The 2 angles are complementary angles and need to equal 90 degrees.
Making an equation we have:
4x-10 + x = 90 degrees
Add like tems:
4x +x = 5x
Now we have:
5x-10 = 90
Add 10 to both sides:
5x = 100
Divide both sides by 5:
x = 100/5
X = 20
Answer:
21; the age of the teacher
Step-by-step explanation:
15+x/2=18
Estimate - I estimated in the 20's because it only averaged up a little bit
Started with 23 and kept going until i got to my answer
21
15+21/2
36/2
18
Please mark brainliest :)
M-(M x 0.16) and M-(.84) because the first one you need to multiply to find what 16% of m is then subtract that by m for the second one you subtract.
D: 11x + 12, you just add all of the x values together and you’re set.
Answer:
(6,0)
Step-by-step explanation:
If the y-coordinate is 0, it is lying on the x-axis
Same with the x-coordinate. If it is 0, it is lying on the y-axis
