Answer:

a = 2 radical 19

Step-by-step explanation:

a^2 + 18^2 = 20^2

a^2 + 324 = 400

subtract 324 from both sides

a^2 = 76

square root both sides

a = radical 76

simplify radical to get 2 radical 19

-3 1/3b =5 what is the value of b?
zysi [14]

Answer:

b = (-3)/2

Step-by-step explanation:

Solve for b:

(-10 b)/3 = 5

Multiply both sides of (-10 b)/3 = 5 by -3/10:

(-3 (-10) b)/(10×3) = (-3)/10×5

(-3)/10×(-10)/3 = (-3 (-10))/(10×3):

(-3 (-10))/(10×3) b = (-3)/10×5

(-3)/10×5 = (-3×5)/10:

(-3 (-10) b)/(10×3) = (-3×5)/10

(-10)/10 = (10 (-1))/10 = -1:

(-3-1 b)/3 = (-3×5)/10

(-3)/3 = (3 (-1))/3 = -1:

--1 b = (-3×5)/10

(-1)^2 = 1:

b = (-3×5)/10

5/10 = 5/(5×2) = 1/2:

Answer:  b = (-3)/2

Answer:

C. 7x+10

Step-by-step explanation:

First, distribute the 2

2(x+5) +5x

2*x+2*5 +5x

2x+10+5x

Combine like terms

2x+5x+10

D-10-2d+7=8+d-10-3d
TEA [102]

Solution,solve\:for\:d,\:d-10-2d+7=8+d-10-3d\quad :\quad d=1

Steps:

d-10-2d+7=8+d-10-3d

\mathrm{Subtract\:}d-10\mathrm{\:from\:both\:sides},\\d-10-2d+7-\left(d-10\right)=8+d-10-3d-\left(d-10\right)

\mathrm{Refine},\\-2d+7=8-3d

\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides},\\-2d+7-7=8-3d-7

\mathrm{Simplify},\\-2d=-3d+1

\mathrm{Add\:}3d\mathrm{\:to\:both\:sides},\\-2d+3d=-3d+1+3d

\mathrm{Simplify},\\d=1

\mathrm{The\:Correct\:Answer\:is\:d=1}

\mathrm{Hope\:This\:Helps!!!}
