Step 1: -4(3x-1) becomes -12x+4
step 2: -12x+4=12-8x
step 3: add 12x to both sides, 4=12+4x
step 4: subtract twelve from both sides -8=4x
step 5: divide by 4, x=-2
The 3 in 350 represents 300
because 350=300+50+0, that is: 3 one hundreds +5 tens +0 ones
The 3 in 403, represents 3 because 403 = 400+3 that is 4 one hundreds, 0 tens and 3 ones.
Thus the 3 in the number 350 and the 3 in the number 403 are not the same.
The 3 in the number 350 is one hundred time the 3 in the number 403.
Answer: The 3 in the number 350 is one hundred time the 3 in the number 403.
Answer: The width is 12 feet, since the pool measures 10 by 12.
Step-by-step explanation:
Your aunt will need 120 square feet of land. I know this because you multiply the length by the width, it equals 120. Then I have to look for the perimeter, and I do this by adding the length twice and add the width twice. This would equal 42.
X = number of $85 trees, y = number of $95 trees
Logically, we can construct the expression 85x + 95y to represent how much Maple Grove spends on their trees in total. They want this cost to be less than or equal to $95,000. This means that the inequality has to be 85x + 95y ≤ 95000, either choice a or b. Since the community wants more $95 trees, they want y to be greater than or equal to x.
This means choice b: 85x + 95y ≤ 95000<span>, x</span>≤y is your answer.
Hope this helps!
2a^2b^3(4a^2+3ab^2-ab)=?
<span>
is what I presume you actually meant. </span>
<span>
Pull out the common factors of (4a^2+3ab^2-ab) and you will get </span>
<span>
a(4a+3b^2 -b) </span>
Substitute this back into the original equation and you get
<span>
2a^2b^3[a(4a+3b^2-b)] = </span>
2a^3b^3(4a+3b^2-b) =
<span>2a^3b^3(4a-b+3b^2)
</span>
