The sides of a triangle are in the extended ratio of 3 : 4:10. If the length of the
shortest side is 9 in., what is the perimeter of the triangle?

Answer:

The answer is 3x + 8.

Step-by-step explanation:

1) Collect like terms.

Answer:

Height of the triangle = 10 cm

Step-by-step explanation:

Given:

Dimensions of rectangle = 3 cm , 10 cm

Base of triangle = 6 cm

Find:

Height of the triangle

Computation:

Given that area of rectangle is equal to area of triangle

So,

(l x b) = (1/2)(b)(h)

(3 x 10) = (1/2)(6)(h)

30 = 3(h)

h = 10

Height of the triangle = 10 cm

Answer: 5

Step-by-step explanation:

Answer:

x = 3

y = 8

Step-by-step explanation:

ok we will substitute

y = x + 5

into the second equation

4x + y = 20

4x + (x + 5) = 20

5x + 5 = 20

5x = 15

x = 3

y = x + 5 = 3 + 5 = 8

Answer:

4(3)+y=20

Step-by-step explanation:

4*3=12

Y= 3+5

3+5=8

12+8=20

Step-by-step explanation:

Answer:

x=y+-5/2

Step-by-step explanation:

Let's solve for x.

2x+10=2y+5

Step 1: Add -10 to both sides.

2x+10+−10=2y+5+−10

2x=2y−5

Step 2: Divide both sides by 2.

2x

2

=

Answer:

x > -7

Step-by-step explanation:

Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

First, subtract 15 from both sides:

-8x + 15 (-15) < 71 (-15)

-8x < 71 - 15

-8x < 56

Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:

(-8x)/-8 < (56)/-8

x < (56)/-8

x > -7

x > -7 is your answer.

~

Answer:

Any number greater than but excluding -7.

Step-by-step explanation:

-8x + 15 < 71

-8x < 71 - 15

-8x < 56

56 divided by -8 = -7

So, that means anything greater than -7 would result in a lower number than 71.

Answer:

D. Neither Ryan nor Addy

Step-by-step explanation:

Square:

A square is a quadrilateral that has equal sides and all angles equal to 90 degrees.

Rectangle:

A rectangles is a quadrilateral that has equal or unequal  sides and all angles equal to 90 degrees. All rectangles are not squares.

Rhombus:

A rhombus is a quadrilateral that has equal sides and all angles may or may not be  equal to 90 degrees. All squares are rhombus. But all rhombus are not squares.

As both Ryan and Addy have missed out one property of square therefore both of them are incorrect.

Answer:

x = 124°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x = 180° - (32 + 24)° = 180° - 56° = 124°

Answer:

x=-2,y=10

Step-by-step explanation:

y=8-x.............equation 1

4-y=-5..........equation 2

Now,

putting the value of y in equation 2,

4-(8-x)=-5

4-8+x=-5

-3+x=-5

x=-5+3

x=-2

Then,

putting the value of x in equation 1

y=8+2

y=10

b = -3

c = -2

x = 1.175

x = -0.425

Answer:

1mm:3cm

Step-by-step explanation:

8mm:24cm

----------------     = 2mm:6cm

       4

2mm:6cm  divided by 2 equals 1mm: 3cm

The required simplest form of 8mm; 24cm is 1mm; 3cm.

We have to determine, the simplest form of 8 mm: 24 cm.

To obtain the simplest form of the equation calculation must be done in a single unit following all the steps given below.

The ratio is just a way to compare two quantities while the proportion is an equation that shows that two ratios are equivalent.

Here, 8 mm: 24 cm.

Therefore,

[tex]8mm \ ; 24cm[/tex]

Divided by 8 both sides,

[tex]= \dfrac{8mm}{24cm}\\\\= \dfrac{1mm}{3cm}[/tex]

Hence, The required simplest form of 8mm; 24cm is 1mm; 3cm.

Answer:

Step-by-step explanation:

if 10 pgs = 120 mins

then 15 pgs = 15 × 120÷10

                 =1800÷10

                = 180 mins

if 60 min = 1 hr

then 180 min = 180×1÷60

Answer:

Kelly is 19; Brandon is 13

Step-by-step explanation:

k + b = 32.  Also:  k = b + 6.

Substituting b + 6 for k in the first equation, we get b + 6 + b = 32, or

2b = 26.  Then b must be 13, and k must be 13 + 6, or 19.

Kelly is 19; Brandon is 13.

Answer:

Brandon is 13, Kelly is 19.

Step-by-step explanation:

Let's set up our equations.

Kelly and Brandon have a combined age of 32.

K + B = 32

They have an age difference of 6. Kelly is older.

K - B = 6

Let's shift the equation around a little.

K - B = 6

Add B to both sides.

K = B + 6

Now let's plug K into our first equation.

K + B = 32

(B + 6) + B = 32

Combine like terms.

2B + 6 = 32

2B = 26

Divide both sides by 2.

B = 13

Now that we know Brandon is 13, we can find Kelly's age.

K + B = 32

K + 13 = 32

K = 19

Kelly is 19.

Hope this helps!
