3/2=x/1

3=2x

x=3/2

x=1.5

so the unit rate of price per melon is 1.5

Answer:

Step-by-step explanation:

unit rate is another way of saying  "slope of the line"

3/2 is the slope of the line..just from inspection of the graph

1.5  is another way to say  3/2  and that's how me might normally say the cost of one watermelon... it's a  $1.50 so the unit rate is 1.5 units.. and here the units are dollars

Answer:

Total weight = 1,500 tons

Step-by-step explanation:

Given:

l = 5 ft

b = 5 ft

h = 6 ft

One cubic foot weighed = 0.1 tons

Find:

Total weight

Computation:

Volume = lbh

Volume = (5)(5)(6)

Volume = 150 ft³

Total weight = Volume / 0.1

Total weight = 150 / 0.1

Total weight = 1,500 tons

Step-by-step explanation:

I think the correct answer would be C since you are using lines and angles but I am not 100 percent sure. Also because A and B wouldn't make since because it is adding.

Answer:

c to the power of 5 x c = c⁶

Step-by-step explanation:

We need to find the expression for c to the power of 5 x c.

c to power 5 is : c⁵

Now, multiply c⁵ and c.

c⁵ × c = c⁵⁺¹

= c⁶

So, the final expression is c⁶. Hence, this is the required solution.

4/5

Step-by-step explanation:

32/40

Both can be divisible by 4

32 ÷ 4 = 8

40 ÷ 4 = 10

8/10

8 and 10 can be simplified again by 2

8 ÷ 2 = 4

10 ÷ 2 = 5

4/5

This cannot be simplified anymore, to check just divide.

32/40 = 0.8

4/5 = 0.8

The simplified form of 32/40 is 4/5.

To simplify the fraction 32/40, we can find the greatest common divisor (GCD) of the numerator (32) and denominator (40) and divide both by that value.

The GCD of 32 and 40 is 8. By dividing both the numerator and denominator by 8, we can simplify the fraction:

32 ÷ 8 = 4

40 ÷ 8 = 5

Therefore, the simplified form of 32/40 is 4/5.

Step-by-step explanation:

Find the value of c so that the polynomial p(x) is divisible by (x−3)

p(x)=−x^3+cx^2 −4x+3

if p is p(3)=-(3)^3 +c(3)^2 -4(3) +3

Answer:

The missing angle is 50 and x=6

Step-by-step explanation:

So if all three angles of a triangle add up to 180 degrees, you would simply subtract 180-70-60 to find the missing angle, and from there you put in the equation 8x+2=50, you would do a step by step process get the x by itself on one side. first subtract 2 from both sides to remove it from one, making the equation 8x=48 and than divide both sides by 8 to remove it from the x making the answer x=6. :3

Answer:

x=6

Step-by-step explanation:

Ok so to do this you need to know if you add up all the sides of a triangle [This is for triangles] you get 180 every time.

So you already have two given angels. 70 and 60.

Lets make it an equation.

70+60+8x+2=180

It looks long and hard but we can simplify this if we go ahead and add up all the common factors. In this case would be all the numbers with no variables.

132+8x=180

You don't add the 180 because its on the opposite side of the equation.

Now you need to get the variable alone. To do that you need to do the opposite operation. In this case, that would be subtraction

132(-132)+8x=180(-132)

8x=48

Divide the 8.

x=6

Answer:

Greatest growth was between : year 3 and year 4

Percentage growth was about 32%

Step-by-step explanation:

Given the data:

Year : ______1 ____ 2 _____ 3 _______ 4

Students: __ 14 ___ 19 _____ 25 ______ 33

Number of students :

Year 1 & year 2 = 19 - 14 = 5

Year 2 & year 3 = 25 - 19 = 6

Year 3 & year 4 = 33 - 25 = 8

Hence,The two years at which the greatest growth was observed is between year 3 and year 4.

Percentage growth :

((33 - 25) / 25) * 100%

(8 / 25) * 100%

0.32 * 100%

= 32%

Answer:

We have 2 2/3 ( 3/4s) in 2

Step-by-step explanation:

How many 3/4s are in 2? Write a multiplication equation and a division equation that can be used to answer the question.

a) Multiplication equation

= 2 × 4/3

= 8/3

= 2 2/3

b) Division Equation

= 2 ÷ 3/4

= 2 × 4/3

= 8/3

= 2 2/3

Answer:

B

Step-by-step explanation:

Since ∠ E = ∠ F then the triangle is isosceles and DF = DE, that is

6x = x + 2y ( subtract x from both sides )

5x = 2y ( subtract 2y from both sides )

5x - 2y = 0 → (1)

and perimeter = 29, that is

6x x + 2y + 5x - y = 29 , simplifying

12x + y = 29 → (2)

Multiply (2) by 2

24x + 2y = 58 → (3)

Add (1) and (3) term by term to eliminate y, that is

29x = 58 ( divide both sides by 29 )

x = 2

Substitute x = 2 into (2) and evaluate for y

12(2) + y = 29

24 + y = 29 ( subtract 24 from both sides )

y = 5

Thus

FE = 5x - y = 5(2) - 5 = 10 - 5 = 5 → B

Answer:

The two expressions are;

1) -8 ft. + 3 × 6 ft. = 12 feet

2) -6 ft. + 2 × 5 ft. + 8 ft. = 12 feet

Step-by-step explanation:

The given parameters are;

The lengths in feet Cecil can travel = 5 feet, 6 feet, and 8 feet

The distances Cecil can travel forward = (positive 5, 6, 8)

Backwards Cecil can travel distances of (-5, -6, -8)

Cecil can go forward past the ladder and return back

Therefore, the number expressions by which Cecil can cross a tightrope 12 feet long are;

1) -8 ft. + 3 × 6 ft. = 12 feet

Which is to go back 8 feet and then to go forward 6 feet three times

2) -6 ft. + 2 × 5 ft. + 8 ft. = 12 feet

Which is to go back 6 feet then to go forward in 5 feet two times and then in forward again in 8 feet.

Answer:

Both of them are correct.

The perimeter is found by adding up all four sides. If you notice, one of them is width and one of them is length. A rectangle has four sides, two width and two length.

l= length and w=width so P=2l+2w.

But, we can combine them by factorizing 2l+2w.

Lets see what we can pull out. We can only pull out 2.

2(l+w)=2l+2w.

2(l+w)=P

Both of them are correct.
