Answer:
x=3/4 as fraction form.
x=0.75 as decimal form.
Step-by-step explanation:
Step 1.
2x2-12x+8=3
2x2=4
Step 2.
4-12x+8=3
4+8=12
12-12x=3
Step 3.
12-12x=3
(Subtract 12 from both sides.)
-12x=3-12
-12x=-9
Step 4.
-12x=-9 will equal:
0.75 or 3/4
But rounded up will equal 1 whole.
I hope this helps. :)
Nella travelled 1/3 of a journey by bus, 2/3 of the remainder by bicycle and the remaining 9 km on foot. a)How far did Nella cycle? b)What was the total distance that Nella travelled?
Answer:
18km
40.5km
Step-by-step explanation:
Let b = journey by bus
c = journey by bicycle
d = total journey
c = (2/3 x d) x 2/3
divide both sides by 2/s
c(3/2) = (2/3)d
c + 9km = 2/3d
c + 9km = 3/2 c
collect like terms and solve for c
3/2c - c = 9km
1/2c = 9km
c = 18km
2. IF cycling (18km) and walking (9km) make up 2/3 of the journey, 2/3 of the journey is 27km
2/3d = 27km
divide both sides by 3/2 to find d
d = 40.50 km

do 18/14 and 10/15 have the same vaule explain why
Answer:
Step-by-step explanation:
18/14 and 10/15 don't have the same value. Only equivalent fractions have same value.
These two are not equivalent fractions
Answer:
No.
Step-by-step explanation:
Without much calculation, we can notice that 18/14 is actually greater than 10/15 since its numerator is greater than its denominator, making it greater than 1. However, 10/15 is less than 18/14 since its numerator is less than its denominator making it less than 1. In short:
18/14 > 1
10/15 < 1
18/14 > 10/15
Peter Piper Plumbing charges $7.50 per hour for labor

company charges you $76.50 for a house call, how
many hours were they at your house? Write an equation
and solve.
What is the sum of -64/5 and 64/5 ?
Answer and Explanation
0This is because they are both the same opposite number, and you are adding.
But, if it was, [tex]\frac{64}{5}+\frac{64}{5}[/tex] then it would be [tex]25.6[/tex] or [tex]\frac{128}{5}[/tex].
So, the answer is 0.
Hope this helps =)

Solve the inequality. 3/4x−2/3≤5/6 Choose the solution that is graphed on this number line.
Answer:
x ≤ 2
(when graphed, closed circle on two, shaded to the left)
Step-by-step explanation:
3/4 x - 2/3 ≤ 5/6
Add 2/3 to both sides:
3/4x ≤ 5/6 + 2/3
3/4x ≤ 3/2
Divide by 3/4 on both sides:
x ≤ 3/2 ÷ 3/4
x ≤ 2

10. Solve for all values of x algebraically (find the zeroes):
3x^2 +12x – 7 = x^2+ 3x – 2
Answer:
x = -5 or 1/2
Step-by-step explanation:
From the question,
3x²+12x-7 = x²+3x-2
Collect like terms
3x²-x²+12x-3x-7+2 = 0
2x²+9x-5 = 0
Using factorization method to solve the quadratic equation
2x²+10x-x-5 = 0
(2x²+10x)-(x+5) = 0
2x(x+5)-1(x+5) = 0
(x+5)(2x-1) = 0
Either,
x+5 = 0
x = -5
or,
2x-1 = 0
2x = 1
x = 1/2.
Therefore,
x = -5 or 1/2

Ramon earns $1670 each month and pays $53.00 on electricity. To the nearest tenth of a percent, what percent of Ramon's earnings are spent on electricity each month?
Answer:
the percentage of the ramon earnings spent on electricity is 3.17%
Step-by-step explanation:
The computation of the percentage of the ramon earnings spent on electricity is shown below:
= Pays for electricity ÷ earnings per month
= $53 ÷ $1,670
= 3.17%
Hence, the percentage of the ramon earnings spent on electricity is 3.17%
Nike and Adidas are having a huge sale for the next 5 days. Create a graph to determine if the shirts and cost are proportional.
A) Is the number oft-shirts proportional to the cost?
B) Write an equation to illustrate the relationship between the number of t-shirts and cost?
C) Using the equations predict the cost of 20 shirts sold.
D) 1%at docs the point (5, 35) represent in the context ofthc situation pertaining to Nike?
E) Which company has the better cost per shirt?
Answer:
See the graph with both lines attached
A) From the tables we see the constant change of values in the second column and the initial value is zero.
This represents a proportional relationship.B) Rate of change is 7 per shirt, the equation is:
y = 7x, where y is cost, x - is the number of shirtsC) When x = 20,
y = 7*20 = 140Cost of 20 shirts is $140D) The point (5, 35) represents that:
The cost of 5 shirts is $35E) The second table has confusing titles (not about the number or cost of shirts) but if we assume its same as the first table, then Adidas has greater price of $8 per shirt.
Comparing the prices, Nike has better cost
price of $8 per shirt.
Comparing the prices, Nike has better cost

What is the surface area of the box if it is scaled up by a factor of 10?
the surface area is 206 in, width 9 in, length 13 in, height 4 in
(first to answer gets brainly please need answer quick!)
Answer:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in
