75 + 50x = 25 + 70x<br><br> a, 5<br> b, 5/6<br> c, 2<br> d, 2.5
Stells [14]

Answer:

D

Step-by-step explanation:

Let's solve your equation step-by-step.

75+50x=25+70x

Step 1: Simplify both sides of the equation.

50x+75=70x+25

Step 2: Subtract 70x from both sides.

50x+75−70x=70x+25−70x

−20x+75=25

Step 3: Subtract 75 from both sides.

−20x+75−75=25−75

−20x=−50

Step 4: Divide both sides by -20.

−20x

−20

=

−50

−20

x=  5/2

Three houses are mapped on a coordinate grid.
Licemer1 [7]

Step-by-step explanation:

Let us consider the task to find the angle between vectors ES and EJ (the first letters are taken to name the vectors).

\overrightarrow{ES} = (4;4) - (4; -3) = \overrightarrow{(0; 7)}

ES

=(4;4)−(4;−3)=

(0;7)

​

\overrightarrow{EJ} = (-5; -4) - (4; -3) = \overrightarrow{(-9; -1)}

EJ

=(−5;−4)−(4;−3)=

(−9;−1)

​

cos \alpha=\frac{\overrightarrow{ES}*\overrightarrow{EJ}}{|\overrightarrow{EJ}|*|\overrightarrow{ES}|}cosα=

∣

EJ

∣∗∣

ES

∣

ES

∗

EJ

​

cos(a) = (0*(-9)+7*(-1)) / (7*9.055) = -0.11043;

a = 96,34°

Solution: 96 degrees.
