Answer:

6x-y=2

y-2=6x-4

Since x is on the right side of the equation, switch the sides so it is on the left side of the

A combo meal and a salad cost $12

lubasha [3.4K]

Answer:

The cost of a combo meal is $8 and a salad is $4.

Step-by-step explanation:

You have to form simultaneous equations with the given informations. Let combo meal be m and salad is s :

$m + s = 12 - - - (1)$

$2m + s = 20 - - - (2)$

Next, you have to solve these equations :

$(2) - (1)$

$2m + s - m - s = 20 - 12$

$m = 8$

$sub \: \: m = 8 \: \: into \: \: (1)$

$(1)⇒$

$8 + s = 12$

$s = 4$

A building casts a shadow that is 15 meters in length The distance from the top of the building to the top of the shadow is 25 m

Ber [7]

Answer:

20 meters

Step-by-step explanation:

The shadow of the building will look like a right triangle. In this problem, the hypotenuse of the triangle is 25 meters, and one of the sides is 15 meters. What we are trying to find is the length of the other side.

We can do this by using pythagoreans theorem.

$15^2 + x^2 = 25^2\\225 + x^2 = 625\\x^2 = 400\\x = 20$

So, the last side (or the height of the building) is 20 meters.
