-4y-3x= -11
-2x+4y= -34
-4y-3x-2x+4y= -11-34
-5x= -45
x=9
9-2y=17
y= -4
Answer:
5cm
Step-by-step explanation:
Given parameters:
Volume = 45cm³
Radius = 3cm
Unknown:
Height of the cone = ?
Solution:
Volume of cone is given as ;
V =
r² h
r is the radius
h is the height
45 =
x 3² x h
45 = 3π x h
h =
= 4.77cm
5cm is the closest answer choice

5m + 3n + p
-5p + 3n
2n - m
Arrange them in like terms
5m + 3n + p
+ 3n - 5p
add; <u>-m + 2n
</u> 4m + 8n - 4p Choice No. 4.<u>

Answer:
m∠A = 59°
Step-by-step explanation:
Supplementary angles mean that, when the two are combined, their total measurement will equal 180°.
It is given that one of the angles is 121°. Subtract 121 from 180:
180 - 121 = 59
m∠A = 59°
