Answer:
A
Step-by-step explanation:
2(1)+ 1(2)+ 2(3)+2(4)+ 3(5)/ 10
= 2+2+6+8+15/10
= 33/10
= 3.3

Answer:
After 7 hours will be 1.95489493x10^12 viruses
Step-by-step explanation:
If the virus spread with 19% per hour after one hour it will increase 57 and continue in the 300+((300*0.19)^7) form, we just need to caculate the form
1) 2 x 7 x 2 = 28
28 + (3 x 7 x 5) = 54 cm cubed
The value of x in the linear equation 4(x + 5) = 9x + 4x − 34 is 6 after applying the property.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have linear equation in one variable:
4(x + 5) = 9x + 4x − 34
4x + 20 = 9x + 4x − 34 (Distributive Property)
4x + 20 -4x + 34= 9x + 4x − 34 -4x +34
(Subtraction Property of Equality and Addition Property of Equality)
54 = 9x
x = 6 (Division Property of Equality)
Thus, the value of x in the linear equation 4(x + 5) = 9x + 4x − 34 is 6 after applying the property.
