Answer:
let t= the number of tacos sold
let b= the number of burritos sold
3.25t+7b=552
b=2t
Step-by-step explanation:
Since there were twice as many burrito sold as tacos sold, there were more burritos sold, so if we multiply by 2 the number of tacos sold, we will get the number of burritos sold, meaning b=2t.
The system of equation should be considered as the 3.25t+7b=552 and the value of b should be equivalent to 2t.
Calculation of the equation:here we assume that
t= the number of tacos sold
And, b= the number of burritos sold
As per the situation, the equation be like
3.25t+7b=552
b=2t
So,
put b value in the first equation
3.25t + 14t = 552
t = 3.01
And, b = 1.51

A pile of pebbles has a weight of 95 kg.
Some of the pebbles put into a small bag.
The rest of the pebbles is put into a large bag.
The pebbles in the large bag weighs 45 kg more than the pebbles in the small
What is the weight of the pebbles in the large bag?
Answer:
70kg
Step-by-step explanation:
s = small bag
b = big bag
Equations
s + b = 95
s + 45 = b
plug in
s + s + 45 = 95
2s + 45 = 95
2s = 50
s = 25
plug in to find big bag
25 + 45 = b
70 = b
Answer:
The weight of the pebbles in the large bag is 70kg.
Step-by-step explanation:
This looks like a substitution algebra problem. To do this, I’m going to mark the large bag with (L) and the small bag with the variable, (s). I will make first 2 equations to show the value. The first equation would be L=45+s. The second equation would be 95=L+s. Since L is literally 45+s, add this into the 2nd equation. This would be 95=45+s+s. You should have 95= 45+2s and you would subtract 45 from both sides then. Finally, divide 2s by 2 to get what the small bag weighs, (which is 25kg). To find the large bag’s weight, use the first equation to find the answer. L= 45+s or 25. The answer would bring us to 70 kg.
In how many ways can the numbers 3, 4, 5, 6, 7, 8, 9, and 10 be divided into two sets A and B such that the sum of the numbers in B is three times the sum of the numbers in A?
Answer:
4 ways
Step-by-step explanation:
3+4+5+6+7+8+9+10=52
1/4×52=13
13×3=39
3+10=13
4+9=13

I’m so confused someone please help!
Answer:
Step-by-step explanation:
7x - 42 + 5x = 180 {linear pair}
7x + 5x - 42 = 180 {Combine like terms}
12x - 42 =180
12x = 180 + 42
12x = 222
x = 222/12
x = 18.5
5x = 5*18.5 = 92.5
7x - 42 = 7*18.5 - 42 = 129.5 - 42 = 87.5
Anelle is saving to buy a guitar that costs $350. So far she has saved $105.20. She wants to buy the guitar in 18 weeks. Based on this information, which statement is true?
Answer:
Step-by-step explanation:
350-105.20= 244.80 is still needed
I don't have the statements so...
244.80/18 weeks = 13.60 She'll need to save at least $13.60 a week for 18 weeks to make up the difference.
Answer:
Step-by-step explanation:
18x + 105.2 ≥ 350
18x ≥ 244.8
x ≥ 13.6
She has to save at least $13.6 per week.

In 1980, the population of a town was 2000 people. The exponential function P(t)=2000(1.05)t models the population of the town since 1980. Which statements are true regarding the population of the town? Select THREE that apply.
A.
The population has increased by 5% each year since 1980.
B.
The population has increased by 105% each year since 1980.
C.
The population has increased by 5 people each year since 1980.
D.
Each year since 1980, the population is 105% of the population of the previous year.
E.
Each year since 1980, the population is 1.05 times the population of the previous year.
Answer:
B. The population has increased by 105% each year since 1980.
D. Each year since 1980, the population is 105% of the population of the previous year.
E. Each year since 1980, the population is 1.05 times the population of the previous year.
Step-by-step explanation:
From the question, we are given the exponential function:
The exponential function P(t)=2000(1.05)^t models the population of the town since 1980.
Exponential growth rate =
P(t) = P(1 + r)^t
Where r = growth rate in percentage
P(t) = Size of the population after t years
t = time in years
Hence,
From the formula above, we can say =
1 + r = 1.05
r = 1.05 - 1
r = 0.05
Converting to percentage = 0.05 × 100 = 5%
1.05 can also converted to percentage and this = 1.05 × 100 = 105 %
The population has increased by 105% each year since 1980.
Hence, Options, B, D and E is correct

Use the following table to determine P(X>4).
Answer:
0.11
Step-by-step explanation:
To get the probability above, we simply look for the events greater than 4, then add their probabilities
That is;
P(5) + P(6) + P(7)
So the probability in this case will be;
0.07 + 0.03 + 0.01 = 0.11

Answer:
[tex]x=155[/tex]
Step-by-step explanation:
According to the definition of a linear pair:
[tex](x-25)+(50)=180[/tex]
Solve for [tex]x[/tex].
Combine like terms on the left:
[tex]x+25=180[/tex]
Subtract 25 from both sides:
[tex]x=155[/tex]
Hence, the value of [tex]x[/tex] is 155.
Answer:
x=155, the angle is 130 degrees
Step-by-step explanation:
Assuming you want to find x:
A straight line is 180 degrees so that means
x-25+50=180 add like terms together
x+25=180 subtract 25 from both sides
x=155
If you want to find the degree angle, just replace x with 155
x-25=155+25=130
Also if you want to know, yes I edited my answer as I couldn't tell if that was a + or a - in the picture. Have a nice day and happy thanksgiving!

How do I solve this equation and check the solutions?
Answer: x = -10 or 2
Step-by-step explanation:
Given:
√20 - 8x = x
Step 1: Square √20 - 8x
(√20 - 8x)² = (x)²
20 - 8x = x²
Now we can solve the problem
Step 2: Move 20 - 8x to the other side
20 - 8x = x²
-20 + 8x - 20 + 8x
0 = x² + 8x - 20
This is a quadratic equation
Step 3: Factor the quadratic equation
10(-2) = -20 and 10 - 2 = 8
So our factors are 10 and -2
(x + 10)(x - 2) = 0
Step 4: Create a FOIL equation
For this equation to be true, x would have to make either one of the parenthysis equal to zero
(x + 10)(x - 2)
x = -10 x = 2
10 - 10 equals zero, and -2 + 2 equals zero, so those are your answers.
