Answer:

5

Step-by-step explanation:

Terrible wording on the question as the "father" is 15 the "son" is 10 and the sister is 0 or just born

J = john

S = son

X = sister

J = 2s

S = 5 + X

3(x+5) = J + 5

J = 2(5+x) = 2x + 10

3x+15 = 2x +10 + 5

x = 0

Answer:

7

Step-by-step explanation:

7 times 5 is 25 +3 is 38

The value of x is equal to 7.

There are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram.  Each type is defined accordingly to its length of sides and angles. For example,  the opposite sides for a parallelogram are equal and parallel.

Considering that the opposite sides of the  parallelogram (ABCD)  are equal and parallel, so AD=DC.  Therefore,

                                 5x+3=38

                                 5x=38-3

                                 5x=35

                                 x=7

Answer:

B. [tex]y=-\frac{2}{3}x+5[/tex]

Step-by-step explanation:

Equation of a line: y=mx+b (Where m is the slope and b is the y- intercept)

Parallel lines have the same slope.

So that means that the line will have the slope [tex]-\frac{2}{3}[/tex].

So we can write the equation of the line as y= -2/3x+b

Since it goes through the point (3,3) we can plug in 3 for x and y by doing:

[tex]y=-\frac{2}{3} x+b\\3=-\frac{2}{3} (3)+b\\3=-2+b\\b=5[/tex]

Now we know the y intercept (b) we can write the equation of the line.

[tex]y=-\frac{2}{3}x+5[/tex]

The equation of the line would be equal to y= -2/3x + 5

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

The Equation of a line: y=mx+b

Where m is the slope and b is the y- intercept

Since Parallel lines have the same slope.

So we can write the equation of the line as;

y= -2/3x+b

Since it goes through the point (3,3) we can plug in 3 for x and y

y= -2/3x+b

3 = -2 + b

b = 5

Now we know the y intercept (b) we can write the equation of the line.

y= -2/3x + 5

Answer:

The length of diagonal TU is 102 units

Step-by-step explanation:

Mathematically, the diagonals of a parallelogram bisect each other

This means that the lengths on either of the either of the sides are equal

Mathematically, we have it that;

7x + 2 = 6x + 9

7x - 6x = 9-2

x = 7

The diagonal TU has the measure of ;

(7x + 2) + (6x + 9)

7x + 6x + 2 + 9

= 13x + 11

substituting the value of x, we have

13(7) + 11

= 102

Answer:

Nina will be 18 years old when she is half as old as her mother.

Step-by-step explanation:

With the information provided, you can write an equation that indicates that Mrs. Matthews current age plus x which would be the number of years until Nina will be half as old as her mother would be equal to two times nina's age plus x, as you would have to multiply Nina's age at that time for 2 to be equal to her mother's age. The equation would be:

24+x=2(6+x)

Now, you can solve for x:

24+x=12+2x

24-12=2x-x

12=x

Finally, you  have to add the value of x plus Nina's current age to determine her age when she is half as old as her mother:

12+6=18

Acording to this, the answer is that Nina will be 18 years old when she is half as old as her mother.

Answer:

C) 42.14 cm²

Step-by-step explanation:

Recall the area formulas for a square and circle:

Area of square: A=s²

Area of circle: A=πr²

Given:

π=3.14

s=14

r=s/2=14/2=7

Therefore, the area of the square is A=14²=196 cm²

The area of the two semicircles is A=3.14(7)²=3.14(49)=153.86 cm²

Find the difference between the two areas to get the shaded area:

196 - 153.86 = 42.14

Therefore, the shaded area is 42.14 cm², making C the correct choice.

Answer:

C

Step-by-step explanation:

1) find the area of the square

A = side^2 = 14^2 = 196 cm^2

2) find the radius of the two semicircles

radius = side / 2 = 14 : 2 = 7 cm

3) find the areas of the two semicircles

A = radius^2 x 3,14 x 2 = 7^2 x 3,14 = 153.86 cm^2

4) find the area of the shaded region

196 - 153.86 = 42.14 cm^2

50d^2 - 98e^2

Factor out 2.

2(25d^2 - 49e^2)

We now factor the difference of two perfect squares within the parentheses.

2(5d - 7e)(5d + 7e)

This is as far as we can factor.

Done!

The factor of the expression into an equivalent form 50d²- 98e² would be;  2(5d - 7e)(5d + 7e)

Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

We are given that expression is given that 50d²- 98e².

Answer:

The correct option is b.

Step-by-step explanation:

To find the number of solutions, we need to solve the equation:

[tex] 5x + 3(x - 1) = 10x - x - 5 [/tex]

Let's group all the "x" on the equation.  

[tex] 5x + 3x - 10x + x = 3 - 5 [/tex]              

Now, let's solve for "x".

[tex] -x = -2 [/tex]
