Solve the equation systems or set the values x = 1.8 and y = -0.9 on the equation and check the equality.
A.
6x - 5y = 15
L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3
R = 15
L ≈ R
x + 2y = 0
L = 1.8 + 2(-0.9) = 1.8 - 1.8 = 0
L = R
B.
4x + 5y = 8
L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7
R = 8
L ≠ R
C.
x - 2y = 4
L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6
R = 4
L ≈ R
4x + 5y = 8
L = 4(1.8) + 5(-0.9) = 7.2 - 4.5 = 2.7
R = 8
L ≠ R
D.
6x - 5y = 15
L = 6(1.8) - 5(-0.9) = 10.8 + 4.5 = 15.3
R = 15
L ≈ R
x - 2y = 4
L = 1.8 - 2(-0.9) = 1.8 + 1.8 = 3.6
R = 4
L ≈ R
We have two probability solutions: A and D.
But I think, Your answer is A.
I’m not going to say the answer but just\ multiply those fractions together to get the answer
Answer:
-11
Step-by-step explanation:
Given
Use properties:
Thus,
Ok so
x - the smallest
The other 4 are : x+1, x+2, x+3, x+4
We know that sum is 120
So
x+x+1+x+2+x+3+x+4=120
Combine like terms
5x+10=120
Subtract 10 on both sides
5x=120-10
5x=110
Divide by 5 on both sides
X=22
The third number is x+2 = 22+2=24
