Answer:
x = 50
Step-by-step explanation:
The legs are perpendicular and so the triangle is a right triangle.
Using the Pythagorean Theorem, we get
48^2 + 14^2 = x^2 = 2304 + 196 = 2500. Then x is the positive square root of 2500, which is 50.
x = 50
Answer:
box contains - 3
Step-by-step explanation:
a(x - 3) + 2x = -(x - 5) +4 Remove the brackets on both sides
ax - 3a + 2x = -x + 5 + 4 Subtract 2x from both sides.
ax - 3a + 2x - 2x = -x - 2x + 9
ax - 3a = - 3x + 9
ax - 3(-3) = - 3x + 9
ax + 9 = - 3x + 9
Now if you make a = -3 then both sides with have - 3 for the x coefficient.
Any number could be put in for x and it will make the answer on both sides equal. Notice you could subtract 9 from both sides and it will not change the condition of the problem.
Answer:
141
Step-by-step explanation:
162+54-75=141
First, move the decimal place from the 22% so it would be .22 multiply that by 4,000 that would be 880 add that to 4,000 so 4,880 50% of that would be .50x4880= 2440 subtract that from 4,880 so 4,880-2,440=2,440
In November they sold 4,000
In December they sold 4,880
In January they sold 2,440
add these together and in the 3 months the company sold 11,320 cell phones. :)
