Answer:
(-4, -1) (see below)
Step-by-step explanation:
Substitution means that you actually replace, or "substitute," the value of the variable in.
Here, y = -1, so -3x - 8y = 20 can be written as:
-3x - 8 (-1) = 20
We can now solve for x:
-3x + 8 = 20
-3x = 12
x = -4
Putting this into (x, y) format equals:
(-4, -1)
Each peanut butter snack costs $2. Each chocolate snack costs $3. How much does it cost to buy 6 peanut butter snacks and 8 chocolate snacks? Write an equation.
Answer:
36
Step-by-step explanation:
8x3 is 24
6x2 is 12
when you add those together you get 36
Answer:
2 dollars x 6 Peanut butter snacks= 12 total
3 dollars x 8 chocolate= 24 total
24+12= 36 for the total all together
Step-by-step explanation:
You are buying 6 peanut butter snacks and they are $2 each so you multiply those numbers together for the total of Peanut butter snacks. You are also buying 8 things of chocolate and they are $3 each multiply them together you get the total for the chocolate. if you need the total for all together you add the totals together and you have your over all answer.

Answer:
1/6
Step-by-step explanation:
1/2 + 1/3 = 5/6

180=30 + 90 + z
z +120 = 180
z= 60
90-60=y

How do you solve the following equation
: X/-3 + 2=4
Answer:
For this equation you be inverse operation giving you the answer -6
further information down below :)
Step-by-step explanation:
Your goal for this is to isolate the variable which is x.
First, find the operation opposite of addition which is subtraction
When you add that operation to both sides with the constant(2)
2 and 2 cancel each other out, but to the for the term(4) 4-2=2
after that you have your new term which is x/-3=2
You do the same thing but to in division because the opposite of multiplication is division in this case you multiply -3 to both sides -3*-3 cancel each other out, now you have-3*2= negative times a positive equal negative in anyway so, overall you get -6.
To check:
you do the full equation now that you have isolated the variable, you now can do the operations normally which are. -6/-3=2 because when you divide a negative by a negative you get a positive end out with 2+2=4 which is correct and match the sum.
This means that our answer is correct :)
Complete the following statement. The distance around the edge of a figure is its ____.
Answer:
Perimeter
Hope it helps!
The distance around the edge of a figure is its Perimeter.
To complete the following statement. The distance around the edge of a figure is its ____.
Perimeter is the measure of the length of the figure on its circumference.
Since in the question blank, space is given following the definition,
The distance around the edge of a figure is perimeter because the measure of the boundary of any figure is termed as its perimeter.
For example, the Perimeter of the rectangle is the total measure of the two-time measures of length and width. For the Perimeter of the square, it is 4 times the length of one side. For the Perimeter of the circle, it is 2π times of radius.
Thus, the distance around the edge of a figure is its Perimeter.

Emily can walk 3/4 of a mile in 1/4 of an hour.
At this same rate, how long does it take Emily to walk 1 mile?
Answer:
20 minutes
Step-by-step explanation:
Method 1:
(0.75)/(0.25)=(1)/(x)
0.75*1.333333=1, so multiply 0.25 by 1.333333 to find the value of x!
0.25*1.333333=0.33333, or one-third of an hour, or 20 minutes.
Method 2:
(0.75)/(0.25)=(1)/(x)
Cross-multiply
0.75x=0.25
(0.25)/(0.75)=x
x=0.33333 hours
Emily will use 20 minutes or 1/3 hour to walk 1 mile.
Note that 3/4 = 0.75
1/4 hour = 1/4 × 60 = 15 minutes
Let the amount of time that it takes Emily to walk 1 mile be represented by x.
Therefore, the equation to solve the question will be:
0.75 /1 = 15/x
Cross multiply
(0.75 × x) = (1 × 15)
0.75x = 15
x = 15/0.75
x = 20
Therefore, Emily will use 20 minutes or 1/3 hour to walk 1 mile.

Why is the product of a rational number and an irrational number irrational? because the product is always a non-terminating, non-repeating decimal because the product is always a fraction because the product is always a negative number because the product is always a repeating or a terminating decimal
Answer:
Because the product is always a non-terminating, non-repeating decimal.
The product of a rational number and an irrational number will always be an irrational number. Then the correct option is A.
What is a rational number?If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.
The product of a rational number and an irrational number will always be an irrational number.

a = x2 - y2, 6 - 2xy, and C = x2 + y2
O 6, 8, and 10
O 5, 11, and 12
O 8, 15, and 17
O 3, 5, and 8
Given:
Consider the three number are given by:
[tex]a=x^2-y^2[/tex]
[tex]b=2xy[/tex]
[tex]c=x^2+y^2[/tex]
To find:
The three numbers are the Pythagorean triple generated by using 4 for x and 1 for y.
Solution:
We have,
[tex]a=x^2-y^2[/tex]
[tex]b=2xy[/tex]
[tex]c=x^2+y^2[/tex]
Substituting 4 for x and 1 for y, we get
[tex]a=4^2-1^2[/tex]
[tex]a=16-1[/tex]
[tex]a=15[/tex]
Similarly,

3) 1
4) 1.5 lbs
Step-by-step explanation:
1) First, 8505/315 = 27
2)I don't really have an explanation for this one-
3) 2/3 = 6/9. 6/9 + 3/9 = 1
4) 4/8 x 3 = 1.5
1. 2
8,505 ÷ 315 = 27
2. 2 ÷ 5
Fractions are division problems so it would be 2 divided by 5
3. 9/9 or 1
Make them have the same denominator
2/3 + 3/9 = 6/9 + 3/9 = 9/9 = 1
4. 1 ½
4/8 simplified is ½ so you should do ½ x 3 = 1 ½

A car uses 8 gallons of gasoline to travel 192 miles. How many gallons are used to go 144 miles? *
Answer:
6 gallons
Step-by-step explanation:
You can find this using the ration method.
If, 8 gallons : 192 miles
x gallons : 144 miles
We must find the value of x, which is the number of gallons used to travel 144 miles.
Cross multiply the ratios.
192 x = 8 × 144
192 x = 1152
x = 1152 ÷ 192
x = 6
∴ It takes 6 gallons to travel 144 miles.
