Answer:
L = 18 inches
Step-by-step explanation:
if s is side length
400 = s•s•4
s² = 100
s = 10
so the original flat cardboard square has sides of
L = 10 + 4 + 4
L = 18 inches
Answer:
The large number is 17
Step-by-step explanation:
x+y=31⟹x=31−y
2x=y+11⟹x=y+11/2
2(y+11/2)=2(31−y)
y+11=62−2y
3y=51
y=17 x=14
Hope this helps, have a nice day! :)
Use the equation:
76 * .8 + 61 * .2 = Final Grade
Answer:
<em>x-intercept = 1/8</em>
<em>y-intercept = -1/2</em>
Step-by-step explanation:
Let y = 0, and solve for x to find the x-intercept. Then let x = 0 and solve for y to find the y-intercept.
x-intercept
16x - 4y = 2
16x - 4(0) = 2
16x - 0 = 2
16x = 2
x = 2/16
x = 1/8
x-intercept = 1/8
y-intercept
16x - 4y = 2
16(0) - 4y = 2
0 - 4y = 2
-4y = 2
y = 2/-4
y = -1/2
y-intercept = -1/2
