This week, Ariel ended up needing 12 gallons of gas. That is 20% more than she needed last
week. How much gas did Ariel need last week?
Answer:
10 gallons
Step-by-step explanation:
She used 12 gallons this week and used 20% more than last week. That means 12 gallons is 120% of last weeks gas. Since 12 times 10 equals 120, then to find 20% you do 20 divided 10 and subtract the answer from 12.
20% is 2 because 20 divided by 10 is 2. 12 minus 2 is 10

Julio believes that the quotient of 6 divided by 1/2 = 3. Explain Julios error and tell how to find the correct answer.
Answer:
it can be written as 6/1 divided by 1/2
then you'll use the keep, switch, flip method. keep 6/1, switch division to multiplication, and flip 1/2 to become 2/1 or 2
now your equation is 6 x 2 = 12
Julio did 6 divided by 2. which could've been fixed if he changed the division sign to multiplication and multiplied
Type the correct answer in each box. If necessary, use / for the fraction bar(s).
Find the solution for this system of equations.
12x + 15y = 34
-6x + 5y = 3
x =
y =
Answer:X=5/6 Y=8/5
Step-by-step explanation:
-6x +5y=3
+6x
5y=6x+3 (divide each number by 5)
Y=6/5x + 3/5 (Plug that into your x equation)
12x+15 (6/5x + 3/5) =34
(Multiply 15 by the numbers in the brackets you can break it down and do 15•6 divided by 5 )
15•6=90 divided by 5=18x
15•3= 45 divided by 5=9
(Add like variables)
12x+18x=30x
30x+9=34
(Subtract 9 from itself do the same to 34)
9-9= 0
34-9=25
Divide 30 by itself to get x by itself then divide 25 by 30
25 divided by 30= 5/6
X=5/6 (plug that into the y equation)
Y=6/5•5/6+3/5
Multiply 6/5 and 5/6 straight across because this is multiplication you don't need like denominators
6/5•5/6=30/30=1
Y=1+3/5
1/1 + 3/5
Here you need to have like denominators because it is addition so just use 5
5•1=5
5/5+3/5=8/5
Y=8/5
Answer:
The value of x is 5/6 and y is 8/5.

2 years ago, age of brother was 3 times less than sister's age. this year his age is just 2 times less than his sister's. how old is brother? how old is sister?
Answer:
[tex]The\ brother's\ present\ age= 4\ years\\The\ sister's\ present\ age=8\ years[/tex]
Step-by-step explanation:
[tex]Let\ the\ brother's\ present\ age\ be\ x\\Hence\ we\ are\ given,\\His\ sister's\ present\ age=(2x)\\Now,\\The\ brother's\ age\ before\ two\ years=(x-2)\\The\ sister's\ age\ before\ two\ years=3(x-2)\\Also,\\His\ sisters\ age\ before\ two\ years=2x-2\\Hence,\\3(x-2)=2x-2\\3x-6=2x-2\\3x-2x=6-2\\x=4\\Hence,\\The\ brother's\ present\ age= 4\ years\\The\ sister's\ present\ age=2x=2*4=8\ years[/tex]
Answer:
The sister's present age is 8 years old, and the brother's present age is 4 years old.
Step-by-step explanation:
Let [tex]b =[/tex] present age of the brother, [tex]s =[/tex] present age of the sister
[tex]s-2 = (b-2)[/tex] × [tex]3[/tex]
[tex]s-2[/tex] = [tex]3b - 6[/tex]
[tex]s = 3b - 4[/tex]
[tex]s = b[/tex] × [tex]2[/tex]
[tex]= 2b[/tex]
[tex]sb-4 = 2b[/tex] (proved from above equations)
[tex]b = 4[/tex]
[tex]\because s = 3b - 4[/tex]
[tex]\therefore[/tex][tex]s = 3[/tex]×[tex]4 - 4[/tex]
[tex]= 8[/tex]
[tex]\therefore[/tex] the brother's present age is 4 years old, and the sister's present age is 8 years old.

What is the slope of the line parallel to y=2/5x-1?
I really need help with this fast please
Answer:
The slope will be 2/5.
Step-by-step explanation:
[tex]y = 2/5x -1[/tex] is written in slope-intercept form.
This formula looks like:
[tex]y=mx+b[/tex]
where:
M = Slope x = independent variableb = y-interceptSo:
[tex]2/5[/tex] is our slope[tex]x[/tex] remains our independent variable[tex]-1[/tex] is our y-intercept.1 ). For two lines to be parallel they must have the same slope.
Slope would remain 2/52 ). For two line to be perpendicular they must have slopes that are opposite reciprocals.
. Slope would become -5/2As the question states, we must find the slope of a line parallel to the equation given. This means that the slope will remain 2/5.
Lets check our work!
Choose a random ordered pair. I will choose (5, 6).
Now, using point slope-form we can find out if what was said above is true!
This formula looks like:
[tex]y - y1 = m (x-x1)[/tex]
Let us substitute:
[tex]y - 6 = 2/5(x-5)[/tex]
Distribute:
[tex]y-6=2/5x-2[/tex]
Add 6 to both sides:
[tex]y= 2/5x+4[/tex]
Now using both equations I will plot them on a graph to see if they a parallel.
As you can see from the graph below, these lines are parallel. Where the equation you were given is in blue and the equation I made is in red.
Based on all of the evidence, the slope will be 2/5.
Hope this helped! :)

How many lines are determined by the points a b c d and e if 3 of them arent collinear
Answer:
10 possible lines
Step-by-step explanation:
Given
[tex]Points = \{a,b,c,d,e\}[/tex]
Required
Number of lines
From the question, the number of points (n) are:
[tex]n = 5[/tex]
If 3 points are not collinear (i.e. on a straight line), it means that only (5 - 3) of the points can be chosen
So, we have:
[tex]n = 5[/tex]
[tex]r = 5 - 3[/tex]
[tex]r =2[/tex]
The number of lines is then calculated using combination formula.
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
We used combination because the analysis done above implies that 2 points are to be selected from a,b,c,d and e.
To select means combination
Having said that;
Substitute [tex]5\ for\ n\ and\ 2\ for\ r[/tex]
[tex]^5C_2 = \frac{5!}{(5-2)!2!}[/tex]
[tex]^5C_2 = \frac{5!}{3!2!}[/tex]
[tex]^5C_2 = \frac{5*4*3!}{3!2!}[/tex]
[tex]^5C_2 = \frac{5*4}{2!}[/tex]
[tex]^5C_2 = \frac{5*4}{2*1}[/tex]
[tex]^5C_2 = \frac{20}{2}[/tex]
[tex]^5C_2 = 10[/tex]
Hence, there are 10 possible lines

Answer:
114
Step-by-step explanation:
(400/4)+(40/4)+(16/4)
400/4=100
40/4=10
16/4=4
100+10+4=114
Answer:
all 4 for the top
456 / 4 = 114
Step-by-step explanation:
if you add up 400, 40, and 16, then you have 456. So basically if you divide them all by 4, the answer of all those numbers will equal 114

Parallelogram LMNO has the coordinates L(1, 4), M(7, 4), N(6, 0) and O(0, 0). The diagonals of Parallelogram LMNO intersect at point P. What are the coordinates of point P?
Answer:
[tex]P(x,y) = (\frac{7}{2},2)[/tex]
Step-by-step explanation:
Given
Parallelogram LMNO
[tex]L = (1,4)[/tex]
[tex]M = (7,4)[/tex]
[tex]N = (6,0)[/tex]
[tex]O = (0,0)[/tex]
Required
Determine the point of intersection
The point of intersection of the diagonal is the midpoint of the parallelogram.
The diagonals are: LN and MO
Calculating midpoint, P of LN
[tex]P(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
Where
[tex]L = (1,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]N = (6,0)[/tex] --- [tex](x_2,y_2)[/tex]
So:
[tex]P(x,y) = (\frac{1 + 6}{2},\frac{0 + 4}{2})[/tex]
[tex]P(x,y) = (\frac{7}{2},\frac{4}{2})[/tex]
[tex]P(x,y) = (\frac{7}{2},2)[/tex]
To confirm, we make use of diagonals MO
[tex]M = (7,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]O = (0,0)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]P(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
[tex]P(x,y) = (\frac{7 + 0}{2} , \frac{4 + 0}{2})[/tex]
[tex]P(x,y) = (\frac{7}{2} , \frac{4}{2})[/tex]
[tex]P(x,y) = (\frac{7}{2},2)[/tex]
Hence, the coordinates of the intersection, P is [tex](\frac{7}{2},2)[/tex]
