Answer:
[[274][895][136]]
Step-by-step explanation:
Starting with the middle row, we need a product of two single-digit numbers that is between 53-1 = 52 and 53-9 = 44. Possible products are 5×9=45 and 6×8=48. This means the number in the middle position in the left column must be 8 or 5.
The middle number in the left column cannot be 5, because we must be able to get -5 by subtracting that number from a sum that is at least 3 = 1+2. So, the middle number in the left column is 8, the other two numbers in that column are 1 and 2, and the other two numbers in the middle row are 5 and 9.
There is no product of single-digit numbers that is 30-1 = 29, so the upper left number must be 2, and the bottom left number must be 1. The other two numbers on the top row must be 4 and 7, so that row's equation is 2+4×7=30.
The only remaining digits are 3 and 6. In order to have -3 on the bottom row, the equation there must be 1×3-6 = -3. Then the middle digit must be divisible by 3, so must be 9.
Our solution is ...
row 1: 2 + 7 × 4 = 30
row 2: 8 + 9 × 5 = 53
row 3: 1 × 3 - 6 = -3
And that makes the column equations be ...
col 1: 2 - 8 + 1 = -5
col 2: 7 + 9 / 3 = 10
col 3: 4 × 5 - 6 = 14
Answer: 2 1/4
Step-by-step explanation:
From the question, we are told that a recipe call for 3/4 c of chopped pecans
and that Brentt wants to triple the recipe .
The numerical expression that represents the amount of pecans he will need will be gotten by multiplying 3/4c by 3. This will be:
= 3 × 3/4c
= 9/4c
= 2 1/4
Answer:
The first number lets say is x
the second is y so
y=1/2x+8
x+1/2x+8=58
1 1/2x=50
x= 33 1/3

Answer:
1) D
2) D
Step-by-step explanation:
1. Use 360 - x˚ - y˚ - 117˚ - 62˚
2. Recognize that 1) can be either 62 or 63
3. Plug either number into x to get y
4. y = 118 when x = 63
(12/30)x100 is 40%
This is percent of incorrect answers. The total percent must be 100% so subtract 100-40=60%.
60% answers were answered correctly.
