Answer = x > 7.6

First, move the variable to the left hand side and change its sign:

2.5x - 4.2 + 1.5 > 3.4

Then move the constant to the right-hand side and change its sign:

2.5x - 1.5x > 3.4 + 4.2

Combine like terms:

X > 3.4 + 4.2

Add the numbers:

X > 7.6

Hope that helps!

Which sentence can represent the inequality x+251/1
wariber [46]

The sum of half of a number and three-fourths is at least five and one quarter.

It's all about making sense of an English statement. "half the sum" and "the sum of half" are two distinct expressions.

Additionally, "at least" and "not less than" have equivalent meanings, as do "not more than" and "at most."

It is an issue of matching the thoughts conveyed because all of the expressions are verbally expressed. That is a reading comprehension issue, not a math issue.

"A number is at least five and one quarter when divided by half and three-fourths."

In mathematics, a statement with unequal sides is referred to as an inequality. When a link leads to a non-equal comparison between two expressions or two numbers, it is referred to as an inequality in mathematics.

In this case, the equal sign "=" is replaced with any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠). There are numerous types of inequalities that can exist in mathematics, including absolute value inequality, rational inequality, and polynomial inequality.

liubo4ka [24]

Answer:

Required equation is: 25n = 875

Step-by-step explanation:

Let n be the number of minutes Jonathon read per day

Now

He read for 25 days and total 875 minutes

The equation will be:

25n = 875

We can solve this equation to find the number of minutes each day

Using Division property of Equality

\frac{25n}{25} = \frac{875}{25}\\n = 35

Hence,

Required equation is: 25n = 875
