A triangle with dilated by scale factor of 6. If sin a°= 4/5 and segment DE measures 30 units how long is EF? EF=15.5 units
EF=15 units
EF=30 units
EF=37.5 units

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

the answer is d
