Answer:
to help you answer your question: 8+ 2x (x is the amount of times he goes swimming) for example if he were to go swimming 2 times--> 8+ (2)2 = $12
Answer:
1. A. Set the angle and arc measures equal.
2. B. major arc
3. B. Multiply the angle measure by 2.
4. A. minor arc
Step-by-step explanation:
1. If the intercepted arc is made from a central angle then angle of arc is equal to the central angle
2. 190 is a bigger angle than 170(angle of the remaining arc)
Therefore it is a major arc.
3.If the intercepted arc is made from a inscribed angle, then the angle of arc is double of the inscribed angle.
4. 115 < 245
Therefore it is a minor arc.

Answer:
i don't knpw good luck though
Step-by-step explanation:
It looks like your equations are
7M - 2t = -30
5t - 12M = 115
<u>Solving by substitution</u>
Solve either equation for one variable. For example,
7M - 2t = -30 ⇒ t = (7M + 30)/2
Substitute this into the other equation and solve for M.
5 × (7M + 30)/2 - 12M = 115
5 (7M + 30) - 24M = 230
35M + 150 - 24M = 230
11M = 80
M = 80/11
Now solve for t.
t = (7 × (80/11) + 30)/2
t = (560/11 + 30)/2
t = (890/11)/2
t = 445/11
<u>Solving by elimination</u>
Multiply both equations by an appropriate factor to make the coefficients of one of the variables sum to zero. For example,
7M - 2t = -30 ⇒ -10t + 35M = -150 … (multiply by 5)
5t - 12M = 115 ⇒ 10t - 24M = 230 … (multiply by 2)
Now combining the equations eliminates the t terms, and
(-10t + 35M) + (10t - 24M) = -150 + 230
11M = 80
M = 80/11
It follows that
7 × (80/11) - 2t = -30
560/11 - 2t = -30
2t = 890/11
t = 445/11
