Answer:
(a) = 7 +3·5
Step-by-step explanation:
The given expression evaluates to ...
6 +2^4 = 6 +16 = 22
The offered choices evaluate to ...
7 +3·5 = 7 +15 = 22
4·10^3 +96 = 4·1000 +96 = 4096
7^2 = 49
3·10 +2 = 30 +2 = 32
The only choice that will form a proper equation is the expression that evaluates to 22:
6 +2^4 = 7 +3·5

Answer: 24 for red, 40 for blue and 64 for white.
Step-by-step explanation:
To get the shade of purple paint ordered by a client, the colours mixed are red, blue and white in the ratio 3:5:8.
Red= 3
Blue= 5
White= 8
Total = 3+5+8 = 16
Since 128fluid make a gallon, the number of fluids ounces for each colour will be:
Red = 3/16 × 128
= 24
Blue= 5/16 × 128
= 40
White = 8/16 × 128
= 64
The fluid ounces of colours needed are 24 for red, 40 for blue and 64 for white.
Answer:
y=7 and x=-8
Step-by-step explanation:
Isolate x in the first equation:
10x=-17-9y
x=(-17-9y)/10
Substitute into the second equation:
7*((-17-9y)/`10)+10y=14
-119/10+37y/10=14
-119+37y=140
37y=259
y=7
Putting this into the first equation, we get that x=-8
