A = 4 - 5c
a = 4 - 5(-1/2)
a = 4 - (-2.5)
a = 4 + 2.5
a = 6.5
Answer:
they are parallel
Step-by-step explanation:
given:
y = -2x + 3 ---- eq 1
and
-3y = 6x + 15 --- eq 2
We can rearrange equation 2 such that it looks like equation 1 for easily comparison by dividing both sides of equation 2 by -3
y = (6x+15) / (-3)
y = -2x - 5 ------eq 3
recall that for a linear equation in the form y = mx + b, "m" represents the slope of the equation.
In our case we can see that by comparing equation 1 and 3, that both equtions have the same m value (i.e. m = -2)
since both lines have the same slope, they are parallel.
You can "make 10" out of either the positive number or the negative one.
13 - 8
= (10 +3) -8 = 10 +(3 -8) = 10 -5 = 5
= 13 -(10 -2) = (13 -10) +2 = 3 +2 = 5

The latter approach would be used for computation using a soroban or abacus.
Answer:5
Step-by-step explanation:
If she ran around six times for one mile then if she ran around 1 time then that would be 1/6 of a mile so 5/6 of a mile would be 5 laps around
