Step-by-step explanation:

Answer: x = 5t - a

Step-by-step explanation:

6x + a = 5 (x + t)

expanding the bracket

6x + a = 5x + 5t

collecting like terms

6x - 5x = 5t - a

x = 5t - a

Answer:

x = 5t - a

Step-by-step explanation:

in order to make x the subject of formulae from the expression 6x+a=5(x+t)

the first step to do is to open the bracket (BODMAS).

6x+a=5(x+t)

6x + a = 5x + 5t

collect the like terms

6x-5x = 5t - a

x = 5t - a

therefore the value of x in the expression , that is expressing x interms of t and a from the expression 6x+a=5(x+t) is solved to be x = 5t - a

Answer:

21ft 4in

Step-by-step explanation:

4+4=8 3+3=6 8ft 6in

6+6=12 5+5=10 12ft 10in

8+12=20ft 10+6=16in

16-12=4 20+1=21

21ft 4in

Answer: 47.5 ft^2

Step-by-step explanation: First find the area of the rectangle using the formula length*height. This is 10*4 or 40.

Then find the area of the bottom triangle using the formula (base*height)/2. This will be (3*3)/2, which simplifies to 9/2, which is 4.5.

Then find the area of the top triangle using the same formula, which will be (2*3)/2, which simplifies to 6/2, which is 3.

Add all of these together. 40+3+4.5=47.5.

Answer: Remaining balance is $150

Step-by-step explanation:

Contact lens= $200

25% of the amount was paid

= 25/100 × 200 = $50

Out of $200 of contact lens, $50 was paid as deposit, subtract $200 from $50 to give balance.

$200 - $50 = $150

I hope this helps.

After calculating a 25% deposit on the $200 contact lenses, which is $50, the remaining balance that needs to be paid is $150.

If the cost of your new contact lenses is $200, and you left a 25% deposit upon ordering the lenses, we need to first calculate the amount of the deposit and then determine the remaining balance.

To find the deposit amount, we take 25% of the total cost:

Once we have calculated the deposit amount, we subtract it from the total cost to find the remaining balance owed:

So, after leaving a 25% deposit on the contact lenses, your remaining balance would be $150.

By decomposing the figure in simpler ones, we conclude that its area is 9 square units.

Let's read the figure from the top.

First, we can see in the top two triangles that have an area of half a square unit, then adding these two we have one square unit.

Below that, there are 4 square units inside the figure.

On the left and right sides, there are triangles of base of 1 unit and height of 2 units, then each of these triangles has an area of:

a = 1*2/2 = 1 square unit

And we have 2 of these triangles, so the total area is 2 square units.

Finally, on the bottom we can see 4 triangles like in the top part, we know that each one of these measure 0.5 square units, then the 4 add up to 2 square units.

Adding all the areas above, we see that the total area is:

A = (1 + 4 + 2 + 2) square units = 9 square units.

So the correct option is C

Step-by-step explanation:

The required simple interest is given as $17.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.

Here,
Principal = $850
Rate = 4%
Time = 6 months

Simple interest = principal × rate/100 × time / 12

                         = 850 × 4 / 100 × 6/12
                         = 850 × 0.04 × 1/2

Step-by-step explanation:

Write the ratios of erasers to cost (dropping the dollar sign) as fractions:

(number of erasers)/(price): 2/1 and 10/4

The question is if the ratios 2/1 and 10/4 are equivalent.

2/1 = 2

10/4 = 2.5

A proportion is setting two ratios equal. Here, one ratio equals 2, and one ratio equals 2.5.

  4x^2 -16

Step-by-step explanation:

As with any "what must be added" problem, you subtract the parts you have from the result you want:

  (3x^2 +4x +8) + (2x^2 -6x +3) + what = 9x^2 -2x -5

Identify the stuff on the left that is not "what" and subtract it from the equation:

  what = (9x^2 -2x -5) - (3x^2 +4x +8) - (2x^2 -6x +3)

  what = x^2(9 -3 -2) +x(-2 -4 +6) +(-5 -8 -3)

  what = 4x^2 -16 . . . . . . . must be added to give the desired sum

Your Answer Is: 0.125

The value of the expression 3/8 - 1/4 is 1/8.

To find this, you must first find a common denominator, which in this case is 8. Multiply 1/4 by 2/2 to get 2/8. Now, you are able to subtract the fractions to find your answer. 3/8 - 2/8 = 1/8. Thus meaning, 1/8 is your answer.

the cost of ketchup is $3.53 & mustard is $0.63 .

Step-by-step explanation:

Here we have , Brianna bought 3 bottles of ketchup and 2 bottles of mustard for $11.85. Logan bought 3 bottles of ketchup and 5 bottles of mustard for $13.73. We need to find the cost of each. Let's find out :

Let cost of ketchup be x and mustard be y than ,

Brianna bought 3 bottles of ketchup and 2 bottles of mustard for $11.85

We have following equation ,

⇒ [tex]3x+2y=11.85[/tex]   ..........(1)

Logan bought 3 bottles of ketchup and 5 bottles of mustard for $13.73

We have following equation ,

⇒ [tex]3x+5y=13.73[/tex]        ........(2)

Now , (2) - (1) , i.e.

⇒ [tex]3x+5y-(3x+2y)= 13.73-11.85[/tex]

⇒ [tex]3y= 1.88[/tex]

⇒ [tex]y=0.627[/tex]

Putting value of y in (1) :

⇒ [tex]3x+2(0.627)=11.85[/tex]

⇒ [tex]3x=11.85-1.254[/tex]

⇒ [tex]x=3.532[/tex]

Therefore , the cost of ketchup is $3.53 & mustard is $0.63 .

The cost of each bottle of ketchup is $3.532 and cost of each mustard is $0.626

Explanation:

Given:

3 bottles of ketchup + 2 bottles of mustard = $11.85

3 bottles of ketchup + 5 bottles of mustard = $13.73

Cost of each = ?

Let x be the cost of each bottle of ketchup

Let y be the cost of each bottle of mustard

According to the question:

3x + 2y = $11.85

3x + 5y = $13.73

Substituting both the equation, we get:

3x + 2y = $11.85

3x + 5y = $13.73

________________

-3y = -1.88

y = $0.626

Substituting the value of y = $0.626 in equation 1

3x + 2(0.626) = $11.85

3x + 1.252 = $11.85

3x = 10.598

x = $3.532

Therefore, cost of each bottle of ketchup is $3.532 and cost of each mustard is $0.626

Answer:

Probability breaks down to this basic formula:

    desired outcome    

total possible outcomes

Also, you need to know there are 13 spades in a deck of cards.

So, on your first draw, the chances of getting a spade are:

13    (desired outcome: pick one of the 13 spades)

52    (total possibilities: 52 cards in the deck)

But on your second draw, if you don't replace the card, your chances of getting a spade are:

12

51

because you only have 12 spades left, and 51 cards total.

Then, on your last draw, the chances of getting a spade are down to:

11

50

Since each of these probabilities depend on each other, you multiply them up to get your overall probability:

13 * 12 * 11 =   1,716

52    51    50    132,600

This reduces, or you can just divide to get a decimal.

10,000m²

Step-by-step explanation:

The figure can be divided into a rectangle and a triangle as shown in the attachment.

The area of the rectangular portion is

[tex] = l \times w[/tex]

[tex] = 120 \times 30[/tex]

[tex] = 3600 {m}^{2} [/tex]

The area of the triangular portion is

[tex] = \frac{1}{2} \times 80 \times 160[/tex]

[tex] = 6400 {m}^{2} [/tex]

The area of the figure is therefore

[tex] = 6400 + 3600[/tex]

[tex] = 10000 {m}^{2} [/tex]

The number is [tex]\( \frac{45}{8} \).[/tex]

Let's denote the unknown number as x. The given expression can be translated into an equation:

[tex]\[ 11 \times \left(\frac{x}{3}\right) - 15 \][/tex]

To find the number, set up the equation and solve for x:

[tex]\[ 11 \times \left(\frac{x}{3}\right) - 15 = x \][/tex]

First, distribute the 11:

[tex]\[ \frac{11x}{3} - 15 = x \][/tex]

Next, move [tex]\( \frac{11x}{3} \)[/tex] to the other side of the equation by subtracting it from both sides:

[tex]\[ -15 = x - \frac{11x}{3} \][/tex]

To combine the terms on the right side, find a common denominator (3):

[tex]\[ -15 = \frac{3x}{3} - \frac{11x}{3} \][/tex]

[tex]\[ -15 = \frac{-8x}{3} \][/tex]

Now, solve for x:

[tex]\[ x = \frac{-15 \times 3}{-8} \][/tex]

[tex]\[ x = \frac{45}{8} \][/tex]

So, the number is [tex]\( \frac{45}{8} \).[/tex]

Step-by-step explanation:

so you know that where it around angle c you use supplementry angels. this makes it 180-130=50.

you then know that the triangle is 90degrees plus 50 degrees plus x =180

90+50+z=180

140+z=180

z=40

Answer:

B) ∠z = 40°

Step-by-step explanation:

All three angles of a triangle add up to 180°. In this image, you can see that the angle ∠ACD is 130°. Because ∠ACB and ∠ACD are supplementary angles it means that their angles equal 180° when added together.

If ∠ADC = 130° then:

180° - 130° = 50°

Since we now know that ∠ACB is 50°, we can subtract our two angles from 180° to get the measurement for angle z.

180° - 50° - 90° =

180° - 140° = 40°

The perimeter of a rectangle is found by adding up the lengths of all its sides.

Explanation:

The perimeter of a rectangle is found by adding up the lengths of all its sides. In this case, the base of the glass house is a rectangle.

Let's say the length of the base is 12 meters and the width is 8 meters. To find the perimeter, we add up the lengths of all four sides: 12 + 8 + 12 + 8 = 40 meters.
