Answer:
52
Step-by-step explanation:
I think it would probably just be 52 because if you replace (x) with (2) and simplify the equation, you get 52.
32x-12
*replace x with 2*
32(2)-12
*multiply 32 by 2*
64-12
*solve 64-12*
52

A pair of shoes is on sale for 15% off. With this discount, customers will save $9 if they buy the shoes. 15% is the whole, part or percent. $9 is the (blank) and the original price is (blank).
Answer:
$9 is the part, 15% is the percent, and $60 is the whole.
Step-by-step explanation:
$9 is %15 of the whole. This means $9 is the part, 15% is the percent, and the whole is the total cost of the shoes after the discount. The total cost of the shoes after the discount is 60.
what is the area of the figure
CORRECT THE ERROR 1) 4a^(2)*3a^(5)=(4+ 3)a^(2+5)=7a^(7) // 2) x^(6)x*x^(3)=6^(4+3) //
3) 3^(4)*2^(3)=6^(4+3)

Helen received a 40% discount on older model apple watch and saved two hundred and thirty dollars. What was the final selling price of the watch?
Answer:
Final selling price: 575 dollars.
Step-by-step explanation:
Since we know that 40%=230 that means 20%=115.
With this information, I can multiply 115 by 5 to get the answer which is 575.

Ihmani is going to the state fair. Each ticket for carnival games is $0.50, but she has to pay a $10 admission fee. Plot this scenario on the graph below. Does it show a proportional relationship? Why or why not?
Answer:
the answer is yes it does show a proportional relationship.
Step-by-step explanation:
Lets put it in a table:
T C
1 .5
2 1
3 1.5
4 2

Answer:
27 cm²
Step-by-step explanation:
There are many ways the figure can be decomposed into parts for which you know the area formula. The total area is the sum of the parts.
__
decompositionWe recognize that each of the tabs is twice as long as wide, so is half a square. The 4 tabs together make 2 squares that are 3×3 cm. Of course, what remains after removing the tabs is a 3×3 cm square in the middle of the figure.
sum of partsThen the total area is that of 3 squares measuring 3 cm × 3 cm:
A = s² = (3 cm)² = 9 cm² . . . . . area of one square
total area = 3A = 3(9 cm²) = 27 cm²
The area of the figure is 27 cm².
_____
Alternate solution
The figure can also be considered to be a 6 cm × 6 cm square with four 1.5 cm × 1.5 cm squares removed from its corners. Then the area is ...
(6 cm)² -4(1.5 cm)² = (36 -4(2.25)) cm² = 27 cm²

A water well drilling rig has dug to a height of -60 feet after one full day of continuous use.
Assuming the rig drilled at a constant rate, what was the height of the drill after 15 hours?
Answer:
-3.75 feetStep-by-step explanation:
If the water well drilling rig dug to a depth of -60 feet after one full day of continuous use, we can assume that the rig drilled at a constant rate throughout the day.
To determine the height of the drill after 15 hours, we need to calculate the average rate of drilling per hour.
PLEASE MARK AS BRAINLIEST
The rate of drilling can be calculated by dividing the total depth (-60 feet) by the total time (24 hours):
Rate of drilling = Total depth / Total time
= -60 feet / 24 hours
= -2.5 feet per hour
Now we can calculate the height of the drill after 15 hours using the rate of drilling:
Height of the drill after 15 hours = Rate of drilling × Time
= -2.5 feet per hour × 15 hours
= -37.5 feet
Therefore, the height of the drill after 15 hours is -37.5 feet.
Beth is solving this equation: 1/x + 3= 3/x
she says i can multiply both sides by x and get the linear equation 1 + 3x = 3, whose solution is x= 2/3
which of the following statement makes a correct argument, or shows that it is incorrect? select all that apply
A. you can assume x ≠ 0 because both sides are undefined if x = 0
B. after multiplying both sides by x you need to subtract 1 from both sides
C. you cannot multiply both sides by x because you do not know what x is.
D. the equation is not linear, so you cannot use the methods normally used for solving linear equations.

Abbigail brought 47 bags of candy for the party. Each bag contained 21 pieces of candy. If there are 500 people at the party, does she have enough to give everybody 2 pieces of candy?
Answer:
No
Step-by-step explanation:
because you multiply 21 times 47 =987 and there is 500 people if Abbigali wants to give ereyone 2 he has to have 1,000
Answer: no
Step-by-step explanation:
47 bgs tims 21 in each bag gives
47 x 21 = 987 candies in all
if there are 500 people then lets divide the number of candies by the number of people to see how much each person gets
so 987/500 = 1.97
so NO there would not be enough candies for each person to get 2
as you see each person will get 1.97

For problem 3, the solution is x = 105For problem 4, the solution is x = 75==========================================================
Explanation for problem 3
For any convex polygon, the sum of the interior angles is equal to 180(n-2), where n is the number of sides.
In this case, we have a hexagon with 6 sides, so n = 6
The interior angles for the hexagon add to 180(n-2) = 180(6-2) = 720
We'll add the given angles and set that sum equal to 720, then solve for x.
135+110+125+120+125+x = 720
615+x = 720
x = 720-615
x = 105
-------------------------------------
Explanation for problem 4
We'll use the same formula and idea as the previous problem.
This time we have n = 4 sides. This is a quadrilateral.
The interior angles add to 180(n-2) = 180*(4-2) = 360 degrees
So,
x+90+80+115 = 360
x+285 = 360
x = 360-285
x = 75
Note: the square angle marker represents 90 degrees

Answer:
m=0.5 b=1
Step-by-step explanation:
M is the increase in value by one square point via b.
B is the y axis beginning position.
I could be wrong, though.
Answer:
m=1/2 b=1
Step-by-step explanation:
y=mx+b
The y-intercept is b, and the slope is m.
Let's see, the slope is rise/run. the first coordinate is (0,1) and the second is (4,3). 2/4 would be 1/2, so the slope would be 1/2. S0, m is 1/2.
y-intercept is the starting point. We can easily see that the y-intercept is 1, because the first point was (0,1).
so the final equation: y=1/2x+1
