The answer is 31/40
because first you got cane both of the fraction to the same denominator.
72/80 + 70/80
Add 72+70=142.
142/80 change it to an mixed number and it will be 1 31/40 in simplest form.
Answer:
The solution to this question is 39
Step-by-step explanation:
Given that :
√(3x+7)+2√(x-8)=0.
√(3x+7)=-2√(x-8) (i)
square of the equation (i)
Then
(√(3x+7))^2=(-2√(x-8))^2
we know that √a*√a=(√a)^2=a So,
(3x+7)=4(x-8)
3x+7=4x-32 //multiply by 4
32+7=4x-3x exchange the value.
39=1x
x=39.
4. 3(y + 4y) this is distributive property! Hope it helps. Btw can you please check out a question on my page? thanks!! <span />
Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = 
= 
= 
( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA = 
≈ 3.1 ft ( to the nearest tenth )
