Answer:

x= 7/12

Step-by-step explanation:

3/4- 1/6

18/24- 4/24

14/24

7/12

Answer:

Step-by-step explanation:

The sale price = Initial Cost - 15% of the initial Cost

The sale price = 1250 - 15/100 * 1250

The sale price = 1250 - 187.5

The Sale Price = 1062.5

Now you add on the sales tax

Cost with Sales Tax = 1062.50 + 6.5/100 * 1063

Cost with Sales Tax = 1062.50 + 69.06

Cost with Sales Tax = 1131.56 dollars.

Answer:

Caleb and Devon each bowled for [tex]10[/tex] hours and spent [tex]\$55[/tex].

Step-by-step explanation:

Equations:

Where:

System of equations:

[tex]\begin{cases}y=4x+15\\y=5x+5\end{cases}[/tex]

Solve for x

Step 1: Substitute the second equation into the first.

[tex]\implies 4x+15=5x+5[/tex]

Step 2: Subtract [tex]5x[/tex] from both sides

[tex]\implies 4x-5x+15=5x-5x+5[/tex]

[tex]\implies -x+15=5[/tex]

Step 3: Subtract [tex]15[/tex] from both sides.

[tex]\implies -x+15-15=5-15[/tex]

[tex]\implies -1x=-10[/tex]

Step 4: Divide both sides by [tex]-1[/tex] .

[tex]\implies \dfrac{-1x}{-1}=\dfrac{-10}{-1}[/tex]

[tex]\implies \boxed{x=10}[/tex]

Solve for y

Step 1: Substitute the found [tex]x[/tex] value into one of the system of equations.

[tex]\implies y=4(10)+15[/tex]

Step 2: Multiply and add.

[tex]\implies y=40+15[/tex]

[tex]\implies \boxed{y=55}[/tex]

Therefore, Caleb and Devon each bowled for 10 hours and spent $55.

Answer:

70°

Step-by-step explanation:

As, the sum of the angles in a straight line is 180°.

<E F C + < E F B = 180

70 + < E F B = 180

< E F B = 180 - 70

< E F B = 110°

Also, we know that the sum of the interior angles in a quadrilateral is 360°

So,

< E A B + < A E F + < E F B + < F B A = 360

90 + 90 + 110 + x = 360

290 + x = 360

x = 360 - 290

x = 70°

Answer:

6

Step-by-step explanation:

2 + 6 = 8

6 + 6 = 12

3 + 6 = 9

? = 6

The value of the center digit which satisfies the given scenario is 6.

A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.

Each line of the polygonal circuit's segments are referred to as its edges or sides.

If we observe the given polygon carefully every opposite side has a difference of 6 from the bigger number to the smaller number.

9 - 3 = 6.

8 - 2 = 6.

12 - 6 = 6.

So, In the center of the polygon or a hexagon, the number should be 6.

According to the question,

Cost of 1 share of ABC company = $18.75

Therefore,

Cost of 140 shares purchased by Jan in the ABC company

[tex]\sf{ = 140 × 18.75 }[/tex]

[tex]\sf{ = 2625\: dollars }[/tex]

Now,

For next 3 days, the value of share declined

[tex]\sf{ = (1 + 1.75 + 1.50)dollars }[/tex]

[tex]\sf{ = 4.25 \: dollars }[/tex]

Therefore,

The value of shares after 3 days will be

[tex]\bold{ = }{\bold{\frac{2625 - 4.25}{ 140}}}[/tex]

[tex]\bold{ = }{\bold{\frac{ 2620.75}{ 140}}}[/tex]

[tex]\bold{\red{ = 18.75\: dollars}}[/tex]

Hence, The value of share after 3 days will be $18.75 .

Explanation:

"5 hours 50 minutes" is close to "6 hours"

Let's subtract 6 hours from 17:25

It would drop us to 11:25 since 17-6 = 11.

When we subtracted 6 hours, we subtracted 10 extra minutes that we shouldn't have done. To fix this, add 10 minutes on to go from 11:25 to 11:35

Answer:

The traveler started at 11:35

Step-by-step explanation:

The question already gives you the time that the traveler arrived which is 17:25 and how long it took them to get to the desired location which was 5 hours 50 minutes. So what you need to do is subtract the time the traveler arrived to how long it took to get there.

Equation:

17:25 - 5:50

= 11:35

Answer:

$100.87 (to the nearest cent)

Step-by-step explanation:

1 gallon = 27 miles

⇒ number of gallons needed to drive 838 miles = 838 ÷ 27 = 31.0370370... gallons

1 gallon = $3.25

⇒ total cost to drive 838 miles = 3.25 x 838/27 = $100.87 (to the nearest cent)

Answer:

352.45 + 1.087x ≤ 575

Step-by-step explanation:

The most you can spend is $575, so the total you spend must be ≤ 575.

You already have a total for the pants of $352.45.

352.45 + price of hoodies ≤ 575

Let x = total price of the hoodies before tax.

The price of the hoodies with tax is

x + 8.7% of x = x + 0.087x = 1.087x

The inequality is

352.45 + 1.087x ≤ 575

Step-by-step explanation:

there are different ways you could do it using the elimination and substitution method.

Answer:

x = 1 and y = -28

(1,-28)

Elimination & Substitution method

8x + 4y = -104 →multiply by 1

4x + y = - 24 →multiply by 4

8x + 4y = -104

16x + 4y = -96

____________-

-8x = -8

x = -8/-8

Step-by-step explanation:

equation of a circle:  [tex](x - h)^2+(y-k)^2=r^2[/tex]

where (h, k) = center and r = radius

From inspection, we can see that the center of the circle = (0, 0)

and the radius = 1

[tex]\implies (x - 0)^2+(y-0)^2=1^2[/tex]

[tex]\implies x^2+y^2=1[/tex]

Substitute [tex]y=\frac{\sqrt{3}}{2}[/tex]  into  [tex]x^2+y^2=1[/tex]  and solve for [tex]x[/tex]:

[tex]\implies x^2+(\frac{\sqrt{3}}{2})^2=1[/tex]

[tex]\implies x^2+\frac{3}{4}=1[/tex]

[tex]\implies x^2=\frac{1}{4}[/tex]

[tex]\implies x=\pm \sqrt{\frac{1}{4}}[/tex]

[tex]\implies x=\pm\frac{1}{2}[/tex]
