Step-by-step explanation:
you and a friend go to taco bell for lunch. you order four soft tacos and two burritos and your bill totals $11.50. your friend's bill $12.00 for three soft tacos and three burritos. how much do the tacos and burritos cost?
Answer:
Answer b = $ 2.25 dollars
s = $ 1.75 dollars
Please see how to do, it is good to know the answers but if you know how to solve it thats even better!!
Step-by-step explanation:
Let : s = soft tacos
b = burritos
Step 1: 11.50 = 4s + 2b
12.00 = 3s +3b
Step 2: Solve using subtraction
12 =3s + 3b
-1 (11.50 = 4s + 2b) _ times by -1 so you can subtract
-11.50 = -4s -2b _ once you do this bring the other equation
12.00 = 3s + 3b _ then subtract/ add
_____________+__
0.50 = -s + b _ add s to both sides
s + 0.50 = b _ now you can plug in b into the original equation
12.00 = 3s + 3(s + 0.50) _distribute the 3 to the s and 0.50
12.00 = 3s + 3s + 1.5 _ add like terms
12.00 = 6s + 1.5 _ - 1.5 on both sides
-1.5 -1.5
10.5 = 6s _ divide by 6 to isolate s
1.75 = s _ plug it in to find b
11.5 = 4(1.75) +2b
11.5 = 7 + 2b _ subtract 7 on both sides
4.5 = 2b _ divide by 2 on both sides
2.25 = b
Answer b = $ 2.25 dollars
s = $ 1.75 dollars
X - 11 < 7
Please help✨✨
x menos 11 menor que 7. .............................
Answer:
x < 18
Step-by-step explanation:
We have an inequality and are asked to solve.
To solve, we need to isolate x or by other means get x by itself.
X - 11 < 7
Add 11 to both sides :
x < 18
Now you could ask whether the inequality sign would change, no, this would only happen when you divide by a negative number.

Answer:
the second option, a=3 b=3 c=5
Step-by-step explanation:
first I would change them both into an improper fraction:
9/2 divided by 5/4
dividing is the same thing as mulitiplying by the reciprocal of the second number. so you would mulitply 9/2 x 4/5 = 36/10 and then you simplify back to a mixed number 3 6/10, 6/10 can be reduced so the final answer is 3 3/5.
0.23 or 2.3% which is greater?
Answer:
0.23 is greater

Answer: +52
Step-by-step explanation:
From the question, we are informed that Mary owns 13 shares of a certain stock and that the value of each share went up by 4 dollars.
The total change in value of her shares will be gotten by multiplying the number of shares that Mary has by 4. This will be:
= 13 × 4
= 52

Answer:
b < -7 or b > 7
Step-by-step explanation:
b is surrounded by absolute value bars, which means that whether the value of b is negative or positive, the bars will make it positive. |b| is said to be greater than 7, so the value of b must be:
less than -7 (it can be -8, -9, -10, ...) because the absolute value bars will make it positive.
&
greater than 7 (it can be 8, 9, 10) because it will stay positive anyway.
Therefore, the second answer choice is correct.
I hope this helped! :)

Answer:
-5(x+3) = -5x-15
-5(x+1)+3 = -5x-2
-5(-x-2) = 5x+10
-5x + (x+2) = -4x+2
-5+(x=3) = x-2
Solve for y.
115°
108°
130°
90°
Answer:
115, A
Step-by-step explanation:
The formula to find the total interior angles is ([number of sides] - 2) x 180, so in this case it would be 540, and if you subtract all the other interior angles you wi ll get y! (90,135,112,and 88) (please excuse therandom spaces my spacebar isbroken)
The value of y from the figure is 115 degrees
PolygonsThe given polygon is a pentagon
The sum of an interior angle of the pentagon is 540 degrees
Taking the sum and equating to 540 will give:
90 + 135 + 112 + y + 88 = 540
y + 425 = 540
y = 540 - 425
y = 115 degres
Hence the value of y from the figure is 115 degrees

Solve for b.
3-2(b-2)=2-7b3−2(b−2)=2−7b
Step-by-step explanation:
3 - 2(b - 2) = 2 - 7b
To solve this first distribute -2 to (b - 2)
3 + (-2b + (-2) x -2) = 2 - 7b
when we simplify this it becomes:
3 + (-2b + 4) = 2 - 7b
We take (-2b + 4) out of the parenthesis:
3 - 2b + 4 = 2 - 7b
Now simplify again.
7 - 2b = 2 - 7b
Now send all the b's to one side and constants on the other.
7 - 2 = -7b +2b
5 = 5b
b = 1
25 points. Which problem will graph as shown?
A) 3x - 5 ≥ -14
B) 3x - 5 ≤ -14
C) 3x - 5 > -14
D) 3x - 5 < -14
Answer:
D
Step-by-step explanation:
We can work backwards.
First, notice that we have an open circle. So, we do not have "or equal to." So, we can ignore A and B.
Our final answer is all values less than -3. So:
[tex]x<-3[/tex]
We can multiply both sides by 3:
[tex]3x<-9[/tex]
And then subtract 5 from both sides:
[tex]3x-5<-14[/tex]
So, the answer that matches this will be D.
Instead of working backwards, you can also just solve each inequality. Since we have an open circle, we only need to solve C and D. If we solve C, we get x > -3, and if we solve D, we get x < -3 (as desired). So, D matches the graph shown.
What is the mathematical

How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
The Total number of distinguishable things is m.
Here, Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total of
[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]
If the order matters, then each of those choice of k distinct items would be permuted k! times,
So, total number of choices in that case would be:
[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
We have to find the mathematical representation of 20P4.
[tex]^{20}P_4[/tex]
here, m = 20
k = 4
Now substitute;
[tex]^mP_k = \dfrac{m!}{ (m-k)!}\\\\^{20}P_4 = \dfrac{20!}{ (20-4)!}\\\\^{20}P_4 = \dfrac{20!}{ (16)!}\\\\\\^{20}P_4 = \dfrac{20 \times 19 \times 18 \times 17 \times 16!}{ (16)!}\\\\\\^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]
Hence, the mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.
