Answer: 2
Step-by-step explanation:
try each value in the equation
2(0) + 1 = 3
0 + 1 = 3
1 ≠ 3
so 0 doesn’t work
2(1) + 1 = 3
2 + 1 = 3
3 = 3
this works, so the answer is 1
They are 6, 8, 10, 12 years old.
all of those added is 36 and two-year intervals translates to 2 years apart per cousin.
Subtract 87 from 700
700 - 87 = 613
You need 613 more points
Answer:
The ratio between them is approximately
, therefore the correct answer is A.
Step-by-step explanation:
In order to calculate the ratio of the diameter of the Sun to the diameter of the Earth we will first represent the Earth's diameter as a scientific notation, to do this we will add one to the power of ten for every time the comma walks to the left until there's only one number to the left. This is done to make the division easier,

The ratio is given by the Sun's diameter divided by the Earth's, as shown below:

The ratio between them is approximately
, therefore the correct answer is A.
L = 3 + w
2(L+w) < 52. Substitute the first equation into inequality
2(3 + w +w) < 52
2(3+2w) < 52 Divide both sides by 2
3 + 2w < 26
2w < 26-3
2w < 23
w < 23/2
w < 11.5
Recall, L = 3+w.
w < 11.5 Add 3 to both sides.
w+3 < 11.5 +3
L < 14.5.
The width is less than 11.5, and the length is less than 14.5.
