Car A travels 20 mph faster than Car B. In the same time that Car A travels 208 mi, Car B travels 156 mi. Find their speeds. The speed of Car A is and the speed of Car B
Step-by-step explanation:
Assuming the speed of car B to be x and the speed of car A to be x+20
156 = 208
x. x+20
156(x+20)= 208x
156x+3120=208x
3120=208x-156x
3120=52x
x=60
The speed of car A is (x)= 60
The speed of car B is(x+20)= 80
Answer:
[tex]\huge\colorbox{red}{Car\: A=80}\colorbox{blue}{Car B=60}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:equationPEMDASlet's solve:let the speed of car A be A
let the speed of car B be B
according to the first condition:
[tex]\quad A=B+20[/tex]
according to the second condition:

Megan considers two different car rental options. One option costs $19 per day plus $0.12 per kilometre. Another option costs $42.50 per day for unlimited kilometres.
Compare the two options for a one-day rental. Which option should Megan choose? Why?
Give me answer in full explanation please!
Answer:
The $19 car
Step-by-step explanation:
For a one day rental I'd say its pretty average to only be driving for about 160km which is about 100 miles. For those 160km you would only be paying $19. The combined total $38, which is still less than the $42.50 car. The only way this would somewhat equal out is if you drove 200km or 124 miles. That would make the total cost exactly $43. If Meghan plans on driving equal to or more than 200km then she should choose the $42.50 car. In my opinion the $19 should be enough for 1 day.

Im having a brain fart moment rn. Does f(27) mean to replace the x with 27 or f(x) with 27
Answer:
it means replace x with 27
Step-by-step explanation:
[tex] \sqrt[3]{27 + 98} + 5 = \sqrt[3]{125} + 5 = 5 + 5 = 10[/tex]
Answer:
10
Step-by-step explanation:
f(27) means to replace the x, not f(x). This means the equation would be [tex]f(27)=\sqrt[3]{27+98}+5[/tex]. First, take the cube root of 27 + 98 (125), which equals 5. Then add this to the 5 on the outside of the cube root to get 10.

4x+y=-1
-5x-2y=-4
Answer: ( -2, 7 )
Step-by-step explanation:
Solve 4x + y = -1 for y:
Add -4 to both sides:
4x + y + -4 = -1 + -4
y = -4x - 1
Now plug -4x -1 in the other equation with y:
-5x - 2 ( -4x -1 ) = -4
3x + 2 = -4
Add -2 to both sides:
3x + 2 - 2 = -4 + -2
3x = -6
Now divide both by 3:
3x/3 = -6/3
x = -2
Now plug in -2 in the first equation with x:
y = - 4 ( -2 ) - 1
y = 7
A perfect square is the product of any positive whole number used as a factor exactly two times. [Example: 49 is a perfect square because 7 × 7 = 49] The positive whole number N, when multiplied by 150, is a perfect square. What is the least possible positive whole number value for the number N?
A perfect square can be defined as a number that can be expressed as the product of an integer by itself or as the second exponent of an integer.
The value of N for the given question is 6.
To reach the above solution we need following steps:
Given:
[tex]\rm 150\times N = Perfect\:square[/tex]
Since 150 is not a perfect square N is not equals to 1.
Putting values starting from 2 on the place of N.
[tex]150\times2 = 300\\\\150 \times3=450\\\\150\times4= 600\\\\150\times5= 750\\\\150\times6=900[/tex]
Since 900 is a perfect square, the value of N will be 6.
