-4+7/3 + 13-(-7)/5 how do i answer this

Answer:

Maggie =11

her brother= 34

Step-by-step explanation:

let the unknown be x

age of Maggie's brother: 4x-10

sum of their ages= 45

their ages=

4x-10+x =45

4x + x = 45 +10

5x = 55

x = 55/5

x= 11

age of maggie= 11

age of her brother = 4 × 11 - 10 = 34

Answer:

Maggie is 11 And Her Brother is 34

From radiciation properties:

[tex]\large{A^{\frac{P}{Q}}=\sqrt[Q]{A^P}}[/tex]

bringing to our problem

[tex]\large{6^{\frac{1}{3}}=\sqrt[3]{6^1}}[/tex]

The requried radical form of the given expression is ∛6.

Radical form is mathematical expression that represents the value under the nth roots.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

Following the rule [tex]\sqrt[n]{x} = x^{1/n}[/tex]
Similarly,
[tex]6^{1/3} = \sqrt[3]{6}[/tex]

Thus, the requried radical form of the given expression is ∛6.

The radius of the basketball is 5 inches when the  volume of a basketball is about 435 cubic inches.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The formula for the volume of a sphere is V = 4/3πr³,

where V is the volume

and r is the radius.

Let us find the formula for r

3V/ 4π =r³

Take cube root on both sides

∛3V/ 4π = r

Now let us find the radius when the volume of a basketball is about 435 cubic inches.

∛3×435/ 4×3.14 = r

1305/12.56 = r

∛103.9 = r

4.7 = r

5=r

Hence, the radius of the basketball is 5 inches when the  volume of a basketball is about 435 cubic inches.

Answer:

567-09

Step-by-step explanation:

Its not must that 3x have to be the one to be subtracted. You could take 8x as well.

But always subtract from the smaller one (in this case 3x) because its easier.

If you are subtracting 3x-3x and 8x-3x, the equation would be like

4 = 5x - 16

5x = 4+16

5x = 20

x = 4

Answer: 79

Step-by-step explanation: Lets first deal with the X. The equation would be 3 X 3 X 9. This answer is 81. Next we have 81 - 2. Therefore, our answer is 79. Do multiplacation first as M is before S in peMdaS.

Answer:

79

Step-by-step explanation:

x = 3y and y = 9

This means x = 3*9 = 27

b) around 6 years

c) around 2,500

Step-by-step explanation:

Answer:

Step-by-step explanation:

5 = 2/3 ( 8x - 6 )

to make it clearer, we can just interchange the position of LHS and RHS

2/3 ( 8x - 6 ) = 5

By transposing,

8x - 6 = 5 - 2/3

8x - 6 = 13/3

8x = 13/3 + 6

8x = 31 / 3

x = 31 / 3 × 1/8

x = 31 / 24

Answer:

27/16

Step-by-step explanation:

5=2/3(8x-6)

multiply 2/3 with 8x first then multiply 2/3 with -6

5=16/3x-4

shift 16/3x to the left hand side and bring 5 to the right hand side

-16/3x= -4+(-5)

-16/3x= -9

x= -9 divided by -16/3

x= 27/16

Answer:

x < 6

Step-by-step explanation:

It has to be a number lower than 6, because 6+6 is 12 and that creates a balanced system.

It cant be a number higher than 6, because it will drag itself down.

So we need a number that when combined, it's sum will be lower than 12

Answer:

(-2, -3)

Step-by-step explanation:

If a segment having extreme ends as [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is divided by a point (x, y) in the ratio of m:n,

x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]

y = [tex]\frac{my_2+ny_1}{m+n}[/tex]

Since, a line RT has extreme ends as R(-5, 3) and T(-1, -5) then a point S(x, y) which divides RT in the ratio of 3 : 1 will be,

x = [tex]\frac{3(-1)+1(-5)}{3+1}[/tex]

  = [tex]\frac{-8}{4}[/tex]

  = -2

y = [tex]\frac{3(-5)+1(3)}{3+1}[/tex]

  = [tex]-\frac{12}{4}[/tex]

  = -3

Therefore, coordinates of the point S will be (-2, -3).
