-s.

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

[tex] \boxed{x = 1}[/tex]

Substitute x

4x + y = -24

4(1) + y = -24

4 + y = -24

y = -24 - 4

[tex] \boxed{y = - 28}[/tex]

Answer:

11.625 pounds

Step-by-step explanation:

x = weight of dog

7 3/4 = 2/3(x)

7 3/4 divided by 2/3 = x

x = 11.625 pounds

Answer:

11 5/8

Step-by-step explanation:

let 'd' = dogs weight

7 3/4 equals 2/3d

change 7 3/4 to an improper fraction:  31/4

to isolate 'd', each side needs to be multiplied by 3/2

31/4 × 3/2 = d

93/8 = d

11 5/8 equals dogs weight

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.

Answer:

SIMPLE INTEREST=PRT/100

P=300

R=5%

T=3

SI=300×5×3/100

SI=3×5×3

SI=45

Answer:

Principal(P) = R300 rate( r )=5% n=5 years

Total amount

= P(1+r/100)^n

= 300(1+5/100)^3

=R347. 2875

Interest

Answer:

12,746

Step-by-step explanation:

To find this answer, we need to divide by 8

Since we know that South Dakota sells 8X less than Michigan, we have to use the opposite sign (which in this case is division.)

Now, we use the equation 101,968/8 which gets us an answer of…

12,746!

Answer:

84.5

Step-by-step explanation:

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.

Step-by-step explanation:

18/24- 4/24

14/24

7/12

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:

Answer:

1.43 degrees

Step-by-step explanation:

Think of this as a triangle with an x (horizontal) value of 400 and a y (vertical) value of 10.

Using this train of thought, we can use SOHCAHTOA to find that the tan of some angle (we will use Ф to represent this angle) is equal to the opposite (vertical) value divided by the adjacent (horizontal) value.

As an equation, it looks like this: tan (Ф) = 10/400.

We can use the arctan to find Ф from this equation: arctan (10/400) = Ф

Therefore, Ф is about 1.43 degrees.

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:

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:

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:

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
