Kendra hasn’t missed a day of school in 245 days. This is twenty days less than five times the number of days it has been since Brandon has missed a day of school. How many days has it been since Brandon missed a day of school?

Answers

The equation would be 5x+20=245
X=the number of days Brandon missed.
Subtract 20 from both sides; 5x=225
Then divide by 5; x=45
It has been 45 days since Brandon missed school.

Answer:

The answer is 53

245 = 5y - 20 | y = 53

Step-by-step explanation:

subtracting 20 ( - 20) represents "twenty days less"

5y represents "five times the number of days"

This is all being compared to Kendra's 245 days of perfect attendance which is why it's "245 ="

Plug it in! & don't forget PEMDAS ----> 5(53) - 20 = 245

If grade point average rises as number of hours watching tv falls, the correlation between GPA and TV is

Answers

If the grade point average (GPA) rises as the number of hours spent watching TV falls, the correlation between GPA and TV is likely negative or inversely correlated. This means that as one variable (TV watching) decreases, the other variable (GPA) tends to increase. Negative correlation is represented by a negative correlation coefficient, typically ranging from -1 (perfect negative correlation) to 0 (no correlation). In this case, the correlation coefficient would be less than 0 but greater than -1.

If you pay $8.50 per square yard of carpeting, what is your total cost for 27.5 square yards?a. $233.75
b. $223.75
c. $228.75
d. $232.75

Answers

Answer:

a.$233.75

Step-by-step explanation:

We are given that

Cost of 1 square yard of carpeting =$8.50

We have to find the total cost for 27.5 square yards.

Using unitary method

Cost of 27.5 square yards of carpeting =27.5* 8.50

After multiplying , we get

The cost for 27.5 square yards of carpeting =$233.75

Hence, the cost for 27.5 square yards of carpeting=$233.75

Answer:a.$233.75
the answer is A because if you pay $8.50 per square yard it means multiply. Per is the key word and then you just multiply $8.50 and 27.5 to get A

Monica’s school band held a car wash to raise money for a trip to a parade in New York City. After washing 125 cars, they made $775 from a combination of $5.00 quick washes and $8.00 premium washes. Let x represent the number of quick washes and let y represent the number of premium washes. Which system of linear equations represents the situation? 5x + 8y = 775 and x + y =125 5x – 8y = 125 and x + y = 775 5x + 8y = 775 and x – y = 125 5x – 8y = 125 and x – y = 775
