Answer:
b = -2
Step-by-step explanation:
Given expression:
9(b - 4) - 7b = 5(3b -2)
Using distributive properties, open the parentheses;
9b - 36 - 7b = 15b - 10
2b - 36 = 15b -10
collect like terms;
2b - 15b = - 10 + 36
-13b = 26
Divide both sides by -13;
b = -2
You need to make two equations-
Use b for butternut squash and z for zucchini.
2b+4z = $6.96
3b=6z
Solve for one of the variables in the second equation ( I will solve for b)
3b/3=6z/3
b=2z
Plug it in-
2(2z)+4z =$6.96
4z+4z=$6.96
8z =$6.96
8z/8 = 6.96/8
z= .87
Plug in again - (b=2z)
b= (2)(.87)
b= $1. 74
So the zucchini is 87 cents and the butternut squash is $1.74 (each)
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
