Answer:
equation: x+3=y
Step-by-step explanation:
If the dog is 3 years older, then you take the cat + 3 to = the dogs age
Answer:
20%
Step-by-step explanation:
We can start by looking at it as a ratio, so 4 divided by 20 and 4/20 = 0.2, so that would be 20% viewing 1=100%.
Another way is
20 here is 100%, and for 20 to equal 100, we have to multiply it by 5. To balance it out, multiply the top by 5 as well, and 4 * 5 =20. Therefore, 4/20 = 20%
Subtract the two numbers to find the difference:
200-196 =4
Divide the difference by the estimated number:
4/200 = 0.02
Multiply by 100 to change to percent:
0.02 x 100 = 2%
The answer is 2%
Answer:
(4,2)
Step-by-step explanation:
-3x+5y=-2
3x+7y=26
I will add the two equations to eliminate x
-3x+5y=-2
3x+7y=26
---------------------
0x + 12y = 24
Divide by 12
12y/12 = 24/12
y =2
Now find x
3x+7y =26
3x+7*2 =26
3x+14= 26
Subtract 14 from each side
3x+14-14 =26-14
3x= 12
Divide by 3
3x/3 =12/3
x=4
X * Y * 9 = 432
Divide 9 from both sides
X * Y = 48
That gives you a variety of answers
1 * 48
2 * 24
4 * 12
6 * 8
