The value of x is 4 which balances the given equation
Answer:
y + 15/2x - 7
Step-by-step explanation:
The sequence is to add 2 each time
8-3=5
15-8=7
24-15=9
35-24=11
therefore the next numner would be =13 so 35+13= 48
bc.....
48-35= 13
basically as the number gets bigger the added number gains 2pts each time
hope this helps
Answer:
figure 3: 17 cubes.
figure 4: 21 cubes.
figure 5: 25 cubes.
Step-by-step explanation:
Let the nth figure be represented by f(n).
also we are given f(n+1)=f(n)+4.
The number of cubes used in figure 1 i.e. f(1) is 9.
number of cubes used in figure 2 i.e. f(2) is 13
Now we have to find the number of cube used in figure 3, figure 4 and figure 5.
number of cubes in figure 3 i.e. f(3)=f(2)+4=13+4=17.
number of cubes in figure 4 i.e. f(4)=f(3)+4=17+4=21.
number of cubes in figure 5 i.e. f(5)=f(4)+4=21+4=25.
