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
Answer:
c.) Congruent
Step-by-step explanation:
If two angles are vertical they are also congruent.When two lines intersect to make an X, angles on opposite sides of the X are called vertical angles. These angles are equal, and here's the official theorem that tells you so. Vertical angles are congruent: If two angles are vertical angles, then they're congruent. (Hope This Helps)
Answer:
x= 5 1/3
Step-by-step explanation:
l3x-5l=11
3x-5=11
+5 +5
3x=16
/3 /3
x=5 1/3
Answer:
Charlene claim is true.
Step-by-step explanation:
Max claims that a point on any line that is perpendicular to a segment is equidistant from a segment's endpoints.
It is not necessary as shown in the diagram (a).
Charlene claims that the line must be a perpendicular bisector for a point on the line to be equidistant from a segment's endpoints.
It is true as shown in the diagram (b).
So, Charlene claim is true.
120×90/100 = 12×9 = 108
