Answer:

y = -11

Step-by-step explanation:

y - 3 (2y - 7) = 76

distribute the three to the two values in the parenthesis!

y - 6y + 21 = 76

now combine like terms, baiscally add y to -6y

-5y + 21 = 76

now subtract 21 from both sides

-5y = 55

then divide by negative 5

y = -11

Jared has a wooden board that is 11 ft long. He wants to cut it into 2 pieces so that the longer piece is 4 ft less than 4 times
Kaylis [27]
X+y=11

x is longer than y
x>y
x is 4 less than 4 times y
x=-4+4y

sub back
x+y=11
-4+4y+y=11
-4+5y=11
add 4 to both sides
5y=15
divide both sides by 5
y=3

sub back
x=-4+4y
x=-4+4(3)
x=-4+12
x=8

the pieces are 8ft and 3ft

Which equation can be used to find the unknown length, b, in this triangle?
Romashka-Z-Leto [24]

The equation for finding the hypotneus of a right triangle is
{a }^{2}  +  {b}^{2}  = c {}^{2}
so we know that 4²+b²=5²
so that would simplify as 16+b=25
so x=25-16
which is 9
so therefore we can conclude that
b = 9inches
