What is the solution to the inequality?<br><br><br> -2x-4 less than or equal to 11
Rashid [163]

Answer:

x ≤  \frac{-15}{2}

Step-by-step explanation:

So first you would start by getting rid of the -4. To get rid of -4, you would need to + 4 on each side leaving you with -2x ≤ 15. Now you need to get rid of -2 from x so that would convert equation to x ≤  \frac{-15}{2}. Hoped it helped!

Clara has 8 coins worth 17¢. if the coins are all dimes and pennies, how many dimes and pennies does she have?
Sliva [168]
Let x = the number of dimes
Let y =  the number of pennies.

There are 8 coins, therefore
x + y = 8        (1)

The coins are worth 17 cents, therefore
10x + y = 17     (2)

Subtract equation (1) from equation (2).
10x + y - (x + y) = 17 - 8
9x = 9
x = 1

From (1), obtain
y = 8 -x = 8 - 1 = 7

Answer: 1 dime, 7 pennies.
