a = 56
given 28 = 
a
multiply both sides by 2 to eliminate the fraction
56 = a
As a check
× 56 = 28 ← True
How I’d do it:
5/6 three times makes 15/6. Made into a mixed fraction is 2 3/6, which in its simplest form is 2 1/2.
When converted to ounces, assuming that 6/6 is one complete ounce, then you get 2.5 ounces.
The total weight she picked up is 2.5 ounces.
15. [4] insufficient information. only given SA
16. There are 3 right triangles, 3 Pythagorean theorem equations
x²+b²= 16²
12²+a² = x²
a²+4² = b²
combine equations using substitution to get in terms of only x
substitute b² for (a² +x²) in first equation
x²+a²+4²=16²
substitute a² for (x² - 12²)
x²+x²-12²+4² = 16²
solve for x
2x² - 144 + 16 = 256
2x² = 256 + 144 - 16
2x² = 384
x² = 384/2
x² = 192
x = 13.85
rounded to nearest tenth, x = 13.9
It's C, just look at where the points are.
Answer:
Step-by-step explanation:
Equation:1
Equation:2
Solving Equation:1
Subtracting 'y' from both the sides:
Putting 'x' in Equation :2
Adding '4' both the sides
Putting the value of 'y' in equation:1
The solution is:
