$\frac{1192}{7}$
Convert 149 to a fraction ( $\frac{149}{1}$ ).
To divide by a fraction, use the inverse or reciprocal (switch the numerator and denimoninator).
The reciprocal of $\frac{7}{8} [tex] is [tex] \frac{8}{7}$ .
So, multiply those two fractions together (149 x 8 = 1192) (1 x 7 = 7) to get $\frac{1192}{7}$

Vaselesa [24]

Answer:

C. y<3

Step-by-step explanation:

We are required to determine the solution set of the inequality

$15y-9$

Step 1: Add 9 to both sides

$15y-9+9$

Step 2: Divide both sides by 15

$15y \div 15$

The solution set of the given inequality is: y<3.

The correct option is C.

If you are solving y 2+2y=48 by completing the square, the next line would be

snow_tiger [21]

For this case we have the following equation:

$y ^ 2 + 2y = 48$

By completing squares we have:

Step 1:

Add $(\frac {b} {2}) ^ 2$ on both sides:

$y ^ 2 + 2y + 1 = 48 + 1$

Step 2:

We rewrite the equation:

$(y + 1) ^ 2 = 49$

Step 3:

We solve the equation:

$y = \pm \sqrt {49} -1\\y = \pm7-1$

Solutions:

$y = 6\\y = -8$

Answer:

the next line would be:

$y ^ 2 + 2y + 1 = 48 + 1$

Find the interest using the formula I = Prt Principal: $1800 Interest Rate: 6.5% Time: 30 months Interest =

Oliga [24]

I = P r t

I = (1800) (6.5÷100) (30÷12)

I = (1800) ( 0.065) (2.5)

I = 292.50$
