Answer:
<h2>149 times.</h2>
Step-by-step explanation:
Let n be the number we are looking for.
The we have to solve this equation:
1999 - 7n = 1701 - 5n
⇔ 1999 - 1701 = 7n - 5n
⇔ 298 = 2 n
⇔ n = 298/2
⇔ n = 149
<u><em>Verification</em></u> :
1 999 - 7×149 = 956
1 701 - 5×149 = 956
the probability is 7/15
Step-by-step explanation:
because there are 7 girls and 8 boys
1) Given equation: x/5 + 9 = 11
2) Subtract from both sides of the equation 9 (use Subtraction Property of Equality):
x/5+9-9=11-9,
x/5=2.
3) Unknown variable is dividend, 5 is divisor and 2 is quotient. To find unknown dividend you should find the product of divisor and quotient or in another words use the Multiplication Property of Equality:
x=5·2,
x=10.
These three consecutive steps show you that correct choice is B.
Answer: correct choice is B.
