6*30 = 180
8*20 = 160
9*10 = 90
180+160+90 = 430 stickers
2 5/6 divided by 3 1/4 is like multiplying.
You turn both mixed fractions into improper fractions. Then flip 13/4 into 4/13 and multiply. I’m sorry if this doesn’t make sense.
17/6 x 13/4 to 17/6 x 4/13
17/6 x 4/13 = 68/78 = 34/39
Answer:
no
Step-by-step explanation:
No, it is not since 2 points have the same x-coordinate and different y-coordinates.
Answer:
(-1/2, 3)
Explaination:
Multiply the second equation by 2, then add the equations together.
(4x-y=-5)
2(-2x+3y=10)
Becomes:
4x-y=-5
-4x+6y=20
Then add the equations to eliminate x.
5y=15
then solve 5y-15 for y. (Divide both sides by 5)
5y/5 = 15/5
y= 3
Okay, now we have found y where going to plug it in an equation to solve for x
Going to chosse equation : 4x-y=-5
Subsitue 3 for y in 4x - y = - 5
4x - 3 = -5
( Add 3 to both sides)
4x - 3 + 3 = - 5 + 3
4x = -2
(Divide both sides by 4 )
4x/4 = -2/4
x= -1/2
