use the distributive property to write each expression as an equivelent expression then evaluate it 7(7-9)
Answers
Answer:
Equivalent expression of 7(7-9) is 7*7 - 7*9
and solution is - 14
Step-by-step explanation:
Distributive property is one in which multiplying a sum of numbers with a particular numbers will give same result as multiplying each term term from sum individually with the particular number and then adding it together.
Example
a(x+y) = ax + ay
here either we first add x and y then multiply it with a
or
we multiply a with x and a with y individually and then add them, both will give the same result.
__________________________________
Given
7(7-9)
using Distributive property
7(7-9) = 7*7 - 7*9
Thus,
equivalent expression of 7(7-9) is 7*7 - 7*9
solving
7*7 - 7*9 = 49 - 63 = -14

m = 5/12
explanation: to get the two fractions (2/3 and 1/4) to have the same denominator, we multiply 2/3 by 4, both the top and bottom, and we also multiply 1/4 by three, both sides as well.
this results in 8/12 and 3/12, and when we subtract these two fractions, it gives us the fraction that the variable m represents

20 POINTSSSSSSSSSSSSSSSSSSSSS do these pairs of values (x and y) represent two quantities that are proportional x 1, 4,10,18 y 3, 8, 15, 27, A. no, because mot all pairs represent the same ratio. B, yes, because all of the pairs represent the same ratio. C. yes, because as x increases y increases. D. no, because not all of the x-values can be divided by 2 evenly
Answers
Answer:Answer: B) No, because not all of the pairs represent the same ratio
For each row, divide y over x
Row 1: y/x = 5/3 = 1.67 approximately
Row 2: y/x = 7.4 = 1.75
Row 3: y/x = 10/6 = 1.67 approximately
Row 4: y/x = 15/9 = 1.67 approximately
We see that row 2 has a ratio different from the others. If we were able to ignore this row, then the answer would be "yes x and y are proportional". However, we cannot ignore this row so that's why the answer is choice B.

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answers
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.

Tom and Katherine live in different towns which are linked by a bike trail. They agree to meet for a bike ride, and both set off from home at the same time. Tom rides north at a speed of 14 mph and Katherine rides south at 10 mph. The bike trail between their homes is 42 miles long. How long will it be before they meet?
Answers
Answer:
We can start by using the formula:
time = distance / speed
Let t be the time (in hours) for Tom and Katherine to meet.
Tom's distance = Tom's speed x time = 14t
Katherine's distance = Katherine's speed x time = 10t
Since they are riding towards each other, the total distance they cover is the sum of their distances:
Tom's distance + Katherine's distance = 42 miles
14t + 10t = 42
Simplifying:
24t = 42
t = 42 / 24
t = 1.75 hours
Therefore, Tom and Katherine will meet after 1.75 hours of riding.
