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

Write in Slope Intercept form
Answer:
y=5/2x
Step-by-step explanation:
the y intercept is (0,0) so it isn't included in the equation. now we know the middle solution isn't correct. the points we use to find slope are (-2,-5) and (2,5) which ends up being 5/2.

y= -2x+6 and y=3x-4
check:
Answer:
X= 2
y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6
y=-4+6
y=2

Solve for n
Please show steps thanks so much
Answer:
n = 7.2
Step-by-step explanation:
I just divided both sides by 5.
5n (÷ 5) = 36 (÷ 5)
n = 7.2 or 7 [tex]\frac{1}{5}[/tex]
You can choose between using the decimal or the fraction.
Answer:
n=7.2
Step-by-step explanation:
=> 5n=36
=> 5n/5 =36/5 [Divide by 5 on both the sides]
=> n=7.2

Use quadrilateral ABCD. What value for m DAB would show ABCD is a parallelogram?
Answer:
m∠DAB = 101°
x = 7
y = 12
Step-by-step explanation:
Properties of a parallelogram,
1). Opposite sides of a parallelogram are equal and parallel.
2). Opposite interior angles are equal in measure.
3). Consecutive interior angles are supplementary.
By the first property,
BC ≅ AD
2x + 4 = 3x - 3
3x - 2x = 4 + 3
x = 7
AB ≅ CD
2y + 10 = 3y - 2
3y - 2y = 10 + 2
y = 12
By second property,
m∠ABC = m∠ADC
2z + 15 = 3z - 17
3z - 2z = 15 + 17
z = 32
Therefore, m∠ADC = (3z - 17)°
= 3(32) - 17
= 96 - 17
= 79°
By third property,
m∠ADC + m∠DAB = 180°
79° + m∠DAB = 180°
m∠DAB = 180° - 79°
m∠DAB = 101°
A library has 2000 books. There are 3 times as many non fiction books as fiction books. Write and solve an equation. PLEASE HELP ASAP!!!???
Answer:
x = fiction books
3x = nonfiction books
x + 3x = 2000
After you solve for x, (which is the number of fiction books), you can plug its value into the equation for nonfiction books (3x) and that will give you the number of non fiction books.

Which angles are corresponding angles?
Check all that apply.
The corresponding angles are
2 and 6
3 and 7
5 and 3
and, 4 and 8
What are corresponding angles?
Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal are called corresponding angles.
Or, when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.
According to the given question.
We have a diagram, in which there are two parallel lines and one another line which is intersecting these two lines.
From the given diagram,
The pairs of angles 2 and 6, 1 and 5, 3 and 7, and 4 and 8 are occupying the same relative positions, upper right side, upper left side, lower left side, and lower right side respectively.
Therefore, we can say that angles
2 and 6
3 and 7
5 and 3
and, 4 and 8
are corresponding angles.

Classify the following triangle. Check all that apply.
I A. Obtuse
B. Acute
C. Scalene
D.slught
E. Isosceles
F. Equilateral
Answer: B. Acute and F. Equilateral
Step-by-step explanation: Acute triangles contain interior angles that are less than 90 degrees. All triangles must have interior angles that add to 180 degrees when combined. In this triangle, all interior angles are equal. Therefore, we can divide 180 by the 3 angles to find that each angle is 45 degrees. 45 degrees is less than 90, so it is an Acute Triangle.
In equilateral triangles, all sides have the same length. We can see in the diagram that all of the sides contain the same marking, indicating they are the same length. So, the triangle is also equilateral.
Hope this helps!

If x = 3 and y = 5, work out the value of a) 4x - 2y
b) 2x2 + 3y2
Answer:
A) 12-10
B)36+225
Step-by-step explanation:
A) 3x4=12, 5x2= 10= 12-10
B) 3x2=6x6=36, 3x5=15x15=225=36+225
For x = 3 and y = 5 the values of the given expressions are (a) 4x - 2y = 2 and (b) 2x² + 3y² = 93.
What is substitution?Substitution is a mathemaical technique for replacing variables with specific or covnient values according to the context.
When the values of variables are given to solve an equation we just have to replace those numerical values in place of the given variables.
Given, x = 3 and y = 5.
∴ 4x - 2y is,
= 4(3) - 2(5).
= 12 - 10.
= 2.
And
2x² + 3y².
= 2(3²) + 3(5²).
= 2(9) + 3(25).
= 18 + 75.
= 93.
