Answer:
v=12
Step-by-step explanation:
1/2v-12+20=14
Add.
1/2v+8=14
Subtract 8 from both sides of the equation.
1/2v=6
Divide 1/2 from both sides of the equation.
v=12

300 x 47 explain please
Answer:
I think u mean to just multiply 300 * 47 would equal 14,100
300
x 47
7*0 = 0 7*3=21 so 2,100
40*0 = 0 since 40 has a 4 you can take 4*3 and put a 0 on the end 4*3= 12 so 40*3= 120 so with so with the bonus 0's it would be 12,000
12,000
+ 2,100
14,100 so that means

A company sells three types of gift baskets. The basic basket has two movie passes and one package of microwave popcorn, and costs $15.50. The medium basket has two movie passes, two packages of microwave popcorn, and one DVD, and costs $37. The super basket has four movie passes, three packages of microwave popcorn, and two DVDs, and costs $72.50.
Create a system of equations and solve using matrices to find the price of each basket item.
The price of each movie is $7, the price of each microwave popcorn is $1.50 and the price of each DVD is $20.
Let x represent the cost of each movie, y represent the cost each microwave and z represent the cost of each DVD.
For the basic:
2x + y = 15.50 (1)
For medium:
2x + 2y + z = 37 (2)
For super:
4x + 3y + 2z = 72.50 (3)

Identify an equation in point-slope form for the line parallel to y-x-4 that
passes through (-1, 7).
O A y-7 - (x+1)
O B. y+1-(x-7)
O C. -?.5(x+1
O cy 7
y-
O D. yt? (x-1)
SUBMIT
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{3}{4}[/tex] x - 4 ← is in slope- intercept form
with slope m = [tex]\frac{3}{4}[/tex]
Parallel lines have equal slopes
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here (a, b ) = (- 1, 7 ) , then
y - 7 = [tex]\frac{3}{4}[/tex] (x - (- 1) ) , that is
y - 7 = [tex]\frac{3}{4}[/tex] (x + 1) → A
solve for x in the triangle
Answer:
x=9
Step-by-step explanation:
Since the sides are the same, the base angles must be the same
8x+2 = 10x-16
Subtract 8x from each side
8x+2-8x =10x-16-8x
2 = 2x-16
Add 16 to each side
2+16 = 2x-16+16
18 =2x
Divide by 2
18/2 =2x/2
9 =x
How do you solve Y+4= -3 (x-2)
Answer:
This problem is in Point Slope form:
To turn it to Slope-Intercept form, you must follow these simple steps below⤵⤵⤵:
Distribute -3 among everything inside the parenthesis to get y + 4 = -3x + 6.Subtract 4 from 6 to get y = -3x + 2.To turn it to Standard Form, you must follow these simple steps below⤵⤵⤵:
Use the Slope-Intercept form of this equation, in order to convert it.Add 3x on both sides of the equal sign, to get 3x + y = 2.Hope this helps you :)

- 2/7 divided by - 8/21
I like to use the way flip the second fraction then cross cancel then multiply.
(-2/7)/(-8/21)
= (-2/7)(-21/8) (cross cancel) so 8 / 2 = 4 and 21 / 7 = 3. The 7 and 2 becomes 1.
= (-1/1)(-3/4)
= 3/4 or decimal 0.75
Answer:
3/4
Step-by-step explanation:
(-2/7) / (-8/21)
= (-2/7) * (-21/8)
=(-2*-21) / (7*8)

Step-by-step explanation:
So, the first step to solving the problem is to find out what type of triangle it is
and what rule of goemetry we can use to solve it.
Finding What Theorem We Can Use
So, the first step is to figure out what theorem we can use to solve the problem and how they can help us. By looking at it, we can see that it is an Isosceles Triangle due to the two sides being equal and 1 side not being equal.
One Theorem used on the Isosceles Triangle is the Base Angles Theorem. This states that the bottom two angles of the sides on the Isosceles triangle are equal to each other. So in this case if we letter the triangle A on the top, B as the Left, and C as the right. It would say this:
[tex]<ABC= <ACB[/tex]
Since we know this rule, we can solve for the equation.
Solving
We can solve for this by using two things that we know:
+ Sum of all angles in a triangle is 180 degrees.
+ Bottom two sides are congruent.
Since we know that, we can solve for the answer:
[tex]1) <ABC + <BAC+<BCA=180\\2) <BAC = 80\\3) <ABC + <BCA=100\\4) 2<ABC=100\\5)<ABC=<BCA=50[/tex]
After solving, we know that x is 50 degrees!
Cheers!
