Answer:
Step 3.
Operation error, where the sign on the number changes from -ve to +ve where shifted to the left side of the equation.
Step-by-step explanation:
Given that 2(10 - 13x) + 9x = -34x + 60
<u>Step 1. Distribute</u>
20-26x+9x=-34x+60
<u>Step 2: Combine like Terms</u>
20-17x=-34x+60 -------------------------(-26x+9x = -17x)
<u>Step 3: subtraction property of equality</u>
-17x+34x=60-20--------------------- (60-20 =40)
-17x+34x=40
<u>Step 4 :Addition property of Equality</u>
-17x+34x=40-------------------(-17x+34x =17x)
17x=40
<u>Step 5: Division property of Equality</u>
17x=40
17x/17 = 40/17
x=40/17
Answer
x=40/17
<u>Errors</u>
In step 3
-17x+34x = 17 x and not 51x
In step 5
-51x=40
x=-40/51 (not the other way round, -51/40) however correct operation is supposed to be;
17x=40, hence x =40/17
Draw diagarm
we want to know the hyptohuse
use cos
cos(x)=opositeside/hhyptohuse
hypothuse=length of ramp
cos(18°)=26/?
times both sides by ?
?cos(18°)=26
divide both sides by cos(18°)
?=26/(cos(18°))
use your calculator
?=27.338in
the ramp is about 27in
Originally the ratio is 5:3, but we can make this ration 5x:3x because its equal. By doing so, we know that 5x+3x=32.
Now just solve the equation:
5x+3x=32
8x=32
x=4.
Now insert x into ratio.
Since she needs 3x of guava juice, she needs 3*4 fl oz of guava juice. She need 12 fl oz of guava juice.
Answer:
12 FL OZ of guava juice.
Answer:
Step-by-step explanation:
it is an arithmetic sequence.
c=6-3=3
\[a_{n}=3+(n-1)*3\]
\a_{n}=3n
a_{8}=3*8=24
