The equation for the situation is 5x+6(0.95)=11.95

The solution to the equation is x=1.25

First, you must set up the equation.

5x+6(0.95)=11.95

Then, you must simplify the terms.

5x+5.7=11.95

Next, subtract 5.7 on both sides.

5x=6.25

Finally, divide 5 on both sides

x=1.25

One number is 8 more than the other. When the larger is divided by the smaller, the quotient is 7/5
Wewaii [24]

Answer:

<h3>          The numbers are 20 and 28</h3>

Step-by-step explanation:

x  - the other number  (the smaller one)

x+8  - 8 more than the other number (the larger number)

 

\dfrac{x+8}x=\dfrac75\\\\(x+8)\cdot5=x\cdot7\\\\5x+40=7x\\^{\quad-40\qquad-40}\\{}\quad5x = 7x-40\\^{\quad-7x\quad-7x}\\-2x=-40\\^{\div(-2)\quad\div(-2)}\\{}\ \ x=20\\\\x+8=28

saul85 [17]
He needs to learn >10 new plays, but has already learned 4. Therefore, the inequality is x+4>10, where x is the amount of new plays he must learn, 4 is the amount he has already learned and >10 (more than 10) is the amount of plays he needs to learn in total. 
x+4>10
x>6 is the solved inequality

user100 [1]

Answer:

2

Step-by-step explanation:

A midpoint divides a segment in two equal segments

DB = 3t

AB = 6t

BE = 4t

BC = 8t

8t + 6t + 7t + 6 = 48

21t = 42

t = 2
