Answer:

Required Answer:-

Given:

5x - 3y = 2

3x - 2y = 4

To Find:

The values of x and y.

Solution:

We have,

→ 5x - 3y = 2 – (i)  

→ 3x - 2y = 4 – (ii)  

Multiplying equation (i) by 2, we get,  

→ 10x - 6y = 4 – (iii)

Multiplying equation (ii) by 3, we get,  

→ 9x - 6y = 12 – (iv)

Subtracting (iii) from (iv), we get,  

→ -x = 8  

→ x = -8  

Now, from (i),

→ 5 × (-8) - 3y = 2

→ -40 - 2 = 3y

→ -42 = 3y

→ y = -14  

So,  

→ (x, y) = (-8, -14)

Answer:

(x, y) = (-8, -14)

What is the approximate diameter of a sphere with a volume of 34 cm
Nutka1998 [239]

Answer:

<h3>The diameter is 4cm</h3>

Step-by-step explanation:

Volume of a sphere is

V =  \frac{4}{3} \pi {r}^{3}

Where r is the radius

diameter = radius × 2

To find the diameter we must first find the radius

Volume = 34cm³

That's

34 =  \frac{4}{3} \pi {r}^{3}  \\  \\ 34 \times 3 = 4\pi {r}^{3}  \\  \\ 102 = 4\pi {r}^{3}  \\  {r}^{3}   = \frac{102}{4} \pi \\  \\ r =  \sqrt[3]{ \frac{51}{2\pi}}  \\  \\ r = 2.01 \\  \\ r = 2.0 cm

Diameter = 2 × 2cm

<h3>= 4cm</h3>

Hope this helps you

Solve the equation for all values of x.<br> ∣4x + 4 ∣- 10 = 3x
sertanlavr [38]

Answer:

X = 6 , – 2

Step-by-step explanation:

| 4x +4| - 10 =3x

4x +4 - 10 = 3x

4x - 3x = 10 - 4

x = 6

_____o___o____

– (4x + 4) – 10 = 3x

– 4x – 4 – 10 = 3x

3x + 4x = – 4 – 10

7x = – 14

x = – 14/ 7

x = – 2

I hope I helped you^_^

ernie walks 1/6 mile in 1/12 hour when he walks along the river trail. How many miles per hour does Ernie walk when he hikes on
ohaa [14]

Answer:

2 miles

Step-by-step explanation:

distance=rate*time

d=rt

1/6=r*(1/12)

multiply both sides by 12

12(1/6)=r*(1/12)12

2=r*1

2=r

rate=2 miles per hour
