1. x + 2x - 1 = 38
Inverse operation
Answer:
x=13
Step-by-step explanation:
First, you add the x's together: 2x+x=3x
Now you have:3x-1=38
Add 1 to both sides: 3x=39
1 cancel on the left side of the equation
Divide 3 on both sides: x=39/3
3 cancels on the left side and 39 divided by 3 is 13:
x=13

Find the 82nd term of the arithmetic sequence -8,9,26...

Step-by-step explanation:
Answer:
1369
Step-by-step explanation:
Calculate the measure of ∠ PMU and ∠ UPM.
m∠ PMU =
m∠ UPM =
Answer:
you want to find angle PMB to find PMU
180-21-35= 124
so now, you subtract 180-124 to find PMU
180-124= 56
Now, subtract 56 and 62 from 180 to find angle UPM
180-56-62= 62
m< PMU = 56
m<UPM = 62
Step-by-step explanation:
So we know that a triangle adds up to 180 degrees. Take 62+35 and subtract it from 180 to find angle P.
62+35=97
180-97=83
Knowing this you can find the two angles of P. You can subtract this number from 21 to find the unknown angle of P.
83-21=62(angle UPM)
Then do the same steps for finding the M angles
(Left Triangle)
62+62=124
180-124=56
(Right Triangle)
21+35=56
180-56=124
And because M intersects a straight line, the M angles should add up to 180.
56+124=180

--> The managers want to know how many boxes of 12 cookies can
be filled with the 3,258 cookies that have been baked. Fatima
starts by subtracting the largest number of boxes she can easily
calculate. She knows that 100 boxes of 12 cookies can be put into
one crate. How many crates can be filled from the total of 3,258
cookies?
Answer:
271 boxes
Step-by-step explanation:
Answer:
3 crates are required for 3258 cookies
Step-by-step explanation:
since the boxes can have 12 cookies each
number of boxes = number of cookies / number of cookies per box
number of boxes = 3,258 cookies / 12 cookies/box = 271.5 boxes = 272 boxes (271 completely filled and one halfway filled)
since each crate can hold 100 boxes
number of crates = number of boxes / number of boxes per crate
number of crates = 272 boxes/ 100 boxes/crate = 2,72 crates = 3 crates (2 completely filled and one 72% filled)
therefore the number of required crates for 3258 cookies is 3

drag components to describe a sequence of transformations that will show triangle abc is equal to triangle def
Answer:
Step-by-step explanation:
From the figure attached,
ΔDEF is the image triangle formed by the sequence of transformations of ΔABC.
Step -1
ΔABC is reflected across line BC to get the inverted form of ΔA'B'C' (As shown in the image attached)
Step -2
Further ΔA'B'C' is translated by 4 units to the right to get the image ΔA"B"C".
Step - 3
Further ΔA"B"C" is translated 1 unit down to get the image ΔDEF.

Find the equation of the line parallel to -2x +y = 3, that passes through the point
(-3,-1). Write your answer in slope-intercept form. Do not use spaces in your
answer. Enter any fractions like a/b or -a/b.
Answer:
y=-2x-9
Step-by-step explanation:
First, convert -2x+y=3 to an expression in slope-intercept form. This will be written as y=-2x+3.
Parallel lines have the same slope.
So, the slope of the new line will also be -2x.
Now, use the given coordinates and put them and the slope into point-slope form.
Point slope: y-y1=m(x-x1)
y+3=-2(x+3)
Finally, distribute -2 to (x+3) and simplify the equation.
y+3=-2x-6
y=-2x-9

Olivia filled 4 baskets of apples. Her friend filled up one additional basket of apples. if all of the baskets sold for a total of $160, how much money did each basket of apples cost?
Answer:
$32
Step-by-step explanation:
Since the question says that all the apples were sold for a total of $160, this means that you have to add the additional basket of the friend's to Olivia's. Since Olivia has 4 baskets of apples and her friend has 1, 4+1=5. Since you're trying to find the unit price for 1 basket, you take the total of $160 and divide it by 5 to find how much each basket of apples costed. Since 160/5 is 32, $32 is your answer.

In your own words, what do the terms sales tax and discount mean? Is a 5 percent sales tax a percent of increase or decrease? What about a 15 percent discount?
lol help-
Answer:
Sales tax is an increase in the price of the item while a discount is the decrease of the price. A 5% sales tax is an increase since your paying an extra 5% of the item price. 15% discount is a decrease since your now only paying 85% of the original price. Hope that helps
Answer: In layman's terms, that means if the original price of something you sell was $100, but you offer a 50% discount, then the taxable price is $50. Sale Price = original price – (% of discount * original price)
Sales Tax = Sales Tax rate * Sale Price.
Sales Tax = 0.05 * $17.21 = $0.8605 = $0.86. How do I add 5% to a number?
Divide the number you wish to add 5% to by 100.
Multiply this new number by 5.
Add the product of the multiplication to your original number.
