Answer:
Below.
Step-by-step explanation:
We can write an odd integer as 2x + 1 so consecutive odd digits would be 2x + 1 and 2x + 3, so the equation is:
2x + 1 + 2x + 3 = 156
4x + 4 = 156 can be used to solve for x and find the integers.
4x = 152
Dividing through by 4:
x = 152/4 = 38
So the 2 integers are 2(38) + 1 and 2(38) + 3
= 77 and 79.
Answer:
195
Step-by-step explanation:
1) formula of the required area is:
A=0.5*d₁*d₂;
2) according to the formula above the required area is:
A=0.5*(7.5*2)*(13*2)=0.5*15*26=195 (yd²).
A.
y = 20(1.15)^x.....parrots
y = 4x + 24.....snakes
B. after 10 yrs
y = 20(1.15^10)
y = 20(4.05)
y = 81 parrots
y = 4(10) + 24
y = 40 + 24
y = 64 snakes
C.
20(1.15)^x = 4x + 24
x = 6.63 years they will be the same
Add 8 to both sides then divide both sides by 3 and then your answer will be x = -2.3333333
