Answer:
125=12x+40
Step-by-step explanation:
Let the number of hours be x
And the total amount be =$125
We already have $40
Hence the expression is
125=12x+40
If we solve for x, the answer gotten is the number of hours
Answer:
17 512 dm3 27 28 dm3 37 43 dm3 47 52 92 cm3 57 42 m3
Step-by-step explanation:
17 volume= 8x8x8= 512 dm3
27 volume= 3.5x4x2= 28m3
37 volume= 4x2, 5x4.3= 43 dm3
47 volume= 18x14x21= 5292 cm3
57 volume= 4x3x3.5= 42 m3
the volume cuboid = length x width x height )
Answer:
p=5
Step-by-step explanation:
3p-7+p=13
Add like terms.
3p+p-7=13
4p-7=13
Add 7 to both sides.
4p-7+7=13+7
4p=20
Divide 4 from both sides.
=
p=5

Answer:
Step-by-step explanation:
Top triangle:
The hash marks indicate congruence. So, x is congruent to 15 or x= 15
x+6= 21
The length of the sides of this triangle are 15,15, and 21.
Two sides are congruent so isosceles.
Bottom triangle:
The sum of the angles in a triangle is 180.
30+35+x=180
75+x=180
x=105
105> 90, so this is an obtuse triangle.
