If 5x - 2y = 30, x = 2/5y + 6. 5x = 2y + 30. X=2/5y+6.
Hey There!
Cross multiply on both sides, with this you will be cross multiplying in order to set the numbers up.
s * 2.4 = 2.4s
2.8 * 6 = 16.8
2.4s = 16.8
Divide s from both sides:
16.8/2.4
<u>The answer is 7 or s= 7</u>
C is the y intercept of the line
Answer:
162 pups are on the beach
Step-by-step explanation:
9/20 of 360
The key word "of" tells us to multiply
Variable x = number of pups
9/20 × x/360
Cross multiply
9 × 360 = 20 × x
3,240 = 20x
Divide both sides by 20
162 = x
Check our work:
9/20 = 162/360
Cross multiply
9 × 360 = 20 × 162
3,240 = 3,240
Correct
