[tex]11. \: \: - 2.5(4x - 4) = - 6 \\ - 2.5(4x) - 2.5(4) = - 6 \\ - 10x + 10 = - 6 \\ - 10x + 10 - 10 = - 6 - 10 \\ - 10x = - 16 \\ \frac{ - 10x}{ - 10} = \frac{ - 16}{ - 10} \\ x = 1.6 \\ [/tex]

[tex] \frac{1}{6} (x - 5) = \frac{1}{2} (x + 6) \\ \frac{1}{6} \times x + \frac{1}{6} ( - 5) = \frac{1}{2} \times x + \frac{1}{2} \times 6 \\ \frac{x}{6} - \frac{5}{6} = \frac{x}{2} + \frac{6}{2} \\ \frac{x - 5}{6} = \frac{x + 6}{2} \\ 2(x - 5) = 6(x + 6) \\ 2x - 10 = 6x + 36 \\ - 10 - 36 = 6x - 2x \\ - 46 = 4x \\ \frac{ - 46}{4} = \frac{4x}{4} \\ \frac{ - 23}{2} = x \\ - 11 \frac{1}{2} = x[/tex]

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

Answer:

x < -20

Step-by-step explanation:

x / -4  + 14 >20

Subtract 14 from each side

x / -4 +14-14 > 20 -14

x / -4 > 6

Multiply each side by -4, remembering to flip the inequality

Hey ! I beleive this is the answer: 27.5/100=.275

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.

Answer:

y = 21°

Step-by-step explanation:

both are parallel lines, and that means

16x - 23 = 10x + 1

16x - 10x = 23 + 1

6x = 24

x = 4

---------------------------

taking 16x - 23

16 (4) - 23 = 64 - 23 = 41

both angles value is = 41°

------------------------------------

62° + x = 180

x = 180 - 62 = 118°

----------------------------------

the sum of all the angles inside the triangle is equal to 180°

41° + 118° + y = 180°

y = 21°

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:

y=9-2x

Step-by-step explanation:

The equation that shows the relationship between the number of hours since Emmy went to bed is y = -2x + 9.

A linear equation is given by:

y = mx + b;

m is the rate of change, b is the initial value of y and y,x are variables.

Let x represent the number of hours since Emmy went to bed and y the temperature in °F. Since temperature has been dropping 2°F each hour, m = -2. Also b = 9°F, Hence:

y = -2x + 9

The equation that shows the relationship between the number of hours since Emmy went to bed is y = -2x + 9.

Step-by-step explanation:

Answer:

Hope this helps

Step-by-step explanation:

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.
