Answer:
16
Step-by-step explanation:
Answer:28,30,32
Step-by-step explanation:
The sum of three consecutive even integers is 90. Find the Integers.
N= first even number we need to find
N+2= second even number
N+4= third even number
90= is the sum of all 3 even integers
N+n+2+n+4=90
Add all n together
3n+2+4=90
Add 2 plus 4
3n+6=90
Subtract 6 bith sides
3n=90-6
Subtract 90 from 6
3n= 84
Divide 3 both sides
3n/3=84/3
Divide 84 by 3 to solve for n
N= 28
So furst even number is 28. Now to find second and third number substitute 28 into the bext two equations .
N+2=? For second numb.
28+2=30 second number
N+4=? For third number
28+4=32 for third number
To check add all 3 answers
28+30+32=90
58+32=90
90=90 it checks
So three even numbers are 28,30,32
Answer:
7. 32
8. 68
9. 16
10. 29
Step-by-step explanation:
7. =90°-58
=32
8. =68°
9. = (1 + 5x)°
= (1 + 5(16)°
=81
10. = (2x + 3)°
= (2(29) + 3)°
= 61°
Answer: 16 feet is the width and 25 is length
Step-by-step explanation:
x*(2x-7)=400
Word problem written in numerical form^^^^
Solve for x to get 16
length = 2(16)-7= 25
Check our work
16*25=400 yay
