Yes, J can be determined if H=54. The interior angles of a triangle always add up to 180. Since we know H=54 and J and I are equal.
J+I+H=180
J+I+54=180
J+I= 126
Because J&I are equal you can just divide 126 by 2
J=126/2
J= 63
Answer:
53/20 but simplified its 2 13/20
Step-by-step explanation:
Answer:
z-3/z+3-z-9/z2+3z
Final result :
3 • (z3 + z2 - z - 3)
———————————
z2
Step-by-step explanation:
Step 1 :
9
Simplify ——
z2
Equation at the end of step 1 :
3 9
((((z-—)+3)-z)-——)+3z
z z2
Step 2 :
3
Simplify —
z
Equation at the end of step 2 :
3 9
((((z - —) + 3) - z) - ——) + 3z
z z2
Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using z as the denominator :
z z • z
z = — = ——
1 z
Peter answered 9 of the questions correctly. 15 divided by 100 to get .15 and then multiply by 60 to get 9. Got 9 correct, 7 incorrect.
ANSWER: 8/21
Step:
1. Find the GCF (Greatest Common Factor)
The two denominator which is the bottom number have to be the same ALWAYS when adding and subtracting the fraction. So to find the GCF, you keep multiplying until you see the same number, only use the bottom number to find the GCF
7: 7, 14, 21, 28
3: 3, 6, 9, 12, 15, 18, 21, 24, 27
GCF= 21
2. 5/7 -1/3
Multiple both to get 21
5/7 x 3/3 = 15/21
1/3 x 7/7 = 7/21
3. Sove
15/21 - 7/21
= 8/21
