Answer:
10w ≥ 30
Step-by-step explanation:
First, the variable w represents the "sum of a number and 15", so we don't know the missing value. Therefore the first part is 10w. The inequality is ≥ because it represents "at least 30". Your inequality should be 10w ≥ 30
Hope this helps!
Answer:
1. $11.50 2a. 25 2b. Decrease by 10
Step-by-step explanation:
1. Let's write Marietta's wage before a raise as x
$12.25 = x + $0.75
$12.25 - $0.75 = x
x = $11.50
2a. Let's substitute p with the actual value ($170)
170 = 8n - 30
200 = 8n
n = 200/8 = 25
2b.
p = 8*25 - 40
p = 200 - 40 = 160
160 < 170 so the profit decreased
It decreased by 10 (170 - 160).
Answer:
= 52°
Step-by-step explanation:
The obtuse angle at O is twice the angle made at the circumference /by the same segment b.
=52×2=104°
The base angles that are made by isosceles triangle that has the apex with angle 104° equal to (180-104)/2=38°
The radii of a circle are equal and meet tangents at right angles.
Angle a= 90-38= 52°
