What is the best approximation of the solution to the system to
the nearest integer values?
o
(3, 4)
o
(2, 3)
O (1, 3)
o (3, 2)
Answer: (2,3)
====================================================
Explanation:
The intersection point of the two lines is where the solution point is located.
The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.
At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.
So that's how we get to (2,3)

What are two ways to find the number of pencils James has?
O A. 16+3 and 16 x 3
B. 16 + 16 + 16 and 16 x 3
OC. 3+3 + 3 and 18 x 3
O D. 16 + 3 and 3 x 48
E. 3+3+ 3 + 16 and 16 X 3

How many degrees are in Arc AC?
Answer:
B. 120° degrees
Step-by-step explanation:
Inscribed angle ABC = 60°
Arc AC = 2 * < ABC (Relation between arc and inscribed angle)
Arc AC = 2 * 60°
= 120°
Answer:
120°Because, Angle ABC is incribed in arc AC .
We know that it's 2times than angle ABC.
THEREFORE, 60 × 2 = 120
Find the sine, cosine, and tangent of angle A. (fraction as in simplest form please.)
Answer:
SinA=3/5
CosA=4/5
TanA=3/4
Step-by-step explanation:
first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2
20^2-16^2=144 the square root of 144 is 12 so side length bc=12
so sin is opposite/hypotenuse
the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5
cos is adjacent/hypotenuse
the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5
tan is the opposite/adjacent
the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4
Victor has 2 fraction models.Each is divided into equal sized sections the models are shaded to represent the same fraction.Model A is divided into 6 sections and 3 sections are shaded.Model B is divided into 12 sections select the true statement
Answer:
Model B has 6 shaded sections
Step-by-step explanation:
The question is not complete. The complete question should be in the form:
Victor has 2 fraction models. Each is divided into equal sized sections the models are shaded to represent the same fraction. Model A is divided into 6 sections and 3 sections are shaded. Model B is divided into 12 sections. What do you know about the number of sections shaded in Model B? Explain your answer.
Solution:
The fraction modeled by model A is given by the ratio of shaded sections to the total number of sections.
That is Fraction of model A = number of shaded sections / total number of sections.
Hence:
Fraction of model A = 3 / 6
Since model B and Model A are equivalent, the number of shaded sections in Model A is given by:
number of shaded sections in model B/ total number of sections in model B = Fraction of model A
number of shaded sections in model B / 12 = 3 / 6
number of shaded sections in model B = 12 * 3/6
number of shaded sections in model B = 6

What are the measures of the angles in the triangle? A 60; 60; 60 B 78; 51; 51 (6x + 10º) C 34; 112; 112 D 112; 34; 34 (x + 179) (4x - 349) OA
Answer:
D
Step-by-step explanation:
x+17 = 4x-34
-3x = -51
x = 17
17+17= 34
The bottom two are equal so 34, 34
A triangle adds up to 180
180- 68 = 112
So the top is 112
After solving the equation for all three angles of a triangle, the angles are 34, 112, and 34. Hence, option C is correct.
What is a triangle?The basic polygonal shape of a triangle has three sides and three interior angles. It is one of the elementary objects in geometry and is represented as follows. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.
As per the given angles of a triangle in the question,
Let angle A = 6x + 10 (i)
Angle B = x + 17 and, (ii)
Angle C = 4x - 34 (iii)
The submission of all angles will be equal to 180°.
(6x + 10) + x + 17 + 4x - 34 = 180
11x = 187
x = 17
Substitute the value of x in equations to find the angle,
A = 6(17) + 10 = 112
B = 17 + 17 = 34
C = 4(17) - 34 = 34.
These are the angles obtained

Answer:
1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.
2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

Paulo and Marie are collecting quarters. The number of quarters Paulo has is 3 times 5 fewer than the number of quarters Marie has. Let m be the number of quarters Marie has. What expression represents the number of quarters Paulo has?
Answer:
Paulo = 3m - 5
Step-by-step explanation:
m = number of quarters Marie has
The number of quarters Paulo has is 3 times 5 fewer than the number of quarters Marie has
3 times number of quarters Marie has = 3 * m
= 3m
5 fewer than the number of quarters Marie has
3m - 5
Paulo = 3m - 5
