Answer:

C. Infinite solutions

Step-by-step explanation:

I'll use the equal value method and make the second equation equal 6 instead of 18, so I have to divide the entire equation by 3

(6x+15y=18)/3 = 2x +5y = 6

The second equation is the same thing as the first one, meaning no matter what value they will equal the same thing, also meaning there are infinite solutions

Answer:

0.48

Step-by-step explanation:

Given the data:

10,17,20,23,24,28,32,39,42,25,26,52,55,58,61,65,66,72,75,78,79,85,94,97,98

Sum of each of the numbers :

1, 8, 2, 5, 6, 10, 6, 12, 6, 7, 8, 7, 20, 13, 7, 11, 12, 9, 12, 15, 16, 13, 13, 16, 17

Probability that sum of the number's digit is odd:

Number of odd sum / total numbers

Number of odd sum = 12

Total numbers = 25

12 / 25

= 0.48

What’s the measure of the angle theta?

11111nata11111 [884]

Answer:

∅ = 50°

Step-by-step explanation:

YOU NEED A CALCULATOR TO SOLVE THIS!

You need to use Law of Sines

$\frac{a}{sinA} =\frac{b}{sinB} = \frac{c}{sinC}$

Here you will be doing $\frac{a}{sinA} =\frac{c}{sinC}$

a and c are the lengths, while A and C are the angles

$\frac{3.46}{sinA} = \frac{2.54}{sin43}$ you want to get the denominators out from underneath so multiply both sides by sinA and sin43

$3.46sin43 = 2.54sinA$

Now you want to get sinA alone so divide both sides by 2.54

$\frac{3.46sin43}{2.54} = sinA$ now get A alone

$sin^{-1} (\frac{3.46sin43}{2.54}) = A$ put that into the calculator

$49.61741033 = A$

Determine which statement is a true proportion.

Ratling [72]

The answer is option B. 11/12 = (13 3/4) /15

it could be considered a true proportion if both are equal in values.

In order to find this, you need to cross multiply the numerator and the denominator in all of those options and find which give the exact result.

11 x 15 = 13 3/4 x 12
