Answer:
x = 
of y
Step-by-step explanation:
Given:
15% of x equals 20% of y
So,
0.15x = 0.20y
so
x = 0.20 y / 0.15
x = 1.3333y
x = of y
I’m pretty sure the angle in 53 degrees
Answer:
The integers 1, 2, 3, 4, 5, 6, 7, 8, and 9 are always significant.
Zeros in between numbers are always significant.
Step-by-step explanation:
There are three rules by which the number of significant figures can be determined:
- The digits which are other than the zero are said to be significant figures.
- Any zero which is present between two significant figure is said to be significant.
- The zero which appears in the right of the decimal portion in the end is significant. The zero which comes after the decimal is not significant.
Answer:
(1, -8)
y= -8
x= 1
Step-by-step explanation:
7x-3y= 31
7x+y= -1
solve the equation
7x-3y=31
7x= -1-y
substitute the value of 7x into an equation
-1-y-3y=31
subtract -y to -3y
-1-4y=31
add both sides by 1
-4y=32
divide both sides by -4
y= -8
substitute the value of y into an equation
7x= -1-(-8)
distribute
7x=7
divide both sides by 7
x=1
(1, -8)
