R=2K which equals 2R=4K
4(R=K+8) or 4R=4K+32
Subtract first equation from second equation.
2R=32 so R=16
Plug into first equation
16=2K so K=8
Now plug both into second equation to check
4R-4K=4(R-K)=4(8)=32 it works
So Roberto is 16 and Katie is 8
(In 4 years R would be 20 and K would be 12 which has a difference of 8)
Answer:
The figure shows the boundary junction temperatures (in degrees Fahrenheit) of a thin metal plate. The temperature T at any interior junction can be approximated by the mean of the temperatures at each of the four surrounding junctions. Approximate T1, T2, T3 and T4 to the nearest tenth decimal place. 55° 55° T2 27° 27 T TA 27° 27° 3° 3°
Your slope is wrong! Your slope is going to be 3/2, or C for the first problem. Your y intercept is wrong! Your Y- intercept is actually (0, -1.3) or B for the second problem.
Your equation is going to be
y= 3/2x-1.3
Answer:
this is false. that would be the formula to find the volume
Step-by-step explanation:
It would be d , because the lowest number which is your (min) is 72 the highest number which is your (max) is 93 . Your median would be 85 because you would add 84 & 86 and in result you would get 170 then you would divide by 2 and get 85 . Your Q1 would be 76 and your Q3 would be 91 , there is 10 numbers in total separate them (72,74,76,83,84) and (86,89,91,92,93) then find the middle number in each
Hope this helps !
