Answer:
La anchura será de:
6 cm
Step-by-step explanation:
El formato original corresponde al 100%
Si se reduce un 60% quiere decir que:
100 - 60 = 40%
la reducción queda al 40%
entonces, por regla de tres:
15cm es al 100%
A cm es al 40%
A = 15*40/100
A = 6cm
Answer:
the answer is below frum ed
Step-by-step explanation:
y= -6
Y= -4
Y= -3
Y= 0
Answer:
This is just multiplying not simplify.
First thing you should do is reduce coefficients.
1st equation has all multiples of '2'. Divide by 2
---> x +3y = -6
2nd equation has multiples of 5. Divide by 5.
---> x - y = 2
Now elimination part is easier.
Eliminate 'x' variable by subtracting 2nd equation from 1st.
x + 3y = -6
-(x - y = 2)
----------------------
4y = -8
Solve for 'y'
4y = -8
y = (-8)/4 = -2
Substitute value for 'y' back into 2nd equation:
x - (-2) = 2
x + 2 = 2
x = 0
Solution to system is:
x=0, y =-2
Answer: 0.6
Step-by-step explanation: First, you want so seperate the equations in parenthesis to make solving the equation easier.
(-2/3x-9/8x )-(4/5x)-(1)
So (-2/3x-9/8x) equals -11/24x
And -11/24x-4/5x equals -151/120x
So -151/120x-1 ends up being 0.6.
