Answer:
I will use x as the distance traveled in 7 hours
450/5.5 = x/7.7 - set up proportion
5.5x = 3465 - cross products
5.5x/5.5 = 3465/5.5 - divide each side by 5.5
x = 630 - answer
hope this helps.
Step-by-step explanation:
Answer:a) L.C.M OF 2,3,5 is 30
THEREFORE=60/30+15/30÷10/30-6/30
=60/30+15/30×30/10-6/30(DMAS)
=60/30+3/2-6/30
=60+45/30 -6/30(ADDITION FIRST THEN SUBTRACTION.
=105/30-6/30
=105-6/30
=99/30
=33/10
b)(3+1/2)÷(2-1/2)=L.C.M IS 2,=(6+1/2)÷(4-1/2)=7/2÷3/2=7/3
Answer:
always have a solution
Step-by-step explanation:
A linear equation in standard form is given by:
Ax + By = C, where A,B, C are real numbers and A,B is not equal to zero.
Two linear equations with equations Ax + By = C and Dx + Ey = F
Therefore the first equation becomes: (A/B)x + y = C/B and the second equation becomes (D/E)x + y = F/E ]
Both equations are said have a solution if A/B ≠ D/E, they have no solution if A/B = D/E and they have infinite solutions if A/B = D/E, C/B = F/E.
Given that:
when a > b
ax + y = 8
bx + y = 5
Since a ≠ b, but a > b, the system has a solution
Answer:
because you can show the exact points an object is at
Step-by-step explanation:
For example: A car goes x many miles in y minutes. You can easily see how many miles the car goes in y minutes.
