Emma buys a softball that is 70% off. If the original price is $30, how much does Emma pay?
Korvikt [17]

Answer:

$9

Explanation:

First, we need to find 70% of the original price of $30 using the following equation:

\text{ \$30 }\times70\text{ \% = \$30 }\times\frac{70}{100}=\text{ \$21}

It means that Emma pays $21 less than the original price. So, she pays:

$30 - $21 = $9

Therefore, the answer is $9

If LK=MK, LK=7x-10,KN=x+3, MN=9x-11 and KJ=28 find LJ
beks73 [17]
Suppose J, K, L, M, N are points on the same line.

MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14

Since LK = MK and LK = 7x - 10, then

7x - 10 = 8x - 14

8x - 7x = -10 + 14

x = 4

LJ = MK + KJ

MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18

LJ = 18 + 28 = 46
