Answer:
On a coordinate plane, a straight line with a positive slope begins at point (0, 0), and ends at point (2.5, 5)
Step-by-step explanation:
The distinction between "straight line" and "blue diamonds" is that the straight line represents the relation for all possible values of x. The blue diamonds show the values of y for very specific values of x.
Since x is the amount of rice from a bulk bin, we assume it can take any non-negative value. Hence, the graphs with negative values or with "blue diamonds" are not appropriate.
The straight-line graph in the first quadrant is the best choice.
Answer:
ABCD = 0.803
Step-by-step explanation:
ABCD = 89.63 * (-89.63) * (-0.01) * (0.01)
ABCD = 0.803
Answer:
Altogether Gavin and Jim won £95.
Step-by-step explanation:
We are given the following in the question:
Ratio of money won by Gavin and Jim = 5:2
Gavin gets £39 more than Jim.
Let x be the amount of money Won by Jim.
Then, money won by Gavin =
Thus, we can write the equation:
Solving, we get,
Thus, Gavin won £65 and Jim won £26.
Money won altogether =
Thus, altogether Gavin and Jim won £95.
Answer:
4 nickels
12 dimes
Step-by-step explanation:
Dimes are worth .1 each while nickels are .05 each.
We have 8 more dimes than nickels. Let d represent number of dimes and n for number of nickels. This means we have d=8+n.
If all our nickels and dimes together are worth 1.4 then we have another equation .1d+.05n=1.4
Lets put our equations together:
d=8+n
.1d+.05n=1.4
‐-----------------Plug first equation into second.
.1(8+n)+.05n=1.4
Distribute
.8+.1n+.05n=1.4
Combine like terms
.8+.15n=1.4
Subtract .8 on both sides
.15n=.6
Divide both sides by .15
n=.6/.15=4
Remember there are 8 more dimes so d=8+4=12.
Answer:
$(8967/n + 8.4)
Step-by-step explanation:
0.4nx + 0.6n(x+21) = 8967
nx + 12.6n = 8967
x = 8967/n - 12.6
x+21 = 8967/n + 8.4
Where n is the no. of balls
Example: if total balls were 300
n = 300
More expensive one would cost:
8967/300 + 8.4 = $38.29
