4(x+15) = 2(2x+25) has how many solutions?

Answer: hewo, there! your answer is below

x= -5/4

or x= 8

Step-by-step explanation:

step 1: Subtract 27x+40 from both sides.

4x2−(27x+40)=27x+40−(27x+40)

4x2−27x−40=0

Step 2: Factor left side of equation.

(4x+5)(x−8)=0

Step 3: Set factors equal to 0.

4x+5=0 or x−8=0

hope this helps you

Answer:

the dimensions would b 10 10 and 10

Answer:

24

Step-by-step explanation:

I guessed and checked but 24 -18 is 6 and 6 times 4 is 24

M + 18 = 4M

18 = 4M - M

18 = 3M

M = 18/3 = 6

4M = 4(6) = 24 sold by Luke

Step-by-step explanation:

Answer:

13.8

Step-by-step explanation:

Recall the trigonometric ratios

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

Now lets look back at the question

We are given an angle and its adjacent side length (11) and we need to find the hypotenuse

The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x

( remember that cosine = adjacent over hypotenuse )

[tex]cos(37)=\frac{11}{x}[/tex]

step 1 multiply each side by x

[tex]cos(37)*x=xcos(37)\\\frac{11}{x} *x=11[/tex]

now we have [tex]xcos(37)=11[/tex]

step 2 divide each side by cos(37)

[tex]\frac{xcos(37)}{cos(37)} =x\\\frac{11}{cos(37)} =13.77349\\[/tex]

we're left with x = 13.77439

Our last step would be to round to the nearest tenth

We would get that the answer is 13.8

Answer:

G) x = 13.8

Step-by-step explanation:

cos 37° = adj/hyp = 11/x

0.7986x = 11

x = 13.8

Answer:

4^11

Step-by-step explanation:

[(4^3)(4^4)]÷(4^1+4^-4)

using laws of indices

(4^3)(4^4)=4^(3+4)

=4^7

(4^1 +4^-4)=4^(1-4)

=4^-3

4^7/4^-3,recalling about laws of indices if the exponentials are dividiy ,you subtract the powers give their base is equal

4^7/4^-3=4^(7-(-3)

=4^(7+3)

=4^11

Answer:

Shop A = 113 pence

Shop B = 101 pence

Step-by-step explanation:

Given :

Shop A :

5kg for £5.65

Shop B:

2kg for £2.02

Price per kg :

weight / price

100 pence = £1

Shop A :

Price of 1kg :

5.65 / 5 = £1.13 = 113 pence

Shop B:

2.02 / 2 = £1.01 = 1.01 * 100 = 101 pence

Answer:

x----------> the length of the room

y----------> the width of the room

we know that

x*y=120---------> equation 1

y=(5/6)x--------> equation 2

substitute 2 in 1

x*[(5/6)x]=120------> (5/6)x²=120-----> x²=120*6/5-----> x²=144

x=12 ft

y=(5/6)*12-----> y=10 ft

the answer is

the dimensions of Winnie's bedroom are

the length of the room is 12 ft

the width  of the room is 10 ft

Plug in 6 in place of x in the expression

1/2x+2

1/2(6)+2

3+2

5

Answer:

5

Step-by-step explanation:

We are given the expression 1/2x + 2 and are asked to find the value when x = 6.

To solve, all we need to do is to substitute x with 6 :

1/2(6) + 2

Multiply 6 by the 1 in the fraction :

6/2 + 2

Divide 6 by 2 :

3 + 2

Add :

5

Answer:

a. $6 =  ($500 + $2q) / q

b. 125

Average cost =  ($500 + $2q) / q

($500 + $2x 125) / 125 = $6

Step-by-step explanation:

Average cost = total cost / quantity produced

total cost = fixed cost + variable cost

Fixed costs are costs that do not vary with output. e.g. the cost of the logo

Variable costs are costs that vary with production e.g. cost of printing and cutting

Variable cost = $2 x quantity of parking ticket sold

let q =  quantity of parking ticket sold

variable cost = 2q

$6 = ($500 + $2q) / q

to determine the number of parking ticket to be sold for average cost to be $6, take the following steps

Multiply both sides of the equation by q

6q = 500 + 2q

collect like terms

6q - 2q = 500

4q = 500

q = 125

125 tickets have to be sold for average cost to the $125

to justify the answer, replace 125 in the first equation to confirm if $6 would gotten as the average cost

($500 + $2q) / q

($500 + $2x 125) / 125 = $6

Answer:

The answer is the letter D

Step-by-step explanation:

The sum of 2t and 2 could be written as:

[tex]a=2t+2[/tex]

Now, the twice of the cube of s will be:

[tex]b=2s^{3}[/tex]

Finally, the quotient between a and b will be:

[tex]\frac{a}{b}=\frac{2t+2}{2s^{3}}[/tex]

Therefore the answer is the letter D

Answer:

39.6 cm²

Step-by-step explanation:

The formula for the area of a trapezoid is given as:

Area of a Trapezoid = 1/2(a + b) h

Where, from the question:

a = 8.9 cm

b = 5.5 cm

h = 5.5cm

Hence,

1/2 (8.9cm + 5.5cm) × 5.5cm

= 1/2 × 14.4 cm × 5.5 cm

= 39.6 cm²

Area of the Trapezoid = 39.6 cm²

~

First, distribute 10 to all terms within the parenthesis:

10(6x + 8)

10 * 6x = 60x

10 * 8 = 80

60x + 80

Next, Add like terms. Like terms are terms with the same amount of the same variable:

8x + 60x + 80

(8x + 60x) + 80

68x + 80

68x + 80 is your answer.

~

Answer:

68x + 80

Step-by-step explanation:

To solve the following problem,

8x + 10 ( 6x + 8 )

First, distribute the (10), multiply every term int he parenthesis by the term outside of it,

8x + 10(6x + 8)

8x + (10)(6x) + (10)(8)

Simplify,

8x + 60x + 80

68x + 80

405 gallons of water in the tank in 45 minutes.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

Given that A water tank is filled with a hose.

The table shows the number of gallons of water in the tank compared to the number of minutes the tank was

being filled.

The line of best for this data is g = 9m - 0.17.

We need to find when it is 45 minutes.

We have to put m value as 45 to find the number of gallons

g=9(45)-0.17

g=405-0.17

g=404.83

Hence, 405 gallons of water in the tank in 45 minutes.
