Richard and Teo are 7 and 24.
7 times two is 14
24 is ten more than 14
31-7 is 24
20=x/3-8
28=3x
3x/3 = 28/3
X= 28/3
Step-by-step explanation:
Equations:
Quantity:: d = n + 3
Value::: 10n + 5d = 615 cents
-------------------------------------------
Modify::
d - n = 3
d + 2n = 123
--------------------------------------------
Subtract and solve for "n"::
3n = 120
n = 40 (# of nickels)
d = n+3 = 43 (# of dimes)
Answer:
y=1x +8
5
Step-by-step explanation:
y-y1 = m(x-x1)
y+2 = -5(x-2)
y+2 = -5x + 10
y = -5x +8
Now to find line L we have to change the slope because it is perpendicular
y= 1x +8 (The slope is one fifth, but idk
5. to put it, I'm sorry)
