Answer:
Assuming the scale is 1cm:50m then the answer is 150m
Step-by-step explanation:
1 cm is directly proportional to 50m so 3cm would be multiplied by 50m to find the answer. And 3 × 50 = 150
Answer: the number of pounds of Brown's Grounds Coffee that was mixed is 60
the number of pounds of Coffee From Heaven that was mixed is 40
Step-by-step explanation:
Let x represent the number of pounds of Brown's Grounds Coffee that was mixed.
Let y represent the number of pounds of Coffee From Heaven that was mixed.
Brown's Grounds Coffee is selling for $2.50 a pound is mixed with Coffee From Heaven selling for $2.80. 100 pounds was produced and sold at the rate of $2.62 per pound. This means that the total cost of the blend produced is 100×2.62 = $262. Therefore
2.5x + 2.8y = 262 - - - - - -- - -- - -1
x + y = 100
Substituting x = 100 - y into equation 1, it becomes
2.5(100 - y) + 2.8y = 262
250 - 2.5y + 2.8y = 262
- 2.5y + 2.8y = 262 - 250
0.3y = 12
y = 12/0.3 = 40
x = 100 - y = 100 - 40
x = 60
Answer: 113
Step-by-step explanation:
47+66=x
113=x
Answer:
y=13x-107
Step-by-step explanation:
(10- -3)/(9-8)=13
10=13*9+b
b=10-117=-107
You know the formula of discriminant
a b
c d
that means ad-bc
So <span>we have an equation
(-12)x3-(2f)x(-w</span>²)= 2k x 3- (-14)x(-81)
0r -36 +2fw²= 6k- 1134
And 2fw²-6k+ 1098=0
But I did not know what is variable here?
