Answer:

Step-by-step explanation:
Given:
,
To find the value of y, let's find x by solving 3x = 15.
3x = 15
Divide both sides by 3
x = 15/3
x = 5
Plug in the value of x into 




Answer:
x = 9 m
y = 1 m
Step-by-step explanation:
6/1 = x/1.5
x = 1.5 × 6
x = 9
6/1 = 6/y
6y = 6
y = 1
If it's already a negative number it's going to stay as a negative number
Answer: C. X + 44
Step-by-step explanation:
Let x be the unknown number.
Given statement : "44 more than an unknown number".
By using addition operation ,
Mathematical expression for "44 more than an unknown number" = 44 +x
Hence, the correct expression is x+44.
So, the correct option is C.
Answer:
A = 1100cm^2
Step by step Explanation:
given the dimensions of width and length of the picture are x+20 by 2x-10 and the frame is a constant 5 cm wider from the edge of the picture to the frame, than the area of the frame is defined as (x+30)(2x)-(x+20)(2x-10) = 30x+200.
If the width is equal to the length which I assume is true if the width is constant.
than x+30=2x, which means x = 30.
if this is true than 30(30)+200 = 1100cm^2
