Answer:
The answer is below
Step-by-step explanation:
A shop contained some refrigerators and televisions. The total number is 800, and 45% of them were refrigerators. If 60% of refrigerators were sold and 65% of televisions were sold last week. How many fewer refrigerators were sold than televisions?
Solution:
The number of refrigerators = 45% of 800 = 0.45 * 800 = 360 refrigerators.
The number of televisions = 800 - 360 = 440 televisions.
number of refrigerators sold = 60% of 360 = 0.6 * 360 = 216 refrigerators
number of televisions sold = 65% of 440 = 0.65 * 440 = 286 televisions
The number of fewer refrigerators that were sold than televisions = 286 - 216 = 70
Divide 21.2 by 100 then multiply by 1650650
Final answer— 349,937.8
Answer:
x - 7
Step-by-step explanation:
Let's let x = 4 and see which one would be different
x - 7 = 4 - 7 = -3
7 + (-x) = 7 + -4 = 3
-x + 7 = -4 + 7 = 3
7 - x = 7 - 4 =3
As you can see, the top answer would be negative while all the rest are positive. This is because, in that case, the negative sign was attached to the 7 instead of the x.
Three times the difference between t and y, if you don't know the values of either variable, is 3(t-y).
Answer:
y=2x
Step-by-step explanation:
Direct variation is such that y=kx where k is the rate of change. In direct variation the graph must cross the origin (0,0) meaning that the y-intercept is zero. The only equation that satisfies the definition of direct variation is y=2x.
