So first you need to combine like terms:
7b -2/5 = 6b - 7/5
+2/5 +2/5
7b = 6b -5/5
7b = 6b -1
-6b -6b
b=-1

Let's solve your equation step-by-step.
7b−2/5=6b−7/5

Step 1: Simplify both sides of the equation.
7b+−2/5=6b+−7/5

Step 2: Subtract 6b from both sides.
7b+−2/5−6b=6b+−7/5−6bb+−2/5=−75

Step 3: Add 2/5 to both sides.
b+−2/5+2/5=−75+2/5
b=−1
Answer:b=−1

Which is the best example of a down payment?

Maru [420]

Answer:

Step-by-step explanation:

Proof by some contradictions:

D is not a good example because she does not pay anything upfront

B is not a good example because he pays everything upfront with some of the money from a third party

A is not right because the 500 is a security deposit, which is a different concept from a down payment

Therefore the answer should be C, where money is payed upfront and payed after he receives the product.

The trailer ramp is shaped like a triangle prism . The height of the ramp is 14 inches and the volume of the ramp is 4704 inches

Hatshy [7]

Answer:

A = 2167.73 cm²

Step-by-step explanation:

Given that,

A trailer ramp is in the shape of a triangular prism.

the height of the ramp, h = 14 inches

The volume of the ramp, V = 4704 inches²

We need to find the area of the base of the trailer ramp.

The volume of the triangular prism is given by :

$V=A\times h$

A is area of base and h is height

$A=\dfrac{V}{h}\\\\A=\dfrac{4704}{14}\\\\A=336\ \text{inches}^2$

A = 2167.73 cm²

So, the area of the base of the ramp is 2167.73 cm².
