10=a/2 + 7
First subtract 7 from both sides
3=a/2
Next multiple 2 on both sides, so that a is by itself
3(2)=a
A=6
Answer:
4/5
Step-by-step explanation:
Simplify the following:
7 + 1/5 - (6 + 2/5)
Put 6 + 2/5 over the common denominator 5. 6 + 2/5 = (5×6)/5 + 2/5:
7 + 1/5 - (5×6)/5 + 2/5
5×6 = 30:
7 + 1/5 - (30/5 + 2/5)
30/5 + 2/5 = (30 + 2)/5:
7 + 1/5 - (30 + 2)/5
30 + 2 = 32:
7 + 1/5 - 32/5
Put 7 + 1/5 - 32/5 over the common denominator 5. 7 + 1/5 - 32/5 = (5×7)/5 + 1/5 - 32/5:
(5×7)/5 + 1/5 - 32/5
5×7 = 35:
35/5 + 1/5 - 32/5
35/5 + 1/5 - 32/5 = (35 + 1 - 32)/5:
(35 + 1 - 32)/5
35 + 1 = 36:
(36 - 32)/5

Step-by-step explanation:
To solve this, you would set up the equation to find the arithmetic mean of the data. This equation is (53+83+67+73+x)/5=70, where x=the score of the fifth exam. First, you combine the constants to get (276+x)/5=70. Then, multiply both sides by 5 to get rid of the denominator, to give you 276+x=350. Then subtract 276 from each side to get x=74. So, Thanh needs to score a 74 on his last exam to get a 70 in the class.
