Answer:
Total number of tables of first type = 23.
Total number of tables of second type = 7
Step-by-step explanation:
It is given that there are 30 tables in total and there are two types of tables.
Let's call the two seat tables, the first type as x and the second type as y.
∴ x + y = 30 ......(1)
Also a total number of 81 people are seated. Therefore, 2x number of people would be seated on the the first type and 5y on the second type. Hence the equation becomes:
2x + 5y = 81 .....(2)
To solve (1) & (2) Multiply (1) by 2 and subtract, we get:
y = 7
Substituting y = 7 in (1), we get x = 23.
∴ The number of tables of first kind = 23
The number of tables of second kind = 7
If max starts with 5 apples and then gives away too hes subtracting 2 so he has 3 left
equation: 5-2=3
Answer:
The answer is B.
Step-by-step explanation:
answer: y = 1.5x - 5.5
explanation:
use y = mx +b to model your equation
(m = slope, b = y-intercept)
let's start by finding slope
to find slope, subtract the y values over the x values.
- 4 - (-1) / - 5 - (-3)
solve and simplify.
-3 / -2
two negatives equals a positive, so convert into a decimal and remove the negative
you get 1.5.
now, plug the slope a y and x value into the equation to find b, the missing value.
-1 = 1.5(3) + b
-1 = 4.5 + b
-5.5= b
so, your equation is y = 1.5x - 5.5.
(8c)^2+7c
(8c)^2=64c^2
so that..
64c^2+7c
factor out c
c(64c+7)
