Answer:
12m + 36 or 6 (2m + 6 )
Step-by-step explanation:
12( 3 + m )
Apply distributive property...
(12 · 3) + (12 · m)
36 + 12m
Get it in order...
12m + 36
Another possibility...
Take 6 out of both numbers:
(12m ÷ 6) + (36 ÷ 6)
6 ( 2m + 6)
When you multiply 6 by 2m and 6 by 6, you'll get 12m + 36
Answer:
850 bagels in 10 hours.
Step-by-step explanation:
340 divided by 4 is 85. 85 times 10 is 850. So, 850 bagels.
M = 24
To solve that you divide 42/7 which is 6 then you multiply 4*6 and you get 24
Step-by-step explanation:
a. we simply subtract 3. from 2.
x + 2y + z = 15
- -3x + y + z = 2
--------------------------
4x + y 0 = 13
b. we multiply 3. by 3 and then subtract from 1.
2x - 4y + 3z = -7
- -9x + 3y + 3z = 6
-----------------------------
11x - 7y 0 = -13
c. we multiply the result of a. by 7, and then simply add a. and b., because the y terms have different signs already.
28x + 7y = 91
+ 11x - 7y = -13
--------------------------
39x 0 = 78
39x = 78
x = 2
d. we use this x = 2 in the result of a.
4×2 + y = 13
8 + y = 13
y = 5
e. using x = 2 and y = 5 in 2.
2 + 2×5 + z = 15
2 + 10 + z = 15
12 + z = 15
z = 3
the solution is therefore (2, 5, 3).
