Answer:
3:5 = 30:50 because it is ratio 3 x 10 = 30 5 x 10 = 50
Answer:
77
Step-by-step explanation:
Percentage of Fiction books
= 100% - 20% - 25%
= 55%
Number of Fiction books
= 55/100 × 140
= <u>7</u><u>7</u>
There are <u>7</u><u>7</u><u> </u><u>F</u><u>i</u><u>c</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>B</u><u>o</u><u>o</u><u>k</u><u>s</u>
(0,0)(12,84)
slope = (84 - 0) / (12 - 0) = 84/12 = 7
it goes thru the origin (0,0) therefore, the y int = 0
In y = mx + b form, the slope will be in the m position and the y int will be in the b position.
ur equaton is : y = 7x + 0, which can also be written as y = 7x <==
