When we have exponents like such (x^-6)^-2 , the numbers are multiplying, so we have x^12, then we take that value and, because it is dividing with the same base, we substract the numbers, so x^12-(-4) = x^16.
154 divided by 2
Answer = x = 77
Answer:
Total number of tables of first type = 23.
Total number of tables of second type = 7
Step-by-step explanation:
It is given that there are 30 tables in total and there are two types of tables.
Let's call the two seat tables, the first type as x and the second type as y.
∴ x + y = 30 ......(1)
Also a total number of 81 people are seated. Therefore, 2x number of people would be seated on the the first type and 5y on the second type. Hence the equation becomes:
2x + 5y = 81 .....(2)
To solve (1) & (2) Multiply (1) by 2 and subtract, we get:
y = 7
Substituting y = 7 in (1), we get x = 23.
∴ The number of tables of first kind = 23
The number of tables of second kind = 7
Answer:
<h2>Jake's strand represents 4 times David's strand.</h2>
Step-by-step explanation:
To find the ratio between these diameters, we just need to divide them
and 
If we divide
Therefore, Jake's strand represents 4 times David's strand.
Let x= Kiera, y=Larry, z=Gita
"Kiera picked twice as many pounds as Larry" x=2y
"Kiera picked 3 times as many pounds as Gita" x=3z
"Total weight is 8360" x+y+z=8360
substitute in values
x+y+z=8360
3z+1.5z+z=8360
z=1520
x= 3*1520=4560
y=4560/2=2280
