Answer:
30
Step-by-step explanation:
Equation y = 3x + 210
if y = 10x
10x = 3x + 210
or, 10x - 3x = 3x + 210 - 3x
or, 7x = 210
or, x = 210 ÷ 7
or, x = 30
Answer:
its a acute angle........
The answer is A. To add fractions, the denominator has to be the same. What number do 9 and 3 share when multiplying ? It is 9.
So multiply 2/3 by 3/3 to get 6/9. And 1/9 by 1/1 to get 1/9. Now add 6/9 with 1/9 which is 7/9
Now add 7/9 with 5/18. 9 and 18 share 18. Multiply 7/9 by 2/2 which is 14/9. Add 14/9 to 5/18 which is 19/18
Answer:

#2 is 3.1 x 10^6
#3 is 5.3 x 10^-6
#4 is 4.2 x 10^-1
Step-by-step explanation:
You just need to multiply/divide the decimals, didn't even need the exponents
Answer:
The correct option is Option C
Step-by-step explanation:
We are given the lines: 
The lines are perpendicular if they have opposite slopes i,e 
In line 1 the slope is 
(Comparing with slope-intercept form 
we get the value of m=-4/5)
In line 2 the slope is 
(Comparing with slope-intercept form we get the value of m=-5/4)
The opposite reciprocal of -4/5 is 5/4
So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.
If the lines are parallel there slope must be same. Hence lines are not parallel as well.
So, The correct option is Option C
