Answer:
10,11,12
Step-by-step explanation:
X+x+1+x+2
X+2(x+1)=x+2 + 20
X +2x+2 = x+22
3x+2 = x+22
2x +2 = 22
2x = 20
X = 10
Numbers are 10,11,12
Double checking 10+2*11 = 32
12+20 = 32
So it works

PLEASE HELP ME I WILL DO ANYTHING!!!
Answer:
x=11
Step-by-step explanation:
the angles shown are supplementary so they will add up to equal 180 so we write the equation 180=5x+10x+15 and solve for x
step 1 combine like terms
180=15x+15
step 2 subtract each side by 15
165=15x
step 3 divide each side by 15
x=11

What pair of numbers (x, y) will satisfy both equations below?
3x+y=10
−4x+2y=0
A.)x=3 and y = 1y=1 or (3,1)
B.)x=1 and y=2 or (2,1)
C.)x=10 and y=20 or (10,20)
D.)x=2 and y=4 or (2,4)
Answer:
D) x = 2 and y = 4 or (2, 4)
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}3x+y=10\\-4x+2y=0\end{cases}[/tex]
Multiply Equation 1 by -2:
[tex]\implies -6x-2y=-20[/tex]
Add this to Equation 2 and solve for x:
[tex]\implies (-4x+(-6x))+(2y-2y)=(0+(-20))[/tex]
[tex]\implies -10x=-20[/tex]
[tex]\implies x=2[/tex]
Substitute the found value of x into Equation 1 and solve for y:
[tex]\implies 3(2)+y=10[/tex]
[tex]\implies 6+y=10[/tex]
[tex]\implies y=10-6[/tex]
[tex]\implies y=4[/tex]
Therefore, the pair on numbers (x, y) that satisfies both equations is (2, 4)
(2,4)

at the brechin castle sugar factory, the normal working week is 40 hours, during a certain week Mr. Ramnath earned a total of $516.20, but $160.20 was for overtime. calculate how much per hour he is normally paid.
Answer:
$8.90
Step-by-step explanation:
first you have to subtract how much money you get for overtime, 516.20-160.20=356.00 Next you have to divide 356.00 by 40 to find per hour, 356.00/40=8.90.

A box is made of wood with its external dimensions of 154 cm x 100 cm x 84 cm and thickness of 2 cm.
How much wood was used to make it?
Answer:
Step-by-step explanation:
volume of 154×100×84 box = 1,293,600 cm³
dimensions of airspace = (154-4) by (100-4) by (84-4) = 150 by 96 by 80
volume of airspace = 150×96×80 = 1,152,000 cm³
volume of wood used = 1,293,600 - 1,152,000 = 141,600 cm³

step 1 is wrong . The 1st step should be 15² - 9² = c² .
Answer: step A
Step-by-step explanation:
The Pythagorean theorem is a^2+b^2=c^2, where c is always the hypotenuse (the longest side of the triangle). Step A is written as 9^2(thats the a value squared)+15^2(which is the hypotenuse value squared)=c^2. It should be: 9^2+b^2=15^2

One month, Ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 126 hours. Find the number of hours each person worked.
Answer/Step-by-step explanation:
Let x hours be the number of hours Issac worked
x+6 hours be the number of hours Ruby worked
4(x+6) hours be the number of hours Svetlana worked.
x + x + 6 + 4(x+6) = 126
x + x + 6 + 4x +24 = 126
6x +30 = 126
6x = 96
x = 16
Therefore, Issac worked 16 hours.
Ruby worked 16+6 = 22 hours
Svetlana worked 22 × 4 = 88 hours.
If helpful, please mark as brainliest! =)
Answer: Ruby: 22 hours, Isaac: 16 hours & Svetlana: 88 hours.
Step-by-step explanation:
Let's begin by assigning letters to represent our unknowns:
R (hours Ruby worked)
I (hours Isaac worked)
S (hours Svetlana worked)
Now let's see if we can express all three unknowns in terms of one unknown, according to the facts given in the problem:
R = I + 6 (Ruby worked 6 more hours than Isaac)
S = 4R (Svetlana worked 4 times more hours than Ruby)
We can see that we can express the hours Isaac worked in terms of Ruby:
R = I + 6, therefore, I = R - 6
Now we have all three unknowns expressed in terms of one unknown (R). Now we can write an equation to express the given sum of their worked hours (126) in terms of our expressions for one unknown (R):
R + (R - 6) + 4R =126
Now let's solve our equation for the value of R and then use our expressions for R to calculate the values for I and S:
R + R - 6 + 4R = 126
6R - 6 = 126
6R = 126 + 6
6R = 132
R = 132/6
R = 22 (hours Ruby worked)
I = R - 6
I = 22 - 6
I = 16 (hours Isaac worked)
S = 4R
S = 4(22)
S = 88 (hours Svetlana worked)

A plant is 3 inches tall when you purchase it and grows 2 inches per month. Write an equation in slope intercept form that represents the height y(in inches) of the plant after x months.
Answer:
y = 3 + 2x
Step-by-step explanation:
In this scenario, we are given two values which are the initial height of the plant and its growth height. Then we are given a variable which is the number of months (x) that are unknown for us. The growth height needs to be multiplied by the number of months to know how much it has grown in that time period. Then we add this value to the initial height of the plant to calculate the total height (y) of the plant after x number of months. We can apply this information to form the following equation in slope-intercept form.
y = 3 + 2x
Hey eveyone. Im 7th grade 13 years old. Whenever i am at school i always think people think i smell bad. I dont know if its true. I put deoderant on take a shower and EVERYTHING. I dont wanna smell bad. It might just be in my head. Plz respond.
Answer:Researchers say a psychiatric condition characterized by a person's mistaken belief that he or she smells bad is vastly under-recognized. Called olfactory reference syndrome, the condition is "probably very common," says Katharine Phillips, MD, of Rhode Island Hospital in Providence. so you might just be thinking thst in your head man. just shower, brush teeth etc... or this could be a possibility...What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process.

Last year the depth of the river was 4.2 feet deep. This year it dropped 25%. Find the depth of the river this year to cross it.
Answer:
The river is 3.15 feet deep.
Step-by-step explanation:
First let's recognize what we need to find: the depth of the river
We know last year the river was 4.2 feet deep, but it dropped 25%. This means we also need to find how much it dropped. To find this, we need to know what 25% of 4.2 is. Write an equation for this.
y = 25% of 4.2
y = 0.25 • 4.2
y = 1.05
This means that the river dropped 1.05 feet. To know its depth now, we need to subtract 1.05 from 4.2. Write an equation for this.
d = 4.2 - 1.05
d = 3.15
The river is 3.15 feet deep.
Hope this helps!

What is the solution to the system of equations
Answer:
(2, - 5 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 1 → (1)
4x + y = 3 → (2)
Substitute y = - 3x + 1 into (2)
4x - 3x + 1 = 3
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = - 3(2) + 1 = - 6 + 1 = - 5
solution is (2, - 5 )
What is the solution of the following system? Use the substitution method.
y – 2x = 8
16 + 4x = 2y
O The only solution is (24, 0).
O The only solution is (1, 10).
○There is no solution.
O There are an infinite number of solutions.
Answer:
y-2x=8 (label equation 1)
16+4x=2y (label equation 2)
divide equation 2 by 2 to find y
y=2x+8
sub this in equation 1
(2x+8)-2x=8
2x+8-2x=8
8=8
once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B
arrange the variables so that they are on the same sides: -5w - 9 = 3w + 7
Answer:
-8w=16
Step-by-step explanation:
-5w-9+9 = 3w+7+9
-5w=3w+16
-5w-3w=3w-3w+16
-8w=16
To solve:
-8w/-8=16/-8
w = -2
