Step-by-step explanation:
400 divided by 5 equals= 80 so 80miles = 1 hour
Answer:
80 miles per hour.
Step-by-step explanation:
Start with the speed formula.
[tex]speed=\frac{distance}{time}[/tex]
In this scenario, the distance is [tex]400[/tex] miles, and the time is [tex]5[/tex] hours.
Substitute:
[tex]speed=\frac{400}{5}[/tex]
Divide.
[tex]400[/tex] ÷ [tex]5[/tex]
Solve:
[tex]400[/tex] ÷ [tex]5=80[/tex]
Can 65^ ,45^ and 80^ represent the measure of three angles of a triangle explain why or why not?

+) Six times the sum of a number and -1 is the same as 2 more than 8 times the number. Find the number.
Answer:
-4
Step-by-step explanation:
6(a+(-1)) = 8a + 2
then:
6(a-1) = 8a + 2
6*a + 6*-1 = 8a + 2
6a - 6 = 8a + 2
6a - 8a = 2 + 6
-2a = 8
a = 8/-2
a = -4
Check:
6(-4-1) = 8*-4 + 2
6*-5 = -32 + 2 = -30

y = -1
(-2, -1) the other endpoint
NEED HELP ASAP!!! Which of the following correctly uses absolute value to show the distance between −70 and 15? Question 6 options: 1) |−70 − 15| = |−85| = −85 units 2) |−70 + 15| = |−55| = 55 units 3) |−70 − 15| = |−85| = 85 units 4) |−70 + 15| = |−55| = −55 units
Answer:
3) |−70 − 15| = |−85| = 85 units
Step-by-step explanation:
Absolute value ignores negative values so the equation when finding the distance between −70 and 15 is 70 + 15 which equals 85.

Answer:
I have solved it u can have a look.
which expression is equivalent to the given expression. 3(x-7)+4(x^2-3x+9)
4x^2-5x+15 is the answer.
Step-by-step explanation:
= 3(x-7) + 4(x² - 2x + 9)
= 3x - 21 + 4x² - 8x + 36
= 4x² + 3x - 8x + 36 - 21
= 4x² - 5x + 15

3. If the point (3, 4) lies on the graph of the equation 3y = ax + 7, find the value of a.
Answer:
3/5
Step-by-step explanation:
3y = ax + 7
3(4) = a(3) + 7
12 = 3a + 7
5 = 3a
3/5 = a
Best of Luck!
x = 3
y = 4
Given Equation:3y = ax + 7
Solution:By putting the values of x and y, we get
3(4) = a(3) + 7
or, 12 = 3a + 7
or, 12 - 7 = 3a
or, 5/3 = a
Answer:a = 5/3
To Check:12 = 5/3(3) + 7
or, 12 = 12
LHS = RHS
Hence, Verified.

Answer:

Step-by-step explanation:
Empowerment is easy to know how to resolve one operation of this.
In empowerment there are 3 parts, base, exponent and power.
But in this case there is 1 additional, the sign, that is important to define the power.
In this case the 3 is the base, the exponent is 2, and the sign -
To resolve this operation you need to multiply the base by the times there are on the exponent, if there is a 2 like exponent, you multiply 2 times 3:
3x3 = 9
But because the sign, change the multiplication, if the sign is on base is:
-3x-3 = 9
The 2 operation give the same result because on negative rules, on multiplication, even negative numbers give always positive result and odd negative numbers give always negative result.
Then the power is 9

DaniElSabiondoA small toy car costs $3 a large toy car costs 5 times as much as the small one Aaron want to buy 1 of each which equation can be used to find the cost a of the 2 cars
Answer:
$18
Step-by-step explanation:
small -$3
large - $15
3+15=18
Answer: The equation is $3 + ($3 x 5)
Step-by-step explanation:
You add $3 to 3 multiplied by 5 to get the cost of the second car which will then give you the cost of both cars. Then you simplify and get $3 + $15 which gives us the answer $18. So the cost of both the cars is $18.

Answer:
2/3
Step-by-step explanation:
Simplify the following:
(8/27)^(1/3)
Hint: | For all n>=0, (m/n)^(1/3) = (m^(1/3))/(n^(1/3)).
(8/27)^(1/3) = (8^(1/3))/(27^(1/3)):

The required equations are 2x − 3=11 and 2x − 3=−11. Option C is correct.
Given that,
To determine what are the two equations to set up to solve the equation |2x−3|=11.
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given equation,
| 2x − 3| = 11
2x - 3 = ± 11
Taking (+)
2x - 3 = 11 - - - - - - - (1)
Taking (-)
2x - 3 = -11 - - - - - - - - (2)
Thus, the required equation are 2x−3=11 and 2x−3=−11. Option C is correct.

How do I do solving systems by substitution please help
The problem I'm on is x-y=-5 with x+y=1
Please show steps I need an answer before my report card comes in tomorrow
Answer:
I believe the answer is x=-2, and y=3.
Step-by-step explanation:
Given: x-y=-5
Fill in: -2-3=-5
Calculate: -5=5
-------------------------------
Given: x+y=1
Fill in: -2+3=1
Calculate: 1=1
Answer:
x = -2.
y = 3.
Step-by-step explanation:
x-y=-5
x+y=1
From the first equation
x = y - 5
Substitute this in the second equation:
y - 5 + y = 1
2y = 1 + 5 = 6
y = 3.
Substitute this into the second equation:
x + 3 = 1
x = -2.

Justin and Tyson are beginning an exercise program to train for football season and want to build muscle. Justin weighs 150 pounds and hopes to gain 2 pound per week. Tyson weighs 160 pounds and hopes to gain 1 pound per week. After how many weeks will they weigh the same amount?
Answer:
At 15 weeks they will both weigh 180
Step-by-step explanation:
150 + 2w = 195 - w
2w + w = 195 - 150
3w = 45
w = 45/3
w = 15 <=== they will weigh the same at 15 weeks
150 + 2(15) = 150 + 30 = 180...and they will both weigh 180 lbs
