Answer:
-1/4-(-3/5)=0.35
Step-by-step explanation:
7+3x=2x+2
Send constants to one side and others to one side
3x-2x=2-7
x=-5
Answer:
H= 121.25 meters
Step-by-step explanation:
To find the value of H after 30 months given the equation H=0.20x+115.25,
replace x by 30 in the equation and solve;
H=(0.20*30)+115.25
H=6+115.25
H= 121.25 meters
Therefore, the height will be 121.25 meters
9514 1404 393
Answer:
x = 2
y = 9
Step-by-step explanation:
Opposite sides of a parallelogram are the same length. This relation is used to make equations with the given side lengths.
<u>Top and Bottom</u>
4x +20 = x +26
3x = 6 . . . . . . . . . . . subtract x+20 from both sides
x = 2 . . . . . . . . . divide by 3
<u>Left and Right</u>
7y = 6y + 9
y = 9 . . . . . . . . . subtract 6y from both sides
