y=32/3
Answer:
y=32/3
Step-by-step explanation:
let the number be y, then
24+3y=56 solve for y, subtract 24 from each side
3y=32 divide each side by 3
y=32/3

HELP ME PLEASE!!! 12 points!
Answer:
-18
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Parentheses first so
7-10=-3
then the brackets
-2-3-15=-20
-4-20=-24
so thats the numerator
the denominator is
2(-1)=-2
-20/-2= ?
We can remove the negative because two negatives make a positive then we would divide by 2
20/2=10
and that's our answer! :)

Use the Completing the Square method to solve for x.
y= (x + 3)2 – 4.
OX= 1 & 5
Ox= -1 & 5
O x = 1 & -5
OX= -1 & -5
Answer:
x = -1
x = -5
Step-by-step explanation:
y= (x+3)^2 - 4
(x + 3)^2 = x^2+6x+9
y = x^2 + 6x + 9 - 4
y = x^2 + 6x + 5
x^2 + 6x = -5
x^2 + 6x + 9 = -5+9 (6/2=3, 3^2 = 9) (add 9 to both sides)
(x + 3)^2 = 4
x + 3 = sqrt 4
x + 3 = +- 2
x + 3= 2. x = 2-3. x = -1
x + 3 = -2. x = -3-2. x = -5
Solve the math problem
x+50+70+4x=180
combine like terms
50+70=120
subtract 120 by both sides
x+4x=60
combine like terms
5x=60
divide by 5
x=12
4x12=48
B=48
12+50=62
48+62=110
110+70=180
x=12
A=62
B=48
lols ppz help1/2 (2 1/2×4 4/5-7 1/2)????,,,,,
Answer:
If you've written it correctly, the answer is 2.25.
Step-by-step explanation:
Can be written as:
0.5 * (2.5 * 4.8 - 7.5).
Perform the multiplications inside the brackets, first:
0.5 * ( 12 - 7.5)
Then perform the remaining arithmetic inside the brackets:
0.5 * ( 4.5)
Perform the last arithmetic:
2.25.
Again, that's if you've written it correctly, and when you say 4 4/5-7 1/2 this actually means four and four fifths (4.8) minus seven and a half (7.5).

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
If the decimal is moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

A=2π(3)(15)+2π(3)^2
A=339.29in^2
Hope that helps
Answer:
Step-by-step explanation:
Hi there!
From the given figure;
Radius(r) = 3 inch
Height (h) = 15 inch
Now;
Total surface area (TSA) = 2πr(r+h)
TSA = 2*([tex]\frac{22}{7}[/tex])*3(3+15)
TSA = [tex]\frac{132}{7}[/tex]*18
TSA = 339.42in².
Therefore, the answer is option c (339.29in²).
Hope it helps!

Answer:
x = 131
Step-by-step explanation:
the angle adjacent to x on line l corresponds to 49° and are congruent, then
49 and x are adjacent and sum to 180° , that is
x + 49 = 180 ( subtract 49 from both sides )
x = 131

A regular pentagon, a regular octagon, and∠ meet at a point. What is m< SBY?
Answer:
117
Step-by-step explanation:
Each angle of a regular pentagon = 108
Each angle of regular octagon = 135
135+ 108 + ∠SBY = 360
243 + ∠SBY = 360
∠SBY = 360 - 243
∠SBY = 117°

Answer:
The equation is 39=3r-6
Step-by-step explanation:
Let x = # of years from the start of the Great Depression to the first Presidential election of Nixon
Let r = Raul's age
The question gives us what x equals so...
x=39
Now we just turn the sentence into an equation.
"The number of years from the start of the Great Depression to the first Presidential election of Nixon [(x)] is six years less than three times Raul's age [(3r-6)]"
Remove the icky words...
x=3r-6
replace x with what it equals (39)
39=3r-6
Now you can go on to olve it
Overal Raul is only 15 :)

Answer:
substitute the values given,
= (2a + b) - (a - 2b)
= (2(x + 2y) + x - 2y) - (x + 2y - 2(x - 2y))
= (2x+4y+x-2y) - (x+2y-2x+4y)
= (3x+2y) - (-x+6y)
= 3x + 2y + x - 6y
= 4x - 4y
then,
(2a+b) - (a-2b) = 4x - 4y
4x+3y=16 x= -3 and y= -2 Solve the equation
Answer:
Is this question wrong?
Step-by-step explanation:
4x+3y=16
4(-3)+3(-2)=16
-12-6=16
-18=16
