Andrew has $40. He wants to buy a $15 CD and as many $6 posters as he can. What is the greatest number of posters Andrew can buy?
write the equation.
(example 3 - 4 > 5)
Answer:
x<5
Step-by-step explanation:
since the CD is a one time purchase, his total amount of money after would be 25.
40-15>6x
25>6x (still have to solve for x)
4.166>x
x<5 (since it has to be a whole number)

Step-by-step explanation:
Which set of numbers can represent the side lengths, in inches, of an acute triangle? 4, 5, 7 5, 7, 8 6, 7, 10 7, 9, 12 Which set of numbers can represent the side lengths, in centimeters, of a right triangle? 8, 12, 15 10, 24, 26 12, 20, 25 15, 18, 20
Answer:
1) 5, 7, 8
2) 10, 24, 26
Step-by-step explanation:
1) For an acute triangle, the square of the longest side is less than the sum of the square of the two smaller sides.
a) 4² + 5² = 16 + 25 = 41
7² = 49 > 4² + 5². Therefore the triangle is not acute
b) 5² + 7² = 25 + 49 = 74
8² = 64 < 5² + 7². Therefore the triangle is acute
c) 6² + 7² = 36 + 49 = 85
10² = 100 > 6² + 7². Therefore the triangle is not acute
d) 7² + 9² = 49 + 81 = 130
12² = 144 > 7² + 9². Therefore the triangle is not acute
2) For a right angled triangle, the square of the longest side is equal to the sum of the square of the two smaller sides.
a) 8² + 12² = 64 + 144 = 208
15² = 225 > 8² + 12². Therefore the triangle is not a right triangle.
b) 10² + 24² = 100 + 576 = 676
26² = 676 = 10² + 24². Therefore the triangle is a right triangle.
c) 20² + 12² = 400 + 144 = 544
25² = 625 > 20² + 12². Therefore the triangle is not a right triangle.
d) 15² + 18² = 225 + 324 = 549
20² = 400 < 15² + 18². Therefore the triangle is not a right triangle.
Clarence earns a 10% commission
on sales plus a $200 weekly salary.
In one week, his sales totaled $2100.
What was his total pay that week?
Answer:
$410
Step-by-step explanation:
Step 1
We calculate the amount of commission of sales
Commission rate = 10%
Total sales = $2100
Hence,
= 10% × $2100
= 10/100 × $2100
= $210
Step 2
The total pay of Clarence for that week
= Commission + Weekly salary
Commission = $210
Weekly salary = $200
Hence,
= $210 + $200
= $410

11x+4y=12
9x-4y=8
Solve it with elimination method
Answer:
x = 1, y = 1/4
Step-by-step explanation:
[tex]11x + 4 y = 12 \ \ \ ---( 1)\\9x -4y = 8 \ \ \ - - - (2)\\\\(1) + ( 2 ) => 20x + 0 = 20\\\\[/tex]
[tex]=> x = 1[/tex]
Substitute x = 1 in ( 1 ) :
[tex]11 + 4y = 12\\4y = 12 - 11\\\\y =\frac{1}{4}[/tex]

[tex]x=2+½*\sqrt{10} [/tex]
or
[tex]x=2-½*\sqrt{10} [/tex]
Answer:
Solution given:
y=2x²-5x+6.....[1]
y=3x+3.........….[2]
solving equation 1&2
2x²-5x+6=3x+3
2x²-5x-3x+6-3=0
2x²-8x+3=0
comparing above equation with ax²+bx+c=0 we get
a=2
b=-8
c=3
by using quadratic equation
[tex]x=\frac{+8±\sqrt{(-8)²-4*2*3}}{2*2}[/tex]
[tex]x=\frac{+8±2\sqrt{10}}{4}[/tex]
taking positive
[tex]x=\frac{+8+2\sqrt{10}}{4}[/tex]
[tex]x=2+½*\sqrt{10} [/tex]
taking negative
[tex]x=2-½*\sqrt{10} [/tex]

Hey can u help me with this question
Answer:
y = 3x - 1
Step-by-step explanation:
→ Substitute x = 1 into all the equations to get y = 2
y = 3x - 1 ⇔ ( 3 × 1 ) - 1 = 2
Answer:
D
Step-by-step explanation:
You can answer this question without even worrying about slope if you know how the y-intercept should be. The y-intercept is where the line crosses the y-axis(the vertical line with the y label in case that needs to be explained.) With that alone, you can determine that the y-intercept is -1 and thus the answer is D. For the slope, try to find a point on the line that is on the grid (A good one is (0,-1) ). Then move from that point to the next point where two of the lines meet like (1,2). Slope is rise/run so you go 3 up and 1 to the right for 3/1 which equals 3.

Complete the Law Of Sines Select the value that belongs to the green box, please somebody!
Answer: [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex]
The sin(A) goes with 'a'
sin(B) goes with b
sin(C) goes with c
Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)}[/tex] and [tex]\frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex] and [tex]\frac{a}{\sin(A)} = \frac{c}{\sin(C)}[/tex]
Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.
