The sum of two numbers is 179.
Their difference is 133. Find both numbers.
Answer:
156,23
Step-by-step explanation:
let the numbers be x and y and x>y
x+y=179
x-y=133
add
2x=312
x=156
156+y=179
y=179-156=23
Answer:
156 and 23
Step-by-step explanation:
We can use system of equations to solve this problem.Step 1: Set up the system of equations.
[tex]\left \{ {{x+y=179} \atop {x-y=133}} \right.[/tex]Step 2: Solve x + y = 179 for x.
[tex]x + y = 179[/tex] [tex]x + y - y = 179 - y[/tex] (Subtract y from both sides)[tex]x = -y + 179[/tex]Step 3: Substitute -y + 179 for x in x - y = 133.
[tex]x-y=133[/tex] [tex]-y+179-y=133[/tex] [tex](-y-y)+(179)=133[/tex] (Combine like terms)[tex]-2y + 179 = 133[/tex] [tex]-2y + 179 - 179 = 133 - 179[/tex] (Subtract 179 from both sides)[tex]-2y = -46[/tex] [tex]\frac{-2y}{-2} = \frac{-46}{-2}[/tex] (Divide both sides by -2)[tex]y = 23[/tex]Step 4: Substitute 23 for y in x = -y + 179
[tex]x = -23 + 179[/tex] [tex]x = 156[/tex]Therefore, the numbers are 156 and 23.

How do I rewrite the quadratic function in standard form
Answer:
6x^2 -36x + 58
Step-by-step explanation:
expand (x-3)^2 = x^2 -6x +9
6(x-3)^2 +4=6(x^2 -6x +9) +4 =6x^2 -36x + 54 +4 = 6x^2 -36x + 58

Answer:
Removing the cat's eye is the beginning of the end, so to speak, for the narrator. Until that moment, the cat had thus far escaped his drunken cruelty, so this act signifies that the narrator had reached a certain mental point: there were no longer any limits to his violent behavior.

Can u help me with this please it’s due in 5 mins. Find value of x.
Answer:
x = 35°
Step-by-step explanation:
Co-interior angles add up to 180°, so:
2x + 43 + 2x - 3 = 180° (now, simplify)
4x + 40 = 180° (subtract 40 from both sides)
4x = 140° (divide both sides by 4)
x = 35°
Hope this helps!
Answer:
x=35
Step-by-step explanation:
given: two lines cut by a transversal to find x
solution: the given two angles are supplementary since they are consecutive interior angles.
(2x+43)+(2x-3)=180°
⇒ 4x+40=180°⇒4x=140°
⇒x=[tex]\frac{140}{4}[/tex]=35
hope this helps :)
8 to the second power.(2+6) divided by 4=
The value of given numerical expression is 128.
The given numerical expression is [8²×(2+6)]/4.
What is the exponent?Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.
Now, the given expression can be solved as follows:
[8²×(2+6)]/4
= (64×8)/4
= 64×2
= 128
