X+y+z=62
second number (y) is equal to the first (x) diminished by 4 means
y=x-4
third (z) is 4 times the first (x) means
z=4x
sub 4x for z and x-4 for y
x+x-4+4x=62
add like terms
6x-4=62
add 4 to both sides
6x=66
divide both sides by 6
x=11
sub
y=x-4
y=11-4
y=7
z=4x
z=4(7)
z=28
the numbers are 11,7,28
the numbers are represented by n; n-4; 4n, first choice
Answer:
12
Step-by-step explanation:
5+7=12
5 have 7-14
7 have 15-22
The final answer is 12
To find the approximate length of the radius, you will use the formula for finding the circumference of a circle and solve for the radius (r).
C = 2 x pi x r
55 = 2 x 3.14 x r
<u>55 </u>= <u>6.28 x r</u>
6.28 6.28
r = 9.2 mm
The approximate radius is 9.2 mm.
The answer is D to the next step
