Answer:  x = 6

Step-by-step explanation:

The perimeter of the isosceles triangle = 2 leg + base

Since the perimeter = 60

then 60 = 2(5x - 3) + x

       60 = 10x - 6 + x

 60 + 6 = 11x

         6 = x

Step-by-step explanation:

STEP 1: Simplify 8/5

equation at end-                                                                                                           8 (7 - 3t) -  (5 • ((0 -  (— • t)) +  5)) 5          

STEP 2:          2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  5  as the denominator :

      5     5 • 5

   5 =  —  =  —————

        1       5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

\2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-8t + 5 • 5     25 - 8t

———————————  =  ———————

EQUATION AT END:  (25 - 8t)

 (7 - 3t) -  (5 • —————————)

                      5    

STEP 3:  (7 - 3t) -  (25 - 8t)

Answer

[tex]1)8(m -5 ) = 48 \\ 8m - 40 = 48 \\ 8m = 48 + 40 \\ 8m = 88 \\ \frac{8m}{8} = \frac{88}{8} \\ m = 11[/tex]

[tex]2)x + 7 = 13 \\ x = 13 - 7 \\ x = 6[/tex]

Hope this helps you.

Let me know if you have any other questions :-):-)

Answer:

m=11, x=6, h=5 2/3

Step-by-step explanation:

8(m-5) = 48

m-5 = 48/8 = 6

m = 6+5 = 11

m = 11

x + 7 = 13

x = 13-7 = 6

x = 6

3h - 5 = 12

3h = 12 + 5 = 17

h = 17/3 = 5 2/3 or 5.67

Answer:

JL = √38.

a = 1 and b = 38.

Step-by-step explanation:

Using Pythagoras:

(JL)^2 = (√8)^2 + (√30)^2

(JL)^2 = 8 + 30 = 38.

JL = √38.

A is correct

Step-by-step explanation:

Answer:  y = -(4/3)x + 1

Step-by-step explanation:

Let's start with finding an equation of a straight line (y=mx+b) that goes through points (-2,1) and (6,7).

The slope of a line, m, is the change in y for the change in x, or Rise/Run.

This is derived from the two points.

Rise (7-1) = 6

Run (6 - (-2)) = 8

Rise/Run = 6/8 or 3/4

The line is therefore y = (3/4)x + b

Find b by using one of the two points.  I'll use (-2,1), but the other would also work.

y = (3/4)x + b

1 = (3/4)(-2) + b

1 = -(6/4) + b

b = 10/4

The line becomes y = (3/4)x + 10/4

--------

A line perpendicular to this will have a slope that is the negative inverse of the original line.  The negative inverse of (3/4) is -(4/3).

The perpendicular line will be:

y = -(4/3)x + b

Use point (-6,9) to find b:

y = -(4/3)x + b

9 = -(4/3)*(-6) + b

9 = (24/3) + b

b = (27/3 - 24/3) = 3/3 = 1

The line is y = -(4/3)x + 1

Answer:

1) x + 4 = 11

Subtract 4 on both sides, to get x = 7 .

2) x + 3 = 24

Subtract 3 on both sides, to get x = 21 .

3) 4x = 12

Divide 4 on both sides, to get x = 3 .

4) 5x + 3 = 33

First subtract 3 on both sides to get

5x = 30, now divide 5 on both sides, to

get x = 6 .

5) 8x + 5 = 3x + 20

First subtract 5 from 20 in order to

move it, now you have 8x = 3x + 15 .

Next subtract 3x from 8x in order to

move it, now you have 5x = 15 . Lastly

divide 5 on both sides, to get x = 3 .

1) 1/2 x = 4

Multiply both sides by 2, to get 1x = 8,

or x = 8 .

2) 4/3 x = 4

Multiply both sides by 3, to get 4x = 12 .

Next divide 4 on both sides to get

x = 3 .

3) 2x + (-4) = 8

Add 4 on both sides, to get 2x = 12 .

Next divide 2 on both sides to get

x = 6 .

4) 1/3 x + 1/2 x = 20

First multiply the denominators to get a

common denominator of 6 and then

add 3 and 2, to get the numerator. Now

you have 5/6 x = 20 . Next multiply 6

on both sides to get 5x = 120 . Lastly

divide 5 on both sides to get x = 24 .

5) 1/3 x = 1/5 x + 10

First multiply the denominator to get a

common denominator of 15 and then

subtract 3 from 5 to get the numerator.

Now you have 2/15 x = 10 . Next

multiply 15 on both sides to get

2x = 150. Lastly divide 2 on both sides

to get x = 75 .

Hope this helped :)

Answer:

For to the be the studip

Step-by-step explanation:

Yes, give man brainiest

The values of the letters in coordinates (a, b) and (c,d) are;

a = -4

b = -6

c = 2

d = 6

We are given two equations;

-6x + 3y = 6  ---(eq 1)

x² + y = 10 ---(eq 2)

Let us make y the subject in eq 2 to get;

y = 10 - x²  --(eq 3)

-6x + 3(10 - x²) = 6

expanding further gives;

-6x + 30 - 3x² = 6

rearranging gives;

3x² + 6x - 24 = 0

Using online quadratic equation solver, we have;

x = -4 and x = 2

Putting x = -4 into eq 3 gives;

y = 10 - (-4)²

y = 10 - 16

y = -6

Putting x = 2 into eq 3 gives;

y = 10 - (2)²

y = 10 - 4

y = 6

Comparing with (a, b) and (c,d), we have;

a = -4

b = -6

c = 2

d = 6

Answer:

(0,-1); (0,-2); (2,0); (2,-2)

Step-by-step explanation:

when rotating 180 degrees all the points have their coordinate sign's flipped.

so the points go from:

(0,1) --> (0,-1)

(0,2) --> (0,-2)

(-2,0) --> (2,0)

(-2,2) --> (2,-2)

so your new shape will have the points (0,-1); (0,-2); (2,0); (2,-2)

Answer:

1000

Step-by-step explanation:

Answer: 1000

Step-by-step explanation:

Answer:$25.00

Step-by-step explanation:

Net Amount (excluding tax) $25.00

Tax (10.0%) $2.50

Gross Amount (including tax) $27.50

in short 10% tax of $25.00 is $27.50.

The required cost of the sweatshirt before tax s given as $24.50.

The percentage is the ratio of the compositions of matter to the overall composition of matter multiplied by 100.

Here,
Roger paid $27.50 for a sweatshirt. This amount includes a sales tax of 10%.
Cost of the sweatshirt before tax = 27.50 - 10% of 27.50
                                                   = 27.50 - 0.1× 27.50
                                                  = $24.50

Thus, the required cost of the sweatshirt before tax s given as $24.50.

Answer:5 rational numbers are 19/27, 20/27, 21/27, 22/27, 23/27

Step-by-step explanation:

Answer:

proof: answer is 2/13

1 / 6.5 = m

m = 0.153846154

10/65 = m

m = 2/13

2/13 = m

m = 0.153846154

Therefore we could show multiplication proof

m = 10/65  =   m = 2/13

2 x 5 = 10

13 x 5 = 65

Step-by-step explanation:

See attached graph of y = 6.5x+75.5

plotting the graph

1. Mark y intercept at 75.5 as given in the equation

2. find the slope to whole numbers

m =  10 across / 65 across = 6.5 slope

Mapping Pythagoras   10^2 +65^2 = c^2

sqrt 100 + sqrt 4225 = c^2

c^2 = sqrt 4225 = 65.7647322 = 65.8

0.7647322 / 65 = 0.0117651108 = 100th

65 + 0.0117651108 = 65.011765.....

Therefore 10 across / 65.0118  down

or 10 across  / 65 down is another way to graph, as seen on graph.

m = 10/65  =   m = 2/13

2 x 5 = 10

13 x 5 = 65

Answer:

10

Step-by-step explanation:

This can be calculated correctly using BIDMAS. This stands for Brackets, Indices, Multiply, Divide, Add, Subtract. Using BIDMAS will allow us to know what order to answer the question in.

In BIDMAS, Divide comes before Add, so we know to do this part first. So we do 8 divided by 2 which is 4.

The next part of our question is to add 6, so we do 6+4=10. So, 10 is the final answer.
