Answer:
1. 98.8 2. 194 3. 49 2/3
Step-by-step explanation:
I found the pattern of each of them
Here is the math I did for the 1st one: 1.3(1st number)+2.5*39(pattern times one less than the term number you want)=98.8
This is actually the first time I have done this, so I this should help both of us!!! Me with learning more math, and you with doing your own math.
Your question has been heard loud and clear.
let the ratio be m:n
From section formula
(-3n + 4m)/(m+n) = 2
-3n + 4m = 2m+2n
5n = 2m
m/n = 5/2
m:n = 5:2
Answer:
60%
Step-by-step explanation:
Answer:
2x= 40°
5x= 100°
Step-by-step explanation:
2x on opposite angle because it is an isosceles triangle
2x+ 2x+ 5x = 180° (angles of a triangle)
9x= 180
x= 180/9
x= 20°
Sub
2(20)= 40°
5(20)= 100°
Answer:
The cost for 1 chair is $2.75 and the cost for 1 table is $8.75
Step-by-step explanation:
Use the elimination method of linear equations to find your answer.
Our equations for this problem are:
3c+5t=52 and 9c+7t=86
1. Multiply the entire first equation by -3.
-3(3c+5t=52)
2. Simplify the equation from above:
-9c-15t=-156
3. Stack the two equations on top of each other and add/subtract:
-9c-15t=-156
9c+7t=86
4. You should be left with -8t=-70. Simplify this to find the value of t:
t=8.75
5. Plug the value of t into any of the original equations and solve for c.
3c+5(8.75)=52
6. Simplify the equation above:
3c+43.75=52
7. Subtract 43.75 from both sides of the equation:
3c=8.25
8. Divide both sides by 3 to get your c value:
c=2.75
