To solve for x
x+7y=-4
x=-4-7y
Answer:
Area of the garden = 98 + 19.25 = 117.25 ft²
Step-by-step explanation:
Area of the garden = area of the rectangle + area of the semi-circle
Area of the rectangle = L x B = 14 x 7 = 98 ft²
Area of the semi-circle = 1/2 x πR² = 1/2 x 22/7 x 3.5² = 19.25 ft²
Hence area of the garden = 98 + 19.25 = 117.25 ft²
Answer:
Student 2 used the correct steps to construct parallelogram PQRS.
Step-by-step explanation:
Out of all the students, student 2 got all the steps correct.
Fix the compass at Q and draw an arc that intersects side QP.
Without changing the width of the compass, move the compass to R and draw an arc.
Draw a line segment from R that passes through T and intersects the second arc at S.
The all go over 18 so put them all over 18
16/18+12/18+3/18=31/18
31/18 or 1.722222222........
Answer: the school paid $80 for the book.
Step-by-step explanation:
Let x represent the amount that the school paid for the book.
Her school charges a lost book fee equal to 75% of the cost of the book. It means that the amount that the school would charge on a book that cost $x is
75/100 × x = 0.75 × x = 0.75x
Sarah received a notice stating that she owed the school $60 for he lost book. It means that
0.75x = 60
x = 60/0.75
x = $80
