Half The Sum Of 10 And A Number - test

Webhow do you define a variable and write an expression for each phrase:

Let’s assume that the.

Web — let's say that our number that we don't yet know the value of is x.

Web — how do you write the expression for:

Let the number be x.

Web — you know that you're dealing with.

Weblet's call the number we're trying to find x.

Web — sum says we're adding things together:

Write the equation based on the given information:

The sum of a number and 10 is x+10.

We have an unknown number (let's call it x) as what we're adding, and we have.

X/2 + 2x = 10.

'the square of 3 times a number' is.

Let the number be x x x.

So we can write an equation:

2x + \frac {x} {2} = 10 2x+2x=10.

+ and it equals 10:

The sum of twice a number and half the number is 10?

First, let's call a number n.

Let n represent a number.

Sum = 256. 25.

It is defined as the combination of constants and variables with.

Web — to solve the equation “the sum of twice a number and half the number is 10,” we can translate this statement into a mathematical expression.

According to the problem, the sum of twice the number (2x) and half the number (0. 5x) is 10.

Half of the sum is (x+10)/2.

A sum is the total amount.

Halving a number means dividing it by two, so the expression that shows the half of a number is #x/2#, since you.

Web — we can represent a number in general by #x#.

For example, 'the sum of a number and 3' is x + 3;

The sum means to add or + therefore, the sum of a number and 10 can be written.

A sum is the result of adding together a set of numbers.

That means that twice that number would be 2 times that number or 2x.

Add these things together.

See the entire explanation below:

Webthe expression (1/2)[x+10] represents the one half of the sum of a number and 10.

2x + 0. 5x =.

X + 4x /2 = 10.

Webdetailed step by step solution for the sum of twice a number and half the number is 10

+ = 10.

Of a number → this means that you're.

Web — just convert the sentence into an equation like so:

Given the sum of twice a number and half the number is 10.

Algebra expressions, equations, and functions variable.

Therefore, the required number is 4.

A sum → this means that you are adding something, so you're going to use the + sign;

2x + \frac {x} {2} = \frac {4x + x} {2} =.
