Elimination method<br> x+4y=1<br> -3x-5y=-10
nevsk [136]

Answer:

x = 5 and y = 1 is the answer.

Step-by-step explanation:

(-5)(x+4y=1)

(-4)(-3x-5y=-10)

-5x + -20y = -5

12x + 20y = 40

———————

7x + 0 = 35

7x= 35

7x/7 = 35/7

x = 5

subtitution:

x= 5

x + 4y = 1

5 + 4y = 1

4y = 1 - 5

4y = 4

4y/4 = 4/4

y = 1

Translate the sentence into an equation, then solve the
Oduvanchick [21]

Answer:

The equation is: \frac{x-7}{5} = 13 and the number is 72.

Step-by-step explanation:

We have to use mathematical notation to convert the given statement into an equation. As we don't know the exact value of number, we have to use a variable in place of the number.

Let x be the required number then

"A number decreased by 7"

x-7

"and then  divided by 5"

\frac{x-7}{5}

" is 13."

\frac{x-7}{5} = 13

For solving, multiplying both sides of equation by "5"

\frac{x-7}{5} * 5 = 13*5\\x-7 = 65

Adding 7 on both sides of equation

x-7+7 = 65+7\\x = 72

Hence,

The equation is: \frac{x-7}{5} = 13 and the number is 72.

The shorter leg of a right triangle is 7cm shorter than the longer leg. The hypotenuse is 7cm longer then the linger leg. What i
Gelneren [198K]

The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.

Step-by-step explanation:

Let,

The longer leg = x

The shorter leg = x-7

Hypotenuse = x+7

Using Pythagoras theorem;

a^2+b^2=c^2\\(x-7)^2+(x)^2=(x+7)^2\\x^2-14x+49+x^2=x^2+14x+49\\2x^2-14x+49-x^2-14x-49=0\\x^2-28x=0\\x(x-28)=0\\

Either,

x= 0

Or,

x-28=0      =>x=28

As length cannot be zero, therefore,

Longer side = 28cm

Shorter side = x-7 = 28-7 = 21cm

Hypotenuse = x+7 = 28+7 = 35cm

The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
