Answer:
Step-by-step explanation:
The common difference, d, is 3, because the number of squares goes up by 3 each time.
d = 3
Number of squares in nth figure is:
a(n) = 4 + d(n - 1)
4 is the initial number of squares, d is how many it goes up each time, and we take n-1 because you need to account for the initial number of squares.
a(n) = 4 + d(n - 1)
For n = 200
a(n) = 4 + d(n - 1)
a(200) = 4 + 3(200-1)
a(200) = 4 + 3(199)
a(200) = 4 + 597
a(200) = 601
Use the Distributive Property to simplify the expression.

Answers
Answer:
n + 3m + 2, or also the same as 1n + 3m + 2
The simplified form of the given expression is [tex]n+2+3m[/tex].
Important information:
The given expression is [tex]\dfrac{1}{2}(2n+4+6m)[/tex].Distributive Property:[tex]a(b+c)=ab+ac[/tex]
We have,
[tex]\dfrac{1}{2}(2n+4+6m)[/tex]
Using the Distributive Property, the given expression can be written as:
[tex]=\dfrac{1}{2}(2n)+\dfrac{1}{2}(4)+\dfrac{1}{2}(6m)[/tex]
[tex]=n+2+3m[/tex]
Thus, the simplified form of the given expression is [tex]n+2+3m[/tex].

Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time, which expression can be used to determine the distance he walked each minute?
12 divided by three-fourths
12 times three-fourths
Three-fourths divided by 12
Four-thirds divided by 12
Answers
Answer:
Your answer would be C.
Step-by-step explanation:
The expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time.
As we know,
The distance = speed x time
Speed is constant
distance ∝ time
3/4 ∝ 12
1 ∝ x
Here x is the distance traveled each minute
3/4 = 12/x
Or
x = 12/(3/4)
1/4 = 4/x
x = 16 miles
Thus, the expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.

118/13= 59/z
what is the answer??
Answers
Answer:
[tex]z = 6.5[/tex]
Step-by-step explanation:
If we take a look at the problem, we are solving for z.
[tex]\frac{118}{13} = \frac{59}{z}[/tex]
To figure it out, we have to cross multiply. So we take [tex]118 * z[/tex] and [tex]59 * 13[/tex], which gives us [tex]118z =767\\[/tex]. Next, we divide both sides with 118.
[tex]\frac{118}{118}z=\frac{767}{118}\\ \\z = 6.5[/tex]
Then, we get 6.5 as our answer!
