Answer:
Two numbers are 16 and 12
Step-by-step explanation:
Let x and y be the numbers
x + y = 28 (1)
x - y = 4 (2)
y = x - 4 (2')
sub (2') into (1)
x + x - 4 = 28
2x = 32
x = 16
Sub x value into equation (1)
16 + y = 28
y = 28 - 16
y = 12

5. Bobby guessed there were 92 jelly beans in a jar. There were actually 107 2 points
jellybeans. Find the percent of error. Round to the nearest hundredth of a
percent if necessary.
HELP IM IN A QUIZZZ
Answer: 14%
Step-by-step explanation:
From the question, we are informed that Bobby guessed there were 92 jelly beans in a jar when there were actually 107. The percentage error will be:
= Difference in error / Actual value × 100
= (107 - 92) / 107 × 100
= 15/107 × 100
= 0.14 × 100
= 14%

During his first three months with the Houston Astros, Yordan Álvarez's batting average was represented by three hundred seventeen thousandths.
What is the value of the digit in the hundredths place written using numerals and expanded notation?
0.3 and (3 x110)
100 and (1 x 100)
0.01 and (1 x1100)
0.007 and (7 x11000)
Answer:
The correct option is;
0.01 and (1 × 1/100)
Step-by-step explanation:
The given parameters includes;
The batting average of Yordan Alvarez's = 0.317
Therefore, we have;
The digit in the hundredths place = 0.01
The expanded notation for the value of the hundredth place is given by the product of the digit and the place value digit as follows;
The expanded notation = 1 × 1/100.

N=480×10^9
Write N as a product of powers of its prime factors.
Answer:
I got 5^10 x 2^14 x 3
Step-by-step explanation:
1. Do a tree to find 480 as a product of its prime factors
2. You should get 480= 5x2x3x2x2x2x2
3. 10 expressed as a product of its prime factors is 5x2
4. so 10^9 expressed as a product of its prime factors would be
5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
5. You can then write out 480x10^9 as a product of its prime factors
5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
6. change this to use powers
5^10 x 2^14 x 3
N = 5^(10) × 2^(14) × 3
This is about prime factors
By definition, a prime factor is a factor of a number and that factor is also a prime number.
A prime number is one that is divisible by only itself and 1.
The number we have is; 480 × 10^(9)
Now, let's list the prime factors or 480 and they are;
2, 3, 5
Now, using these prime factors alone to get 480, we have;
5 × 3 × 2 × 2 × 2 × 2 × 2 = 480
In powers, gives;
5 × 3 × 2^(5)
Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;
(5 × 2)^(9)
Expanding this gives; 5^(9) × 2^(9) = 10^(9)
Thus;
480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)
This gives;
5^(10) × 2^(14) × 3

You sold a total of 56 student and adult tickets for a total of $328. Student tickets cost $5 and adult tickets cost $8. How many student tickets were sold?
Answer:
The number of student ticket sold is 40
Step-by-step explanation:
Given;
total number of tickets sold,= 56 tickets
total amount the tickets were sold, = $328.
cost of student tickets, = $5
cost of adult ticket, = $8
Let the number of student ticket sold = x
Let the number of adult ticket sold = y
To determine the number of student tickets sold, we will have the following equations;
x + y = 56 ------ equation (1)
5x + 8y = 328 -----equation (2)
from equation (1), y = 56 - x
Substitute the value of y in equation (2);
5x + 8y = 328
5x + 8(56 - x) = 328
5x + 448 - 8x = 328
5x - 8x = 328 - 448
- 3x = - 120
x = 120 / 3
x = 40
Therefore, the number of student ticket sold is 40

Answer:

∠JLK=2x+1=2(27)+1=55
Step-by-step explanation:
∠A+∠K=180
3x+13+∠K=180
∠K=167-3x
∠K+∠L+∠J=180
167-3x+39+2x+1=180
207-x=180
x=27
∠JLK=2x+1=2(27)+1=55
Don't worry, you aren't gonna fail. Take a deep breath and relax. Geometry is tricky but you got this. Have a nice night.
Answer:
x = 27°∠JLK = 55°Step-by-step explanation:
∠AKL is exterior angle and as per property it is equal to sum of two non-adjacent angles:
∠AKL = ∠ KJL + ∠JLK3x + 13° = 39° + 2x + 1°Solving for x
3x - 2x = 39° + 1 - 13x = 27°And finding the value of ∠JLK:
∠JLK = 2x + 1 = 2*27° + 1° = 55°How do you solve -7x – 13 ≥ 8 ?
Answer:
x ≥ - 3
Step-by-step explanation:
Step 1:
- 7x - 13 ≥ 8 Equation
Step 2:
- 7x ≥ 21 Add 13 on both sides
Step 3:
x ≥ 21 ÷ - 7 Divide
Answer:
x ≥ - 3
Hope This Helps :)
Answer: x≤−3
Step-by-step explanation:
So first you -7*x-13-(8)≥0
then you are supposed to pull out like the factors -7x - 21 = -7 • (x + 3)
then you divide both sides by -7 then you flip the inequality sign remember that :). then subtract 3 from both sides. and then you got x ≤ -3 So I really hoped this helped :)
f(x)=6(1-x) what is the value of f(-8)
Answer:
54
Step-by-step explanation:
What the shorthand is telling you is wherever you see an x on the right, you put in -8
f(x) = 6(1- x)
f(-8) = 6(1 - - 8)
f(-8) = 6(1+8)
f(-8) = 6*9
f(-8) = 54
