3

Answer: 6 pounds of grapes

Step-by-step explanation:

There are 12 people that Joe is meant to buy for.

Each of them will receive 0.5 pounds of grapes.

All  of them will therefore need:

= pounds of grapes per person * number of people

=  0.5 * 12

= 6 pounds of grapes

Answer:

If its a true or false question its false

Step-by-step explanation:

Answer:

They are equal

Both answer is 65

Step-by-step explanation:

5x -30 = 2x +27

5x -2x = 27 +30

3x = 57

x = 57/3 = 19

5x -30 = 5(19) -30 = 65

2x +27 = 2(19) +27 = 65

Answer:

Answer:

1225 cm²

Step-by-step explanation:

Keliling persegi diberikan sebagai 4 × a

Dimana a = Panjang sisi

Keliling persegi di atas = 140

Karenanya:

4a = 140

a = 140/4

a = 35 cm

Panjang sisi bujur sangkar = 35cm

Luas persegi = (Panjang sisi) ²

Karenanya:

Luas persegi = (35cm) ²

= 1225 cm²

Luas persegi sebelum membagi adalah 1225 cm²

Answer:

B

Step-by-step explanation:

slope formula

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

we have the two points

(2,4) (3,7)

[tex]\frac{7-4}{3-2}=3[/tex]

which means the slope for line m is 3x

our equation so far looks like this

y=3x+b

plug in a set of numbers to solve for b

let's use (2,4)

4=3(2)+b

4=6+b

b= -2

which means our equation is

y= 3x-2

which is equal to

2= 3x-y

the only answer is then B

Answer:

21,872 tickets

Step-by-step explanation:

The computation of the number of tickets to be still sold is given below:

= Total people accommodated - total number of tickets sold yet

= 50,000 people - (13,520 tickets + 14,608 tickets)

= 50,000 people - 28,128 tickets

= 21,872 tickets

Answer:

x =6t

y = - 5t

Step-by-step explanation:

step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.

step 2. dos must have only 2 square rootable terms and a "-" between them.

step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!

step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!

step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!

step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!

Answer:

x=−5 and y=−7

Step-by-step explanation:

Step: Solve y=2x+3for y:

y=2x+3

Step: Substitute2x+3foryin4x−3y=1:

4x−3y=1

4x−3(2x+3)=1

−2x−9=1(Simplify both sides of the equation)

−2x−9+9=1+9(Add 9 to both sides)

−2x=10

−2x

−2

=

10

−2

(Divide both sides by -2)

x=−5

Step: Substitute−5forxiny=2x+3:

y=2x+3

y=(2)(−5)+3

y=−7(Simplify both sides of the equation)

Answer:

98 calories is the closest estimate

590 x 2 = 1180

1180 / 12 = 98.3

Answer:

the width is 360 ft

Step-by-step explanation:

The computation of the width of the flag is shown below:

Let us assume the width be x

So the length would be x + 340

And, the perimeter is 2,120 ft

So the formula is

Perimeter = 2(length + width)

2,120 = 2(x + 340 + x)

2,120 = 2x + 680 +  2x

2,120 = 4x + 680

4x = 2,120 - 680

x = 360

hence, the width is 360 ft

Answer:

12/73

Step-by-step explanation:

There are 16 + 24 + 42 + 64 = 146 marbles in the bag and 24 blue marbles.  Therefore, the probability of pulling a blue marble is 24/146 = 12/73

Answer:

Step-by-step explanation:

"y" is geometric mean

y² = 13 × 2

y = √26 ≈ 5.1

x² = 26 + 4 = 30

x = √30 ≈ 5.5

z² = 15² - 30 = 195

z = √195 ≈ 14.0

Answer:

B. 20

Step-by-step explanation:

Using the Pythagorean Theorem, you have:

[tex]a^2 + b^2 = c^2\\24^2 + 32^2 = c^2\\576 + 1024 = c^2\\1600 = c^2\\c = 40[/tex]

So you know side AB is 40 inches long. It asks the length of the midpoint to point A, so you have to do 40/2 = 20 inches

Answer:

1. $2.5

2. 2/5lb

Step-by-step explanation:

1. The blank is asking what the cost of one pound of blueberries costs and you know that two pounds costs $5, so half of 5 is 2.5. So the first blank is $2.5.

2. You know that $2.5 will get you one pound, so divide by 5 and now you know that $0.50 will get you 1/5 pound of blueberries. multiply by two and now you know that $1.00 get you 2/5 pound of berries. So the second blank is 2/5 lb.  

Answer:

1. 2.50 dollars

2. 0.2 pounds

Step-by-step explanation:

Sorry if I explain things you might not understand.

1. To find how much one pound is, you solve the equation 2 / 5 = 1 / P. You solve for P which will be 2.5 or 5/2

2/5 = 1/P

2/5 x P x 5/2 = 1 / P x P x 5/2

P = 5/2

2. To find the amount of pounds per dollar, you solve the equation 5/2 = 1/D. You solve for D which will be 2/5 or 0.2 dollars.

5/2 x D x 2/5 = 1/D x D x 2/5

D = 2/5
