If X is increased by 7 to make 21
X + 7 = 21
then rearrange the equation to get X
X = 21-7
X = 14(b)
Answer:
-4
Step-by-step explanation:
(4-2)³ = 8
so 8 - 3 x 4
is equal to -4
B I’m not 100% sure but I think
Answer:
32, 46
Step-by-step explanation:
Remember, a is congruent to b modulo d if d divides a-b.
Now, the problem says that b=4 and d=14.
Let a=32. Observe that a-b=28 and
, then 32 is congruent to 4 modulo 14.
Let a=46. Observe that a-b=46-4=42 and
, then 46 is congruent to 4 modulo 14.
Answer:
B: $90.
Step-by-step explanation:
The expression for this problem can be represented as
Total Cost = $44 + 2c
Since one chair costs $23, the total cost would be:
Total Cost = $44 + 2($23)
2 × 23 = 46
Total Cost = $44 + $46 = $90
The total cost is $90, choice B.
