there are 3 ponds and 6 ounces
3 * 16 = 48
48 + 6 = 54
Nancy bought 54 ounces of ground chunk beef
Answer:
-33rs
Step-by-step explanation:
First, distribute in the first part of the equation.
3r(4r-5s)=12r-15rs
Now, distribute in the first part of the equation.
2r(-6r-9s)=-12r-18rs
Combine this together.
12r-15sr-12r-18rs
Combine like terms. (12r and -12r will cancel out to 0.)
-33rs
Hope this helps! Have a wonderful day ^^
Answer: its the 3rd one
Step-by-step explanation:
There are 47 more because we are find “less” so we subtract to find the answer. 82-35=47
0.3(12x-16) = 0.4(12-3x)
0.3 is easier written as 3/10 and 0.4 easier written as 2/5, but in this case, 4/10 would help with the other fractions
3*12x/10-16*3/10 = 12*4/10 - 3x*4/10
36x/10-48/10 = 48/10 - 12x/10
since all the fractions are divided by 10, you can remove them totally by multiplying everything with 10
36x-48 = 48 - 12x
36x + 12x = 48 + 48
Here we moved the numbers, by adding them to both sides
48x = 48*2
we can find x by dividing by 48
x = 48*2/48
since we have a 48 both over and under the fraction we can cross out both
x = 2/1 = 2
