Answer:
<em>7, 22</em>
Step-by-step explanation:
Let S = the smaller number.
"The larger number is 1 more than 3 times the smaller number."
The larger number is 3S + 1.
The difference between the numbers is 15, so the larger number minus the smaller number equals 15.
3S + 1 - S = 15
2S + 1 = 15
2S = 14
S = 7
The smaller number is 7.
larger number = 3S + 1 = 3(7) + 1 = 21 + 1 = 22
The larger number is 22.
Answer: the 4th boy is 11
Step-by-step explanation:
Let's denote the age of the boys as: x₁, x₂, x₃, x₄.
Then,
Multiply both parts of the equation by denoting by 3:
x₁+x₂+x₃=15(3)
x₁+x₂+x₃=45
Hence,
Multiply both parts of the equation by denoting by 4:
45+x₄=14(4)
45+x₄=56
45+x₄-45=56-45
x₄=11
Answer:
From what it looks like AC and CB are equal so first,
6^2 x 6^2 = AB
then,
6 x 6 = 36
36 x 36 = 1296
Finally, find the square root of that number.
the answer should be 6cm... WOW, that was so confusing but it should be 6cm.
Answer:
So A, D, and G.
Step-by-step explanation:
When x = 2, both expressions have a value of 18. True
The expressions are only equivalent for x = 4 and x = 6. False
The expressions are only equivalent when evaluated with even values. False
The expressions have equivalent values for any value of x. True
The expressions should have been evaluated with one odd value and one even value. false
When x = 0, the first expression has a value of 4 and the second expression has a value of 5. False
The expressions have equivalent values if x = 8. True
