Answer:
Solve for y 3/7=15. 37y=15 3 7 y = 15. Multiply both sides of the equation by 73 7 3. 73.37 y=73.15 7 3. 3 7 y = 7 3. 15
Step-by-step explanation:
Solve for y by simplifying both sides of the equation, then isolating the variable. Y=35
It's about simple interest and which is very easy to solve
Simple Interest
Where
P=500
R=3
T=8
S.I=P.R.T/100
S.I=500*3*8/100
S.I=12000/100
S.I=120 $
So answer is 120$ interest will he earn in 8 year

Answer:
y = 7/3x +13/3
Step-by-step explanation:
The equation of the given line is in slope-intercept form (y=mx+b), so we can see the slope (m) is -3/7. The slope of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/(-3/7) = 7/3
The y-intercept of the perpendicular line can be found from ...
b = y -mx
b = -5 -(7/3)(-4) = -15/3 +28/3 = 13/3
Then the slope-intercept equation of the perpendicular line is ...
y = mx +b
y = 7/3x +13/3
_____
<em>Additional comment</em>
You can get there a little faster using the point-slope form of the equation of a line. For slope m and point (h, k) that form is ...
y -k = m(x -h)
For our perpendicular line, the equation is ...
y +5 = 7/3(x +4)
Step-by-step explanation:
Convert the fractions in the yards given to decimals, because then you can divide the length of the sidewalk by the length of each tile. So 2/5 is 2 divided by 5 which equals .4. And 1/8 is 1 divided by 8 which is .125.
So, the sidewalk is 14.4 yards long and each tile is 1.125 yards long.
Divide the length of the sidewalk, 14.4 yards, by the length of each tile, 1.125 yards.
Equals 13.8 tiles, rounded off to 14 tiles.
Hope this helps.
14 2/5 = 72/5
1 1/8 = 9/8
72/5 = 576/40 divide by 45/40 = 576/40 x 40/45 = 23040/1800 = 12.8 tiles
15/16, 7/8, .8
because 7/8=0.875 and .875>.8
15/16 = 0.9375
0.9375> 0.875 > .8
