#22)
4(t - 8) + 20 = 5
Distribute the 4.

4t - 32 + 20 = 5
Combine like terms.

4t - 12 = 5
Add 12 to both sides.

4t = 17
Divide both sides by 4.

t = 4.25

#24)
17 = -5(3 + w) + 7
Distribute the -5.

17 = -15 - 5w + 7
Combine like terms.

17 = -8 - 5w
Add 8 to both sides.

25 = -5w
Divide both sides by -5.

w = -5

#26)
9 = -(r - 5) + 11
Distribute the -.

9 = -r + 5 + 11
Combine like terms.

9 = -r + 16
Subtract 16 from both sides.

-7 = -r
r = 7

Principal = 5300=5300 rupees

PSYCHO15rus [73]

Answer:

Using the formula:

$A=P+I$

where

A is the total amount

P is the principal

I is the Simple Interest

As per the statement:

Principal(P) = 5300 rupees.

rate of interest(r) = 6.5% = 0.065

Total amount(A) = 6678 rupees.

Then using above formula we have;

$6678 = 5300+I$

Subtract 5300 both sides we get;

$1378 = I$

$I = \$1378$

We have to find the time period.

Using formula of Simple interest:

$I = Prt$

where r is the rate of interest (in decimal)

here, r = 6.5% = 0.065

Substitute the given values top find t:

$1378 = 5300 \cdot 0.065 \cdot t$

⇒ $1378 = 344.5t$

Divide both sides by 344.5 we have;

$4 = t$

Therefore, the time period t in years is 4 years
