7 girls participated only in Karate.
21 + 8 = 29
29 + 7 = 36
36 + 6 = 43
Answer:
x = 26.5
Step-by-step explanation:
Step 1: Write equation
(t + 10.5) + 2t + 90 = 180
Step 2: Solve for <em>t</em>
<u>Combine like terms:</u> 3t + 100.5 = 180
<u>Subtract 100.5 on both sides:</u> 3t = 79.5
<u>Divide both sides by 3:</u> t = 26.5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
<u>Substitute:</u> (26.5 + 10.5) + 2(26.5) + 90 = 180
<u>Parenthesis:</u> 37 + 56 + 90 = 180
<u>Add:</u> 180 = 180
∴ x = 26.5
Answer:

Answer:
−2x−3+4c+6z+7+3c
=−2x+−3+4c+6z+7+3c
Combine Like Terms:
=−2x+−3+4c+6z+7+3c
=(4c+3c)+(−2x)+(6z)+(−3+7)
=7c+−2x+6z+4
