Answer:
120 - (W*7)= A
Step-by-step explanation:
Let's say after 3 weeks. $120 is what he owes her in the beginning. He pays her $7/week.
After 3 weeks, he owes her 120 - (W*7)= A.
W=3, since we are 3 weeks along. So, after 3 weeks he still owes her
120 - (3*7)= A >>> 120 - 21= A >>> 99= A.
Step-by-step explanation:
24 + 28
2*2*2*3 + 2*2*7 [prime factors]
You may distribute any common ones, for example:
4(6+7) [that is, 2*2*(2*3 + 7)
2(12+14)
Answer:
-18

Answer:
The graph is shown below.
Step-by-step explanation:
Given:
Equation of a line is ![y+1=-\frac{3}{5}(x-4)](https://tex.z-dn.net/?f=y%2B1%3D-%5Cfrac%7B3%7D%7B5%7D%28x-4%29)
The equation of a line with a point
and slope
is given as:
![y-y_{1}=m(x-x_{1})](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%29)
On comparing the given equation with the standard form, we get
![x_{1}=4,y_{1}=-1,m=-\frac{3}{5}](https://tex.z-dn.net/?f=x_%7B1%7D%3D4%2Cy_%7B1%7D%3D-1%2Cm%3D-%5Cfrac%7B3%7D%7B5%7D)
Now, we first plot the point
.
Slope is
. This means that we have to move 3 units down and 5 units right to get the slope as negative. We mark the second point there.
Now, we plot a line joining both the points. Thus, the graph is drawn.
You have to count up all the tallys. There are 50 tallys altogether. So for a, 2 is rolled 9 times. so 9/50. for b, 23 odd roles, so 23/50
