Padma cycles 3 1/4 miles. Josh cycles 7/2 miles. How far have they cycled in total? Give your answer as a mixed number. show your working.
Answer: 6 3/4 miles
Explanation: turn 3 1/4 into an improper fraction makeing it 13/4 multiply both 7 and 2 by 2 makeing 7/2 into 14/4 add the two together 13/4+14/4= 27/4 then simplify down to 6 3/4
They cycled in total 6 3/4 miles.
What is mean by Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
Padma cycles 3 1/4 miles.
And, Josh cycles 7/2 miles.
Now,
Since, Padma cycles 3 1/4 miles. Josh cycles 7/2 miles.
Hence, The total cycled by both = 3 1/4 + 7/2
= 13/4 + 7/2
= 13/4 + 14/4
= (13 + 14) / 4
= 27/4
= 6 3/4 miles
Thus, They cycled in total 6 3/4 miles.

To solve this, we have to solve for h.
We can use order of operations to figure this one out.
[tex]18h-9h-7h+3=17\\18h-9h-7h=14[/tex]
Now that every variable on the left side of the equation has an h, we can factor.

State the number of possible real zeros and turning points of f(x) = x7 – 6x6 + 8x5. Then determine all of the real zeros by factoring.
=
Answer:
steps below
Step-by-step explanation:
f(x) = x⁷ – 6x⁶ + 8x⁵
f'(x) = 7x⁶ - 36x⁵ + 40x⁴
= x⁴ (7x² - 36x + 40) ... (1)
Critical point (x,y): x = 0 , x = (36 ± √(-36)²-4*7*40) / (2*7) = (18±2√11) / 7
x = 0 or x = 3.5 or x = 1.6
plug into (1): y = 0 , y = -394.3 , y = 10.1
extreme : maximum (1.6 , 10.1) minimum (3.5 , -394.3) ... turning points
x⁷ – 6x⁶ + 8x⁵ = x⁵ (x² - 6x + 8) = x⁵ (x-2) (x-4) =0
real zeros: x = 0, x=2, x=4

Find a value for x that will make each of the following equations true. 2. x+8=21 b. 8-32=55 c. 3x=54 d. x/5=10 all I need help with is c
Answer:
C. x = 18
Step-by-step explanation:
3x = 54
First, you try to get x by itself.
To do that, you divide both sides by 3
It looks like this:
3x/3 = 54/3
And it ends up being:
x = 18
Answer:
x + 8 =21; x = 21 -8; x= 13
3x = 54; x =54/3;x= 18
x/5 = 10;x= 10× 5;x= 50

Find the number of ordered pairs (m,n) which satisfy the system
4(m - n) &= 7(1 - n),
3/2n= 4-2m.
If there are infinitely many such pairs, enter the word infinite.
There are no solutions to this system.
==========================================================
Explanation:
Let's simplify and rearrange terms for the first equation. The goal is to get it into the form Am+Bn = C, where A,B,C are constants.
4(m-n) = 7(1-n)
4m-4n = 7-7n
4m-4n+7n = 7
4m+3n = 7
Let's do the same for the second equation
(3/2)n = 4 - 2m
3n = 2(4-2m)
3n = 8 - 4m
4m+3n = 8
------------------------
The result of each simplification is that we ended up with 4m+3n on the left hand side for each equation. The only difference is that we got 7 for the first equation and 8 for the next one.
This is a contradiction because 4m+3n can only equal one number at a time for any given (m,n) pair. It's like saying z = 7 and z = 8 at the same time, where z = 4m+3n. But z can only equal one value at a time.
-------------------------
In summary, the given system leads to a contradiction and the system is inconsistent. This means that there are no solutions. There are 0 ordered pairs (m,n) that make both original equations to be true.
The correct answer is there is exactly one ordered pair ([tex]m = \dfrac{73}{56}[/tex] , [tex]n = \dfrac{13}{14}[/tex] ) that satisfies the given system of equations.
Given
[tex]4(m - n) = 7(1 - n)[/tex]
[tex]\dfrac{3}{2} n = 4 - 2m[/tex]
First, simplify the second equation:
[tex]\dfrac{3}{2} n +2m = 4[/tex]
Now, solve this equation for n:
[tex]n = (4 - 2m) * \dfrac{2}{3}[/tex]
[tex]n = \dfrac{(8 - 4m)}{3}[/tex]
Now, substitute this value of n into the equation [tex]4(m - n) = 7(1 - n)[/tex] :
[tex]4(m - \dfrac{(8 - 4m)}{3}) = 7(1 - \dfrac{(8 - 4m)}{3}[/tex]
[tex]m = \dfrac{73}{56}[/tex]
From the value of m, substitute it back into the equation for n:
[tex]n = \dfrac{(8 - 4m)} { 3}[/tex]
[tex]n = \dfrac{13}{14}[/tex]
The solution is one ordered pair [tex]m = \dfrac{73}{56}[/tex] and [tex]n = \dfrac{13}{14}[/tex].

Answer:
Zuri: -10x + 125, Cara: 10x+125, Julio: 125x + 10
Step-by-step explanation:
Zuri starts with 125 dollars, and spending 10 dollars per month, means a subtraction of $10 per month. So, after x months, the subtraction = -10x = -10 + -10 + ... + -10, x times. Thus, f(x) = 125 + (- 10x) = 125 - 10x = -10x + 125.
Cara starts with 125 coins, and collecting 10 coins per year, means an addition of 10 coins per year. So, after x years, the addition = 10x = 10 + 10 + ... + 10, x times. Thus, f(x) = 125 + 10x = 10x + 125.
Julio starts with $10, and earning $125 per week, means an addition of $125 per week. So, after x weeks, the addition = 125x = 125 + 125 + ... + 125, x times. Thus, f(x) = 10 + 125x = 125x + 10.

work out the percentage change when a price of £70 is decreased to £49
Answer:
30% decrease in price
Step-by-step explanation:
Since 70-49=21, we know that the price decreased by 30 pounds. The formula to find a percentage decrease is that you should then divide the original number(70) by 21(that equals 0.3!) 0.3 as a percentage would then be 30%, so the answer is there is a 30% decrease in price.
