Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Step-by-step explanation:
Let x= height of each fir tree, y = height of each pine tree.
As per given, we have
x+y = 21 (i)
4x=y+24 (ii)
From (ii),
(iii)
Add (i) and (iii), we get

Put value of x in (i), we get

Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Okay the answer is r=47
Let's solve your equation step-by-step.<span>5+44=2+r
</span>Step 1: Simplify both sides of the equation.<span>5+44=2+r
</span>Simplify:<span>49=r+2
</span>Step 2: Flip the equation.<span>r+2=49
</span>Step 3: Subtract 2 from both sides.<span><span>r+2−2</span>=49−2</span>r=47
Answer:<span>r=<span>47

Answer:
I got you, give me a few minutes
1st one: 6x+12+6y
2nd one: -12a-20b
4th one: 2x times 18
Step-by-step explanation:
So tis is a ratio 16 is to 3 or 16:3
if use 64 tea bags then how many cups of sugar so
turn 16:3 into fraction
16:3=16/3 or 3/16, it doesn't matter
then you want to find 64:x or 64/x or x/64
we know that 16/3=64/x because it tis an equivalent ratio
so 16/3=64/x
multiply both sdies by (3 times x)
16 times x times 3/3=64 times 3 times x/x
16 times x=64 times 3
16x=192
divide both sdies by 16
x=12
theanswer is 12 cups of sugar
