[tex]\large \mathfrak{Solution : }[/tex]

let's solve for x :

first step : adding 7 on both sides

next step : dividing by 9 on both sides :

now, let's check for the solution by Plugging the value of x as 17 / 9 in the above equation.

we can see that the LHS = RHS, therefore our value for x is correct. i.e 17 / 9

Answer:

Area formular of a triangle :

[tex]area = \frac{1}{2} \times base \times height[/tex]

area » 48 ft

height » 8 ft

let the base the b :

substitute:

[tex]48 = \frac{1}{2} \times b \times 8 \\ \\ 48 = \frac{(b \times 8)}{2} \\ \\ 48 = b \times ( \frac{8}{2} ) \\ \\ 48 = b \times 4 \\ b \times 4 = 48[/tex]

divide either sides by 4:

[tex] \frac{b \times 4}{4} = \frac{48}{4} \\ \\ { \boxed{ \boxed{base = 12 \: \: feet}}}[/tex]

Answer:

m<JKD = 22 degrees

Step-by-step explanation:

21x + 5 + 4x + 2 = 132

25x + 7 = 132

25x = 125

x = 5

m<JKD = 4x + 2

4(5) + 2

20 + 2

22

Answer:

C. x is all real numbers.

Step-by-step explanation:

Since the domain is likely infinite, then the domain must be all real numbers so x is all real numbers.

Answer:

39,000+3x=216,000

Step-by-step explanation:

brainliest please

The equation that can be used is 216,000 = 3T + 39,000 and the number of trucks sold last year is 59,000.

Given,

Number of cars sold last year = 216,000

The number of cars sold last year = 39,000 more than three times the number of trucks sold.

Let the number of trucks sold last year = T

Write the equation of the number of cars sold last year.

The number of cars sold last year = 39,000 more than three times the number of trucks sold.

216,000 = 3T + 39,000

Find the number of trucks sold last year.

We have,

216,000 = 3T + 39,000

Subtracting 39,000 on both sides.

216,000 - 39,000 = 3T + 39,000 - 39,000

177,000 = 3T

Divide 3 on both sides.

177,000 / 3 = 3T / 3

59,000 = T

The number of trucks sold last year is 59,000.

Thus the equation that can be used is 216,000 = 3T + 39,000 and the number of trucks sold last year is 59,000.

Natalie since its constant ig

Answer:

Natalie.

Step-by-step explanation:

there is a constant pattern in the cost of shirts and the number of shirts that can be bought.

for every 1 shirt you pay $15.

thus, to determine the amount you pay for 2 shirts.

2(X)=Y {y= the total cost of 'n' shirts,X= the cost of 1 shirt.}

so this can be expressed as n15=Y

3 shirts therefore will be 3($15)= $45

Answer:

186%

Step-by-step explanation:

Looking at the squares, we can see that the first one has been completely shaded. That means that it is 100% shaded.

The second square has 86 out of 100 squares shaded, so that means that it is 86% filled.

Therefore 186% is filled by the shaded area.

Answer:

Step-by-step explanation:

a = 12 cm ; b = 8 cm and h = 6 cm

a) Area of Trapezium = [tex]\dfrac{(a+b)*h}{2}[/tex]   ,  where a and b are length of non parallel sides.

                        [tex]=\dfrac{(12+8)*6}{2}\\\\=\dfrac{20*6}{2}\\\\= 10 * 6\\\\= 60 \ cm^{2}[/tex]

b)   x    0      1        2      3       4  

     y     7       4      1      -2      -5

3x + y = 7

        y = -3x + 7

When x = 0 ;  y = 0 + 7 = 7

When x = 1 ;   y = -3*1 + 7 = -3 +7 = 4

When x = 2 ; y = (-3) *2 + 7 = -6+7 = 1

When x = 3 ;  y = (-3)*3 +7 = -9 + 7 = -2

When x = 4 ; y = (-3) *4 + 7 = -12 + 7 = -5

c) Let the consecutive even number = (2x + 2) & (2x + 4)

9 *greater number - 7 *smaller number = 46

9*( 2x+ 4 ) - 7(2x + 2)= 46

9*2x + 9*4 - 7 *2x - 7*2 = 46

18x + 36 - 14x - 14  = 46

18x - 14x + 36 - 14 = 46

           4x +  22    = 46

                      4x  = 46 - 22

                      4x =  24

                        x = 24/4

                        x = 6

2x + 2 = 2*6 + 2 = 12 + 2 = 14

2x +4 = 2*6 + 4 = 12 + 4   = 16

The consecutive even numbers are  14 & 16

Answer:

15 m and 20 m

Step-by-step explanation:

Let the width be x

Length = x + 5

Perimeter = 2(l + b)

70 = 2(x + 5 + x)

70/2 = 2x + 5

35 = 2x + 5

35 - 5 = 2x

30 = 2x

30/2 = x

15 = x

Length = x + 5 = 20 m

Breadth = x = 15 m

4 is the answer to the 1st question

Answer:

1. 11

2. 20

3. 34

4. 12.6

5. 18

6. 105

Step-by-step explanation:

We are told that ---> t = 0, x = 1.5, y = 6, and z = 23

1. y + 5

= 6 + 5

= 11

2. z - 2x

= 23 - 2(1.5)

= 23 - 3

= 20

3. 2z - 2y

= 2(23) - 2(6)

= 46 - 12

= 34

4. 2.6y - 2x

= 2.6(6) - 2(1.5)

= 15.6 - 3

= 12.6

5. 4(y - x)

= 4(6 -  1.5)

= 24 - 6

= 18

6. 4(2 + z) + 5

= 4(2 + 23) + 5

= 8 + 92 + 5

= 105

Answer:

a=5 or a=15, b=15 or b=5

Step-by-step explanation:

b=20-a

a(20-a)=75

20a-[tex]a^{2}[/tex] -75=0

-[tex]a^{2}[/tex]+20a-75=0

[tex]a^{2}[/tex]-20a+75=0

(a-5)(a-15)=0

a-5=0 or a-15=0

a=5 or a=15

b=15 or b=5

(:

Answer:

Step-by-step explanation:

 a + b = 20

Sum of roots = 20

ab = 75

Product of roots = 75

x² - (a +b) x + ab = 0

x² - 20x + 75 = 0

Sum = coefficient of x = -20

Product = 75

Factors = 15 , 5    {15*5 = 75  & 15 +5 = 20}

x² - 15x - 5x + 75 = 0  {Rewrite the middle term}

x(x - 15) - 5(x - 15) = 0

(x - 15) (x - 5)=0

x - 15 = 0    ; x -5 = 0

x = 15        ; x = 5

a = 15  ;  b= 5
