Make sure they have all common denominators
\frac{2}{4} + \frac{4}{5} - \frac{7}{10}

\frac{2}{4} * \frac{5}{5} = \frac{10}{20}

\frac{4}{5} * \frac{4}{4} = \frac{16}{20}

\frac{7}{10} * \frac{2}{2} = \frac{14}{20}

\frac{10}{20} + \frac{16}{20} - \frac{14}{20}

Add \frac{10}{20} + \frac{16}{20} = \frac{26}{20}
\frac{26}{20} - \frac{14}{20} = \frac{12}{20}

To simplify, you must find the largest common factor which 4
In \frac{12}{20}
12÷4=3 and 20÷4=5

The answer is \frac{3}{5}

Consider the triangle A(4,0), B(-2,4), C(0,6)<br> What will be the equation of the altitude BM?
katovenus [111]

Answer:

BM: <u>y = (2/3) x + 16/3</u> with segment length of 2.77

Step-by-step explanation:

AC formula: m = (6-0)/(0-4) = -3/2

(y-0)/(x-4) = -3/2       y = (-3/2)x + 6   ... (1)

BM slope: BM⊥ AC   m = 2/3

BM formula: (y-4) / (x- -2) = (y-4) / (x+2) = 2/3

y-4 = 2/3 x + 4/3

<u>y = (2/3) x + 16/3</u>   ... (2)    -2≤x≤0.31

intercept of AC and BM (M) from (1) and (2): (-3/2)x + 6 = (2/3) x + 16/3

(13/6) x = 2/3      x = (2/3) / (13/6) = 4/13 ≈ 0.31

y = (2/3) (4/13) + (16/3) = (8/39) + (208/39) = 216/39 = 72/13 ≈ 5.54

M (4/13 , 72/13) or (0.31 , 5.54)

segment BM = √(4/13 - -2)² + (72/13 - 4)² = √1300/169 = 2.77

r-ruslan [8.4K]

Answer:

36 more students of grade 7 went on a trip than students of grade 6

Step-by-step explanation:

60 % of 110 students= 60/100*110= 66 students

85 % of 120 students= 85/100 * 120= 102 students

No of students of grade 7th more than 6th grade students= 102-66= 36
