Answer:

z = 10

Step-by-step explanation:

Step 1: Make an expression

P = 2l + 2w

Step 2: Distribute

184 = 2(5z + 2) + 2(4z)

184 = (2 * 5z) + (2 * 2) + 8z

184 = 10z + 4 + 8z

184 = 18z + 4

Step 3: Subtract 4 from both sides

184 - 4 = 18z + 4 - 4

180 = 18z

Step 4: Divide both sides by 18

180 / 18 = 18z / 18

10 = z

Answer: z = 10

You have a set of cards labeled 1-10. Set A is drawing an even card. Set B is drawing a 8 or higher. What is the P ( A ∪ B ) ?

creativ13 [48]

set A = {2, 4, 6, 8, 10} (only even cards)

set B = {8, 9, 10} (8 or higher)

( A ∩ B ) means the numbers which are common in both sets .

They both have 8 & 10 in common.

So the answer is: P(A ∩ B) = {8,10}

harina [27]

Answer:

Proportion states that the two fractions or ratios are equal

As per the statement: Mrs. Hwang is taking her vehicle to the shop to have the gas tank expanded by 10 gallons. Now, it costs her $42.56 to fill the tank. Once the new tank is in, it will cost her $72.96

Let the tank size now be x

Since, the gas tank expanded by 10 gallons = x + 10

by definition of proportion ;

$\frac{x}{42.56}=\frac{x+10}{72.96}$
