Explain me step by step plz​

Answer:

28

Step-by-step explanation:

We know that the heights and bases of all of the parallelograms will be the same because they are equal, therefore, since the height of 2 parallelograms is 14, the height of one parallelogram is 14 / 2 = 7. Since the areas of all of the parallelograms are congruent, the area of one parallelogram is 308 / 4 = 77. The parallelogram area formula is A = bh where A, b and h are area, base and height respectively and we know both the area and height so we need to solve for b. Doing so we get 77 = b * 7 so that means b = 11. The length of y is two bases + 6 and since we know the base is 11, y = 11 * 2 + 6 = 22 + 6 = 28.

2 3/8 - 4 1/2 + 3 1/8 - (1/2)
UkoKoshka [18]

let's convert the mixed fractions to improper fractions firstly.

\bf \stackrel{mixed}{2\frac{3}{8}}\implies \cfrac{2\cdot 8+3}{8}\implies \stackrel{improper}{\cfrac{19}{8}}~\hfill \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}} \\\\\\ \stackrel{mixed}{3\frac{1}{8}}\implies \cfrac{3\cdot 8+1}{8}\implies \stackrel{improper}{\cfrac{25}{8}} \\\\[-0.35em] ~\dotfill

\bf \cfrac{19}{8}-\cfrac{9}{2}+\cfrac{25}{8}-\cfrac{1}{2}\implies \stackrel{\textit{using an LCD of 8}}{\cfrac{(1)19-(4)9+(1)25-(4)1}{8}}\implies \cfrac{19-36+25-4}{8} \\\\\\ \cfrac{4}{8}\implies \cfrac{1}{2}

To train for a marathon, Lily plans on running 4 miles per day for the first week and then increasing that daily distance by 1 m
user100 [1]

The equation which represent the problem is given by an = 4 + 1.00(n - 1)

<h3>How to write equation?</h3>

Number if miles Lily run per day first week = 4 miles

Additional miles per day each week = 1 mile

let

n = total miles

The equation:

an = 4 + 1.00(n - 1)

  • When n = week 2

an = 4 + 1(n - 1)

= 4 + 1(2 - 1)

= 4 + 1(1)

= 4 + 1

= 5 miles
