x=ferns ; y=ivy
12x+8y=260
6x+15y=240
x=60 -(15/6)y
12(60+ (15/6)y + 8y = 260
x=60 -(15/6)y
720 - 30y + 8y = 260
x=60- (15/6)y
-30y +8y= 260-720 ==> -22y= -460
x=60 -(15/6)y
y= (-460)/(-22)= 20.9090909091
y=20.90
x=60 -(15/6)×20.90= 7.75
×(ferns)=7.75$
y(ivy)=20.90$
Answer:
640
Step-by-step explanation:
first you have to do the 11-9 its gonna be 2 then you have to the cubic of 2 wich is 8 and after it you have to get 8 divided by 2 youre gonna get 4
after it you have to start from the left 320/4 equal to 80 than 80by 8 equal to 640
She originally started with 23.
We can tell this by working the equation backwards. Since she has 5 left and she had just given half to her brother, we know she had 10 a moment ago.
Before that, Mary had eaten a cookie. So we add 1 to the total and now have 11.
Before eating that cookie, she has given half to her sister, which would give her 22.
And before giving half to her sister, she had eaten the first one, which would give us 23 to start with.
Answer:
(x - 9)(x - 3)
Step-by-step explanation:
Step 1: Write out quadratic
x² - 12x + 27
Step 2: Factor
<em>What 2 numbers add up to -12 and multiply to 27?</em>
-9 and -3 add up to -12 and multiply to 27.
(x - 9)(x - 3)
