Since the angles at the centre subtended by the congruent arcs WX and YZ
Then ∠YOZ = ∠WOX = 103° → C
Answer:
344 visitors
Step-by-step explanation:
Given that the relationship between the number of visitors to a museum(y) and the daily rainfall in mm(x) is defined as
y=14.1x+62.0
when the daily rainfall is 20 mm, the number of visitors
y = 14.1(20) + 62
= 282 + 62
= 344
It means that the expected number of visitors is 344 persons (to the nearest integer).
3(8x - 5) = -4(7 - 6x)
Distribute 3 and -4 inside their respective parentheses.
24x - 15 = -28 + 24x
Add 28 to both sides.
24x + 13 = 24x
Subtract 24x from both sides.
13 = 0
This is an untrue statement, so that means there are no solutions to this equation.
Your answer is no solution.
Answer:
Step-by-step explanation:
Let Freda's sum = x
Donnie has 3/4 x
He spends 63 dollars. His sum is now
3/4x - 63
Now the equation looks like this
6(3/4x - 63) = x Remove the brackets
6*3/4 x - 378 =x
6 * 3/4 = 4 1/2
4 1/2 x - 378 = x Add 378 to both sides
4 1/2 x = x + 378 Subtract x from both sides
3.5 x = 378 Divide by 3.5
x = 378 /3.5
x = 108
Since x = 108, that's how much Freda had. (She spent nothing).
