-1.....if the number on the left is smaller than the number on the right change the the number on the right to equal the same on the left then however many numbers down you went make that a negative and that’s your answer
Let's translate each sentence into "Math".
Pineapple = p
Orange = x
is means equal
Pineapple is 7 times as heavy as an orange: p = 7x
Pineapple weighs 870 grams more than orange. p = 870 + x
Substitute p = 7x into the second equation:
7x = 870 + x
Subtract x from both sides
6x = 870
divide by 6
x = 145
The orange weighs 145 grams.
The pineapple weights 7 times the orange = 7(145) = 1015 grams.
Answer:
The diameter of a circle is twice the radius
since the radius of Russell's circle is 6cm
the diameter will be twice 6cm
that is 12cm
maintaining the ratio
radius to diameter
6cm : 12cm
1:2
Thanks
Answer:
Step-by-step explanation:
Solution,
Given ratio=2:3
Boys & girls=15:45=15/45=1/3=1:3
Since, 2:3≠1:30. Hence given rations are not in proportion
