Answer:
Frank has $22.34.
Step-by-step explanation:
24 pennies - 0.01 x 24 = 0.24
62 nickels - 0.05 x 62 = 3.10
55 dimes - 0.10 x 55 = 5.50
16 quarters - 0.25 x 16 = 4.00
19 half dollar (50cent) - 0.50 x 19 = 9.50
0.24 + 3.10 + 5.50 + 4.00 + 9.50 = 22.34
You can add like terms. Like terms are terms that have the same variables and the same exponent.
11x + 5 + -11x + 29 =
= 11x + -11x + 5 + 29
= 34
Answer: 34
22. Step by step: 2x^2+5x-3=0
factor the left side
(2x-1)(x+3)=0
set the factors to equal zero
2x-1=0 and x+3=0
x=1/2 x=-3
23. Use same technique.
3x^2-13x-10=0
factor the left side once more
(3x+2)(x-5)=0
set factors to zero
3x+2=0 and x-5=0
x=-2/3 x=5
