GCF(56; 64) = 8
56 = 8 · 7
64 = 8 · 8
56 + 64 = 8 · 7 + 8 · 8 = 8·(7 + 8)
Used distributive property: a(b + c) = ab + ac
1. The car is 10km/h faster than the bus
Explanation:
50/2.5=20
50/5=10
20-10=10
2. m=-1.5
Explanation
5+7=12
-5-3=-8
12/-8=-1.5
3. f(-4)=-22
Explanation:
f(-4)=4(-4)-6
4. x=37
Explanation
44=2x-30
74=2x
x=37
n, n + 2, n + 4 - three consecutive odd ntegers
n + (n + 2) + (n + 4) = 5(n + 2) - 18 |use distributive property
n + n + 2 + n + 4 = (5)(n) + (5)(2) - 18
3n + 6 = 5n + 10 - 18
3n + 6 = 5n - 8 |subtract 6 from both sides
3n = 5n - 14 |subtract 5n from both sides
-2n = -14 |divide both sides by (-2)
n = 7
n + 2 = 7 + 2 = 9
n + 4 = 7 + 4 = 11
Answer: 7, 9, 11.
Answer:

Step-by-step explanation:
reasearchers know hot to read and write
Answer:
Step-by-step explanation:
Here's a completely valid trick for finding the equation of this new line:
Start with the given 2x + 4y = 6. Replace that '6' with 'C.' We need to find C. To do this, replace x with 6 and y with 4 and calculate C:
2(6) + 4(4) = C, or 12 + 16 = C. Thus, C = 28, and the desired equation is
2x + 4y = 28, or (in simplified form) x + 2y = 14
