Answer:
Step-by-step explanation:
Let B be the number of black cars and S the number of silver.
We know that B/S = 7/4
We also know that B - S = 12
Rearrange the first: B = 7S/4
B - S = 12
7S/4 - S = 12
7S - 4S = 48
3S = 48
S = 16
B/S = 7/4
B/16 = 7/4
4B = 112
B = 28
B + S = 44 cars
I can't add the tape diagram here, but show two ribbons (tapes) for each car color and drawn so one can see the relative numbers of each.
The output value is multiplied by 4
Answer:
<em>84 centimeters of the width of the item in reality</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
<em>1. Given the information, let us create a proportionality as such:</em>
1 = 14 ⇒ x - width of item in reality (cm)
6 x
<em>2. Now let us cross multiply, and solve through simple algebra:</em>
14 * 6 = x,
<em>x = 84 centimeters of the width of the item in reality</em>
(-4) X (-8) = (32)...
=>Always remember in multiplying integers when both the signs are negative(-) then u multiply and put the positive(+) sign ...the product would be positive....=>and when both have positive (+) sign ,u multiply and put the plus sign ...=>and when both are different ,one positive(+) and other negative(-) then u multiply and put the negative(-) sign....(the same rules are followed in divisions also)....
=>So here the answer is option D(32) ...
