Volume = length x width x height but there are only 2 demiintions
2 x 2 1/2=
first, make 2 1/2 into an improper fraction
2 x 2=4+1=5
5/2 is the improper fraction
now, write 2 as a fraction, 2/1
now, 5/2 x 2/1=5 or 5/1
This is the answer, I don't know it is wrong
Subtract the given score x from the mean µ and divide it by the standard deviation σ :
z = (x - µ) / σ = (302 - 300) / 20 = 0.1
Answer:
x=147
(x-24) = 123
Step-by-step explanation:
x + (x-24)=360
since all paralelograms equal up to 360
simplify 2x - 24 = 260
add 24 on both sides to isolate
2x = 294
divide both sides by 2
x = 147
(x-24) = 123
Answer:
The expression is (80w+300)
Step-by-step explanation:
Let
y ----> the total amount of money in both accounts
s ----> the amount of money in saving account
c ----> the amount of money in checking account
w ----> the number of weeks
we know that
<em>saving account</em>
s=50w+200 -----> equation A
<em>checking account</em>
c=30w+100 ----> equation B
To find out the total amount of money in both accounts, sum equation A and equation B
y=s+c
substitute
y=(50w+200)+(30w+100)
y=(50w+30w)+(200+100)
y=80w+300
therefore
The expression is (80w+300)
