Answer:
Number of pineapples = 10
Number of pears = 10 + 9 = 19
Number of kiwis = 10 - 2 = 8
Step-by-step explanation:
Money = $ 13.5
Cost of a pear = $ 0.5
Cost of a pineapple = $ 1.5
Cost of a kiwi = $ 0.3
let the number of pineapple = p
Number of pears = p + 9
Number of kiwis = p - 2
Cost is
0.5 (p + 9) + 0.15 p + 0.3 (p - 2) = 13.5
0.5 p + 4.5 + 0.15 p + 0.3 p - 0.6 = 13.5
0.95 p = 9.6
p = 10
So, number of pineapples = 10
Number of pears = 10 + 9 = 19
Number of kiwis = 10 - 2 = 8
Answer:
60°
Step-by-step explanation:
If angles are complementary, they add up to 90 degrees. Let x be the complement of the given angle then...
∠A+x=90
30+x=90
Subtract 30 from both sides
x=60
60°
<span>
u need two equations.</span><span>x + y = 125
0.60x + 0.30y = (0.36)(125)</span>
<span /><span>x + y = 125
0.60x + 0.30y = 45</span>
<span>solve for a variable in the first equation
y = 125 - x</span>
<span>plug into the second equation
0.60x + 0.30(125 - x) = 45
0.60x + 37.5 - 0.30x= 45
0.30x + 37.5 = 45
0.30x = 7.5
x = 25</span>
<span>plug the answer for x into the first equation
25 + y = 125
y = 100</span>
