Answer:
20
Step-by-step explanation:
Perimeter of equilateral triangle = 3a
a represents side
60 = 3(3x+2)
60 = 9x + 6
9x = 54
x = 6
Length of one side = 3×6 + 2= 18+2 =20
Answer:
The answer is Option 2.
Step-by-step explanation:
I just took the quiz.
Total muffins and doughnuts = 18
Assumed all doughnuts = 18 x $0.4 = $7.20
But she paid $9.15.
$9.15 - $7.20 = $1.95
$1.95 must have been used to pay for the muffin.
Difference in price between muffin and doughnuts:
$0.55 - $0.40 = $0.15
Number of muffins bought = $1.95 ÷ 0.15 = 13
She bough 13 muffins.
Number of doughnut bought = 18 - 13 = 5
She bought 5 doughnuts
Answer: She bought 5 doughnuts and 13 muffins.
Answer:
y = -6x + 4
Step-by-step explanation:
=> y = -6x + 4
according to the image drawn the line appears to have landed on the y-axis on the number four and the x-axis on the number -6 so we have to make y the subject of formula
=. y = -6x + 4
The answer is B just did that question
