Michael spent $18 at a local farmers’ market. The apples he bought cost $2 per pound, and the peppers cost $3 per pound. How many pounds of apples and peppers did he buy?
This equation represents the scenario:
2a + 3p = 18
Choose the equations that are equivalent.
Check all that apply.
p = two-thirds a + 6
p = negative two-thirds a + 6
a = negative 1 and one-half p + 9
a = 1 and one-half p + 9
a = StartFraction negative 3 p + 18 Over 2 EndFraction
Answer:
p = -2/3a +6
a = -3/2 p +9
a = -1 1/2 p +9
a = (-3p+18)/2
Step-by-step explanation:
2a + 3p = 18
Solve for a
2a +3p -3p = 18-3p
2a = 18 -3p
Divide by 2
a = 18/2 - 3p/2
a = 9 - 3/2 p
a = -3/2 p +9
a = -1 1/2 p +9
a = (-3p+18)/2
Solve for p
2a +3p = 18
3p = 18 -2a
Divide by 3
p = 18/3 - 2/3 a
p = 6 -2/3a
p = -2/3a +6
4,000 pounds of sand is used to fill sand boxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes. how much sand can be put in each of the smaller sandboxes?
Answer:
750 pounds each
Step-by-step explanation:
You start with 4000 pounds, and 1000 goes into the big sandbox.
Now you have 3000 pounds left.
These 3000 pounds must be divided into 4 sandboxes, which means
3000/4= Small sandbox capacity=750 pounds

Answer:

Step-by-step explanation:
calm down ...
don't let a strange problem description overwhelm you right away.
always try to work with the things you know first. and only when you run into something you really don't know, start thinking.
so, perimeter.
your know, what a perimeter is ? it is the circumference. all the side lengths added together. the answer to "how much distance would you have to go, to walk all the way around it one time".
so, what is the circumference of the square based on what we know ?
well, it has 4 equal sides, right ? otherwise it would not be a square.
so, the perimeter is 4×(x+2) = 4x + 8
that is perfectly fine.
now to the next part we know.
the perimeter of the triangle is the sum of its 3 sides (otherwise it would not be a triangle).
an isoceles triangle is a special triangle that has 2 equal sides.
so, we actually know all 3 sides (at least relatively) :
x+3
x+5
and ... another
x+3 (because of the isoceles property)
so, the perimeter is
x + 3 + x + 3 + x + 5 = 3x + 11
alright.
and now we also know that both perimeters are of equal length.
what did that mean ?
that both expressions deliver the same result.
therefore,
4x + 8 = 3x + 11
aha !
x = 3
bingo !
therefore, the side lengths of the triangle are
x+3 = 3+3 = 6 (both sides in the top)
x+5 = 3+5 = 8
and that's all there is to it.
it is really not necessary to panic don't you think ?

-28
2. Which integer represents the following: –(–(–65))?
-65
65
Answer:
1. 28
2. -65
Step-by-step explanation:
The rule I learned, was that if there is an even number of negative signs, the outcome is positive. If there is an odd number of negative signs, the outcome is negative.
In the first question, we have 2 negative signs. So the outcome is positive. 28 is positive.
In the second, we have 3 negative signs, so the outcome is negative. -65 is negative.
I hope this helps!

28, -65

What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x – h | + k
The magnitude of the number will always be positive.
For example - The value of time, length, mass, temperature etc will always positive.
The magnitude of the negative 5.8 will be
⇒ |-5.8|
When the value in the mode may be negative or may be positive, but when the mode is removed, then the value becomes positive.
⇒ |-5.8|
⇒ 5.8
The magnitude of the negative 5.8 will be 5.8
Then the correct option is D.

==============================================================
Explanation:
We'll add up the values in the bottom row of the table.
A value like +150 is the same as simply saying 150
The negatives stick around.
Adding up the values in that row gets us
150 + (-50) + 400 + 300 + (-175) + (-250) = 375
This indicates that over the entire 6 month period, the overall change is +375
---------
In other words, the initial investment (call it x) has increased by 375 dollars over the 6 month period.
We can then say:
x + 375 = 1500
x = 1500-375
x = 1125
She initially invested $1125

A square of 81cm² is cut to make two rectangles, A and B
The ratio of area A to are B is 2:3
Work out the dimensions of A and B
Answer:
Length of A: 9
Width of A: 6
Length of B: 9
Width of B: 3
Step-by-step explanation:
If you look at the diagram, you can see that the length of rectangles A and B are the same, and are also the same as they were in the original square. We can find the length of each side by finding the square root of the area of the square to give us the length and width of the square which is 9. Now that we know that the length of both rectangles A and B, we can find the width of both rectangles by taking 9, and splitting it into 3 portions of 3. Since the ratio of area is 2:1, we could also do this with the area, but since we know the lengths are the same, we know the widths are proportional to the area. Using the ratio of 2:1, and the 3 portions of 3, you can combine 2 of these portions to get 6, and since the ratio 6:3 is proportional to 2:1, these measurements can be used as the width of each rectangle. Thus, the answer given above.
Answer:
Length of A: 9
Width of A: 6
Length of B: 9
Width of B: 3

Yes or No
Explain why
Answer:
Question 1. 3.75 x 922
Step-by-step explanation:
for question 1 if u noticed that they both have the same numbers in the same order the only difference is where the decimal point is placed. First u need to anylase both equations to do that u need to look at 922 and 9.22 not the 3.75 and 37.5 because the decimal point doesn't justify anything. So you see 922 is bigger than 9.22. So the answer is 3.75 x 922.

Point P is the intersection of three medians which is called Centroid of triangle.The Centroid divides the line from opposite vertex in the ratio of 2:1.

NEED HELP ASAP NO FALSE ANSWERES. Part B: Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in
cleaning supplies per car wash. Write an equation to represent this situation
Answer:
y = 70x + 35
Step-by-step explanation:
$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)
the +35 is the tips extra/ constant that will be added after the jobs are done.
x is the amount of car washes done
y would be the profit received.
thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)
Answer:
Step-by-step explanation:
Profit = Income less outgo
= (car wash income + tips) - (supplies)
$250 = ($75n + $35) - ($5n), or
$215 = $70n (where n represents the number of cars washed)
This comes out to n = $215/$70, or approximately 3 car washes.

Answer:
Answer: Wheref(the) is the distance in kilometers and the input the is the time in hours
BC f(t) = -5t + 40
CD f(t) = 20. Or f(t)= -20(t/t)+40 OR f(t) = 0t + 20
DE f(t) = -5(t-2) + 40
Step-by-step explanation:
The negative slope means that the distance is decreasing by 5 km/hr when there is movement. Between hours of 4 and 5, the slope is 0, but the distance remains constant at 20. All the options for CD are strange. But they describe the line segment in the graph.
Plug in the values of the hours to check.

Answer:
1. 75 grams of Toasty Oats for 9 grams of protein
2. Toasty Oats
Step-by-step explanation:
By using cross multiplication we can figure out how many grams of Toasty Oats is needed for 9 grams of protein:
[tex]\frac{12}{100}* \frac{9}{x}[/tex] (x) being the grams of toasty oats.
Cross multiply: 12x = 900
solve for x: 900/12 = x
x = 75 grams of toasty oats needed for 9 grams of protein
To find which one has the better ratio of proteins to grams of cereal,
we can multiply the amount of cereal together to get the same denominator
12/100 and 5/45
12/100 * 9
5/45 * 20
to get the same denominator
108/900 and 100/900
we can see the (12/100)*9 has more protein to grams of cereal ratio than (5/45)*20.
Answer:
1. 75 grams of Toasty Oats for 9 grams of protein
2. Toasty Oats
