239.99 x 75%(75/100) ~ $180
$180 x 90%(90/100) = $162
Sally wants to buy some groceries. She wants to buy 2 kg of potatoes and 1 kg of onions. 1 kg of onions cost $5 but the paper that shows price of potatoes got lost. However, Sally remembers that few weeks ago she bought 3 kg of potatoes for $12. How much did Sally spent buying groceries?
Part 1:
First we need to find how much 1 kg of potatoes cost.
3*x = 12
x = 4
1 kg of potatoes cost $4
Part 2:
Now we need to find how much did she spent.
M = 4*2 + 1*5 = $13.
Answer:
(a-2b)/4
Step-by-step explanation:
log 9 (sqrt(f)/g) = 0.5*log 9 (f(x)) - log 9 (g(x))= 0.5*0.5*log 3 f(x) - 0.5*log 3 g(x) = a/4 - b/2=(a-2b)/4
Answer:
Step-by-step explanation:
area of top=7×6=42 yd²
area of bottom=3×6=18 yd²
area of two rectangles=2[4×6]=48 yd²
area of two trapezoids=2[1/2(7+3)×3.5]=35 yd²
total surface area=42+18+48+35=143 yd²
Answer:
Step-by-step explanation:
The slope-intercept formula is:
y= keep as variable
m= slope of the line
x= keep as variable
b= y-intercept of the line.
