Y=mx+b
3= -1/2(6) + b
3= -3+b
3+3= b
b= 6
y= mx+b
2= -1/2x+ 6
2-6 = -1/2x
-4 = -1/2x
-4•-2 = -1/2x •-2
x = 8

The amount saved by Rita is $25.
Given that, the skateboard Rita wants to buy is 6 dollars less than 3 times the amount she has saved. The skateboard is 69 dollars.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the unknown number be x.
Now, 3x-6=69
⇒ 3x=75
⇒ x=75/3
⇒ x= 25
Therefore, the amount saved by Rita is $25.

Answer:
The answer of your question is: x = 5
Step-by-step explanation:
It's and isosceles triangle then ∠ A = ∠C
73 = 8y - 7
8y = 73 + 7
8y = 80
y = 80 / 8
y = 10
∠ C = 8(10) -7
∠ C = 73°
The sum of the internal angles in a triangle equals 180°
∠A + ∠B + ∠C = 180°
73° + (6x + 4) + 73° = 180° Substitution
6x + 4 = 180 - 73 - 73
6x =34 - 4
6x = 30
x = 30 / 6
x = 5
Answer:
4660194 metric ton
126802560 gallon
Step-by-step explanation:
1 cm = 0.01 m
6 km = 6000 m
8 km = 8000 m
Volume = 0.01 m x 6000 m x 8000 m = 480000 m³
480000 m³ = 480000000 kg of water (density of water = 1000kg/m³)
103 kg = 1 metric ton
480000000 kg = 480000000 / 103 = 4660194 metric ton
1 m³ = 264.17 gallon
480000 m³ = 480000 x 264.172 = 126802560 gallon
