If she has 32 miles to the gallon, and 20 dollars, then 5*32 gives you your final answer, which is 160.
Answer:
B: 4/5x -2y ≥ 3
Step-by-step explanation:
The first thing I always look for is the y-intercept which in this case is around -1.5 (-
). That will be your constant (b) in y = mx + b. Then calculate the slope which will be your m in the equation. Visually, I would estimate it is around 
. So now, your equation is y = x -1 
. Next we want to figure out what the inequality will be. The shaded part is underneath the line, which means that y must be less than where the line is. Therefore the inequality will be y ≤ x -1 .
Now in this question, the answers available are not in this form. The next step would be to multiply every part of the inequality by 2 (it is essential that all parts are multiplied) so that you get 2y ≤ 
x -3. The last step is to rearrange the inequality so that it matches the answers on the question.
3 ≤ x - 2y
x - 2y ≥ 3
Answer:
x=9
Step-by-step explanation:
x+18=2x+9
-x -x
18=x+9
-9 -9
9=x
x=9
The exact number is 8,784 toffees but if you want me to estimate to the nearest tens then it would be 8,780
Answer:
116*
Step-by-step explanation:
36* + 28* = 64*
180* - 64* = 116*
