Answer:
$30,000 and $55,000
Step-by-step explanation:
If 4.5% loan is x, and the 6% loan is y, then:
x + y = 85000
0.045x + 0.06y = 4650
Solve the system of equations with substitution or elimination. Using substitution:
0.045x + 0.06(85000 − x) = 4650
0.045x + 5100 − 0.06x = 4650
450 = 0.015x
x = 30000
y = 55000
First of all calm down and brake down the problem plan a is $25 a month while the other one is $40 you need to subtract to get $15 than divide $15 by $0.25 which you will get 60 but this is not the right answer because its asking you how many phone calls is the cost of plan b less than the cost of plan a so the answer is 59 calls.
Answer:
Step-by-step explanation:
# angle ABC is congruent to angle DEF which’s given
# angle GHI is congruent to DEF which’s given
#angle DEF is congruent to DEF / symmetric property
# angle ABC is congruent to GHI / transitive property
(ABC+DEF=DEF+GHI)
- SUBTRACT DEF from both sides
ABC=GHI
Answer :
(x–30) (x-10)
Given equation :
• x² - 40x + A
when A = 300
1. Use the sum-product pattern
x²- 40x + 300
x²−10x−30x+300
2. Common factor from the two pairs
x² – 10x-30x+300
x(x−10)−30(x−10)
3. Rewrite in factored form
x(x−10)−30(x−10)
(x-30) (x-10)
