Answer:
36
Step-by-step explanation:
The answer is easy to find if we use the cross-multiplication method.
We know 7 students out of 10 picked apples, then 3 out of 10 picked bananas.
We know the number of people who picked apples.

We just have to isolate x, this way and solve the problem:

becomes

So, 36 students picked bananas as their favorite fruit.
Answer:
X=7
Step-by-step explanation:
4x-(2x-9)=23 simplified would be
4x-2x+9=23
2x+9=23
2x=14
X=7
Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
Answer:
33 1/3% decrease
Step-by-step explanation:
The original area is (6in)(10in) = 60 in². The reduced area is (5in)(8in) = 40 in². Then the change in area is ...
((new value)/(old value) -1) × 100%
(40/60 -1)×100% = -1/3×100% = -33 1/3%
The area decreased by 33 1/3%.
Answer:
$12320
Step-by-step explanation:
Given data
Cost of car= $17500
rate of depreciation= 11%
duration= 2003 - 2006= 3 years
Let us apply the compound interest formula
A= P(1-r)^t
Note the negative sign(this is because of the depreciation)
A=17500(1-0.11)^3
A= 17500(0.89)^3
A= 17500*0.704
A= $12320
Hence the value of the car is $12320
