David is buying 3 books in a trilogy set for $24.81. He will save $6.69 by buying the trilogy set instead of buying individual books. If each book costs the same amount, how much does each of the 3 books cost when purchased individually?
Answer:
Cost of each individual book = $10.5
Step-by-step explanation:
Given:
Cost of 3 book set = $24.81
Amount save = $6.69
Find:
Cost of each individual book
Computation:
Assume:
Cost of each individual book = a
Total cost = 3a
So,
Total cost = $24.81 + $6.69
Total cost = $31.5
So,
3a = $31.5
a = $10.5
Cost of each individual book = $10.5
Angle J and angle K are complementary angles. The measure of angle J is 18 less than the measure of angle K. Fine the measure of both angles.
Please and thank you.
Answer:
Step-by-step explanation:
If J and K are complementary, then J + K = 90. If J is 18 less than K, then:
J = K - 18. Now we have a system. We'll sub in K - 18 for J to the first equation:
K - 18 + K = 90 and
2K - 18 = 90 and
2K = 108 so
K = 54
Now that we know K, we'll sub in to find J:
J + 54 = 90 so
J = 36

Answer:
1. 5m+4=7m+6
Step 1: Subtract 7m from both sides.
5m+4−7m=7m+6−7m
−2m+4=6
Step 2: Subtract 4 from both sides.
−2m+4−4=6−4
−2m=2
Step 3: Divide both sides by -2.
[tex]\frac{-2m}{-2} = \frac{-2}{2}[/tex]
m=−1
_______________________________
2. −5x+3=2x−1
Subtract 2x from both sides.
−5x+3−2x=−1
Combine −5x and −2x to get −7x.
−7x+3=−1
Subtract 3 from both sides.
−7x=−1−3
Subtract 3 from −1 to get −4.
−7x=−4
Divide both sides by −7.
x= [tex]\frac{-4}{-7}[/tex]
[tex]Faction \frac{-4}{-7}[/tex] can be simplified to [tex]\frac{4}{7}[/tex] by removing the negative sign from both the numerator and the denominator.
x= [tex]\frac{4}{7}[/tex]
_____________________________
3. 5t−3=3t+5
Subtract 3t from both sides.
5t−3−3t=5
Combine 5t and −3t to get 2t.
2t−3=5
Add 3 to both sides.
2t=5+3
Add 5 and 3 to get 8.
2t=8
Divide both sides by 2.
t= [tex]\frac{8}{2}[/tex]
Divide 8 by 2 to get 4.
t= 4
___________________________
4. 3y−55=42y
Subtract 42y from both sides.
53y−55−42y=0
Combine 53y and −42y to get 11y.
11y−55=0
Add 55 to both sides. Anything plus zero gives itself.
11y=55
Divide both sides by 11
y= [tex]\frac{55}{11}[/tex]
Divide 55 by 11 to get 5.
y=5
On a piece of paper, use a protractor and a ruler to construct △ABC with AB=4 in., AC=4 in., and m∠A=60°.
Which statement is true about this triangle?
BC=3 in.
BC=4 in.
BC=5 in.
The length of BC¯¯¯¯¯ cannot be measured.
Answer:
BC 4 in
Step-by-step explanation:
The steps for construction;
Using a ruler draw line AB 4 inches and label the end points A and BAt point A , using a protractor, measure angle 60° and mark with point. Draw a line from A passing through this point extending to a length of 4 inchesMark that point C.Using the ruler, join point C and B and measure BC.From calculation, length BC can be found by the formula;
[tex]BC=\sqrt{a^2+b^2-2*a*b*cosA}[/tex]------where a=b=4 in , cos A = cos 60°
[tex]BC=\sqrt{4^2+4^2-2*4*4*cos60}[/tex]
BC = 4 in
Answer:
bc = 4

Answer #1 and #2 for Brainliest! Plz answer if you know and not just for points
Answer:
#1: A
#2: 2
I apologize if its wrong
Answer: A, 5
Explanation:
Simply create an slope-intercept equation using the given information. The initial fee is $5, which is the y-intercept and $2.75 every stop, which is our slope. The equation is y = 2.75x+5. Since this is an inequality and she's looking for the most amount of stops she can take before maximizing her budget, it needs to be a less than or equal to sign. Change the equation to be 5+2.75S≤21. Subtract 5 from both sides to get 2.75S≤16. Divide 2.75 to both sides to get S≤5.82. This would be estimated to around 5 stops, which would be the largest amount of stops.

A medium pizza at Benny's Pizza costs $13.60 plus $2.50 for each topping. At Ricco's
Pizza, a medium pizza costs $14.60 plus $2 for each topping. For how many toppings
will the pizzas cost the same price?
O 2 toppings
O They will always cost the same.
О 1 topping
O They will never cost the same.
Answer:
They will never cost the same.
Step-by-step explanation:
Answer:
2.5x +13.6 = 2x +14.6 (set them equal to each other and subtract 2x from both sides)
0.5x +13.6 = 14.6 (subtract 13.6 from both sides)
0.5x = 1 (divide both sides by 0.5)
x= 2
at two toppings they will cost the same

1 2 3 4 5 X

1-3

25
Answer:
The slope of a line that is perpendicular to the line
shown in the graph is = 4
Hence, option 'd' is true.
Step-by-step explanation:
From the line equation, let us take two points
(0, 2)(4, 1)Finding the slope between two points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)[/tex]
[tex]m=\frac{1-2}{4-0}[/tex]
[tex]m=-\frac{1}{4}[/tex]
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be:
[tex]-\frac{1}{-\frac{1}{4}}=4[/tex]
Thus, the slope of a line that is perpendicular to the line
shown in the graph is = 4
Hence, option 'd' is true.

If your friend's doctor wants her target heart rate range to be between 143 and 170, and her
average resting heart rate is 62, what is her age?
Answer:
a person can work out 50% of the maximum (50% of 194 is 97) and 85% of the maximum (85% of 194 is 164.9). This means that the target heart rate for a 20-year-old is approximately 97–165 bpm.

Booker and Reginald both collected insects for a science exhibit-collection. The one hundred eighty-seven insects in Reginalds collection are thirty-seven more than twice the number in Bookers collection. How many insects are in Bookers collection!
Answer:
Insects in Bookers collection = 50 insects
Insects in Reginald collection = 137 insects
Step-by-step explanation:
Total insects collected = 187
Reginalds collection are thirty-seven more than twice the number in Bookers collection.
Let
Insects in Bookers collection = x
Insects in Reginald collection = 2x + 37
How many insects are in Bookers collection?
Total insects collected = Bookers collection + Reginald collection
187 = x + (2x + 37)
187 = x + 2x + 37
187 = 3x + 37
187 - 37 = 3x
150 = 3x
Divide both sides by 3
x = 150 / 3
= 50 insects
Insects in Bookers collection = x
= 50 insects
Insects in Reginald collection = 2x + 37
= 2(50) + 37
= 100 + 37
= 137 insects
Total = 50 + 137
= 187 insects

Find the coordinates of point BBB on \overline{AC} AC start overline, A, C, end overline such that the ratio of ABABA, B to BCBCB, C is 2:32:32, colon, 3. B=\large(
Answer:
(0, 2)
Step-by-step explanation:
Given the following
coordinate A (-6, 5)
Coordinate C (4, 0)
Ratio is 2:3
Required
Coordinate of B
Using the midpoint formula expressed as;
M(X,Y) = [(ax1+bx2/a+b), ay1+by2/a+b]
x1 = -6, y1 = 5, x2 = 4 and y2 = 0
a = 2 b = 3
Get X;
X = ax1+bx2/a+b
X = 2(-6)+3(4)/2+3
X = -12+12/5
X = 0/5
X = 0
Get Y;
Y = ay1+by2/a+b
Y= 2(5)+3(0)/2+3
Y = 10/5
Y = 2
Hence the coordinate of B is at (0, 2)
