Step-by-step explanation:
-2x - 4 + 5y = 8
-2x + 5y = 8 + 4
-2x + 5y = 12

The measure of the angles in bold are as follows;
25. 90° and 90°
26. 60° and 60°
<h3>How to find angles?</h3>
When two parallel lines are cut by a transversal , angle relationship are formed. They are alternate angles, corresponding angles etc.
Therefore,
x + 96 + x + 96 = 180
2x = 180 - 192
2x = -12
x = -6
Hence, the angles are 90 and 90 degrees.
6x = 5x + 10(corresponding angles)
6x - 5x = 10
x = 10
Therefore, the angles are 60 degrees and 60 degrees

Answer:
150 degrees or 210 degrees
Step-by-step explanation:
A circle is equal to 360 degrees. The face of a clock is a circle and therefore 360 degrees. A clock is separated into 12 sections. Divide 360/ 12 = 30 degrees. This means each section is 30 degrees.
Between 2:00 and 7:00 clockwise, there are 5 sections. Since each section is 30 degrees, then 5*30 = 150 degrees.
Between 2:00 and 7:00 counter clockwise, there are 7 sections. Since each section is 30 degrees, then 7*30 = 210 degrees.
The angle depends on the direction of it.
let's call airplanes "a" and helicopters "h".
The total number of models is 35. This means that a+h=35
4 times as many model airplanes as model helicopters. This means a=4h.
we can substitute this into the previous equation:
4h+h=35
5h=35
dividing by 5:
h=7
so he has 7 helicopters and 4*7=28 airplanes
