Answer:

B. Subtraction; subtraction is the opposite of addition (to cancel out the 8)

How many solutions does the system of equations below have? y=2x+5y=2x+5

What is 15 percent of 18.95

A statement which has been proven to be true is called a

How do you solve 5x+7=3x-5

The following examples illustrate the commutative property of addition. 7 + 8 + 3 = 7 + 3 + 8 4.6 + 11.4 = 11.4 + 4.6 Study the examples, then choose the statement that best describes the property. a + b = a – b a + (b + c) = (a + b) + c a + b = a + c a + b = b + a

The answer is **Tim **must arrange at least 16 desks right to make $400 or x≥16

An inequality is an **inequation **separated by <,>≥,≤

Given here: Tim earns $150 each **week **plus 15.50 for each desk he assembles **right**, then let Tim assemble x desks right

Thus we have 150+15.50x=400

x=16.12

Hence, **Tim **must arrange at least 16 desks right to make $400 or x≥16

If a store owner bought a jacket for $20 and sold it for $25 the markup would be 40%

6pi:15pi

8:125

20pi:125pi

16pi:250pi

2:5

**Answer:**

It could be 2:5 or 6pi:15pi

**Step-by-step explanation:**

If you write the ratio of the surface area as a fraction, you would get . Simplifying it would leave . But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is . The answers would be 2:5 and 6pi:15pi.

**Answer:**

6π : 15π

2 : 5

17 units to the left of -6 on a **number line **is - 6 - 17 which equals to - 23.

A number line is exactly what it sounds like a **horizontal**, straight line with numbers spaced evenly apart throughout its length. Since it's not a ruler, the distance between each number is irrelevant; instead, the numbers on the line specify how they should be used.

The given statement 17 units to the left of - 6 on a number line can be interpreted as,

We we'll start at - 6 on the number line, Now we know moving to the **left **horizontal direction in a number line results in subtraction.

Therefore, 17 units to the left of - 6 on a number line is,

= - 6 - 17.

= - 23 units from the **origin **which should be labeled at zero.

47 minus 3 times the difference of 15 and 2

47-3(15-2)

Now we have to take the order of operations into consideration.

Parenthesis

Exponents

Multiplication/Division

Addition/Subtraction

Lets clear out the parenthesis.

47-3(15-2)

47-3(13)=47-39=8

Therefore, the final answer is 8

47 minus 3 times the difference of 15 and 2

47-3(15-2)

Now we have to take the order of operations into consideration.

Lets clear out the parenthesis.

47-3(15-2)

47-3(13)=47-39=8

Therefore, the final answer is 8

**Answer:**

**Step-by-step explanation:**

47 minus 3 times the difference of 15 and 2:

47 - 3(15-2) = 47 - 3(13) =47 - 39 = 8

VS

47 minus 3, times the difference of 15 and 2:

(47-3) (15-2) = (44)(13) = 572
