Answer:

x= 12 units.

Step-by-step explanation:

To solve this equation, we can find each half of the base using the Pythagorean theorem. We will use 'x' as denoting each HALF of the base:

45= 3²+x²

Subtracting from both sides will give us:

36= x²

x=6.

However, the base in this problem is '2x' because 'x' is HALF of the base.

2(6)= 12 units.

Two burgers and one hotdog cost $4.82. At the same price ,one burger and two hotdogs cost $3.70. How much does a hotdog cost?
STatiana [176]
Hello!

Let's use 'x' to represent the cost of the burger, and 'y' to represent the cost of the hotdog.

2x + y = 482

× + 2y = 370

2x + 47 = 740

-3y = -258

y = 86 cents

2x + 86 = 482

2x = 396

x = 198

A burger costs $1.98 and a hot dog costs $.86

I hope this didn't confuse you, I'm not very good at explaining!

pickupchik [31]

Answer:

<u>y = 6 x=8</u>

Step-by-step explanation:

(3х + 5y = 54)-2 times by -2

6х +4y = 72

-6х + -10y = -108 now combine the equations

6х + 4y = 72

-6y = -36 now divide

y = 6

Plug 6 in 6х +4 * 6 = 72

x=8

Anastasia is grocery shopping with her father and wonders how much shopping is left to do. "We already have 6 0 % 60%60, percent
Molodets [167]
If there are 12 items adding up to 60%, we want to know how many items more it will take to equal 100% So set up this equation 12/x = .6 then solve for x. x=12/.6 x = 20 now that we know the total you can subtract 12 from 20 and get 8, that is the number of items left on the list.
