b is the right answer
Step-by-step explanation:
She decides to use the elimination method to find the solution. She multiplies the second equation by 3 and adds it to the first equation to find 14x = 70, showing her that x = 5. Beyonce finds that y = 4.
Step 1: 3(4x + y = 24) → 12x + 3y = 72
Step 2: 2x – 3y = -2
+ 12x + 3y = 72
14x = 70
14x/14= 70/14 → x = 5
Thinking about this process, Beyonce says out loud, “There are lots of ways I could go about solving this problem. I could do the method above or I could multiply the first equation by -2 and add the second.
Step 1: -2(2x – 3y = -2) → -4x + 6y = 4
Step 2: -4x + 6y = 4
+ 4x + y = 24
7y= 28
7y/7= 28/7 → y = 4
“I seem to find that there is only one solution to the two equations, but I wonder if I will get the same solution if I use a different method?”
If Beyonce uses a different method, would she get the same solution? Be sure to show work or explain your reasoning.
Explain how you know that a system of equations has no solution.
Explain how you know that a system of equations has an infinite number of solutions.

What is the common multiple of 2,960 6,400 and 2000 with full process
Answer:
1184000
Step-by-step explanation:
lcm(2960,6400,2000)
prime factor:
[tex]2960=(2^4)(5)(37)\\6400=(2^8)(5^2)\\2000=(2^4)(5^3)[/tex]
Take the largest power of each factor:
[tex](2^8)(5^3)(37^1)\\=1184000[/tex]

312 + 375 = 687
Solve the inequality.
-6n > 54
Answer:
n < 9
Step-by-step explanation:
Solving an inequality is just like solving an equation, one uses inverse operations. The only difference is that when one multiplies or divides by a negative number, one must remember to flip the inequality sign to ensure that the expression remains true.
[tex]-6 n > 54[/tex]
[tex]/ (-6)[/tex]

Whitney has £12 pocket money.
She spends 50% of her pocket money on
magazines.
She spends 33% of her pocket money on apps.
How much pocket money does she have left?
Show the steps in your working.
answer
£2
explanation
12÷50%=6
12÷33%=4
6+4=10
12-10=2
Answer:
2.04 pounds left.
Step-by-step explanation:
Whitney has 12 pounds pocket money
She spends 50% of it on magazines
50% of 12 pounds is 50/100 * 12 = 600/100 = 6 pounds
33% of 12 pounds is 33/100 * 12 = 395/100 3.96 pounds
Total Spent 9.96 pounds
Amount left = 12 - 9.96 = 2.04
She has 2.04 pounds left.

The equation for the circle below is x2 + y2 = 16. What is the length of the
circle's radius?
Answer:
4
Step-by-step explanation:
The general equation circle is
[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]
Where r is the radius
Plug in the equation
[tex] {x}^{2} + {y}^{2} = 16[/tex]
Take the sqr root of 16 tocfind the radius
[tex] \sqrt{16} = 4[/tex]

Answer:
20y - 20
Step-by-step explanation:
We multiply the first term and the second term in the parentheses by the 4. That means we do:
4(5y) + 4(-5)
And we simplify to get:

Answer:
8. 12.8
9. 400
Step-by-step explanation:
8. look at it like a square with a rectangle cut out of it, 4*4 = 16, the rectangle needs a base and to find that base 1.5+0.9 = 2.4, 4-2.4 = 1.6, 1.6*2 = 3.2, 16-3.2 = 12.8
9. look at it like a trapezoid with a triangle cut out of it, add the to bases 14+32 = 46, 46*20 = 920 divided by 2 which is 460, and then area subtract the triangle 12*10 = 120 divided by 2 which is 60, so 460-60 = 400
There are 8 volunteers during the weekday and only 5 volunteers on the
weekend. How many volunteers do you have on Monday and Saturday?
If you have 10 people who need help from the volunteers on Monday,
how many will not get helped if the ratio of volunteers to the person
needing help is 1:1? Show how you got your answer.
Answer:
Monday is a weekday, with which there would be 8 volunteers.
In turn, Saturday is a weekend day, with which there would be 5 volunteers.
2 people will not be helped if the ratio of volunteers to the person needing help is 1:1.
Step-by-step explanation:
Given that there are 8 volunteers during the weekday and only 5 volunteers on the weekend, to determine how many volunteers do you have on Monday and Saturday the following logical reasoning must be carried out:
Monday is a weekday, with which there would be 8 volunteers.
In turn, Saturday is a weekend day, with which there would be 5 volunteers.
In turn, if you have 10 people who need help from the volunteers on Monday, to determine how many will not get helped if the ratio of volunteers to the person needing help is 1: 1 the following logical reasoning must be carried out:
10: 8
1: 1
10 - 8 = 2
Thus, 2 people will not be helped if the ratio of volunteers to the person needing help is 1:1.
