Answer:
-3
Step-by-step explanation:
In the slope-intercept form of linear equation (y=mx+b) the slope is the number next to the x, here represented with the letter m. In your equation, y =-3x+7, the m is replaced by -3, so the slope here is -3.
Let x = the amount of grapes that can be bought for 0.40.
Note: By 90 I assume you mean 90 cents. The same for 40.
12/x = 0.90/0.40
0.90x = 12(0.40)
0.90x = 4.80
x = 4.80 ÷ 0.90
x = 5.33333
We can round the decimal to the ones place to get 5 grapes.
The slope for the line is 3/4
Answer:
3/12
Step-by-step explanation:
2/3 of the 3/4
=3/4×2/3
=6/12
=1/2
this is to say a half of the boys are wearing tennis shoes
since the total number of boys in the class is 3/4
1/2 of the 3/4
=3/12
