Vicky made some purchases at the

Mathematics
1 answer:
ELEN [110]3 years ago
5 0

Step-by-step explanation:

Vicky Bought:

Strawberries $3.50

Carrots $2.25

Flowers $9.95

Subtotal $3.50 + $2.25 + $9.95

= $15.70

5% Sales Tax (5% of Subtotal) = 5/100 x $15.70

= $0.785 (will not round off here as it is not the final answer.)

Total = Subtotal + 5% Sales Tax

= $15.70 + $0.785

= $16.485

= $16.49 (rounded off to nearest cent)

fomenos

Answer:

n = - 4

Step-by-step explanation:

6n + 9 = -3n - 21 - 6

6n + 3n = - 21 - 6 - 9

9n = - 27 - 9

9n = -36

n = -36/9

n = - 4

What is BC ?<br><br> Enter your answer in the box.
tamaranim1 [39]

<u>Answer-</u>

<em>The length of BC is </em><em>8 units.</em>

<u>Solution-</u>

Mid-Point Theorem-

The line segment connecting the midpoints of  two sides of a triangle is parallel to the third side and is congruent to one half of the third side.

As given,

AD = DB, so D is the mid point of AB

FA = FC, so F is the mid point of AC

Hence, DF is the line segment connecting the midpoints of  two sides of a triangle.

Applying the theorem,

BC = 2DF = 2×4 = 8 units

1/3x+2=3/4 how would I go about solving this???
Marizza181 [45]

Answer combine 1/2 and x.

X/2+2/3=1/6

Subtract 2/3 from both sides of the equation

X/2=1/6-2/3

Simplify the right side of the equation

-2/3 as a fraction with a common denominator, multiply by 2/2

X/2=1/6-2/3 x 2/2

Multiply 3 by 2

X/2 = 1/6 - 2/6 x 2

Combine the numerators over the common denominator

X/2 = 1-2 x2/ 6

Simplify the numerator

Multiply by -2 by 2

X/2 =1-4/6

Subtract 4 from 1

X/2= -3/6

Cancel the common factor of -3 and 6

Factor 3 out of -3

X/2 = 3(-1)/6

Cancel the common factor of 6

X/2 = 3 .-1/3.2

Rewrite the expression

X/2 = -1/2

Move the negative in front of the fraction

X/2= -1/2

Since both sides have the same Denominator the numerators must be equal.

X=-1

Solve by factoring.<br><br> x2 + 6x = - 9. Hint: This is a double root.
lutik1710 [3]
Subtract -9 from both sides.

x2+6x−(−9)=−9−(−9)

x2+6x+9=0

Factor left side of equation.

(x+3)(x+3)=0

Set factors equal to 0.

x+3=0 or x+3=0

x=−3

Answer:

x=−3
