Answer:
No.. i dont think its wrong.
Step-by-step explanation: Spiders protect frogs for protection.
X + y = 90
y = 90 - x
0.15 x + 0.75 y = 0.51 (90)
0.15 x + 0.75 (90-x) = 0.51 (90)
0.15x + 67.5 -0.75x = 45.9
21.6 = 0.6 x
x = 36 kg -- 15% Cu
y = 90 - x
y = 90 - 36
y = 54 kg -- 75% Cu
Answer:
Ralph had 600 tomato plants in the beginning.
Step-by-step explanation:
Consider the provided information.
let x is the number of units.
The number of tomato plants in Inessa's garden is 5x
The number of tomato plants in Ralph's garden is 6x
It is given that half of Inessa's tomato plants are taken from her garden and replanted into Ralph's garden.
Therefore,
1/2 × (5x)
After replanted Ralph’s garden had 850 tomato plants.
Therefore,
(1/2)(5x) + 6x = 850
5x + 12x = 1700
17x = 1700
x = 100
The number of tomato plants in Ralph's garden is 6x.
Substitute the value of x in 6x.
6(100)=600
Hence, Ralph had 600 tomato plants in the beginning.
Answer:
a) The difference of a number and six is no less than 15
x - 6 ≥ 15
b) 25 plus a number is at least 13
25 + x ≥ 13
c) g decreased by 25 is at most five
g - 25 ≤ 5
Step-by-step explanation:
a) The difference of a number and six is no less than 15
Let the number be represented by x
We difference is involved in a mathematics question, it requires the application of Subtraction operation, hence:
x - 6 ≥ 15
b) 25 plus a number is at least 13
Let the unknown number be represented by x
When at least is used in Mathematics, is means greater than or equal to a particular value,
Hence,
25 + x ≥ 13
c) g decreased by 25 is at most five
At most means less than or equal to a particular value, hence:
g - 25 ≤ 5
