AC=4, AE=7, AD=10, what is the length of AB? <br> A: 1 3/7 <br> B: 2 1/2<br> C: 5 5/7<br> D: 17 1/2

Answer:

C. AB = 5\frac{5}{7}

Step-by-step explanation:

When two polygons are considered similar, the ratio of their corresponding sides would also be equal.

Since ∆ABC and ∆ADE are similar, \frac{AE}{AC} = \frac{AD}{AB}

\frac{7}{4} = \frac{10}{AB}

Cross multiply

7*AB = 10*4

7*AB = 40

Divide both sides by 7 to find AB

\frac{7*AB}{7} = \frac{40}{7}

AB = \frac{40}{7}

AB = 5\frac{5}{7}

If tim spends 1/3 each weekday sleeping and about 7/24 each weekday in school what fraction of a weekday does Tim spend either s
Ganezh [65]
Tim spends 1/3 each weekday sleeping and 7/24 in school. We can write 1/3 as 8/24 so we have a common denominator. Now we can see that Tim sleeps for 1/24 time of a weekday more then he spends in school.

I hope that's what you meant.

A system of equations is shown below.
weeeeeb [17]

Answer:

-12

Step-by-step explanation:

Step1: Add 3 to both sides of the equation

2x -3 = 5x +6

    +3         +3 = 9

Step2: subtract 5x from both sides of the equation

2x = 5x +9

-5    -5

Step3: divide both sides of the equation by the same term

-3x(/ -3) = 9(/-3)    

<h3>X=-3</h3>

Step4: multiply -3 with 2

-3x2= -6

Step4: subtract -6 with 3

-6 - 3= -9

<h3>Y=-9</h3>

Step5: add the -9 to -3

-9 + -3 = -12

ANSWER: -12
