-5x < 10

Divide the two sides by -1.
If an inequality form is divided by negative number, the sign will change.
-5x < 10
-5x/-1 > 10/-1
5x > -10

Then divide the two sides by 5
5x/5 > -10/5
x > -2

The answer is -2

Elias was given a lock for his school locker. The lock contains numbers between

daser333 [38]

Answer:

34,220

Step-by-step explanation:

Because order doesn't matter, but the numbers can't be repeated, we need to find the number of combinations where 3 individual numbers can be chosen out of 60 possible numbers using the binomial coefficient:

$\binom{n}{k}=\frac{n!}{k!(n-k)!}\\ \\\binom{60}{3}=\frac{60!}{3!(60-3)!}\\\\\binom{60}{3}=\frac{60!}{3!(57)!}\\\\\binom{60}{3}=\frac{60*59*58}{3*2*1}\\ \\\binom{60}{3}=34220$

Thus, Elias can make 34,220 unique 3-number codes given 60 different numbers.

"Bert has half as much money as Ernie. If Ernie loses $225 and Bert earns $675, Bert will have twice as much money as Ernie. How

Rzqust [24]

Answer: Ernie has $750 and Bert has $\dfrac{750}{2}=\$375$

Step-by-step explanation:

Let the amount that Ernie has be 'x'.

Let the amount that Bert has be $\dfrac{x}{2}$

Amount lost by Ernie = $225

Amount gained by Bert = $675

According to question, we get that

$2(x-225)=\dfrac{x}{2}+675\\\\2x-450=\dfrac{x}{2}+675\\\\2x-\dfrac{x}{2}=675+450\\\\\dfrac{4x-x}{2}=1125\\\\\dfrac{3x}{2}=1125\\\\x=\dfrac{1125\times 2}{3}\\\\x=\$750$
