I really need help with this math problem

Mathematics
1 answer:

Answer:

x ≥ -24

Step-by-step explanation:

To solve this inequality, we first need to review when to flip the inequality sign when solving.

<em>Flip the inequality sign whenever you multiply or divide an inequality by a negative number.</em>

<em />

Keeping this in mind, we can solve our inequality.

(x ÷ 4) ≥ -6

To get rid of the fraction on the left, multiply both sides by 4. (Note: we do not have to flip the inequality sign since we are multiplying by a positive number.)

(x ÷ 4) ≥ -6

x ≥ 4(-6)

x ≥ -24

~Hope this helps!~

X + y = 152,<br><br> 8.5x + 12y = 1,656<br><br> How many hats were sold?
Elodia [21]

Answer:

x = 48 and y = 104

Step-by-step explanation:

Given equations are:

x+y = 152\\8.5x+12y=1656

From equation 1:

x = 152-y

Putting the value of y in equation 2

8.5(152-y)+12y = 1656\\1292-8.5y+12y = 1656\\3.5y+1292 = 1656\\3.5y = 1656-1292\\3.5y = 364\\\frac{3.5y}{3.5} = \frac{364}{3.5}\\y = 104

Now we have to put the value of y in one of the equation to find the value of x

Putting y = 104 in the first equation

x+y = 152\\x+ 104 = 152\\x = 152-104\\x = 48

Hence,

The solution of the system of equations is x = 48 and y = 104

The value of variable which was assumed for number of hats, is the total number of hats.
