Answer:
33.33%
Step-by-step explanation:
78x = 52
52/78 = x
0.6667 = x
to get this as a percentage, multiply 0.6667 by 100 to get 66.67%
this is the discounted percentage but to get the discount percent, you subtract 100 by this percentage to get 33.33% off
The equation is
y = -(6/7)*x + 9
We just need to evaluate the function in x = 21
This means
y = -6*21/7 +9 = -6*3 +9 = -18 +9 = -9
(x,y) = (21,-9)
Answer:
12, 6 and 30
Step-by-step explanation:
Step one:
given data
Number of medals = 48 medals
The given ratio is = 2:1:5
The total ratio is = 2+1+5= 8
Step two;
Applying the part to all method
for Gold we have
2/8=x//48
cross multiply
8x= 48*2
divide both sides by 8
x= 96/8
x= 12
gold is 12
for silver we have
1/8=x//48
cross multiply
8x= 48*1
divide both sides by 8
x= 48/8
x= 6
silver is 6
for bronze we have
5/8=x/48
cross multiply
8x= 48*5
divide both sides by 8
x= 240/8
x= 30
Bronze is 30
The answer is 9.48. also I rounded
Answer:
$30.
Step-by-step explanation:
70/28 = 2.5
12 x 2.5 = 30
