You just have to multiply each number by 180 and that's how many you have of each color respectively

R + B = 5/7 x 180
R + B = 900/7 = 128, 4/7
If R = B than R is 450/7 = 64, 2/7
R or B = 64, 2/7

Please solve, -37-2v= -6(2v-3)-5

dezoksy [38]

Answer:

$\huge\boxed{v=5}$

Step-by-step explanation:

$-37-2v=-6(2v-3)-5\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\-37-2v=(-6)(2v)+(-6)(-3)-5\\\\-37-2v=-12v+18-5\\\\-37-2v=-12v+(18-5)\\\\-37-2v=-12v+13\qquad\text{add 37 to both sides}\\\\-37+37-2v=-12v+13+37\\\\-2v=-12v+50\qquad\text{add}\ 12v\ \text{to both sides}\\\\-2v+12v=50\\\\(-2+12)v=50\\\\10v=50\qquad\text{divide both sides by 10}\\\\\dfrac{10v}{10}=\dfrac{50}{10}\\\\v=5$

Please help me on this question

Nastasia [14]

Answer:

it would be A

Step-by-step explanation:

you have to find angle C first so you would subtract 105 from 180 to get 75 and then to find angle B you would add 75 and 55 to get 130 and since its a triangle it always has 180 degrees so do 180 - 130 to get 50

!!!! Which equation represents the graph shown? PLEASE HELP ASAP!!!

Julli [10]

Answer:

y= 2x +1

Step-by-step explanation:

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the gradient and c is the slope.

Since all the slope in the options are the same, let's focus on the y-intercept. From the graph, the line cuts through the y-axis at y= 1. Thus, the y- intercept is 1.

Hence, y= 2x +1 is the correct option.

Extra notes:

$\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }$
