Based on the given information, Michael's age is 13, and Gabrielle's age is 26.

Let's represent Gabrielle's age as G and Michael's age as M.

Given that Gabrielle's age is two times Michael's age, we can express this relationship as:

G = 2M.

We also know that the sum of their ages is 39:

G + M = 39.

Now, we can substitute the value of G from the first equation into the second equation:

2M + M = 39.

Combining like terms:

3M = 39.

To isolate M, we divide both sides of the equation by 3:

M = 39 / 3.

Simplifying further:

M = 13.

Therefore, Michael's age is 13.

To confirm this result, we can substitute M = 13 back into the equation G = 2M:

G = 2(13).

G = 26.

So, Gabrielle's age is 26.

=total pay=(8x30)+20

=240+20=£260

=Total pay=(8x34)+bonus

300-272+bonus

300/-272 -272/-272 +bonus

bonus=£28

Step-by-step explanation:

given,

JIMMY bought,

no. of daylillies = 4

no. of shrubs = 9

total cost of all material he bought = $80

TED bought,

no. of daylillies = 12

no. of shrubs = 4

total cost of all material he bought = $148

let daylillies be x and shrubs be y

the equation is,

4x + 9y = $80 -----------(1)

12x + 4y = $148 -----------(2)

now, multiply (1) by 3 we got,

12x + 27y = $240 -----------(3)

now, subtract (2) from (3) we got,

23y = 92

→ y = 92/23 = 4

→ y = 4

therefore cost of shrubs are $4.

so, cost of daylillies,

→ 12x + 4(4) = 148

→ 12x = 148 - 16 = 132

→ x = 132/12 = 11

→ x = 11

Hence, cost of daylillies are $11 and shrubs are $4.

hope this answer helps you dear......take care and may u have a great day ahead!

Answer:

y = 3x - 8

Step-by-step explanation:

m = slope

slope = y2 - y1 / x2 - x1

4 - 1 / 4 - 3 = 3/1 = 3

m = 3

b = y-intercept

b = -8

y = mx + b

y = 3x + (-8)

y = 3x - 8

But I think this is the answer

The number of rows in the considered theater which has 3 more seats that seats that the previous row, with first row having 15 and last row having 78 seats is given by: Option D: 22

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:

[tex]a, a + d, a + 2d, ... , a + (n+1)d, ...[/tex]

Its nth term is

[tex]T_n = a + (n-1)d[/tex]

(for all positive integer values of n)

And thus, the common difference is

[tex]T_{n+1} - T_n[/tex]

for all positive integer values of n

For this case, we can use arithmetic sequence as the number of seats in each next row is 3 more than previous row, so there is constant difference.

Now, the first number is 15, so we have: a = 15,d = 3 (increasing, so positive).

Let there are 'n' row in the theater.

Then the nth term of the arithmetic sequence having a = 15 and d = 3 should be 78 (as the nth row from first to last is the last row, having 78 seats).

Thus, we get:

[tex]T_n = a + (n-1)d\\78 = 15 + (n-1)3\\78-15 =3n - 3\\\\n = \dfrac{63+3}{3} = 22[/tex]

Thus, the number of rows in the considered theater which has 3 more seats that seats that the previous row, with first row having 15 and last row having 78 seats is given by: Option D: 22

Step-by-step explanation:

Line segments can be divided into sub-segments.

The value of DF is 18

The given parameters are:

[tex]\mathbf{BE = 3x + 6}[/tex]

[tex]\mathbf{DF = 7x + 4}[/tex]

We have:

[tex]\mathbf{BE + DF = 30}[/tex]

So, we have:

[tex]\mathbf{3x + 6 + 7x + 4 = 30}[/tex]

[tex]\mathbf{10x + 10 = 30}[/tex]

Subtract 10 from both sides

[tex]\mathbf{10x = 20}[/tex]

Divide both sides by 10

[tex]\mathbf{x = 2}[/tex]

Substitute [tex]\mathbf{x = 2}[/tex] in [tex]\mathbf{DF = 7x + 4}[/tex]

[tex]\mathbf{DF = 7 \time 2 + 4}[/tex]

[tex]\mathbf{DF = 14 + 4}[/tex]

[tex]\mathbf{DF = 18}[/tex]

Hence, the value of DF is 18

Answer:

x = - 1

Step-by-step explanation:

3(x + 2) = 2x + 5 ← distribute parenthesis on left side by 3

3x + 6 = 2x + 5 ( subtract 2x from both sides )

x + 6 = 5 ( subtract 6 from both sides )

x = - 1
