Answer:

81.5+2.6=84.1

understand: we have to add the weight lost to her current weight to find the original weight.

plan: first we take 81.5 and add the weight lost to it 2.6

solution: 81.5+2.6=84.1

check: 84.1-2.6=81.5

Step-by-step explanation:

given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

13[tex]\sqrt{2}[/tex] - 5[tex]\sqrt{2}[/tex] < x < 13[tex]\sqrt{2}[/tex] + 5[tex]\sqrt{2}[/tex]

8[tex]\sqrt{2}[/tex] < x < 20[tex]\sqrt{2}[/tex] ( converting to decimal )

11.3 < x < 28.3

3 possible lengths for XZ are then values

11.5 cm , 13 cm , 18.5 cm

the other options are out with the range

Answer:

(-3,5)

Step-by-step explanation:

Hey there!

2/3x + 5 = 1

SUBTRACT 5 to BOTH SIDES

2/3x + 5 - 5 = 1 - 5

SIMPLIFY IT!
2/3x = 1 - 5

2/3x = -4

MULTIPLY 3/2 to BOTH SIDES

2/3x * 3/2 = -4 * 3/2

SIMPLIFY IT!

x = -4 * 3/2

x = -6

Therefore, your answer is: x = -6

Good luck on your assignment & enjoy your day!

Answer:

2/3x + 5=1

To solve for x, we must isolate it by administering inverse operations.

In this equation, we can see 2/3x is being added to 5.

We should discard the constants first.

The inverse operation of addition, is subtraction.

So we subtract 5 from both sides;

-5        -5

2/3x = -4

Now, we are left with a coefficient, so to get rid of the coefficient we utilize the inverse operation of multiplication, which is division.

Dividing by 2/3 is the same as multiplying by 3/2.

So multiply both sides by 3/2;

*3/2    *3/2

x = -4(3)/2

x = -12/2

x = -6

Answer:

Suppose the slope of a line were to decrease. Then it would get flatter. These conditions are true whether or not the slope was positive or negative to begin with. A higher positive slope means a steeper upward tilt to the line, while a smaller positive slope means a flatter upward tilt to the line.

For a decreasing function, the slope is negative. The output values decrease as the input values increase. A line with a negative slope slants downward from left to right as in (b). If the function is constant, the output values are the same for all input values so the slope is zero.

Answer:

The surface area increases by 4 times.

Step-by-step explanation:

square root of 288 = 16.970562.... (= 1 side)

1 side(x2) = 33.941125...... (= double of the side)

New area = new side squared

(33.94111....) squared =  1,152 (new area)

1,152/288 = 4    

new area is 4 times bigger

288 x4 = 1,152

Answer:

12%

Step-by-step explanation:

Read a book = 16%

Listen to music = 28%

We can read the question in different ways:

1.  The simple difference between the two is 12%

2.  Out of the sample, the two groups include:

    15 chose books

    35 chose music

    Within this sample of 50 teenagers,

           (15/50) or 30% chose books, and

            (35/50) or 70% chose music

             That makes a difference of 40%

I would chose the first interpretation, 12%  [Especially since 40% is not an option.]

When translating phrases into algebraic expressions, you need to identify keywords and phrases which specifically refer to a mathematical operation (addition, subtraction, multiplication, and division). Usually, you can write out the algebraic expression of the verbal description in the order that it is said

Answer:

7 & 5

Step-by-step explanation:

7+5=12
7-5=2
5-7=-2

Answer:

5 and 7

Step-by-step explanation:

5 + 7 = 12

5 - 7 = -2

Answer:

-12; 5

Step-by-step explanation:

x^2 + 7x - 60 = 0

D = b^2 - 4ac

D = 7 * 7 + 60 * 4 * 1 = 289

sqrt(D) = sqrt(289) = 17

x₁ = (-b - √D) / 2a = (-7 - 17) / 2 = -24 / 2 = -12

x₂ = (-b + √D) / 2a = (-7 + 17) / 2 = 10 / 2 = 5

Similar triangles may or may not have congruent sides lengths

From the properties of similar triangles, the side lengths of similar triangles may or may not be congruent, but the side lengths are always proportional.

Take for instance, an equilateral triangle has a dimension of 2cm by 2cm by 2cm

The similar triangles could have the following dimensions:

This is so because the triangles are proportional to the equilateral triangle

Answer:

the cost price of manufacturer = RS. 14.80

Step-by-step explanation:

the retailers profit = profit percent of sold amount

= 25% of 30.09

= 25/100 × 30.09

= 7.5225

here, the cost price of retailer =

sold amount- profit amount

or, CP = 30.09 - 7.5225

= 22.5675

now, profit of whole seller =

profit% of sold amount

or, 20% of SP

20/100 × 22.5675

= 4.5135

CP = SP - Profit

or, CP = 22.5675- 4.5135

CP = 18.054

now, profit of manufacturer = profit℅ of SP

= 18% of 18.054

= 18/100 × 18.054

= 3.24972

or, CP of manufacturer = SP - profit amount

= 18.054 - 3.24974

= 14.80428

Therefore, cost price of manufacturer = 14.80

ok so im really bad at explaining but ill try my best.

so since its asking you to fiure out how much he watched in total, youre going to have to add.

for one of the videos he watched 5/8 mins and for the other 1/8 mins.

5/8 + 1/8= 6/8

and since its asking for its simplest form youre gong to have to simplify it
