Answer:
Cool dude... very unique?
#2
2x - 4y = -2
2x + 3y = -16
------------------subtract
-7y = 14
y = 14/-7
y = -2
2x - 4y = -2
2x - 4(-2) = -2
2x + 8 = -2
2x = -2 -8
2x = -10
x = -10/2
x = -5
answer x = -2 and y = -5
check:
2(-5)- 4(-2) = -2
-10 +8 = -2
-2 = -2.....true
2x + 3y = -16
2(-5)+3(-2) = -16
-10 + (-6) = -16
-16 = -16...true
Answer:
Step-by-step explanation:
First question 1 = 0.3 = 0.7
Second question 60/5=12 so 12 hours
Third question first find lcm so 6
2 3/6 and 7 2/6
2.5 + 2.5 = 5 so 2 cakes
Fourth question
729/14 um calculator but ok 729/14=52.07 so 52.1
You said you'd report me if i only did 3,2,or 11 but i did 4 so i think im fine
Act like it's a whole circle and find the perimeter, then divide by 2.
P = 2 * pi * r
P = 2 * 3.14 * 9
P = 56.52
Now divide by 2:
P = 28.26
