Answer:
x=12
10x = 120
5x = 60
Step-by-step explanation:
paralellograms will become 360 degrees
so 2(5x) +2(10x)= 360
Simplify:
10x + 20x = 360
= 30x
divide both sides by 30 and isolate
<u>30x </u> = <u>360</u>
30 30
x=12
multiply 12 by 10x and 5x
10x = 120
5x = 60
Answer:
Step-by-step explanation:
Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.
4x+3x+13=90
-13 -13
7x=77
/7 /7
X=11
Now plug in the value of x.
A=4(11) B=3(11)+13
A=44. B=33+13
B=46
Angle a is the smaller angle and measures at 44°

Step-by-step explanation:
Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
Solve. −3/5x+1/5>7/20 Drag and drop a number or symbol into each box to show the solution
we have
Solve for x
Multiply by 20 both sides
subtract 4 both sides
divide by -12 both sides
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
simplify
