If William has 195 marbles, let's find 4/5 of that.
195 * 4/5 = 156
156 is 2/5 of the marbles Daniel has.
Now we must multiply by the reciprocal
156 * 5/2 ( to find all of Daniel's marbles, not just 2/5) = 390 marbles
Daniel has 390 marbles.
Answer:
B) { 51, 149, 140 }
C) { 16, 63, 65 }
Step-by-step explanation:
We need to choose Pythagoras theorem formula

now, we can verify each options
option-A:
a=1
b=1
c=1
now, we can verify formula


We can see that left side is not equal to right side
so, this is FALSE
option-B
a=51
b=140
c=149
now, we can verify formula


We can see that left side is equal to right side
so, this is TRUE
option-C
a=16
b=63
c=65
now, we can verify formula


We can see that left side is equal to right side
so, this is TRUE
option-D:
a=6
b=8
c=11
now, we can verify formula


We can see that left side is not equal to right side
so, this is FALSE
Reta a:

reta x:

Retas paralelas possuem coeficientes angulares iguais ⇒ mₐ=mₓ

(-4,-2)

∴
y=3/4x+1
Answer:
y = 2
Step-by-step explanation:
20y - 21 = 10y - 1
20y = 10y + 20
10y = 20
y = 2
