Answer:
27 and 29.
Step-by-step explanation:
Let the numbers be n and n + 2
2(n + 2) + n = 85
3n + 4 = 85
3n = 81
n = 27.
Answer:
Step-by-step explanation:
We have been given the equation:
And
Second equation can be rewritten as:
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
Now substitute in equation (1) we get:

Answer:
Assuming the similarity is that BC scales to EF, answer is
D. 1.5BC
Step-by-step explanation:
Because the triangles are smilar, AB/BC = DE/EF
If AB = 2BC
then DE = 2EF
but also DE = 3BC
so 2EF = 3BC
EF = 1.5BC
Answer: n=-36
Step-by-step explanation:
Let the number be n
2 fewer than a doubled number can be written as 2n-2
The number decrease by 38,can be written as n-38
Equate both
2n-2=n-38
Collect like terms
2n-n=-38+2
n=-36
The number is -36
