Answer:
<em>start with g </em>
g
<em>subtract 7</em>
g-7
<em>multiply by 3</em>
3(g-7)
<u>Therefore the expression is </u>
3g-21
If two lines are perpendicular, the statement that must be true is : D. The product of their slopes is -1
Lets say that a line has a slope of 2, the line which perpendicular to that line would have a slope of -1/2
Which means, the product would be 2(-1/2) = -1
hope this helps
Answer:
21/25 = 84/100
17/20 = 85/100
21/25 < 17/20
Step-by-step explanation:
∵ The common multiple of 25 and 20 is 100
∵ 100 ÷ 25 = 4
∴ 21/25 = (21 × 4)/(25 × 4) = 84/100
∵ 100 ÷ 20 = 5
∴ 17/20 = (17 × 5)/(20 × 5) = 85/100
∵ 84 < 85
∴ 84/100 < 85/100
∴ 21/25 < 17/20
