8a -1+0.5b

Replace a nd b with the given values:

8(1/4) -1 + 0.5(10)

8 x 1/4 = 2

0.5 x 10 = 5

Now you have:

2 -1 + 5

2-1 = 1 +5 = 6

Answer is 6

Answer:

6

Step-by-step explanation:

Substitute the value of the variable into the expression and simplify.

Answer:

-6.3+d> 4 1/2

Step-by-step explanation:

She starts 6.3 miles west of her home. This is denoted by the (-). The store is 4.5 miles east of her home. East would be denoted by a (+). never be exactly 4.5 miles from her home. This would be denoted by a (>). Therefore the answer is: -6.3+d>4 1/2

The store is more than 4.5 miles east of her home meaning that it would never be exactly 4.5 miles from her home. This would be denoted by a (>). Therefore the answer is: -6.3+d>4 1/2

Answer:

x=52 and y=39

Step-by-step explanation:

52 + 39 = 91

52 - 13 = 39

What you would do is make the equation:

91=X+(X-13)

Then, you would solve for X and once you find X, you would subtract 13 from it.

The answers should be 52 and 39.

Answer: 29.5 inches tall.

Step-by-step explanation:

If Eva was 1.5 inches taller than her original height, she would be half of Maria’s height. So, we divide Maria’s height by two to find the height Eva would be if she was 1.5 inches taller.

62 / 2 = 31 inches

Next, to find Eva’s real height, we subtract 1.5 inches from the 31 inches. This is because Eva would only be half Maria’s height IF she was 1.5 inches taller, but she is not, so therefore we can deduct it.

31 - 1.5 = 29.5 inches

Therefore, Eva’s height is 29.5 inches tall. We can prove this, as well.

29.5 + 1.5 = 31 inches

31 * 2 = 62 inches

Therefore, Eva is 29.5 inches tall.

Answer:

-5np - r² + m + 45n - 6

Step-by-step explanation:

1) Eliminate redundant parentheses

m + 5n · (9 - p) - 6 - 1r²

2) Rearrange terms

m + 5n · ( - p + 9 ) - 6 - 1r²

3) Distribute

m - 5np + 45n - 6 - 1r²

4) Rearrange terms

-5np - r² + m + 45n - 6

=========================================================

Explanation:

The symbol that looks like an "E" is the uppercase greek letter sigma. It's used for summation. Specifically we are adding terms of the form -4+5n. What we do is replace n with values from the set {2,3,4,...,9,10}. After evaluating each item, we add up the results to get our final answer.

If n = 2, then -4+5n = -4+5*2 = 6 which is the first term.

If n = 3, then -4+5n = -4+5*3 = 11 is the second term

and so on until you reach n = 10.

A table is a handy way to keep track of everything (see below). Adding everything in the second column leads to the final answer of 234.

Step-by-step explanation:

4 (0.5x + 2.5y - 0.7x - 1.3y + 4)  

Use commutative property with like terms 4( 0.5 x - 0.7x + 2.5y - 1.3 y + 4)

Combine like terms 4 (-0.2x + 1.2y + 4)

Use distributive property -0.8x + 4.2y + 16

Answer: The answer is B.

Step-by-step explanation:

To figure out, you must first turn the mixed fraction (3 1/2) into an improper fraction (7/2). We can do so by:

3 * 2 = 6

6 + 1 = 7 or 7/2

Next, you follow the rules of KCF: Keep, Change, Flip. Keep the first fraction, Change the sign to its inverse operation, and Flip the second fraction.

Our original equation is 7/2 /(divided by) 3/2 = ?

1. Keep the first fraction

7/2 / 3/2 = 7/2 / 32

2. Change the sign to its inverse operation

7/2 / 3/2 = 7/2 * 3/2

3. Flip the second fraction

7/2 * 3/2 = 7/2 * 2/3

Now, solve.

7/2 * 2/3

7 * 2 / 2 * 3 = 14/6

To make this a proper mixed number, first simplify.

14/6 / 2 = 7/3

Now, figure out how many wholes are in 7/3.

7/3 / 3 = 2 1/3

This is because 2 times 3 is six, and 7 minus 6 equals 1, or 1/3.

Therefore, the answer is 7/3 OR 2 1/3 OR B

The value of x in x−8.2=−9.09 is 0.89.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

x−8.2=−9.09

Now, we have to solve for x

Add 8.2 on both side

x-8.2 + 8.2 = -9.09 + 8.2

x= 0.89

hence. the value of x is 0.89.
