Answer:

Ok so 5 and tens least common denominator is 10. So 6/10- 2/10 (1/5×2=2/10)= 4/10. so now take 4/10 and 1/4 and find the lcm Which is 20 so 4/10×2 is 8/20+10/20=

18/20

$\\ \sf\longmapsto \dfrac{6}{10}-\dfrac{1}{5}+\dfrac{1}{4}$

$\\ \sf\longmapsto \dfrac{2-4+5}{20}$

$\\ \sf\longmapsto \dfrac{-2+5}{20}$

$\\ \sf\longmapsto \dfrac{3}{20}$

Can you help me on this problem -22+8v=7(4v-6)

astra-53 [7]

v = 1

explanation:

-22 + 8v = 7(4v - 6)

distribute 7 into 4v - 6

-22 + 8v = 28v - 42

subtract 8v from both sides

-22 = 20v - 42

add 42 to both sides

20 = 20v

divide by 20 on both sides

1 = v

$(12*4)+(12*\frac{7}{12})$ =

48+7 =

55 eggs

Number of eggs after breakfast:

12*3 $\frac{1}{12}$ =

(12*3)+(12*1/12)=

36+1 =

a )

Sum of the interior angles of any triangle equals 180° .

Thus :

$angle \: A + angle \: B + angle \: C = 180° \\$

$35° + 3(x+2)° + 52° = 180°$

$35° + 3x + 6° + 52° = 180°$

$3x + 93° = 180°$

Subtract sides 93°

$3x + 93° - 93° = 180° - 93°$

$3x = 87°$

Divide sides by 3

$\frac{3x}{3} = \frac{87}{3} \\$

$x = 29°$

________________________________

b )

$angle \: C = 3 ( x + 2 ) °$

$angle \: C = 3 ( 29+ 2 ) °$

$angle \: C = 3 ( 31 ) °$

$angle \: C =93 °$
