With the regrouping strategy, we get,
50 x 10; 7 x 10; 50 x 8; 7 x 8
Option B is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
57 x 18
This can be written as,
(50 + 7) x (10 + 8)
Simplifying we get,
(50 x 10) + (50 x 8) + (7 x 10) + (7 x 8)
Now,
With the regrouping strategy, we get,
(50 x 10)
(50 x 8)
(7 x 10)
(7 x 8)
Thus,
With the regrouping strategy, we get,
50 x 10; 7 x 10; 50 x 8; 7 x 8
Option B is the correct answer.

You have to solve for x and y!
Answer:
x=−175 and y=−1220
Step-by-step explanation:
Based on the Vertical Angles Theorem, -7x+5=y
Since we know that 2 angles that form a line when combined equal 180 degrees, we know that (4-12x)+y=180
-7x+5=y
(4-12x)+y=180
Now we solve the system:
7x+5=y;−8x+y=180
First, we solve 7x+5=y for y:
7x+5+(−y)=y+(−y)
7x−y+5=0
7x−y+5+ (−5)=0+ (−5)
7x−y=−5
7x−y+(−7x)=−5+(−7x)
−y=−7x−5
-y/-1=(-7x-5)/-1
y=7x+5
Now we will substitute 7x+5 for y in the other equation:
−8x+y=180
−8x+7x+5=180
−x+5=180
−x+5+(−5)=180+(−5)
−x=175
-x/-1 = 175/-1
x=−175
Finally, we'll substitute -175 for x in y=7x+5:
y=7x+5
y=(7)(−175)+5
y=−1220

Solve the system of equations x+y=-1 and 5x-7y=79 by combining the equations.
9514 1404 393
Answer:
(x, y) = (-6, -7)
Step-by-step explanation:
Multiply the first equation by 7 and add that to the second.
7(x +y) +(5x -7y) = 7(-1) +(79)
12x = 72
x = 6
y = -1 -x = -1 -6 = -7
The solution is (x, y) = (6, -7).

find the mean for the scores : 3810;5300;8540;4300,5340
Answer: 5458
Step-by-step explanation: So the mean is the same thing as the average. To find the mean you add up all of the numbers, and then divide by 5 because there are five numbers. So the sum would be 27,290. Then that divided by 5 would be 5458.
The mean of the scores 3810, 5300, 8540, 4300 and 5340 is, 5466.
What is mean?Mean is an average of values of a set. Arithmetic mean, geometric mean and harmonic mean are the type of mean.
The given scores are
3810, 5300, 8540, 4300, 5340
Total number of terms is 5.
To find the mean, use formula,
Mean = sum of terms/number of terms.
Mean = (3810+5300+8540+4300+5340)/5
= 27330/5
= 5466
Mean of the given score is, 5466.

a bank teller. helps two customers omar makes a $15 withdrawal so he balance changes by -$15. jakes makes a $10 deposit so his balance changesby $10
Answer:
D. Omar's transaction involves more money, because |-15| is greater than |10|.
Step-by-step explanation:
The absolute value of a number is simply the magnitude or numerical value of a number while ignoring any sign attached to it. For example, given that x is a real number, absolute value of x, |x| = x. The absolute value of x does not take account of any sign attached to it.
Thus:
The absolute value of Omar's transaction is given as |-15| = 15.
While that of Jake is |10| = 10.
15 is greater than 10.
Therefore, we can conclude that:
"Omar's transaction involves more money, because |-15| is greater than |10|."

Over three days I earn 2568. On the first day I made twice as much as the second day. On the third day I made three times as much as the second day. How much did I earn on the first day.
Answer:
I earned $856 on the first day
Step-by-step explanation:
Let's call
x = earning on the second day
2x = earnings on the first day
3x = earnings on the third day
The total earnings are $2568, thus
x + 2x + 3x = 2568
Simplifying:
6x = 2568
Dividing by 6:
x = 2568/6
x = 428
I earned $428 on the second day.
2x = 2*$428 = $856
I earned $856 on the first day
