Answer: 6 faces 12 edges 8 verticies
Step-by-step explanation:
9×10^-3 + 24×10^-6 : 12×10-3
9×10^-3 + 2×10-3
11×10^-3
Answer:
False because of the way your trionomial is setup
given 2 variables and you only have one
Step-by-step explanation:
Step-by-step explanation:
0.777... is rational since it can be put in fraction form which is 7/9
note: if something can be put as an integer/integer its rational
Answer:
3x = 3 + 2y -------------> 3x - 2y = 3 {subtracted 2y from each side of top equation}
(-4/3)x + y = -2/3 ------> -4x + 3y = -2 {multiplied bottom equation by 3}
3x - 2y = 3 ------> 12x - 8y = 12 {multiplied top equation by 4}
-4x + 3y = -2-----> -12x + 9y = -6 {multiplied bottom equation by 3}
12x - 8y = 12
-12x + 9y = -6
--------------
y = 6 {added the two equations}
3x = 3 + 2y {original top equation}
3x = 3 + 2(6) {substituted 6, in for y, into top equation}
3x = 3 + 12 {multiplied}
3x = 15 {added}
x = 5 {divided each side by 3}
x = 5 and y = 6
