ANEK [815]

Answer:

24

Step-by-step explanation:

the height of a triangle is A=(b·h)÷2

We know the area and base so replace: 72=(6×h)÷2

Solve:

72=(6×h)÷2

·2         ·2

144=6h

÷6   ÷6

h=24

24 yards

Solve the inequality 5x7 < 2x - 1
Vanyuwa [196]

x is strictly less than 2 or x ∈ (-∞, 2)

Given: inequality 5x - 7 < 2x - 1

What are inequalities?

Inequalities are statements that are represented as comparison between two or more numbers or algebraic expressions.(strictly less, strictly great, greater, lesser)

Solving the given equation:

5x - 7 < 2x - 1

=> 5x - 7 - 2x < 2x - 1 - 2x

=> 3x - 7 < -1

=> 3x - 7 + 7 < -1 + 7

=> 3x < 6

=> x < 2

Therefore, x is strictly less than 2.

Hence x ∈ (-∞, 2)

The number line is attached below.

The value of y varies directly with x. If x = 15, then y = 12. What is the value of y, when x = 21?
Andrei [34K]

Answer: 16.8

Step-by-step explanation: if x= 15 and y =12 we know that y =.8 of x or 4/5 of x.  Knowing this we can divide x (21) by 5 and get 4.2.  We can then multiply this and get 16.8 which is 4/5 of x(21).  y=16.8
