Caroline was thinking of a number. Caroline halves the number and gets 7.3. Form an equation with x from the information.

Damm [24]

Answer:

The equation is: $\frac{x}{2} = 7.3$

Step-by-step explanation:

Caroline was thinking of a number.

We are going to call this number x.

Caroline halves the number and gets 7.3.

To find half of a number, we multiply by 1/2. So

$\frac{1}{2} \times x = 7.3$

$\frac{x}{2} = 7.3$

JulsSmile [24]

Answer:

n = - 4

Step-by-step explanation:

note that 625 = $5^{4}$ , then

$5^{n}$ = $\frac{1}{5^{4} }$ = $5^{-4}$

Since the bases on both sides are equal, both 5 then equate the exponents

n = - 4

4x + y = 10<br> 7x + 2y = 17

Nezavi [6.7K]

Answer:

x = 3, y = - 2

Step-by-step explanation:

By substitution method,

4x + y = 10 -------> equation 1.

7x + 2y = 17 -------> equation 2.

From equation 1,

y = 10 - 4x ------> equation 3.

Substitute equation 3 in 2,

7x + 2 ( 10 - 4x ) = 17

7x + 20 - 8x = 17

7x - 8x = 17 - 20

- x = - 3

x = 3

Substitute x = 3 in equation 1,

4 ( 3 ) + y = 10

12 + y = 10

y = 10 - 12

y = - 2

Hence,

x = 3

y = - 2
