Answer:
cost of tacos=$2
cost of soda=$1
Step-by-step explanation:
x=price of tacos
y=price of soda
3x+y=7 --> y=7-3x
4x+2y=10 --> y=5-2x
5-2x=7-3x
x=2
y=5-2(2)=1
Answer:
It would be 3 dollars.
Step-by-step explanation:
Because you do 3x2 which is the closest to 7 so that means you do 6/3 which is 2 and that means each taco cost 2 dollars and 1 soda is 1 dollar.

hari purchased a camera for rs 1560 and sold ot at 5% loss. find hos loss amount
Answer:
[tex]SP = 1482[/tex]
Step-by-step explanation:
Given
[tex]CP = Rs. 1560[/tex] --- Cost Price
[tex]Loss = 5\%[/tex]
Required
Determine the selling price (SP)
This is calculated using:
[tex]\%Loss =\frac{CP - SP}{CP} * 100\%[/tex]
So, we have:
[tex]5\% = \frac{1560 - SP}{1560} * 100\%[/tex]
[tex]5 = \frac{1560 - SP}{1560} * 100[/tex]
Multiply through by 1560
[tex]1560 * 5 = \frac{1560 - SP}{1560} * 100*1560[/tex]
[tex]1560 * 5 = (1560 - SP) * 100[/tex]
[tex]1560 * 5 = 1560 * 100- SP * 100[/tex]
[tex]7800 = 156000- 100SP[/tex]
Collect Like Terms
[tex]100SP= 156000- 7800[/tex]
[tex]100SP= 148200[/tex]
Make SP the subject
[tex]SP = \frac{148200}{100}[/tex]
[tex]SP = 1482[/tex]
The selling price is Rs. 1482

Which of the following equations is true? 0.3+1 = 3.0 O 6.1.0 = 6 + 1 + 0 7.1= 0 +7 = 1+1=1:1
Answer:
6 + 1 + 0 7.1= 0 +7 = 1+1=1:1
Step-by-step explanation:
The only true equation is 7 . 1 = 0 + 7.
Define equation? What is Equation Modelling?
Equation is defined as a relation that equates two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given are the following equations -
0 . 3 + 1 = 3.0
6.1.0 = 6 + 1 + 0
7.1 = 0 + 7
1 + 1 = 1 : 1
We have -
0 . 3 + 1 = 3.0
0 x 3 + 1 = 3 x 0
0 + 1 = 3 x 0
1 = 0
false
6 . 1 . 0 = 6 + 1 + 0
6 x 1 x 0 = 7 + 0
0 = 7
false
7 . 1 = 0 + 7
7 x 1 = 7
7 = 7
true
1 + 1 = 1 : 1
2 = 1/1
2 = 1
false
Therefore, the only true equation is 7 . 1 = 0 + 7.

Answer:
3: D) 11
4: D) 12
7: C) 63
8: A) Adjacent Angles
Step-by-step explanation:
Let's pretend the sides of a triangle are A B and C.
The third side of a triangle is always greater tham A-B and lesser than A+B. This is called the triangle inequality theorem.
For 7 and 8, we have three lines that come together at one point (adjacent angles), and the vertical angle postulate where two mirrored angles will always have the same angle.

A pharmacist has a 12% solution and a 20% solution of boric acid. How much of each should she use to make 80 grams of a 15% solution?
Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
Since we need 80 grams of 15%, 80(.15) = 12.
We are given that .12x + .20y = 12.
We can solve the first equation for x or y. Let's do x.
x = 80 - y
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
y = 30
x = 80 - 30 = 50
Answer:
50 grams

Which of the following is equivalent to the complex number i^34 ?
Choose 1 answer:
А
1
B I
C
-1
D
-I
Given:
The complex number is [tex]i^{34}[/tex].
To find:
The value of given complex number.
Solution:
We have,
[tex]i^{34}[/tex]
It can be written as
[tex]i^{34}=i^{32+2}[/tex]
Using properties of exponents, we get
[tex]i^{34}=i^{32}i^{2}[/tex] [tex][\because a^{m+n}=a^ma^n][/tex]
[tex]i^{34}=i^{4\times 8}i^{2}[/tex]
[tex]i^{34}=(i^4)^8i^{2}[/tex] [tex][\because (a^{m})^n=a^{mn}][/tex]
We know that, [tex]i^4=1,i^2=-1[/tex].
[tex]i^{34}=(1)^8(-1)[/tex]
[tex]i^{34}=(1)(-1)[/tex]
[tex]i^{34}=-1[/tex]
The value of [tex]i^{34}[/tex] is -1. Therefore, the correct option is C.
Simplify. Multiply and remove all perfect squares from inside the square roots.

Which angle must also measure 85°?
O 2
O 5
O11
0 12
Answer:
11
Step-by-step explanation:
11 has 85° because it is opposite to 9
The angle that must also be measured of 85° is angle 11.
Option C is the correct answer.
What is an angle?The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.
Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.
We have,
In the diagram,
∠9 = 85
This means,
∠9 and ∠11 are opposite angles.
And,
Opposite angles are equal.
So,
∠9 = ∠ 11 = 85
Thus,
The measure of angle 11 is also 90.

Find the measure of angle x in the figure.
Answer:
x = 124°
Step-by-step explanation:
The polygon given is a 7-sided polygon with 7 interior angles.
Sum of all 7 interior angles of the polygon = (n - 2)*180, where n = 7, we would have the following equation:
131° + 131° + 126° + 118° + 134° + 136° + x° = (7 - 2)*180
776 + x = 900
Subtract 776 from each side
x = 900 - 776
x = 124°
