Answer:
68
Step-by-step explanation:
- We have to find area first:
Flower bed: (triangle)
A =
1/2 × 3 × 8
3 times 8 is 24, time 1/2 is <u>12</u>
Vegetable Patch: (trapezoid)
A =
5 + 7 = 12
12 / 2 = 6
6h or 6 × 10 = <u>60</u>
Whole Garden:
14 × 10 = 140
2. Then we subtract.
140 - 72 is 68
Let
x = number of tulips
y = amount of daffodils
We have the following system of equations:
x + y = 15
5x + 2y = 45
Solving the system
Step 1:
-5x + -5y = -75
5x + 2y = 45
Step 2:
-3y = -30
y = 30/3 = 10
Step 3:
x = 15-y
x = 15-10
x = 5
Answer:
she should use
10 daffodils
5 tulips
Answer:
x^2 - 8x + 64 remainder 217 or you could write it as
(x^2 - 8x + 64)+ 217/(x + 8)
Step-by-step explanation:
You first need to write the polynomial in descending order of degree with zero coefficients for x^2 and x terms, so here we have:
x^3 + 729 = x^3 + 0x^2 + 0x + 729
So dividing by x+8:-
x^2 - 8x + 64 <----------the quotient.
x + 8 ) x^3 + 0x^2 + 0x + 729
x^3 + 8x^2
- 8x^2 + 0x
-8x^2 - 64x
64x + 729
64x + 512
217 = Remainder.
Answer:
Step-by-step explanation:
For what mileages will company A (which has a flat rate of $111) be less than the cost for company B
Company A < Company B
111 < 75 + 0.80m
solving
111 - 75 < 75 - 75 + 0.80m
36 < 0.80m
36/0.80 < 0.80m/0.80
as we are dividing by a positive number, we don't have to change the direction of the < sign.
45 < m
or m > 45
so if Ali intends to drive more than 45 miles, Company A's vehicle will be less expensive to rent
