A.If we use the same definition for multiplication, what should the value of 3x(-5) be ?
B.If the distributive property works for both positive and negative numbers, what expression would be equivalent to 3x(5+(-5))?(Hint: You can use additive inverse property)
C.Use what you know from parts (a) and (b). If we can multiply signed numbers in any order, what should the value of (-5) x 3 be? If the distributive property works for both positive and negative numbers, what expression would be equivalent to (-5)x(3+(-3)?

Hey there!
A. 3x5 is 15! However since one of the number is a negetive, we must add a negetive sign to the 15, making it -15!
Remember this: A negetive number times a negetive number is a posititve number, but a negetive number times a positive number is a negetive!
B. 5+-5 is equal to 0, so 3x0 is 0!
C. No matter which way you mutliply it, whether it's -5x3 or 3x-5, the answer will always be -15! (-5)x(3+-3) is: 3+ -3 is 0, so -5 times 0 is the same thing as 5x0, which is still 0!
D. Like I said before, a negetive times a negetive is a positive, so -3x-5 is the same as saying 3x5, which is 15!

equation to solve how many d in the amount of w=1/50=w/d or 1*w=w and 50*w=d
student will have 2600 dollars in 52 weeks
Step-by-step explanation:
m=y2-y1/x2-x1
150-100=50
3-2=1
50/1=50
slope=50
b=(y=mx+b)
150=50(3)=b
50*3=150
150-150=0
150-150=0

interoperate your solution in the context of the problem.
f(10)=1.75r+9
Answer:
Simplifying
f(r) = 5 + 1.75r
Multiply f * r
fr = 5 + 1.75r
Solving
fr = 5 + 1.75r
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'r'.
f = 5r-1 + 1.75
Simplifying
f = 5r-1 + 1.75
Reorder the terms:
f = 1.75 + 5r-1
Step-by-step explanation:
tada i think
Let's solve for f.
f(10)=1.75r+9
Step 1: Divide both sides by 10
10f/10 =1.75r+9/10
Answer : f=0.175r+9/10

Julie is out shopping and finds a $96.00 basketball that was marked down by 25%.
How much was the item originally?
Answer: The original price of the basketball was $128.
Step-by-step explanation: The new price is 25% less than the original. That is the same as 25% from 100% is 75%.
So we can use that to calculate the original price:
96 = .75x . divide both sides by .75
96/.75 = x
128 = x That is the original price.
Check: $128 × .25 = $32, the amount of the discount.
$128 - 32 = $96 That is the price Julie paid.

At the fair, Hunter bought 3 snacks and 10 ride tickets. Each ride ticket costs $1.50 less than a snack. If he spent a total of $24.00, what was the cost of each snack?
A) $4
B) $2
C) $5
D) $3
Answer:
d if this helped mark brainliest
Step-by-step explanation:
Each ride ticket is 1.50 less than each snack
t = s - 1.50
hunter spent a total of 24
if hunter bought 3 snacks and 10 ride tickets.
3s + 10t = 24
3s + 10(s - 1.50) = 24
3s + 10s - 15.00 = 24
13s = 39.00
s = 3
t = 1.50
Answer:
D
Step-by-step explanation:
Let s represent the cost of snacks and r represent the cost of the ride tickets.
We know that Hunter bought 3 snacks and 10 ride tickets. This cost in total $24. So:
[tex]3s+10r=24[/tex]
We know that each ride ticket cost $1.50 less than a snack. So, we can write that:
[tex]r=s-1.5[/tex]
We can find s using substitution. Substitute the above equation into the first equation. This yields:
[tex]3s+10(s-1.5)=24[/tex]
Distribute:
[tex]3s+10s-15=24[/tex]
Combine like terms:
[tex]13s-15=24[/tex]
Add 15 to both sides:
[tex]13s=39[/tex]
Divide both sides by 13:
[tex]s=3[/tex]
So, the cost of a snack is $3.
Our answer is D.

The first side of a triangle is 7 cm shorter than twice the second side. The third side is 4 cm longer than the first side. The perimeter is 90 cm. Find the length of all three sides.
Please answer! Im giving half of all my points!!
Answer:
first side = 33
second side = 20
third side = 37
Step-by-step explanation:
first side = 2x-7
second side = x
third side = (2x-7)+4
(2x - 7) + x + (2x - 7) + 4 = 90
5x - 14 + 4 = 90
5x - 10 = 90
+10 +10
5x = 100
x = 20
first side:
2(20)-7
40 - 7 = 33
second side: 20
third side:
(2(20) - 7) + 4
(40 - 7) + 4
33 + 4 = 37

Two sides of a triangle have lengths of 7 and 15. Which inequality represents the possible lengths for the third side?
A) 8 < x < 7
B) 7 < x <15
C) 8 < x < 15
D) 8 < x <22
Answer:
D
Step-by-step explanation:
From the triangle inequality, we know that the two small sides must be greater than the largest side. Let's let x be the third side:
[tex]7+15>x[/tex]
However, 15 can also be our largest side. So:
[tex]7+x>15[/tex]
Let's solve for x for both inequalities.
First inequality:
[tex]7+15>x[/tex]
Add:
[tex]22>x[/tex]
Flip:
[tex]x<22[/tex]
Second inequality:
[tex]7+x>15[/tex]
Subtract 7 from both sides:
[tex]x>8[/tex]
So, we have the compound inequality:
[tex]x>8\text{ and } x<22[/tex]
Combine:
[tex]8<x<22[/tex]
Our answer is D

Sam invested $14,000 in a stock that was expected to show an 18% increase in value. If all goes as expected, what will Mr. Bronson’s stock be worth after one year?
a
$11,480
b
$2,520
c
$16,520
d
$252,000
25p
Answer:
C
Step-by-step explanation:
we can convert 18 percent to .18 and then we can multiply 1.18 by 14000 to get our answer. if you don't do the extra 1 before the decimal you will get the 18 percent then have to add it to 14000 so adding the 1 before doesn't affect anything, it just makes it easier, without it it would be a two step problem (adding the .18 to 14,000).

The sale price of an item is $160 after a 20% discount. What was the original price of the item?
Answer:
200 sorry read that wrong
Step-by-step explanation:
Answer:
The original price of the item is $200.
Step-by-step explanation:
Let the original price be 'x'.
The sale price of an item is $160 after a 20% discount.
i.e. original price - 20% of original price = $160
x-20/100x=160
x-0.2x=160
0.8x=160
x=160/0.8
x=200
Therefore, the original price of the item is $200.
