Answer:

$1.71

Step-by-step explanation:

Just took the test.

The cost of each juice bottle is $1.71.

Let, the cost of each juice bottle as "x".

Given:

Cost of chips = $2.94

Total cost before tax = $16.62

Isaac bought an 8-pack of juice bottles, so the total cost of the juice bottles is 8x.

The total cost of chips and juice bottles should be equal to the total cost before tax:

Cost of chips + Cost of juice bottles = Total cost before tax

$2.94 + 8x = $16.62

Now, solve for "x" the equation:

8x = $16.62 - $2.94

8x = $13.68

Divide both sides by 8:

x = $13.68 / 8

x = $1.71.

So, the cost of each juice bottle is $1.71.

Answer:

135ft^2

Step-by-step explanation:

area of trapzoid= (a+b)/(2)×h

area of traingle= 1/2(b)(h)

area of the shaded region equals (a+b)/(2)×h-1/2(b)(h)

so

(8+18)/(2)×15-(1/2)(8)(15)

Step-by-step explanation:

106 divide by 100=1.06

then the answer multiply by 1.50=1.59

An equation is formed of two equal expressions. The solution of the equation √(x+12)=x is x=4.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of the equation √(x+12)=x can be done as,

[tex]\sqrt{x+12} = x\\\\\text{Square both the sides of the equation}\\\\x+12=x^2\\\\x^2-x-12=0\\\\x^2-4x+3x-12=0\\\\x(x-4)+3(x-4)=0\\\\(x-4)(x+3)=0[/tex]

Equate each of the factors with 0,

[tex](x-4)=0\\x=4\\\\(x+3)=0\\x=-3[/tex]

Now, if we substitute the value of x in the equation given, only the value of x as 4 will satisfy the equation.

Thus, the solution of the equation √(x+12)=x is x=4.

Answer:

24

Step-by-step explanation:

Area = 216

The area of triangle = 1/2 b * h

Since height = 18 --> 1/2 b * 18

so,

216 = 1/2 b * 18

Divide both sides by 18

12 = 1/2 b

Divide both sides by 1/2, (which is the same as multiplying both sides by 2)

24 = b

Answer:

24 inches

Step-by-step explanation:

Given:

[tex]\bullet \ \ \text{Height of sign: 18 inches} \\ \bullet \ \text{Area of Yield sign: 216 inches}^{2}[/tex]

The yield sign shown here is a triangle. Therefore, the question is asking to find the base of the triangle. Keep in mind that the area of a circle is 1/2 multiplied by the base multiplied by the height.  

[tex]\implies \text{Area of yield sign} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]

Substitute the height and the area in the equation and simplify.

[tex]\implies \text{216 inches}^{2} = \dfrac{1}{2} \times \text{Base} \times 18[/tex]

[tex]\implies \text{216 inches}^{2} =\text{Base} \times 9[/tex]

Divide both sides by 9.

[tex]\implies \dfrac{\text{216}}{9} =\dfrac{\text{Base} \times 9}{9}[/tex]

[tex]\implies24 \ \text{inches} =\text{Base}[/tex]

The value of x = 110°

Step-by-step explanation:

=> x° + 90° + 90° + 70° = 360 ° { sum of angles of a quadrilateral is 360 }

=> x + 250° = 360°

=> x = 360 - 250

=> x = 110°

Answer:

36

Step-by-step explanation:

you have to isolate your variable. To do this, you add 24 to each side. On the left side its 12+24 and on the right, its 24+(-24) which then equals zero. In simple terms, x=12+24

Answer:

x = 36

Step-by-step explanation:

Add 24 to 12 because 24 is minus, so when it is moved to the other side of the equation it is plus.
