<h3>1. Write the expression.</h3>

<h3>2. Substitute y for x, and x for y.</h3>

<h3>3. Solve for y.</h3>

<h3>4. Express your result.</h3>
.
B 3/7 because 15 divided by 5 = 3 and 35 divided by 5 = 7
-7(x+y=525)-7
3x+7y=2775
-7x-7y=-3675
3x+7y=2775
-4x=-900
X=-900/-4
X=225
Answer is c
Answer:
40 degrees
Step-by-step explanation:
Complementary angles have a sum of 90.
y = 90 - x
The angle is 260 degrees less than six times its complement.
y = 6x - 260
90 - x = 6x - 260
350 - x = 6x
350 = 7x
50 = x
This is the measure of the complement.
y = 90 - x
y = 90 - 50
y = 40
This is the measure of the first angle.
