Answer:
Emily's mother will donate $20
Step-by-step explanation:
0.5x20=10
Answer:
No solution.
Step-by-step explanation:
That image is of the symbol of the empty set. The solution set is empty, which means there is no solution.
A = oz of the solution A
b = oz of the solution B
The scientist knows that solution A is 45% salt and solution B is 95% salt. She wants to obtain 80 ounces of a mixture that is 65% salt.
a + b = 80
0.45a + 0.95b = 0.65*80
by solving the above system of equations you'll find····
a = 48 oz
b = 32 oz
~I hope this helped~
If it doesn't make since, I can try to switch up the wording ^^
Answer:
y = 2/5x - 3
P (0,5)
parallel lines have equal slopes
slope intercept form of an equation
y = mx + b
m = slope, b = y-intercept
parallel to y = 2/5x - 3,
and through P(0, 5)
m = 2/5
y intercept = 5
so, the equation would be
D. y = 2/5x + 5
