Answer:
a
Step-by-step explanation:
a. x=4, y=2
plug it in:
4+20=6 true
b. x=3, y=3
3+3=6
3=3+2
3=5 not equal
c. x=2,y=4
2+4=6
2=4+2
2=6 not true
d. x=6, y=4
6+4=6 not true
6=4+2
Answer:
x = 24.5
Step-by-step explanation:
the angles form a straight line, and a straight line equals to 180°
=> (5x + 8) + (3x - 24) = 180
=> 8x = 196
=> x = 24.5
Answer:
- x = 4
Step-by-step explanation:
First, we add 16 and 28
Now we have to solve for x
We know we have to do parenthesis first so
Then we divided both sides by 11
To find the Prime Factorisation of 84 we have to divide 84 by the smallest prime number which is 2
So
Since 42 is an even number we can still divide it by 2
So
Now we can divide 21 by the 2nd smallest prime number which is 3
So
So the prime factors of 84 would be or
