what does x equal in this y=2x + 3

Answer:

4 × 3

−−−− = 6cm²

2

6 × 3 = 18cm²

10 × 5 = 50cm²

50 + 18 + 6 = 74cm²

Answer:

The mean is 7.61.

The median is 7.31

There is no mode

Step-by-step explanation:

4.7+8.51+6.5+7.42+9.64+7.2+9.3 = 53.27

53.27/7 = 7.62

( 7.42 + 7.2 ) / 2 = 7.31

Have a great day! :)

Answer:

The mean should be 12.55

and median would be 8.51 i believe

18 ÷ 3.99 = 4.511278195

Round 4.511278195 to the nearest hundredth = 4.51 per pound

Answer:

The greatest number of sales kits that Marco can make should be 6, with each kit having 1 tile sample and 2 carpet samples.

Answer:

1 1/27 = 28/27

Step-by-step explanation:

First you evaluate your parenthesis, and to do that you need to find the Least Common Denominator of 2/3 and 2/9. The least common denominator would be 9. 3 x 3 = 9 so you multiply 2 x 3 = 6. 6/9 - 2/9 = 4/9. 7/3 x 4/9

7 x 4 = 28

3 x 9 = 27

28/27 = 1 1/27

Hey there!

7/3 * (2/3 - 2/9)

= 7/3 * 4/9

= 7(4) / 3(9)

= 28 / 27

≈ 1 1/27

Therefore, the answer should be:

28 / 27

OR

1 1/27

Either should work because they are both equivalent to each other.

Good luck on your assignment & enjoy your day!

Answer: 2070 grams

Step-by-step explanation:

2.5kg of sugar translates to 2500 grams. 2500 grams minus 430 grams is 2070 grams. Therefore, she has 2070 grams left :)

Answer:

  C. 4 × ( 25 ÷ 5 )

Step-by-step explanation:

The wording "the quotient of A and B" means A÷B. A value is 4 times as great if it is multiplied by 4.

__

The quotient of 25 and 5 is (25 ÷ 5).

The expression that represents a value 4 times as great is this quotient multiplied by 4:

  4 × (25 ÷ 5)

Answer:

[tex]144 in^{2}[/tex]

Step-by-step explanation:

We can see in the figure that you have 4 triangles, all congruent, and 1 square in the middle. The measure of the square is 8x8, so first find the area of that, 64. Then, we only need to find the area of 1 triangle and multiply that by 4, as you have 4 triangles in the figure. The area of a triangle is (base×height)/2 so fill in the values. The base is 8 in, and the height is 5 in. 5×8 is 40, so we divide that by 2 and get 20. Then multiply this by 4, and you get 80. Now, take your original area of the square, and add it to the area of the 4 triangles. 64+80=144

Hope this helps!

I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.

Answer:

the one you are currently clicking on (you're correct :) )

Step-by-step explanation:

For the item you are currently clicking on, there are three columns--each with five rectangular sections. Each of the three columns--as we can see on the label to the left, is equal to 1. So, the five split pieces must all combine to stack up to 1. This means that 1 must be divided amongst 5 pieces, so we divide 1 by 5: 1/5.

You are trying to find the model that represents 2/5 (times 3, so it will have three rows). For the model you are clicking on, each column is showing two rectangles being there. This means that you have two sections of 1/th--or, 2/5ths present.

This means that you have the fraction of 2/5th, and you have it three times, so it represents three 2/5ths fractions, or 3 x 2/5.

(Remember, multiplication is repeated addition. So, 3 times of something means that its there 3 times, you have three 2/5ths)

Answer:

e = 126

Step-by-step explanation:

Both triangles are isosceles triangles. Therefore in the smaller triangle, there are two angles that are equal to 42 degrees (the other one is next to e)

42 + 42 = 84

there are 180 degrees in a triangle

180 - 84 = 96

So the last angle in the triangle (The little one) is equal to 96 degrees.

The rule for cyclic quadrilaterals is that the two opposite angles equal 180. So the angle opposite 96 degrees will be equal to:

180 - 96 = 84

As the larger triangle is also an isosceles (as mentioned above), two angles will be equal to each other. The two angles that are equal are at the bottom left. As one of them is equal to 84, the other is also equal to 84. This means the last angle (the one at the top) is equal to:

180 - (84 + 84) =

180 - 168 = 12

Angles on a straight line always equal 180 degrees. So 'e' is equal to 180 minus the other two triangle angles on the line they all share.

180 - (12 + 42) =

180 - 54 = 126

Therefore e = 126

Answer:

11 km/h

Step-by-step explanation:

What I did is found out how fast the simulated biker traveled for 15 minutes, by doing

[tex]\frac{20}{4}[/tex] = 5

Since 15 minutes is 1/4 of an hour. Or you could do 20/60 = 1/3,  1/3 being  how much the biker traveled in a minute and multiply that by 15

15×[tex]\frac{1}{3}[/tex] = 5

Now we know that the biker traveled 5 km, now subtract 5 by [tex]2 \frac {1}{4}[/tex]

5 - [tex]2 \frac {1}{4}[/tex] =    [tex]2 \frac {3}{4}[/tex]

Julian traveled  [tex]2 \frac {3}{4}[/tex] in 15 minutes, now to find his average speed you multiply [tex]2 \frac {3}{4}[/tex] by 4 since [tex]2 \frac {3}{4}[/tex] is the distance traveled in 1/4 an hour.

[tex]2 \frac {3}{4}[/tex] × 4 = 11

11 km/h

[tex]-\frac{7}{8}[/tex]

Step-by-step explanation:

1) Use this rule: [tex]a \times \frac{b}{c} =\frac{ab}{c} .[/tex]

[tex]\frac{6\times3}{8} -5\times\frac{5}{8}[/tex]

2) Simplify 6 × 3 to 18.

[tex]\frac{18}{8} -5\times\frac{5}8}[/tex]

3) Simplify [tex]\frac{18}{8}[/tex] to [tex]\frac{9}{4}[/tex].

[tex]\frac{9}{4} -5\times\frac{5}{8}[/tex]

4) Use this rule: [tex]a\times\frac{b}{c}=\frac{ab}{c} .[/tex]

[tex]\frac{9}{4} -\frac{5\times5}{8}[/tex]

5) Simplify 5 × 5 to 25.
