Answer:
23
Step-by-step explanation:
Ā means the average
So it means the average of 64 gave their speech which should be 64/2 = 32
So 32 gave their speeches yesterday,
7 gave today
Total number that has given is
32 + 7 = 39
Therefore the number remaining are
62 - 39 = 23
The number of infected people will reach 568 in approximately 4 weeks
<h3>Linear equation and function</h3>
Exponential equations are inverse of logarithmic equation and are represented by the equation below:
y = ab^x
where
a is the base value and x is the exponent
Given the equation that shows the number of infected people from an outbreak of the measles as:
y = 4(6)^t
If the number of infected people reach 568, hence;
568 = 4(6)^t
568/4 = 4(6)^t/4
6^t = 568/4
6^t = 142
Take the natural logarithm of both sides
ln(6^t) = ln142
t = ln142/ln6
t = 4.37
Hence the number of infected people will reach 568 in approximately 4 weeks

X + y = 22
x = 3y + 2
3y + 2 + y = 22
4y + 2 = 22
4y = 22 - 2
4y = 20
y = 20/4
y = 5
x = 3y + 2 = 3(5) + 2 = 15 + 2 = 17
ur numbers are 5 and 17
