Answer:
88 score.
Step-by-step explanation:
Given:
To get a B in math, Alexandria Pappas must<u> average 80</u> on five tests.
Scores on the first four tests were <em>82, 74, 82, and 74.</em>
Question asked:
What is the lowest score that she can get on the last test and still get a B?
Solution:
Let lowest score she can get on the last test =
As we know:
By cross multiplication:-
Thus, she can get 88 score on the last test to get a B in math.
Answer:
The equation of the line is,
Step-by-step explanation:
First, you have to write it in a form of y = mx + b :
When both lines are parallel to each other, they will have to same gradient value. So the equation of the line is y = (-2/5)x + b. Next, you have to find the value of b by substutituting (-10,3) into the equation :
Answer:
Step-by-step explanation:
To calculate a+1/a, we first need to calculate for a.
a = 7 - 4 *
square root of 3 = 1.73
a = 7 - 4 * 1.73
a = 7 - 6.9
a = 0.1
0.1 + 1 / 0.1 = 0.1 + 10 = 10.1
Now, in case 4 wasn't being multiplied with the square root of 3, and instead, it was four root of 3, I am gonna do the calculations again:
a = 7 -
a = 7 - 1.31
a = 5.69
5.69 + 1 / 5.69 = 5.69 + 0.17 = 5.86
Hope I Helped!
