A bouncy castle can be hired for party's. The cost is given by Cost=£4.70 times number of children + £86. What is the cost of the bouncy castle for 13 children. At a different party, the cost of hiring the bouncy castle was £165.90.How many children went to the party.
Answer:
A. £147.10
B. 17 children
Step-by-step explanation:
Let
Number of children = x
Cost of hiring a bouncy castle = £4.70 * x + £86
What is the cost of the bouncy castle for 13 children
Cost of hiring a bouncy castle = £4.70 * 13 + £86
= £61.1 + £86
= £147.10
How many children went to the party when cost of hiring bouncy castle = £165.90
Cost of hiring a bouncy castle = £4.70 * x + £86
£165.90 = £4.70 * x + £86
165.90 = 4.70x + 86
165.90 - 86 = 4.70x
79.9 = 4.70x
x = 79.9/4.70
= 17
x = 17 children

Step-by-step explanation:
Figure A has a perimeter of 24 inches. Figure B has a perimeter of 36 inches and one of its side lengths is 12 inches. Find the missing corresponding side length.
Answer:
The corresponding side length is 8 inches
Step-by-step explanation:
Similar Shapes
Two shapes are similar if all of their side lengths are in the same proportion. For example, triangle 1 has sides of 3-4-5 and another similar triangle has sides of 15-20-25. Note all their lengths are proportional with a scale factor of 5.
We are given the perimeter of figure A Pa=24 inches and the perimeter of figure B Pb=36 inches. The scale factor can be obtained as 36/24=3/2.
If one of the lengths of figure B is 12 inches, then the corresponding length for figure A is 12/(3/2) = 8 in.
The corresponding side length is 8 inches

What should be subtracted from -8xy + 2x^2 + 3y^2 to get x^2 + 2
Answer:
x^2 - 8xy + 3y^2 - 2
Step-by-step explanation:
(-8xy + 2x^2 + 3y^2) - unknown = x^2 + 2
- unknown = x^2 + 2 + 8xy - 2x^2 - 3y^2
- unknown = -x^2 + 8xy - 3y^2 + 2
Unknown = x^2 - 8xy + 3y^2 - 2
Check:
(-8xy + 2x^2 + 3y^2) - (x^2 - 8xy + 3y^2 - 2)
= -8xy + 2x^2 + 3y^2 - x^2 + 8xy - 3y^2 + 2
= -8xy + 8xy + 2x^2 - x^2 + 3y^2 - 3y^2 + 2
= x^2 + 2
