Nina is 10 years younger than deepak. deepak is 3 times as old as nina. which system of equations can be used to find d, deepaks age and n, nina’s age

We can use linear system of equation with one variable.

Step-by-step explanation:

It is given that,Nina is 10 years younger than Deepak.

Deepak is 3 times as old as Nina.

To solve this using linear equation

Let d be the age of Deepak and n be the age of NIna

we can write,

n = (d - 10)   ---(1)

d = 3n    

d = 3(d - 10)  (2)

d = 3d - 30

3d - d = 30

2d = 30

d = 30/2 = 15

n - d - 10 = 15 - 10 = 5

Therefore the age of Deepak = 15 and age of Nina = 5

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
