.
Step-by-step explanation:
If two equations
and
has infinitely many solutions, then
The given equations are
It is given that the above system of equations has infinitely many solutions. So,
Now,
and
and
and
So, a=1.5 and b=2.
Now,
Therefore,
.
Answer:
x=148
Step-by-step explanation:
First, find the missing angle by subtracting 100+48 from 180 (all of the angles in a triangle add up to 180). Then, subtract that from 180 (the angles are a linear pair, so they are supplementry, so they add up to 180) x+32=180.
x=148.

Answer:

Step-by-step explanation:
Because
is being multiplied by S, we can divide
from both sides of the equation. This will give us:
÷
But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of
÷
, you get:
×
When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.
By doing that, you get the fraction 
cannot be simplified any more, so S=
is your answer :)

Answer: - 60i - 14j
Step-by-step explanation:
- 18i + 16j - 42i - 30j = - 60i - 14j
Here, 2 1/4 r = 10
9/4 r = 10
r = 10*4 /9
r = 40 / 9
r = 4 4/9
In short, Your Answer would be Option C
Hope this helps!
