Answer:

x

7x-6x=x

7-6=1 but instead of putting the one there it would just be x depending on your teacher they'd mark it wrong if you put the 1.

Answer:The answer is 14x-25=115    (B)

Step-by-step explanation:

he bought a certain amount of shirts, each being 14 dollars. So 14(how ever many shirts)- 25(the coupon) = Sales price

Answer:

b. 14x-25=115

Step-by-step explanation:

14 dollars each and 25 discount

the "each" here means the cost per cloth is 14, and total cost of the clothes Marco buy will increase depend on the amount of clothes.

Thus, it is 14x

The 25 discount represent that NO MATTER how many clothes Marco purchase, he only gets a discount of 25.  It is a independent value.

Total clothes bought - discount = total amount of money spent.

Thus, it is 14x-25=115

option B is the answer.

B)B'(3,-7)

Step-by-step explanation:

L = 56 + 4(D)

L = 56 + 4(34)

L = 56 + 136

L = 192

Total length of the road after 34 days is 192 miles

Ben earn $91 in 4 years.

Answer:

14

Step-by-step explanation:

20-6=14

x=14

hi ! x must represent 14 in order for x+6 = 20

if we insert the x which would be 14 it would be 14+6=20 :))

Answer:

The perimeter of ΔABC is 43 units

Step-by-step explanation:

An illustrative diagram is shown in the attachment below.

To find the perimeter of the triangle, we will first determine the length of the unknown sides.

First, we can determine /BC/ using the Sine rule

From Sine rule

[tex]\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}[/tex]

∴ [tex]\frac{SinA}{a} = \frac{SinC}{c}[/tex]

In the diagram, [tex]a = /BC/[/tex] and [tex]c = /AB/ = 12[/tex]

m∠A=60° and m∠C=45°

∴ [tex]\frac{Sin60}{/BC/} = \frac{Sin45}{12}[/tex]

[tex]/BC/ = \frac{12 \times Sin60}{Sin45}[/tex]

[tex]/BC/ = 6\sqrt{6}[/tex]

To find /AC/, will first determine m∠B

m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)

60° +m∠B + 45° = 180°

m∠B + 105° = 180°

m∠B = 180° - 105°

m∠B = 75°

Also, using the sine rule

[tex]\frac{SinB}{b} = \frac{SinC}{c}[/tex]

From the diagram, [tex]b = /AC/[/tex]

[tex]\frac{Sin75}{/AC/} = \frac{Sin45}{12}[/tex]

[tex]/AC/ = \frac{12 \times Sin75}{Sin45}[/tex]

[tex]/AC/ = 6 + 6\sqrt{3}[/tex]

Now,

The perimeter of ΔABC = /AB/ + /BC/ + /AC/

= [tex]12 + 6\sqrt{6} + 6+6\sqrt{3}[/tex]

= 43.09 units

≅ 43 units

Hence, the perimeter of ΔABC is 43 units.

Answer:

Using the figure above, if AB = RT and ∠R = 70°, then ________.

ΔABC ~ ΔRTS

m ∠ S = 50°

ΔABC ≅ ΔRTS

m ∠ S = 60°

Answer:

Step-by-step explanation:

Rational funtion is a function f(x) in form of f(x)=p(x)/q(x). where p(x) and q(x) are polynomials and q(x)≠0.

Example: f(x)= (2x- 4)/(5x-6)

Rational equation is an equation involving rational expressions.

Example: [5/(x-3)] ≥ (2/x)

Rational inquality is an inqualit involving rational expressions.

Example: (2/x) - (3/2x) = 45

Step-by-step explanation:

Answer:

502.4 in²

Step-by-step explanation:

Area of a sphere = 4 πr²

Plastic beach balls are spherical in shape.

Hence, the Area of a sphere = 4πr²

Where r = radius = 2 inches

π = 3.14

Hence, the area of one spherical ball =

4 × 3.14 × 2²

= 50.24 square Inches

For 1 spherical ball, 50.24 square inches of plastic is needed to make it.

How many square inches of plastic does the company need to make 10 beach balls?

Therefore,

1 spherical ball = 50.24 in²

10 spherical balls = x

Cross Multiply

x = 10 × 50.24 in²

x = 502.4 in²

Therefore, 502.4 square inches of plastic is needed by the company to make 10 beach balls.

Answer:C. 13/6

Step-by-step explanation:

The slope is always rise over run. So when going from the coordinate (-5,-7) to the coordinate (1,6) we go up 13 then go to the right 6. And since we went up and to the right it is a positive slope.

Step-by-step explanation:

Answer:

265 miles per 6 hours

Step-by-step explanation:

Multiply 55 by 1, 2, 3, 4, 5 and so on, to get the speed per each of those hours.

55 x 2 = 110 miles per 2 hours

55 x 6 = 330 miles per 6 hours

55 x 7 = 385 miles per 7 hours

55 x 10 = 550 miles per 10 hours.

Answer choice b (265 miles per 6 hours) is not equivalent to 55mph.

I hope this helps!

Answer:

they are both divisible by 4

so you could write

4 (5 + 4)

Step-by-step explanation:

Answer:

First, I would find that the GCF of 20 and 16 is 4. Then, I would divide both 20 and 16 by 4. Last, I would use the distributive property to write the sum as 4(5 + 4).
