Write the inequality and solution.
justin wants to have at least a 75 test average in algebra 1 this six weeks. he will have 3 test grades. he received a 72 and a 76 on the first two tests. what must he make on the third test to receive at least a 75 test average? inequality is required for full credit.

77

Step-by-step explanation:

add the sums and divide by 3

reverse: 75*3=225

225-72-76=77

you can't solve x because it is 2 linear equation and you only have one equation

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
