Let's say that the weight of the orange is x and the weight of the pineapple is y.
The weight of the pineapple is 7 times that of the orange, so
y = 7x.
Also, y = x + 870.
Therefore, 7x = x + 870.
If we take away x from both sides, we get 6x = 870
If we divide both sides by 6, we get x = 145.
Therefore, the weight of the orange is 145 g.
Also, 145 + 870 = 1015.
So the weight of the pineapple is 1015 g.
To convert grams into kilograms, they must be divided by 1000.
Therefore, the weight of the orange in kilograms is 145/1000 = 0.145 kg
And the weight of the pineapple is 1015/1000 = 1.015 kg.
Answers:
a. 145g for the orange and 1015g for the pineapple.
b. 0.145kg for the orange and 1.015kg for the pineapple.
Answer:
x = 29°
y = 29°
z = 102°
Step-by-step explanation:
x and y both look even to the 29° angle across from them and z looks even to the 102° angle across from it.
Answer:
The ML draw up = 1.2 ML
Step-by-step explanation:
we are told that concentration of Ceftriaxone = 1g/ 9.6ML
This means that:
9.6 ML contains 1g ceftriaxone
1g = 9.6 ML
note also that 1g = 1000mg
∴ 1000mg = 9.6 ML
∴ 1mg = (9.6 ÷ 1000) ML
1mg = 0.0096 ML
∴ 125 mg = 125 × 0.0096 = 1.2 ML
Therefore, 1.2 ML will be drawn up
Answer:
115
Step-by-step explanation:
a + s = 345
s = 2a
a + 2a = 345
3a = 345
a = 345/3
a = 115 <===== adult tickets
s = 2a
s = 2(115)
s = 230......student tickets
This is a simple equation that is easily solved.
2x-4=6 You just have to isolate the variable, which is x, to get the solution.
So what you can do, is to get rid of the -4 to isolate the variable by adding 4 to the other side of the equation.
2x-4 (+4)=6+4
2x=10
Then you can isolate the variable by doing the opposite action it says to do, so division.
x=5
