Answer:
8 boards.
Step-by-step explanation:
Since he bought a few of each length. The only combination that works is when he bought 5 of the 4 ft long board so 4×5=20. Than he bought 3 of the 5ft boards 3×5=15. 20+15=35 ft worth of boards.
Answer:
B
Step-by-step explanation:
To complete the question, here are the answer choices:
<em>A) =A1*A2*A3*A4
</em>
<em>B) =A1*A2+A3+A1*A4
</em>
<em>C) =A1*(A2+A3+A1)*A4
</em>
<em>D) =A1*A2+(A3+A1)*A4</em>
<em />
We first need to multiply A1 and A2, this will give weight of passengers.
To get weight of luggage, we multiply A1 and A4.
We also need the checked weight to add to that, which is in A3. So then we add up A3 with those 2.
So we will get
A1*A2 + A1*A4 + A3
This is given in a different order in Option B. Hence, option B is right.
Given:
The two expressions are
To find:
Whether the given expression are equivalent or non-equivalent.
Solution:
If two expressions are looking different but they are equal after simplification, then they are called equivalent expressions.
The first expression is
The first expression is equal to the second expression after the simplification.
Therefore, the given expressions are equivalent.
Answer:
BC=11
Step-by-step explanation:
we need to find BC
and we know that
AB= x+2
AC=13
BC=2x+11
A, B and C are collinear
that means that
AB+BC=AC
x+2+2x+11=13
3x+13=13
3x=0
x=0
so BC=2(0)+11
BC=11
2 inches = 50 miles
1 inch = 25miles
0.5 inches = 12.5 miles
0.25 inches = 6.25
you need 1.25 so you do 25+ 6.25 and get 31.25. To the nearest mile this would be 31 miles.
