Answer:

14.5

Step-by-step explanation:

\frac{2}{7}  =  \frac{5}{m + 3}

2(m + 3) = 7 \times 5

2m + 6 = 35

2m = 35 - 6

2m = 29

m = 14.5

Answer:

m = 14.5

Step-by-step explanation:

\frac{2}{7} = \frac{5}{m+3} ( cross- multiply )

2(m + 3) = 35

2m + 6 = 35 ( subtract 6 from both sides )

2m = 29 ( divide both sides by 2 )

m = 14.5

Khan Academy Question
Mama L [17]

Answer:

84

Step-by-step explanation:

Since we are given line OP perpendicular to line DR, then angles PDR and ODR are right angles.

Angles PDA and ADR are complementary.

Angles ODU and UDR are complementary.

Angles ADR and UDR are given as congruent.

We can conclude that angles PDA and ODU are congruent.

By AA Similarity, triangles APD and UMD are similar.

DP/DM = PA/MU

3.75/10 = 4.5/MU

3.75MU = 10 × 4.5

MU = 12 (altitude of triangle DUO)

OD = OM + MD =  4 + 10 = 14 (base of triangle DUO)

area = base × height / 2

area = 14 × 12 / 2

area = 84

A company developed the following linear model to help budget annual expenses over time. In this model, x represents the number
ollegr [7]
The only reasonable answer I could think for this is "A.<span>The company's expense budget for 2009 was $189,785."
I believe this because since x is the years after 2009 then you wouldn't times that by the expense budget for that year or any year eliminating B and C. When finding the total expense budget for this you would have to take in account the budget from 2009 so that would lead it to add 189,758. Since we are talking about after 2009 then D would be eliminated since 2008 is before 2009. 
I hope this helps! Good luck!</span><span>

I have some questions that need to be answered fast.<br><br> 1. 42/j = 35/55
Novay_Z [31]

\frac{42}{j}  =  \frac{35}{55}

to solve for j first you need to cross multiply;

j × 35 = 42 × 55

35j = 2,310

j = 2,310 ÷ 35 (did the inverse operation)

j = 66

Hope that helps :D

kari74 [83]

Once we sort through the tax terms, that's just

9258.13 - 3650 - 5700 = $ -91.87
A negative numbers mean the deduction and exemption sheltered all of his income, so he has $0 taxable income, choice D.
