Answer:
Streamers are $2.50 each
Balloons are $1.50 each
Step-by-step explanation:
Make a system of equations
3s + 15b = 30
2s + 4b = 11
Solve by elimination: multiply the top equation by 2 and the bottom equation by -3.
6s + 30b = 60
-6s -12b = -33
18b = 27
b = 1.5
Plug in 1.5 as b to find s
3s + 15(1.5) = 30
3s +22.5 = 30
3s = 7.5
s = 2.5
The streamers are $2.50 and the balloons are $1.50

Answer:
Area of Rectangle = LxB ; Area of Parallelogram = BxH ; Area of Triangle = 1/2xBxH
Step-by-step explanation:
Undermentioned are the formula, procedure, examples for calculating area of following geometric figures
- Area of Rectangle = Length (L) x Breadth (B)
Example : L = 10 ; B = 10
Area = L x B = 10 x 10 = 100
- Area of Parallelogram = Base (B) x Height (H)
Example : B = 10 ; H = 10
Area = B x H = 10 x 10 = 100
- Area of Triangle = 1/2 x Base (B) x Height (H)
Example : B = 10 ; H = 10
Area = 1/2 x B x H = 1/2 x 10 x 10 = 50
Answer:
its 10k
Step-by-step explanation:
Answer:
y = 3x - 9
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 )
Here m = 3 , thus
y = 3x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = 12 + c ⇒ c = 3 - 12 = - 9
y = 3x - 9 ← equation of line
