Answer:
5/3 = z
Step-by-step explanation:
You can use proportions to figure this out.
Imma solve this as I work through it.
So
4/z is equal to 12/5. So you can do something called the butterfly method (I have never used this before, but it works tho) and the method involves only multiplication and division.
Lemme clean this up for ya
The butterfly method involves multiplying in a cross format on both sides, so the
4 12
__ = ______
z 5
becomes 4 times 5, and z times 12.
4 times 5 is 20, and z times 12 is 12z
so you now have 20 = 12z
Lets simplify the equation by dividing by 4s
20 divided by 4 is 5 and 12z divided by 4 is 3z
so
5 = 3z
You can divide again
by dividing both sides
by
3
to get the unit rate of z.
It will be a fraction though
and it won't look pretty
but here it is:
5
__ = z
3
So
It is
5/3

20 people fit comfortably in a 9 feet by 10 feet area. Use this value to estimate the size of a crowd that is 7 feet deep on BOTH sides of the street along 1,500 inches of a parade route. Please show work c: Merci!
Answer:
389 people
Step-by-step explanation:
Step 1
we convert 1500 inches to feet
1 inch = 0.0833 feet
1500 inches = x feet
x = 1500 × 0.0833
x = 125 feet
Step 2
We create a proportion
Since it is on both sides
20/9ft × 10ft = x/7 feet × 125 feet × 2
20/90 = x/1750
Cross Multiply
90 × x = 20 × 1750
x = 20 × 1750/90
x = 35000/90
x = 388.88888889
approximately = 389 people

write 4x-8=9y-5 in standard form
Answer:
4x - 9y = 3
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
4x - 8 = 9y - 5 ( subtract 9y from both sides )
4x - 9y - 8 = - 5 ( add 8 to both sides )
4x - 9y = 3 ← in standard form

List 3 rational numbers between -5/13 and 1/13
Plz help
Answer:
[tex]\displaystyle -\frac{4}{13},~-\frac{3}{13},~-\frac{1}{13},~0[/tex]
Step-by-step explanation:
Rational Numbers
The rational numbers are defined as numbers of the form [tex]\frac{a}{b}[/tex] where a and b are integer numbers and b is not zero.
Two rational numbers expressed as fractions can be better compared if they have the same denominator. For example, 5/11 is greater than 3/11 because they have the same denominator and 5 is greater than 3.
Similarly, if we have the fractions -5/13 and 1/13, it's clear that the first fraction is less than the second. If we wanted to have some rational numbers between them we only have to play around with the numerators: any number between -5 and 1 will do.
Examples of the required numbers:
[tex]\displaystyle -\frac{4}{13},~-\frac{3}{13},~-\frac{1}{13},~0[/tex]

∠1 and ∠2 are vertical angles. If m∠2 = 124°, find the measure of the supplement of ∠1 plzzz i need help
Answer:
∠1 = 124 degrees
Step-by-step explanation:
Vertical angles are always congruent
So ∠1 = ∠2
Answer:
Supplement of m∠1 = 56°
Step-by-step explanation:
Since both angles are vertical, they both equal to each other.
m∠2 = m∠1
= 124°
To find the supplement of m∠1, we need to remember that supplementary angles add up to 180°.
Supplement of m∠1 = 180°-124°
= 56°

-3(u+2)=5u-1+5(2u+1)
Answer:
u = -5/9
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-3(u + 2) = 5u - 1 + 5(2u + 1)
Step 2: Solve for u
Distribute: -3u - 6 = 5u - 1 + 10u + 5Combine like terms: -3u - 6 = 15u + 4Add 3u to both sides: -6 = 18u + 4Subtract 4 on both sides: -10 = 18uDivide 18 on both sides: -10/18 = uSimplify: -5/9 = uRewrite: u = -5/9Step 3: Check
Plug in u into the original equation to verify it's a solution.
Substitute in u: -3(-5/9 + 2) = 5(-5/9) - 1 + 5(2(-5/9) + 1)Multiply: -3(-5/9 + 2) = -25/9 - 1 + 5(-10/9 + 1)Add: -3(13/9) = -25/9 - 1 + 5(-1/9)Multiply: -13/3 = -25/9 - 1 - 5/9Subtract: -13/3 = -34/9 - 5/9Subtract: -13/3 = -13/3Here we see that -13/3 does indeed equal -13/3.
∴ u = -5/9 is a solution of the equation.
Answer:
[tex] \sf u = -\dfrac{5}{9} [/tex]
Step-by-step explanation:
Expand the following:
[tex] \longrightarrow [/tex] -3(u + 2) = 5u - 1 + 5(2u + 1)
5(2u + 1) = 10u + 5:
[tex] \longrightarrow [/tex] -3(u + 2) = 5u - 1 + 10u + 5
-3(u + 2) = -3u - 6:
[tex] \longrightarrow [/tex] -3u - 6= 10 u + 5 u - 1 + 5
Grouping like terms,
5u - 1 + 10u + 5 = (5u + 10u) + (-1 + 5):
[tex] \longrightarrow [/tex] -3u - 6 = (5u + 10u) + (-1 + 5)
5u + 10u = 15u:
[tex] \longrightarrow [/tex] -3u - 6 = 15u + (-1 + 5)
5 - 1 = 4:
[tex] \longrightarrow [/tex] -3u - 6 = 15u + 4
Subtract 15 u from both sides:
[tex] \longrightarrow [/tex] (-3u - 15u) - 6 = (15u - 15u) + 4
-3u - 15u = -18u:
[tex] \longrightarrow [/tex] -18u - 6 = (15u - 15u) + 4
15u - 15u = 0:
[tex] \longrightarrow [/tex] -18u - 6 = 4
Add 6 to both sides:
[tex] \longrightarrow [/tex] (6 - 6) - 18u = 6 + 4
6 - 6 = 0:
[tex] \longrightarrow [/tex] -18u = 4 + 6
4 + 6 = 10:
[tex] \longrightarrow [/tex] -18u = 10
Divide both sides of -18 u = 10 by -18:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{-18u}{-18}= \dfrac{10}{-18} [/tex]
[tex] \sf \dfrac{-18}{-18}=1: [/tex]
[tex] \longrightarrow [/tex] [tex] \sf u = \dfrac{10}{-18} [/tex]
[tex] \sf \dfrac{10}{-18}=\dfrac{5}{-9}: [/tex]
[tex] \longrightarrow [/tex] [tex] \sf u = \dfrac{5}{-9} [/tex]
Multiply numerator and denominator of [tex] \sf \dfrac{10}{-18} [/tex] by -1:
[tex] \longrightarrow [/tex] [tex] \sf u = \dfrac{-5}{9} [/tex]

An angle measures 20° less than the measure of its complementary angle. What is the measure of each angle
Answer:
The angle measure is 35°.
Step-by-step explanation:
Complementary angles in geometry are angles that summate to exactly 90 degrees. If an angle measures 20 degrees less than the measure of its complementary angle, we can create an equation to find the measure of this angle.
The complementary angle is going to equal 90 - x, so this becomes a term in our equation: (90 - x)
Both angles need to add up to 90 degrees, so we can set up this equation:
x = (90 - x) - 20, where x is our unknown angle.
Now, we can just solve for x.
[tex]x = (90-x)-20\\\\x = 90 - x - 20\\\\x = 70 - x \\\\2x = 70\\\\\bold{x = 35}[/tex]
Therefore, the angle that measures 20 degrees less than its complementary angle is 35°. We can check this by using substitution:
[tex]90 = x + 35\\\\55 = x \rightarrow x = 55\\\\55 - 35 = 20[/tex]
Therefore, the two angles are 55° and 35°, but the angle that measures 20° less than the measure of its complementary angle is 35°.
what is the value of B and C
Answer:
The value of b is 6 and the value of c is also 6
Step-by-step explanation:
We know that given triangles are congruent. When two triangles are congruent then their respective sides are also equal/congruent.
So,
ΔUWV≅ΔEDF
Then
WV ≅ DF
WU ≅ DE
UV ≅ EF
So,
Putting their respective value equal:
WV = DF
[tex]9c = 10c-6\\10c-6 = 9c\\10c-6+6 = 9c+6\\10c = 9c+6\\10c-9c = 9c+6-9c\\c = 6\\and\\10b = b+54\\10b-b = b+54-b\\9b = 54\\\frac{9b}{9} = \frac{54}{9}\\b = 6[/tex]
Hence,
The value of b is 6 and the value of c is also 6

Choose one item to purchase. What is the greatest number of that item you can buy with a $10 bill and still receive change? How much change will you receive ? Explain.
Answer:
poster board
Step-by-step explanation:
2Conditions:
-greatest number of 1 item
-still receive change
If you go for the cheapest items like pencil or eraser you will pay with $10 for
$0.10* 100items= $10 yet no change
If you go for second most cheapest pen $0.25 you can by
if you buy 4 pencils and each with $0.25 you will pay $1
for $ 10 you can get 4*10 = 40 pencils yet no change
if you go for the third cheapest item is the poster board
$ 1.50*2= $3 so $1.50*6 =$9 and the change will be $10-9$ = $1
