Answer:
They have three sides.
Step-by-step explanation:
This is a problem for 2 equations and 2 unknown.
so let x be the number of adults in the breakfast
y be the number of children present in the breakfast
so the total people attended is 500, in equation form
x + y = 500
and the total sales made by disney is $ 7355, in equation
17.95x + 12.95y = 7355
so we can solve the equation simultaneously so solve for the values of x and y
so the number of adults at the breakfast x = 176 adults and y = 324 children
Answer:
97
Step-by-step explanation:
81 + 93 + 76 + 78 + 97 = 425
425/5 = 85
Answer:
Step-by-step explanation:
Four fifths is equal to ten sixteenths of a number. ... Two thirds equals negative eight times a number. ... Three and two thirds times a number equals two ninths.
Evaluate the expression using x = –1 and y=3.
1. Substitute the values for the variables.
we plug in -1 for x and 3 for y
2. Identify grouping symbols, beginning with the innermost symbols.
We take exponent and then we multiply
3. Determine and apply the rules of exponents to simplify
(-1)^4 = -1 * -1 * -1 * -1 = 1
(3)^3 = 3*3*3= 27
4. Evaluate.
162
The value of the expression is 162
