Answer:
3Ax-6x = 15
3x(A-2)=15
If A were 2, the left side of the equation would be 0 and it wouldn't equal 15 no matter what the value of x is. So A is 2
Answer:
The x-intercept is 2
Step-by-step explanation:
So what you would do is you would distribute the 2 to x and 3 to get the equation y+2=2x+6. Then you would subtract 2 from both sides and get y=2x+4. And because your m is your x-intercept you get the answer: 2.
Answer:
Jake:y
grandma:6y
cousin:y+5
the sum of all their ages:8y+5
Step-by-step explanation:
given Jake:y
His grandma is 6 times his age
so
grandma:6y
His cousin is 5 years older than
him.
so
cousin:y+5
the sum of all their ages is
y+6y+y+5
8y+5
Answer:
L = 12
W = 20
Step-by-step explanation:
The perimeter of the rectangle is 64.
2L + 2W = 64
The length and width of a rectangle are in a 3:5 ratio.
3 + 5 = 8
64/8 = 8
2L = 8 * 3 = 24
L = 24/2 = 12
2W = 8 * 5 = 40
W = 40/2 = 20
