Answer:
-19x
Step-by-step explanation:
so you start with -8 and when you subtract 11 from -8 its the same as adding them but because your subtracting you'll decrease which make the answer -19x. (hopefully this made sense)
let f(X)=x^2+2 and g(X)=1-3x
Answer:
1. y = x2+2
2. g = (-3x+1)/x
Step-by-step explanation:
1. No explanation
2.
Let's solve for g.
gx=1−3x
Step 1: Divide both sides by x
gx /x = −(3x+1 )/x
g = (-3x+1)/x

-2(x+5)=20 what is x
Answer:
x = -15
Step-by-step explanation:
Divide both sides by -2
x + 5 = -10
x = -15
Answer: x = -15
Step-by-step explanation:
-2(x + 5) = 20
-2x - 10 = 20
Add 10 to both sides
-2x = 30
Divide both sides by -2
x = -15
The system x-6y=4, 3x-18y=4 has no solution.
Change one constant or coefficient to make a new system with an infinite number of solutions.
Answer:
x - 6y = 4, 3x - 18y = 12Step-by-step explanation:
If we multiply the first equation by 3 we get the same left sides in both equations:
3x - 18y = 12
3x - 18y = 4
To make system with an infinite number of solutions we need to make the left sides the same as well.
The required resulting equation that gives infinite solution will be x-6y= 3 and 3x-18y= 12
System of equationsSystem of equations can have difference kinds of solutions ranging from no solution, infinite number of solutions and real solutions.
For the system of equation that has infinite number of solutions, the two equations must be equal.
Given the system of equations
x-6y=4,
3x-18y=4
For the equation to have infinite number of solutions, we need to multiply the constant in equation 2 by 3 to have 4(3) = 12
Hence the required resulting equation that gives infinite solution will be x-6y= 3 and 3x-18y= 12

Jocelyn estimates that a piece of wood measures 5.5cm. If it actually measures 5.62 cm, what is the percent error of Jocelyn’s estimate?
Answer:
2.14% error
Step-by-step explanation:
Use the percent error formula:
| (observed - expected) / expected | x 100
Plug in the observed and expected values:
| (observed - expected) / expected | x 100
| (5.5 - 5.62) / 5.62 | x 100
Calculate:
= 2.14% error
So, the percent error of Jocelyn's estimate is 2.14%
Aubrey finished 2/9 of a project on Monday and 1/4 of the project of Tuesday. How much of the project has Aubrey completed?
Answer:
17/36
Step-by-step explanation:
We have to find a common denominator, so the first common denominator for 4 and 9 is 36. 9x4=36, so we multiply 2 by 4, which equals 8. 4x9-36, so we multiply the 1 by 9, and get 9. Then we add the numerators, 8 and 9, and get 17. So it's 17/36

During the fall, you charge $10 to go to a house
and rake the leaves and an additional $8 for
every hour that you rake the yard. If you earned
$42, how many hours did you spend raking the
leaves?
Answer:
4 hours
Step-by-step explanation:
you take 42-10 because you take the total you made minus the $10 you chare to go to the house
then you take 32 divided by 8 for each hour spent
= 4 hours spent raking
If he earned $42 he spent 4 hours raking the leaves
During a fall he charges $10 to go to a house and rake the leaves and an additional $8 for every hour that he rakes the yard.
Therefore, the equation can be represented as follows;
Linear equationy = 8x + 10where
x = number of hours
y = total charges
Therefore, If he earn $42 the number of hours worked can be calculated as follows:
42 = 8x + 108x = 42 - 10
8x = 32
x = 32 / 8
x = 4
Therefore, he works 4 hours to earn a total of $42

Sasha uses 6.1 pints of white paint and blue paint to paint her bedroom walls. 2/5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer: 3.66 pints of blue paint.
Step-by-step explanation:
She used 2/5 of the total number of pints to paint white.
That number in pints is:
= 2/5 * 6.1
= 2.44 pints of white
The number of pints used to paint blue is therefore:
= 6.1 - 2.44
= 3.66 pints of blue paint.

In one day, Ricardo hiked 2_ 2 3 times as far as Bernie and Chloe hiked before they ate lunch. How far did he hike?
Complete question :
Bernie and Chloe hiked the Tremont Trail to the end and back. Then they hiked the Wildflower trail to the end before stopping to eat lunch. Before Ricardo ate his lunch, he hiked 2 2/3 times as far as Bernie and Chloe. How far did he hike?
Required diagram is attached below
Answer:
25 miles
Step-by-step explanation:
Tremont Trail = 3 1/2 miles
Wildflower trail = 2 3/8 miles
Distance covered ; Tremont Trail and back : (3 1/2 * 2). = 7/2 * 2 = 14 /2 = 7 miles
Total distance covered by Bernie and Chloe before stopping for lunch /
(7 miles + 2 3/8 Miles) = 9 3/8 miles = 75/8 miles
Ricardo's distance = 2 2/3 * Bernie and Chloe's total distance
Ricardo's distance = 8/3 * 75/8 = 600 /24 = 25 miles

The sum of three consecutive odd integers is fifty-one. Find the integers. (Enter your answers as a comma-separated list.)
Answer:
15, 17, 19
Step-by-step explanation:
let the first odd number be n then the next 2 are n + 2 and n + 4 , then
n + n + 2 + n + 4 = 51
3n + 6 = 51 ( subtract 6 from both sides )
3n = 45 ( divide both sides by 3 )
n = 15
Then
n + 2 = 17 and n + 4 = 19
The 3 consecutive odd numbers are 15, 17, 19
