Question

Write an algebra1. The length of a rectangle is 3 more than twice its width. The perimeter is 48 feet.
2. Fifteen more than four times a number is 6 more than five times the number. Use "n" for the number.
3. Martha and Sally had lunch together on Tuesday. Sally paid $2 more than Martha. The total bill was $5.64.
4. Bob paid $3 less than Tim at a local pizza parlor. Together they spent $7.80.
5. There were six more women on a committee than men. The committee was made up of 30 people.
6. Three consecutive integers have the sum of 153.

Answer 1

i just need 1 and 6

Answer 2

1. Length is 3 more than twice the width. Call lethth 'L' and width "w" then 'twice the width' is 2w and three more than that is +3 so: L=2w+3

Answer 3

Permeter is 48 and P = 2L + 2w. so 2L+2W=48. From there you can substitute one into the other and solve.

Answer 4

6. 'Three conssecutive numbers' --> n, n+1, n+2 so
n+(n+1)+(n+2)=153
3n+3=153
3n=150
n= 150/3
n=50

Answer 5

Five times the first of three consecutive even integers is fourteen more than three times the second. What is the third integer? @twvogels

Answer 6

(5*n) +14 = 3*(n+2)
5n+14=3n+6
8=-2n
n=-4
Therefore the numbers are -4, -2, and 0, the third one is 0.

Answer 7

To check:
(5*-4)+14 = -6 and 3*(-4+2) =-6
so it checks.

Answer 8
