Answer:
Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.
Explanation:
Marks received by Marta in four tests = 86, 84, 97 and 89
Let mark received in fifth test be x
We have average of five test is more than or equal to 90
So we have
So Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.
Answer:
2 cups
Step-by-step explanation:
if she uses 1/2 cup of oil per 1 cup of peanut butter
then she should use the ratio PB(peanut butter)= 2O(oil)
so if oil is 1 then PB must be 2 cups
Answer:
Option C is correct
Step-by-step explanation:
We need to factorize the expression:
For factorization we need to break the middle term such that the product is equal to 24x^2 and the sum is equal to 10x
We know that 6*4 = 24 and 6+4 =10
So, solving
Taking common
So, the factors of
are
Hence Option C is correct
Website 1 : y = 1.50x + 30
website 2 : y = 2x + 0...or just y = 2x
=======================
y = 4x - 4
y = -4x + 4
4x - 4 = -4x + 4
4x + 4x = 4 + 4
8x = 8
x = 1
y = 4x - 4
y = 4(1) - 4
y = 4 - 4
y = 0
so this is a consistent system because it has one solution (1,0)
If you would like to find the x-intercept of the line with the equation 4x + 2y = 12, you can do this using the following steps:
4x + 2y = 12
y = 0
4x + 2 * 0 = 12
4x = 12
x = 12/4 = 3
(x, y) = (3, 0)
The correct result would be <span>d. (3, 0).</span>
