Answer:
105 sweets
Step-by-step explanation:
There are 4 + 1 + 2 = 7 parts in total
Stephen gets 4 parts (or 4x)
Jim gets gets 2 parts (or 2x)
Given,
Stephen gets 30 more than Jim, we can write:
Stephen = Jim + 30
or
4x = 2x + 30
We can solve for "x":
There are 7 parts of sweets altogether (or 7x), we know x so:
There are:
7 * 15 = <u>105 sweets</u> altogether

Answer:
z = 8
Step-by-step explanation:
PythagoreanTheorem
a^2 + b^2 = c^2
a and b stand for the legs while c stands for the hypotenuse. Since we have the numeral for one of the legs and the hypothenuse, we can plug those into the formula.
a^2 + 15^2 = 17^2
a^2 = 64
a = 8
