Answer:
y=-
x+
Step-by-step explanation:
The value for x is 9 because:
7x +49 = 2x + 94
7x-2x=45
5x=45
x=45/5
x=9
In this problem, we are asked to give an expression that can be used to mentally multiply 6 and 198. In order not to go through the rigorous multiplication, we can estimate 198 to 200, that is 6 *200 equal to 1200. Since there is a 2*6 excess or 12 then we subtract: 1200 -12 equal to 1188.
