J = K+6
K + J = 4K
<span>Replace J in the second equation </span>
K + (K + 6) = 4K
K + K + 6 = 4K
2K + 6 = 4K
Subtract 2K from each side
6 = 2K
Divide both sides by 2
K=3
<span>So, Keisha is 3 and therefore John is 9 because 3 + 6=9</span>
Using the formula (AB +BC) *BC = (DE +CD) *CD
fill i n what is known:
(17 + 4) *4 = (DE +6) *6
21*4 = (DE +6)*6
84 = (DE+6)*6
84/6 = DE+6
14 = DE +6
DE = 14-6
DE = 8
Answer:3
Step-by-step explanation:
y/2 is what we need. If y is 6. Then 6/2=3.
0.04 ones, I think.
since you're doing place value.
