for the equation <em>5x−7y=58 </em> for <em><u>x</u></em>=7/5y+58/5 for <em><u>y</u></em> 5/7x+−58/7
for the equation y=−x+2 x= −y+2 for y= −x+2
Answer:
why
Step-by-step explanation:
Use proportions to find the height of the building-
=
The x is the height of the building.
It is over 1 (the height of the other building) because both are heights.
Similar triangles are in proportion so the other fraction is in proportion to it.
Cross multiply(x times .2) (8 times 1). You will get this equation-
.2x=8
Solve for x by dividing-
x=40
Since this was done in meters, the answer is-
The building is 40 meters.
17
85/17 is 5 and 51/17 is 3
So you first subtract 26 by four giving you 22 then divide it by 2 for the two girls and your answer is ....... 11!!!!!!!!!!!!
