What is the answer to 4a + 26 = 50 + 6a

Answer:

87

Step-by-step explanation:

We know Heather recieved grades of 80, 75 and 86.

Let's find her average on those 3 tests.

80 + 75 + 86 = 241   Since there are 3 tests we divide by 3.

241/3 = 80.3333   Is her aveerage on the first 3 tests.

She need to average 82 so we can write an equation with t being the score on her 4th test.

[tex]\frac{80 + 75 + 86 + t}{4} = 82[/tex]

[tex]\frac{241 + t}{4} = 82[/tex]         Multiply each side by 4

([tex]\frac{241+t}{4}[/tex]) * 4 = 82 * 4         4 on the left will cancel

241 + t = 328     Subtract 241 from each side

241 - 241 + t = 328 - 241

t = 328 - 241

t = 87

Heather must get an 87 to have an average score of 82.

Answer:

140

Step-by-step explanation:

25x10 = 250

250/2 = 125

125+15 = 140

Hey there!

25 * 10) / 2 + 15
= 250 / 2 + 15

= 125 + 15

= 140

Therefore, your answer is: 140

24a³

Step-by-step explanation:

Simplify, then,  2.1  2³ divided by 2¹= 2 (³_¹)= 2²

( 3 . 4³ .2.   =24a³.

Simplification of an expression is making it as simple as possible. The simplified form of the considered expression is given by: Option D: [tex]72a^3[/tex]

If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\ a^b \times a^c = a^{b+c}\\\\^n\sqrt{a} = a^{1/n}\\(ab)^c = a^c \times b^c[/tex]

For the given case, the expression is simplified by using the given rules as:

[tex][3(2a)^{3/2}]^2 = 3^2 \times (2a)^{\dfrac{3}{2} \times 2} = 9 \times (2a)^3\\[/tex]

[tex][3(2a)^{3/2}]^2 = 9 \times 8 \times a^3 = 72a^3[/tex]

Thus, the simplified form of the considered expression is given by: Option D: [tex]72a^3[/tex]

Step-by-step explanation:

Answer:

Positive

Step-by-step explanation:

[tex]\frac{2}{5}-(-\frac{5}{6})[/tex]

Remember, a number minus the negative of a number would be equal to that first number plus that second number but not negative. In other words:

a - (-b) = a + b

So:

[tex]\frac{2}{5}-(-\frac{5}{6})=\frac{2}{5}+\frac{5}{6}[/tex]

The sum of two positive numbers would be a positive number. Because of this, we can see that the value would be positive.

I hope you find my answer and explanation helpful. Happy studying. :)

Step-by-step explanation:

(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)

Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.

We know that (n - 2) + n + (n + 2) = 78,

so 3n = 78, and n = 78/3 = 26.

Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.

Step-by-step explanation:

Hope this helps!

The polynomial 3x²y² − 5xy² − 3x²y² + 2 x 2 after fully simplified has 2 terms and a degree of 2, so option A is correct.

A polynomial is a mathematical expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminate (also known as variables) and coefficients.

Given:

3x²y² − 5xy² − 3x²y² + 2 x 2

Simplify the above expression,

3x²y² − 5xy² − 3x²y² + 2 x 2 = -55xy² + 4

As you can see from the expression, it has the two-term and highest degree of 2

Therefore, the polynomial 3x²y² − 5xy² − 3x²y² + 2 x 2 after fully simplified has 2 terms and a degree of 2.

Answer:

The answer is that it is a rational number because it is a terminating decimal

Step-by-step explanation:

0.62581 is a rational number.

Rational numbers are numbers that can be written as the ratio of two integers. For example: 1/2, 3/4, are rational numbers.

Irrational numbers, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.

Now the given number is,

0.62581

Now here we see that the numbers after decimal are terminating and non-repeating.

Also the digit after decimal stops.

Hence the number 0.62581 is rational.

Answer: 36

Step-by-step explanation:

Yes your answer is correct.

Yes, you did it correctly.

We have two opposite quantities.

We have to show that opposite quantities combine to make zero.

Any quantity with both magnitude and direction is called vector quantity.

Two vectors are said to be equal and opposite if they have same magnitude and angle of 180 degrees between them.

According to the question -

Assume a number line and mark a number say  'x'  after 0 and a number  

'-x' before zero. These two numbers represent the quantities with same magnitude. And it can be easily seen that the angle between line from center point 'O' to 'x' and the line from 'O' to '- x' is 180 degrees. Hence, these two equal and opposite quantities which will give a resultant value of = + x + (- x) = + x - x = 0
