If you would like to solve the system of equations, you can do this using the following steps:
5p - 3r = 1 /*2
8p + 6r = 4
__________
10p - 6r = 2
<span>8p + 6r = 4
</span>__________
10p - 6r + 8p + 6r = 2 + 4
18p = 6
p = 6/18
p = 1/3
<span>5p - 3r = 1
</span>5 * 1/3 - 3r = 1
5/3 - 3r = 1
5/3 - 1 = 3r
5/3 - 3/3 = 3r
2/3 = 3r
r = 2/9
(p, r) = (1/3, 2/9)
The correct result would be <span>(1/3, 2/9)</span>.
2 hole pizzas equal 16 because 1 pizza has 8 slices so make 1/4 a decimal which is 4 4/16 equals 4 so for 4 friends 1/4 is left and do the same to the 21/3 which equals 7 so 7 +4 = half the amount to fead the friends
Simplify the expression:
7 - 5x - (3 + 5x)
Operate the parentheses. Each term changes its signs because the minus sign represents a -1:
7 - 5x - (3 + 5x) = 7 - 5x - 3 - 5x
Collect like terms:
7 - 5x - (3 + 5x) = 7 - 3 -5x - 5x
Simplify:
7 - 5x - (3 + 5x) = 4 - 10x
Answer: 4 - 10x
Answer:
3( 3+5)
Step-by-step explanation:
9 +15
Rewriting 9 as 3*3 and 15 * 3*5
3*3 + 3*5
Factor out 3
3( 3+5)
Answer:
Revolutions=37079108.61 rev
Step-by-step explanation:
First if all we have to make the units same to calculate the revolutions
Since distance gis gien in km and radius is given in m we will covert distance to m first.
Distance =S=65000km
Distance=S=65000km*1000m/km
Distance = S= 65000000m
Formula:
S=rθ
where
S is the distance
r is the radius
θ is the revolution in radian
θ=S/r
θ=65000000/0.279
θ=232974910.4 rad
Revolutions=θ/2π
Revolutions=232974910.4/2π
Revolutions=37079108.61 rev
