Answer:

sqrt(51)

Step-by-step explanation:

Use the Pythagorean theorem.

a^2 + b^2 = c^2

7^2 + x^2 = 10^2

49 + x^2 = 100

x^2 = 51

x = sqrt(51)

Answer: sqrt(51)

Answer:

3/10 and 2/5 = 3/10 and 4/10

1/3 and 3/4 = 4/12 and 9/12

Step-by-step explanation:

For 3/10 and 2/5

* Find the lcm (least common multiple) of the denominators which are 10 and  

 5. The multiples of 10 are: 10, 20, 30 etc and the multiples of 5 are: 5, 10 15,

 etc. So, the lcm is 10. It is the smallest multiple that the denomitaotrs share.

* Next multiply the numerators (3 and 2) by whatever number you use to

  multiply the denominator by to get 10. For 3/10, the denominator stayed the

  same, so to get 10, you need to multiply 10 by 1. Do the same for the

  numerator. 3 x 1 = 3. So, the first factor pair is 3/10.

* The second factor pair is 2/5, so we are still using the lcm of 10. So, what

  do you need to multiply 5 by to get 10? The answer is 2. Now just multiply

  the numerator (2) by 2 and you get 4. The second factor pair is now 4/10.

Answer:

15a - 10

Step-by-step explanation:

-5(-3a + 2)

-5 · -3a = 15a

-5 · 2 = -10

15a - 10

Answer:

4

Step-by-step explanation:

If you read it carefully then you'll get it :)

The total mass of the green rope will be the multiplication of length by per meter mass thus it will be 3.146kg.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

As per the given,

Length of rope = 60.5 m

Mass per meter = 0.052 kg

Total mass = 60.5 x 0.052 = 3.146kg

Hence "The total mass of the green rope will be the multiplication of length by per meter mass thus it will be 3.146kg".

Answer:

y = -2x + 10

Step-by-step explanation:

Answer:

z < 5.28

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

14.3 > 5(z - 2) - 2.1

Step 2: Solve for z

Here we see that any value z smaller than 5.28 would work as a solution to the inequality.

Answer:

1and1/4 or 1.25

Step-by-step explanation:

Step-by-step explanation:

I don't know if you are asking for a solution using the method of completing the squares.

3x²-2x-5=0

x²-⅔x-5/3=0

x²-⅔x=5/3

x²-⅔x+(-⅓)²=5/3+(-⅓)²

(x-⅓)²=5/3+1/9

(x-⅓)²=16/9

(x-⅓)²=√16/9

x-⅓=±4/3

x=⅓±4/3

x=5/3,-1

Thus (3x-5)(x+1)

Answer:

27[tex]\frac{7}{9}[/tex]  (rounded: 28)

Step-by-step explanation:

5/9 of 50 (of means multiply) = 5/9 x 50

= 27[tex]\frac{7}{9}[/tex]

Rounded: 28

Answer:

The value of y is 48.

Step-by-step explanation:

You have to substitute the values into the equation :

[tex]y = mx[/tex]

[tex]let \: m = 8,x = 6[/tex]

[tex]y = 8 \times 6[/tex]

[tex]y = 48[/tex]

Answer:

meiosis

Step-by-step explanation:

Answer:

B choice.

Step-by-step explanation:

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

[tex]y = 3x - 5[/tex]

Consider the coefficients. Therefore, from y = 3x-5 considering with the mx+b.

The value of m or slope is 3

The value of b or y-intercept is -5.

Answer:

The equation y = 70-27x can be used to determine the amount of money.

Step-by-step explanation:

Given that:

Amount Ben has in his trip fund = $70

Amount save by Ben each week = $27

Number of weeks = x

Amount of money after x weeks = y

According to given statement;

y = 70-27x

Hence,

The equation y = 70-27x can be used to determine the amount of money.

Answer:

x = - [tex]\frac{14}{3}[/tex]

Step-by-step explanation:

Given

2x + [tex]\frac{4}{3}[/tex] = - 8

Multiply through by 3 to clear the fraction

6x + 4 = - 24 ( subtract 4 from both sides )

6x = - 28 ( divide both sides by 6 )

x = [tex]\frac{-28}{6}[/tex] = - [tex]\frac{14}{3}[/tex]

Step-by-step explanation:

[tex]2x + y = 5 \\ - x + y = 2[/tex]

[tex]y = 2 + x[/tex]

[tex]2x + x + 2 = 5 \\ 3x + 2 = 5 \\ 3x = 3 \\ x = 1 \\ y = 2 + x \\ y = 3[/tex]
