-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]

∠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°

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

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]
If the original quantity is 5 and the new quantity is 4, what is the percent decrease?
Answer:
try using percent decrease calculator
Step-by-step explanation:
maybe that'll help
Answer:
The answer is 20%
Step-by-step explanation:
5=100%
meaning if you decrease it by one each time it will look like this:
5=100%
4=80%
3=60%
2=40%
1=20%
so if it was decreased to four your answer is 20%
and you still have 80% remaining.

12а + 7x - За – 2х what's the answer
2/3x =36
Possible answers
+24
-24
+54
-54
Answer:
[tex]+54[/tex]
Step-by-step explanation:
To solve this, you will need inverse operations to isolate the x. Since x is multiplied by 2/3, you want to divide it by 2/3. Since we always have to do the same thing to both sides, we will also divide 36 by 2/3.
[tex]\frac{2}{3}x = 36\\\\$\scriptsize{\div2/3\;\; \div2/3}\\[/tex]
[tex]\frac{2}{3} x \; \div \; \frac{2}{3} = x[/tex]
([tex]\frac{2}{3}[/tex] cancels out)
[tex]\frac{36}{2/3} = 54[/tex]
[tex]x = 54[/tex]

A large shipment of light bulbs has just arrived at a store. It has been revealed that 17 % of the light bulbs are defective (the other light bulbs are good). Suppose that you choose 6 light bulbs at random. What is the probability that 2 or less of the bulbs are defective.?
Answer:
The required probability = 0.9345
Step-by-step explanation:
Given that:
p = 0.17
n = 6
The required probability that two or less light bulbs are defective = (P<2)
(P<2) = P(X=0) +P(X=1) +P(X=2)
[tex](P<2) =\bigg [ ({^6C_0}\times 0.17^0 \times (1-0.17)^{6-0})+ ({^6C_1}\times 0.17^1 \times (1-0.17)^{6-1}) +( {^6C_2}\times 0.17^2 \times (1-0.17)^{6-2}) \bigg ][/tex]
[tex](P<2) =\bigg [ \dfrac{6!}{0!(6-0)!}\times 0.17^0 \times (1-0.17)^{6})+ (\dfrac{6!}{1!(6-1)!} \times 0.17^1 \times (1-0.17)^{5}) +( \dfrac{6!}{2!(6-2)! }\times 0.17^2 \times (1-0.17)^{4}) \bigg ][/tex]

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

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

What is the slope of the line
through (2, 10) and (-2, 17)?
Answer:
The answer is
[tex] \huge - \frac{7}{4} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
From the question we have
[tex]m = \frac{17 - 10}{ - 2 - 2} = \frac{7}{ - 4} = - \frac{7}{4} \\ [/tex]
We have the final answer as
[tex] - \frac{7}{4} \\ [/tex]
