Answer:
(168,12)
Step-by-step explanation:
Substitute x = 10y+48 in the first equation.
[tex]10y + 48 + y = 180 \\ 11y = 180 - 48 \\ 11y = 132 \\ y = \frac{132}{11} \\ y = 12[/tex]
We have got the y-value. Our next goal is to find the x-value by substituting y-value in any given equations.
For me, I will be substituting y = 12 in the first equation.
[tex]x + 12 = 180 \\ x = 180 - 12 \\ x = 168[/tex]
Answer Check
Substitute both x-value and y-value in both equations.
[tex]168 + 12 = 180 \\ 180 = 180[/tex]
Our first equation is true for both values.
[tex]168 = 10(12) + 48 \\ 168 = 120 + 48 \\ 168 = 168[/tex]
Our second equation is true for both values.
Thus, the answer is (168, 12)

Question was not formatted properly and in the proper format, the above is the answer.
1²/₅ - ²/₅ = 1
Any number therefore that is lower than ²/₅ will when subtracted from 1²/₅ give an answer greater than 1 because when ²/₅ was subtracted from 1²/₅, it gave 1 as an answer.

Which system of equations has infinitely many solutions? On a coordinate plane, 2 lines are parallel to each other. On a coordinate plane, 2 lines intersect at (negative 1, 0). On a coordinate plane, a line has a negative slope.
Answer:
On a coordinate plane, a line has a negative slope
Step-by-step explanation:
If a graph only shows one line, there is an infinite amount of solutions. We need two separate line equations to cross at a point in order to find the solution to the system. However, if a graph shows two parallel lines that never cross, there are no solutions to that systems of equations.

Is y=-3.5x-10 proportional
Answer: =3.5x Slope:
3.5
y-intercept:
0
Step-by-step explanation:
y=-3.5x-10 is an inverse proportional.
Given that, the given equation is y= -3.5x-10.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
Put x=0, 1, 2, 3, and 4 in the given equation.
When x=0
y=-10
When x=1
y=-3.5(1)-10
=-3.5-10
=-13.5
When x=2
y=-3.5(2)-10
=-7-10
=-17
When x=3
y=-3.5(3)-10
=-10.5-10
=-20.5
Here, x increases and y decreases, it is inverse proportionality
Therefore, y=-3.5x-10 is an inverse proportional.

Find the value of a.
Answer: 14
Step-by-step explanation: The perimeter is all of the side added together. When finding the perimeter of a rectangle the opposing sides have the same value. So the equation would be 2(12) + 2(a) = 52. 12 x 2 is 24. 52- 24 is 28 and youre left with 28 = 2(a). You divide each side by 2 and get 14 = a

The red sox play 118 games in 110 days what is their rate for games played to days?
Answer:
= 1.072727 games per day
Step-by-step explanation:
This is a fraction equal to
118 games ÷ 110 days
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 110
118 games ÷ 110
110 days ÷ 110
=
1.072727 games
1 day
=
1.072727 games
day
= 1.072727 games per day

• 20 hydrogen
Answer:
Simple Answer... Yes it is balanced.
CAN SOMEONE FIND "x" FOR ME PLZ :/
Answer:
9°
Explanation:
So, since the arrow is pointing to a RIGHT angle, you have to know the right angle's degree is 90° so set up an equation.
11x - 9 = 90
Now you solve it. Here's a step by step:
11x - 9 = 90
Add nine to nine and ninety. Since the nine in this equation is negative, it'll cancel it out. Now here's what you have left to solve:
11x = 99
Divide -11 from 11 and 99.
x = 9
If you feel like you're wrong, fill it in!
11(9) - 9 = 90
11 x 9 = 99
99 - 9 = 90
There you go!

What is a simpler form of the following expressions?
(7m2 - 5)(7m2 + 5)
(This is a rushed one so pls help?)
Answer:
49m^4 - 25
Step-by-step explanation:
The simpler expression can simply be found by expanding
The kind of expansion we have here is the difference of two squares
(a + b)(a-b) = a^2 - b^2
Thus, we have it that;
(7m^2-5)(7m^2 + 5)
=
49m^4 - 25
Determine the intercepts of the line.

whats 41.803 rounded to the nearest whole number
41.803 is 42 rounded to the nearest whole number because when you go past .5 you round to the nearest highest number, but when your below .5 then you round to the nearest lowest number.
Answer: 41.803 rounded to the nearest whole number would be 42. Whenever you go over .5 you round to the nearest highest number. For example, 41.6 would also be rounded to 42.
