7x - 3 + 4x = 19

7x + 4x - 3 = 19

11x - 3 = 19            | + 3

11x - 3 + 3 = 19 + 3

11x = 22            | : 11

11x : 11 = 22 : 11

x = 2

Answer:

B) 2

Step-by-step explanation:

(7x2) - 3 + (4x2) =19

14 - 3 + 8 = 19

11 + 8 = 19

19 = 19

the ecuation is true because both members are equals

when you have an expression like this you have to remeber that there are priorities

, first you have to solve the multiplications and division, then you have to solve the sum and the subtraction.

Enter the number in standard notation.
Jobisdone [24]
<h3>The length in standard notation is 0.05 meter</h3>

<em><u>Solution:</u></em>

Given that,

Jeremy measured the length of an ant as 5 \times 10^{-2}\ meter

We have to write the length in standard notation

From given,

Length = 5 \times 10^{-2}\\\\Length = \frac{5}{10^{2}}\\\\Simplify\\\\Length = \frac{5}{100}\\\\Length = 0.05

Thus the length in standard notation is 0.05 meter

<em><u>Method 2:</u></em>

length = 5 \times 10^{-2}\ meter

Use the exponent of 10 to determine how many places to move the decimal point

Since exponent is -2, is negative

Thus, we have to move the decimal point to right 2 places

5 \times 10^{-2} = 0.05

Thus the length in standard notation is 0.05 meter

Which of the following algebraic equations could represent the sentence, "The product of a number and five is 11"?
alexandr402 [8]

Answer: last option.

Step-by-step explanation:

You need to remember that a product is the result obtained by multplying the factors.

For example, in the following multiplication, the number 110 is the product and this is obtained by multiplying the factors 10 and 11:

10*11=110

Then,  being 11 the product, then you can know that:

"x" is a factor and 5 is the other factor.

Therefore, the algebraic equation that could represent the sentence "The product of a number and five is 11", is:

5x=11

How do you do<br>8(4x+7)=56​
lilavasa [31]
Multiply 8 to 4x and 7 so it looks like 32x +56=56 then you subtract 56 from to 56 which equals zero. Your equation should look like 32x=0. Divide 32 by 0 which equals 0. X=0
