Because 35 is divisible by 7, but 23-21=2, so it becomes 25, which 7 is not a factor of. therefore, it is not divisible by 7.
Answer:
You can follow these steps to multiply a fraction by a whole number:
Write the whole number as a fraction with a denominator of 1.
Multiply the numerators.
Multiply the denominators.
Simplify, if needed. If your answer is greater than 1, you may want to write your answer as a mixed number.

Answer:
A. 11•(8 + 7)
B. 8•(11)-7•(11)
C. 11•(7) + 11•(8)
Step-by-step explanation:
The commutative property of multiplication lets you swap the order of the factors in the product:
(8 +7)•11 = 11•(8 +7)
The distributive property lets you eliminate parentheses:
(8 +7)•11 = 8•11 +7•11
And the commutative properties of addition and multiplication let you rearrange this sum of products to ...
(8 +7)•11 = 11•7 +11•8
Answer:
The value of x + y is -16.
Step-by-step explanation:
If each term is calculated by multiplying the previous one times 5 and then subtracting 20 from that result, then we can use that information to relate the first term (x) and the second one (0).
Following the info above, the following equation applies:
0 = 5 x - 20
then we solve for x:
5x = 20
x = 20/5
x = 4
Now we do the same study relating the second term (0) and the third one (y):
y = 5 (0) - 20
y = -20
Now that we have the value for both unknowns, we can estimate what they ask you: The value of x + y:
x + y = 4 + (-20) = 4 - 20 = -16
Answer:
Step-by-step explanation:
If we add the 2 least numbers it should be greater than the maximum length of the triangle.
Therefore the answer a is satisfied.
