Answer:

=10t-6-7.5t = 6-0.5t

= 2.5t- 6 = 6-0.5t

= 2.5t+0.5t = 6+6

= 3t = 12

= t = 12/3

t = 4

Therefore the answer is 4

1. the equation is y=mx+b. m= slope and b= y-intercept so your answer should be y=2/3x+2

2. point-slope form is y-y1/x-x1=m answer is y+4=-1(x-1)

3. i give up im sorry my brain is fried ;-;

A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 3

Cloud [144]

Answer:

x=7, so the smaller number is 7 and the larger number is 21.

Step-by-step explanation:

x=3x+5=33

Let x=3:

(3)+3(3)+5=3+9+5=17, not 33, so x is not 3

Let x=5:

(5)+3(5)+5=5+15+5=25, not 33, so x is not 5

Let x=7:

(7)+3(7)+5=7+21+5=33, so x=7

Let x=9:

(9)+3(9)+5=9+27+5=41, not 33, so x is not 9

Therefore x=7. Because x represents the smaller number, and the larger number is 3 times the smaller number, the smaller number is 7 and the larger number is 3(7)=21.
