Hi there!
[tex]\large\boxed{x = 16}[/tex]
.5x + 3 = 11
To begin, we can subtract 3 from both sides:
.5x + 3 - 3 = 11 - 3
.5x = 8
To cancel out the .5, we must multiply both sides by 2: (.5 × 2 = 1)
2(.5x) = 2(8)
x = 16.
answer choices:
A) 14.1 cm
B) 18.8 cm
C) 37.7 cm
D) 75.4 cm
Answers
Answer:
B. 18.8cm
Step-by-step explanation:
Circumference = π x Diameter
The given diameter here is 6cm and we need to use 3.14 for π so:
Circumference = 3.14 x 6
Circumference = 18.84 = 18.8 (1.d.p)
Therefore B is correct.

How many degrees is angle y
Answers
Answer:
y = 39°Steps:
w = 180 - (85+42) = 180 - 127 = 53°
y = 180 - (88+w)
y = 180 - (88+53)
y = 180 - 141
y = 39°
Answer:
y = 39
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of both triangles , then
x = 42 + 85 = 127
and
y + 88 = 127 ( subtract 88 from both sides )
y = 39
