Answer: add 0.3 to both sides
Step-by-step explanation:
1) combine like terms
ALWAYS eliminate constant (number with no variable) Before variable
2) when eliminating constant use the opposite sign, ex: x-5, use +5 to eliminate -5
3) eliminate variable by dividing on both sides
Hope this helps!
Answer:
Option 4.

Step-by-step explanation:
By graphing these we see that these triangles are Similar which means that there corresponding angles measure is equal i-e all angles are equal and hence option 4 is the answer
The answer is 480 because you need to multiply the months by the cost 40(12) which is 480.
Answer:
4 hours, $60
Step-by-step explanation:
Assuming "d" is equal to the dollars Jacob earned and h= hours, you start by setting the equations equal to each other, since both are equal to "d."
15h=10h+20
Subtract 10h from both sides (to combine like terms) so the equation becomes:
5h=20
Divide 5 from both sides, to isolate "d" :
h=4
The number of hours Jacob worked is 4, as the equation above shows. To find the amount of money Jacob made, substitute 4 as "h" into the two original equations:
d= 15(4) d=$60
d=10(4)+20 d=$60
Jacob earned $60 dollars in 4 hours.
