Answer:
1.5
Step-by-step explanation:
k= y/x
y= 12-4.5 =7.5
x= 8-3 = 5
k = 7.5/5 = 1.5
Since both of the equations are equal to y...set them equal to each other.. So it will then be
x^2+3=x+5
-3 -3
x^2=x+2 ---> x^2-x-2
(x-2) (x+1)
x=2,-1
Answer:
324
Step-by-step explanation:
The shirt would be the same value because they are the same so
288÷3=96
Pi Shirt = 96
then work out the 3rd one to find out the balloons
98+ balloon + balloon= 226-96=130÷2= 65
Balloons = 65
then work out the 2nd one 195÷65=3
Pizza = 3
Then 4th one
25+1=26-3=29
Maccoroni = 29
Last question
96×3+65-29=324
Hello,
We know that
3×10^5= 3 EE 5
Change 80,000 to the scientific notation
8×10^4
Doing the same like 3×10^5, I can get 8 EE 4
Change 5000 to the scientific notation
5×10^3
Then it will appeared as 5 EE 3. Hope it help!
