If Morgan is 15 years younger then Mrs.Santos and there combined age is 442 that means that Mrs.Santos is 221, and Morgan is 206.
Answer:
x = -2
y = 3
Step-by-step explanation:
from above equation we get ,
=》y = 3x + 9
now ,
by second equation,
=》2x + 3y = 5
=》2x + 3 × ( 3x + 9 ) = 5
( since, y = 3x + 9 , by equation 1 )
=》2x + 9x + 27 = 5
=》11x = -22
=》x = -2
putting value of x in equation 1 ;
=》 y = 3x + 9
=》 y = 3 × ( -2 ) + 9
=》 y = -6 + 9
=》 y = 3
Answer:
It has more than one equal sign but set up like this:
Step-by-step explanation:
Let's solve for x.
y+x−1+
3
2
=−y
Step 1: Add -y to both sides.
x+y+
1
2
+−y=−y+−y
x+
1
2
=−2y
Step 2: Add (-1)/2 to both sides.
x+
1

=−2y+

x=−2y+

Answer:
x=−2y+
-1/2
The zero product property means that 0a=0.
(I'm assuming that by y2 you mean y squared btw)
the zero divided by y is zero:
move the 4y
Hope that helps!
Answer:
32°, 58°
Step-by-step explanation:
Let one acute angle measure x.
The other acute angle measures 2x - 6.
The sum of the measures of the acute angles of a right triangle is 90.
x + 2x - 6 = 90
3x - 6 = 90
3x = 96
x = 32
2x - 6 = 2(32) - 6 = 58
Answer: 32°, 58°
