What is the answer for 3x-7y=4 solve for y

Answer:

20+10 is 30 5x6 is 30

Step-by-step explanation:

so just add numbers to find 30

Answer:

first number is 17 and second number is 13

Step-by-step explanation:

let the numbers are x and y

if their sum is 30 and difference is 4

then

x+y=30     --------------1equation

x-y=4          -----------2equation

add both the equations,

2x=34

x=17

then  

put the value of x in 1equation,

x+y=30

17+y=30

y=30-17

y=13

then,

first number is 17 and second number is 13

Answer:

(-3, -7)

Step-by-step explanation:

2x - y =  7                 multiply by -1  ⇔     -2x + y = -7

1x - y = 10                Do not change ⇔     1x -  y =  10  

                                                                     -x   = 3

                                                                      x = -3

Use the second equation to solve on y when x = -3

-1x - y = 10

-1(-3) - y = 10

 3 - y = 10

    -y = 10 - 3

    -y  = 7

     y = -7                         Solution:  (-3, -7)

Hi there!

Recall the formula for the area of a parallelogram:

A = b × h

b = base (mm)

h = height (mm)

Rearrange the equation to solve for the height:

A = bh

A/b = h

Plug in given values:

26.4/6 = 4.4 mm

Step-by-step explanation:

(1)

Since FE = FG the triangle is isosceles with ∠ E = ∠ G, then

∠ E = [tex]\frac{180-106}{2}[/tex] = [tex]\frac{74}{2}[/tex] = 37°

(2)

Since all 3 sides are congruent then triangle is equilateral with the 3 angles being congruent, 60° each , then

12y = 60 ( divide both sides by 12 )

y = 5

(3)

The 3 angles are congruent then triangle is equilateral with the 3 sides being congruent, then

KL = JL , that is

4t - 8 = 2t + 1 ( subtract 2t from both sides )

2t - 8 = 1 ( add 8 to both sides )

2t = 9 ( divide both sides by 2 )

t = 4.5

(4)

Given ∠ B = ∠ C then triangle is isosceles with 2 legs being congruent , that is

AB = AC

4x + 1 = 9 ( subtract 1 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Then

perimeter = AB + BC + AC = 4x + 1 + 2x + 3 + 9

                                            = 6x + 13

                                            = 6(2) + 13

                                            = 12 + 13

                                            = 25

Answer:

B.) the number of tents the army orders

Step-by-step explanation:

The word problem does not speak of any prices or tent sizes so it cant be A or C

Answer:

its B

Step-by-step explanation:

By applying the Pythagorean theorem, we will find that the length of the other leg of the right triangle is 40.7 yards.

If for right triangle we define A and B as the length of the two legs, and H as the length of the hypotenuse, the Pythagorean theorem says that:

A^2 + B^2 = H^2

Here we know that:

A = 14 yd

H = 43 yd

And we want to find the other leg, then we can replace that in the equation to get:

(14yd)^2 + B^2 = (43yd)^2

B = √( (43yd)^2 - (14yd)^2) = 40.7 yd

So the other leg length is 40.7 yards.

Step-by-step explanation:

So its negative x over 3, plus, 1 over 6

Answer:

A.) f(x)=1/3x + 1 and g(x)=1/3(6x)+1

Step-by-step explanation:

because firs you see the graph of intercepts or vertex.

see y-intercepts : our graph crosses though 1

the first choice crosses at 1 both f(x) & g(x)

the second choice crosses at 1 both f(x) & g(x)

the third choice crosses at -8 both f(x) & g(x) so this can't be answer.

the forth choice crosses at 1 both f(x) & g(x)

see x-intercept : f(x) crosses -3 and g(x) crosses at approximately -1/2

the first choice crosses at -3 at f(x) & - 1/2g(x)

the second choice crosses at -1/2 at f(x) & - 1/6g(x)

the third choice crosses at 8/3 at f(x) & 8/15g(x)

the forth choice crosses at -3 at f(x) & - 3/4(x)

the graph seems crosses at 1/2 at g(x).

so the answer if the first choice.

Answer:

Width = 27

Length = 9

*You might of switched width and length around please check*

Step-by-step explanation:

Width = 3x

Length = x

Perimeter Formula

2(3x+x) = 72

2(4x) = 72

8x = 72

x = 9

Since X was found, plug it in to find the width and length

3(9) = 27

x = 9

Answer:

5 5/8%, 5.6%, 5.51%, 5 1/2%, 5.099%

Step-by-step explanation:

5 5/8% reduces to 5.625…and 5.099% is the least because it isn’t even 5.1%…

So it goes—> 5.625%, 5.6%, 5.51%, 5 1/2% (5.50), and then 5.099%.

The descending order of interest rates is

5 5/8 % > 5.6 % > 5.51 % > 5 1/2 % > 5.099 %

What is Descending Order?

When numbers are arranged in descending order, they are done so from  largest to least . We must first compare the numbers before we may arrange them in any order. Compare first, then order. Numbers arranged in descending order: Determine how many digits each number has.

Given data ,

Let the total number of data be = 5

Now , the data can be represented in Set A = { 5.51% , 5 1/2% , 5 5/8% , 5.099% , 5.6% }

On simplifying the elements in the set , we get

5.51 % = 5.51 / 100

5 1/2 % = 5.5 / 100

5 5/8 % = 5.625 / 100

5.099 % = 5.099 / 100

5.6 % = 5.6 / 100

Now , the arranging the numbers in the descending order , we get

Hence , the interest rates in the descending order is

5 5/8 % > 5.6 % > 5.51 % > 5 1/2 % > 5.099 %
