Find the lengths of the diagonals of rectangle JKLM if JL = 3x + 4 and KM

dlinn [17]

Answer:

Step-by-step explanation:

they intersect so their equal to each other so first you wanna find x.

3x + 4 = 4x - 1

-3x -3x

4 = x - 1

+1 +1

5 = x

then plug in x on each diagonals JL and KM.

JL= 3(5) + 4 = 19

KM = 4(5) - 1 = 19

SEE? THEY ARE EQUAL WHICH MEANS MY ANSWER IS CORRECT.:)

Two families visited an amusement park. The first family bought 2 hot dogs and 3 bottles of waters, which totaled $18. The secon

Ghella [55]

Answer:

$6.00

Step-by-step explanation:

To solve this problem, we have to construct two separate equations for each family, and then use any of the methods for solving simultaneous equations.

Let's consider h to represent the cost of 1 hot dog, and w to mean the cost of 1 water bottle.

• For the first family:

$2h + 3w = 18$

We can rearrange the equation to make w the subject:

⇒ $3w = 18 - 2h$

⇒ $w = \frac{18 - 2h}{3}$

• For the second family:

$4h + 2w = 28$

Since we have previously obtained an expression for w in terms of h, we can substitute that expression for w in the above equation, and then solve for h:

⇒ $4h + 2(\frac{18 - 2h}{3}) = 28$
