Answer:
1. Yes; 2. Yes ; 3. No; 4. Yes
Step-by-step explanation:
The proportion will have to be read the same way. For example top Δ bottom to the lower Δ bottom (locate in the same place)
14/21 = 6 /9 Yes because the top Δ bottom to lower Δ bottom = top side to
lower same side
13.5/21 = 9/ 14 Yes because the same two sides to the same two sides in
the lower Δ
9/13.5 = 6 21 No because top Δ side to lower Δ same location but the
second one top Δ side to the lower bottom
14 /6 = 21/6 Yes because top Δ bottom to top side = lower Δ bottom to
lower side (in the same place)

Answer is B
To find (f+g)(x), add the equations and simplify by combining like terms.
(x/2)-2+2x^2+x-3
2x^2+ (x/2) +x -5
2x^2 + (1/2)x+x -5
2x^2+ (3/2)x -5
Final answer: C
Remember that (x/2) is the same as (1/2)x. They both represent half of x.
75.99 (tenths)
75.991 (hundredths)
75.9913 (thousandths)
There are many different paths to take but here is my take
15%:22.5%:48%: 74 3/4 Turn everything into a percent
15%:22.5%:48%: 7475% Turn into a decimal
.15: .22: .48: 74.75 Times by 100
15: 22 : 48: 7475 Covert into factors
5(3) : 2(11) : 3(2⁴): 5²(299) Relize there is no common factor...
15: 22 : 48: 7475 <------- Whole numbers
