The distance from Town A to Town B on a map is 6 inches. The actual distance from Town B to Town C is 12 miles. The scale on the

Airida [17]

True since each inch is 4 miles you time 6 by 4
false it says it is 12 miles so you divide that by 4 to get the inches
false if A to B is 24 and B to C is 12 miles there is clearly much more then 4 miles between A and C

Pls solve the following equation. 25 = 5x - 2x + 10

Katarina [22]

Answer:

x = 5

Step-by-step explanation:

5x - 2x + 10 = 25

- 10 -10

5x - 2x = 15

3x = 15

divide 3 on both sides of the equal sign

x = 5

to check

5(5) - 2(5) + 10 = 25

25 - 10 + 10 = 25

25 = 25

How can I simplify this and show work?

svp [43]

$\frac{ \sqrt{3}}{ \sqrt{5} - \sqrt{6} } \\ = \frac{ \sqrt{3}( \sqrt{5} + \sqrt{6}) }{( \sqrt{5} - \sqrt{6})( \sqrt{5} + \sqrt{6})} \\ = \frac{ \sqrt{15}+3 \sqrt{2} }{5-6} \\ =- \sqrt{15}-3 \sqrt{2}$

For each of the following pairs a, b of integers, find the greatest common divisor d of a and b and express d in the form ar + b

Ray Of Light [21]

Answer:

Step-by-step explanation:

We are to find gcd of a and b using linear combination algorithm

a) 7 and 11. 1= 3(7)-2(11). Hence GCD =1

b) -28 and -63:

$-63 = -2(28)-7\\28=-4(7)+0$

7=-2(-28)+(-63)

So 7 is GCD

c) $126 = 91+35\\91 = 2(35)+21\\35 = 21+14\\21 = 14+7\\14 = 2(7)$

So 7 is GCD and 7 = 7(91)-5(126)

d) 630 and 132

GCD is 6.

$630=132(4) +102\\132=102+30\\102 = 30(3)+12\\30=2(12)+6\\12=2(6)$

6=630(-9)+43(132)

e) 7245 and 4784

GCD is 23

23 = 7245(35)+4784(-53)

f) 6499 and 4288

GCD is 67

67 = 6499(-31)+4288(47)
