Answer:
80 minutes34.4 kmStep-by-step explanation:
Use the second equation to substitute for d in the first equation.
0.43t = 0.33t +8
Subtract 0.33t from both sides
0.10t = 8
Multiply by 10
t = 80 . . . . . . Michelle will catch Jen in 80 minutes
The distance traveled will be ...
d = 0.43t = 0.43×80 = 34.4 . . . . km
The girls will have traveled 34.4 km when they meet.

Select the solutions of the og equation
Answer:
[tex]\boxed{\textsf{ The value of x is }\bf{ \dfrac{-5\pm\sqrt{21}}{2}}.}[/tex]
Step-by-step explanation:
A quadratic equation is given to us and we need to find the Solutions of the quadratic equation . So the given equⁿ is ,
[tex]\sf\implies (x+4)^2 -3(x+4) -3 = 0 [/tex]
Firstly let's simpify the quadratic equation and then use the quadratic formula also known as " Shreedhacharya's Formula" .
Taking the given equation :-
[tex]\sf\implies (x+4)^2 -3(x+4) -3 = 0\\\\\sf\implies x^2 + 16 + 8x -3x -12 -3 = 0 \\\\\sf\implies x^2+5x +1 = 0 [/tex]
Now let's use the Quadratic formula ,
Quadratic Formula :-
[tex]\qquad\boxed{\boxed{ \sf x =\dfrac{ -b \pm \sqrt{ b^2-4ac}}{2a} }} [/tex]
With respect to Standard form ax² + bx + c form. Here a = 1 , b = 5 and c = 1 .
[tex]\sf\implies x = \dfrac{ -5\pm \sqrt{ (5)^2-4(1)(1)}}{2(1)} \\\\\sf\implies x = \dfrac{ -5 \pm \sqrt{ 25 -4 } }{2} \\\\\sf\implies \boxed{\pink{\sf x = \dfrac{-5+\sqrt{21}}{2}, \dfrac{-5-\sqrt{21}}{2} }}[/tex]

If h= n + 4, and if n = 7, what is h?
A)
3
B)
1
D)
12
What is h
Answer:
11
Step-by-step explanation:
If n=7, you would substitute n in the equation with 7.
h=7+4
h=11
Answer:
h=11
Step-by-step explanation:
h = n + 4
but n = 7
h = 7 + 4

It usually takes you 1 1/4 hours to get home. One day, traffic was slowed by bad weather and it took you 2 1/2 hours to get home. How much longer did it take you to get home with bad weather?
Answer:
1 1/4 more hours
Step-by-step explanation:
To find this, we must subtract 2 1/2, the time it takes you to get home with bad weather by 1 1/4, the amount it usually takes you to get home. We can make 2 1/2 into 2 2/4, and now we can subtract and get 1 1/4.

A number squared is just the number times itself.
[tex]n(n)=n^2[/tex]
Answer:
A number squared is a number to the power of 2 or the number times itself.
Step-by-step explanation:
Lets say you have a 4 to the 2nd that would mean that the 4 is multiplied by 4. Dont get the exponent confused as the number to multiply it as. Look at [tex]9^{2}[/tex] for example, you would multiply the number 9 2 times not 9 times 2 so it would be 9x9.

Which sentence is true?
All whole numbers are also natural numbers.
b All integers are also rational numbers.
All rational numbers are also integers.
d. All integers are also whole numbers.
Answer:
Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you usually count and they will continue on into infinity.
Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4…
Integers include all whole numbers and their negative counterpart e.g. …-4, -3, -2, -1, 0,1, 2, 3, 4,…
All integers belong to the rational numbers. A rational number is a number
ab,b≠0
Where a and b are both integers.
Example
The number 4 is an integer as well as a rational number. As it can be written without a decimal component it belongs to the integers. It is a rational number because it can be written as:
41
or
82
or even
−8−2
Whereas
15=0.2
is a rational number but not an integer.
A rational number written in a decimal form can either be terminating as in:
15=0.2
Or repeating as in
56=0.83333...
All rational numbers belong to the real numbers.
If you look at a numeral line
picture05
You notice that all integers, as well as all rational numbers, are at a specific distance from 0. This distance between a number x and 0 is called a number's absolute value. It is shown with the symbol
|x|
If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites. Opposites have the same absolute value since they are both at the same distance from 0.
|10|=10=|−10|

How much money did Sandy get from her brother?
a) Write an equation for this scenario
b) Solve the scenario and find out how much money Sandy got from her brother
Answer:
Sandy got (approximately) $222.22 from her brother.
Step-by-step explanation:
