Answer
-6
Step-by-step explanation:
3x-12=-2x-42
(Collect like terms together:)
3x+2x=-42+12
(when the number crosses the equal sign it changes signs)
5x/5=-30/5
(We devided by 5 cause we looking for x not 5x)

Answer:
12
Step-by-step explanation:
Area of triangle + area of square + area of triangle = total area
(Area of a triangle: A = 1/2bh)
(Area of a square: A = bh)
Area of smallest triangle =
A = 1/2 (2) (2) = 2
Area of largest triangle=
A = 1/2 (2) (6) = 6
Area of the square =
A = 2 x 2 = 4
Total shape:
2 + 4 + 6 = 12

Answer:
C= 93⁰, B= 64⁰, D= 23⁰
Step-by-step explanation:
180= (4x + 1) + (3x - 5) + x⁰
180= 4x+1 +3x-5 +x
180= 8x - 4
184= 8x
184/8= x
23=x
therefore
C= (4(23) +1)
C= 93
B= (3(23)-5)
B= 64
D= 23
93⁰+64⁰+23⁰=180⁰

How many liter of 15% weed killer mixture must be added to 5 liters of 10% weedkiller mixture to make 12% weed killer mixture?
Answer: 3 1/3 liter
Brainliest? <3
let x equal the number of liters of 15% weedkiller.
your equation is .15 * x + .10 * 5 = .12 * (x + 5)
simplify to get .15 * x + .10 * 5 = .12 * x + .12 * 5
simplify further to get .15 * x + .5 = .12 * x + .6
subtract .12 * x from both sides and subtract .5 from both sides and simplify to get .03 * x = .1
divide both sides by .03 to get x = .1 / .03 = 3.333333333 rounded to 9 decimal digits.
you would need 3.333333333 liters of 15% solution to be added to 5 liters of 10% solution to get 8.333333333 liters of 12% solution.
.15 * 3.333333333 = .5
.10 * 5 = .5
.5 + .5 = 1
5 + 3.333333333 = 8.333333333
1 divided by 8.333333333 = .12 which is equal to 12%.
which number is correct
Answer:
5
Step-by-step explanation:
Side QR is equal to PS.
QR = 2x + 3
PS = 4x - 7
Since both sides are equal, here is the equation:
2x + 3 = 4x - 7
x = 5

A scientist measured the wavelength of an orange light wave as 0.000000615 meters.
A second scientist measured the wavelength of a green light wave as 5.6 x 10-7 meters.
How much longer, in meters, was the orange light wave than the green light wave?
Answer:
it 5.5⋅10−^8m
Step-by-step explanation:
Unless I'm missing something important here, you can find the difference between the two wavelengths by subtracting one from the other. Since you're interested in finding how much longer the wavelength associated with the orange light is, subtract the wavelength of the green light from the wavelength of the orange light. You know that the two measured wavelengths are 6.15 ⋅ 10 − 7 m → orange light 5.6 ⋅ 10 − 7 m → green light Therefore, the difference between the two wavelengths will be Δ wavelength = 6.15 ⋅ 10 − 7 m − 5.6 ⋅ 10 − 7 m = 5.5 ⋅ 10 − 8 m

Write the equation of a line through the point (5,4) that is perpendicular to the line y=-5/3x-2
Answer:
y=3/5x+1 because when a line is perpendicular to another line the slope it the opposite meaning negative to positive or positive to negative
you also reverse the number/ fraction...for example, if the slope was 2 the slope in the other equation would be -1/2. if the slope in the first equation was 1/2 the second equation slope would be -2 since it is the opposite and flipped

Answer: What do u need help with?
Step-by-step explanation:
write as
single fraction:
2/3a - 1/b + 3/2ab
Answer:
(4b - 6a + 9) / 6ab.
Step-by-step explanation:
The lowest common denominator of 3a, b and 2ab = 6ab
Now to get the numerator we divide each of the 3 denominators into 6ab and multiply the result by the corresponding numerator:
So we have:
2/3a - 1/b + 3/2ab
= (2*2b - 6a +3*3) / 6ab
= (4b - 6a + 9) / 6ab.
You have a roll of 100 feet of tubing and you need to cut 8 ½ foot lengths for IV pumps. How many 8 ½ foot lengths will you get? Will there be any tubing left over? If so, how much?
Answer: 11, 6.5 ft
Step-by-step explanation:
Given
The length of the roll is [tex]100\ ft[/tex]
The length required for a pump is [tex]8\ \frac{1}{2}\ ft=\frac{17}{2}\ ft[/tex]
No of pumps(n) we get
[tex]\Rightarrow \dfrac{100}{\frac{17}{2}}=11.76\ \approx 11[/tex]
length for 11 pumps
[tex]\Rightarrow 11\times \frac{17}{2}=93.5\ ft[/tex]
The remaining length of the tube is
[tex]\Rightarrow 100-93.5=6.5\ ft[/tex]

In early 2016 there were about 80 devil's line ving on the maria island of the total of 75% are offspring from the previous two breeding seasons how many are offspring
Answer: 60 devil offspring.
Step-by-step explanation:
The total number of devils in the Island is 80.
Out of this 80, 75% are offspring from the two previous breeding seasons.
This percentage in a whole number is what the question requires.
The number of offspring from previous seasons is:
= Percent of offspring from previous seasons * Total number of devils
= 75% * 80
= 60 devil offspring.

Amanda slept for 1/3 of the day. She played with her friends for 1/5 of the day. She spent the rest of the day working on a school project. What fraction of the day did she spend working on her project?
Answer:
She spent 7/15 of the day working on her project.
Step-by-step explanation:
Well we cant get a clear answer with the fractions 1/3 and 1/5, so we are going to have to turn them into equivalent fractions.
3 and 5 both have 15 LCD so:
1/3 x 5/5 = 5/15
1/5 x 3/3 = 3/15
5/15 + 3/15 = 8/15
15/15 - 8/15 = 7/15
She spent 7/15 of the day working on her project.
Hopefully this helps :3 Sorry if wrong :( Plz mark brainiest if correct :D Your bootiful/handsome! Have a great day luv <3

Tonya is staring a jewelry business. She is going to sell b bracelets for $12.50 each and n necklaces for $22.50. Tonya wants to make at least $800 a month. Which inequality below models this situation? A 12.50n +22.50b≥80012.50n\ +22.50b\geq 80012.50n +22.50b≥800 B 12.50b+22.50n≤80012.50b+22.50n\leq 80012.50b+22.50n≤800 C 12.50b+22.50n≥80012.50b+22.50n\geq 80012.50b+22.50n≥800 D 12.50n+22.50b≤80012.50n+22.50b\leq 80012.50n+22.50b≤800
Answer:
C 12.50b+22.50n≥800
Step-by-step explanation:
Tonya is staring a jewelry business. She is going to sell b bracelets for $12.50 each and n necklaces for $22.50. Tonya wants to make at least $800 a month.
When we use the word at least in Mathematics is means that it is equal to or more than $800.
It is represented by the symbol ≥
Number of bracelets = b
Number of necklaces = n
Therefore, the inequality below models this situation is given as:
$12.50 × b + $22.50 × n ≥ $800
= 12.50b + 22.50n ≥ 800
Option C is correct.
