The answer to your equation: 2/7 x 42 = 12
12 is the correct answer
These rates are not in proportion. Juan walked faster.
Explanation:
First, we want to make these ratios to have the same denominator so we can compare the numerators. To do this, do 3x5 and 8x5 to get 40:15. Then, we do 5x3 and 14x3 to get 42:15. Now we can just compare the numbers 40 and 42, and since 42 < 40, we know Juan walked faster.
<h3>Answer:</h3>
y = 28
<h3>Explanation:</h3>
The base angles of the isosceles triangle are congruent, so the sum of angles is ...
34° + 34° + 4y° = 180°
... 4y = 180 -68 . . . . . divide by °, subtract 68
... y = 112/4 = 28 . . . . divide by the coefficient of y
The value for y is 28.
_____
You have not asked about x in either figure.
<em>First figure</em>
Since the angles are congruent, the sides are congruent. Then ...
... 6x -3 = 5x
... x = 3 . . . . . . add 3-5x
<em>Second figure</em>
The base angles of the isosceles triangle are congruent, so
... 34° = (x -5)°
... 34+5 = x = 39 . . . . . . . divide by °, add 5.
Of course, the number is 7.
You have its square and its cube.
To find x from its square: √49 = 7
To find x from its cube: cubic root of 343 = 7
You made a mistake in the first column. The cubic root of 8000 is 20. The square of 20 is 400
Answer:
3 x $10.50 = $31.50
Step-by-step explanation:
$10.50 + $10.50 + $10.50 = $31.50
$10.00 + $10.00 + $10.00 = $30.00
$0.50 + $0.50 + $0.50 = $1.50
$30.00 + $1.50 = $31.50
