Develop two linear equations to represent the savings of these two people:
Raul: rl=$350 + $15x
Ruth: rh=$200 + $25x
In both cases, x represents the number of weeks elapsed.
When will these two people have saved up the same amount? Set rl = rh and solve for x, the number of weeks elapsed:
$350 + $15x = $200 + $25x
$150 = $10x gives us x= 15. Their savings will be equal after 15 weeks.
Answer:
the answer is e
Step-by-step explanation:
96 (high score) - 67 (low score) = 29 (range)
16.75% mark up.
To find this, minus the difference....
23,000 - 19,700 = 3,300..
then divide by the first cost...
23,000 ÷ 3,300 = 0.1675
now multiply that by 100...
0.1675 x 100 = 16.75%
Answer: 11
Step-by-step explanation:The given expression is:
=
=
=
Substituting the value of b=-2 in above expression, we get
=
=
=
Thus, the value of the given expression is -11.
All of the side lenghts of the smaller triangles have been multiplied by 2 which guarantees side side side similarities. (basically similar angles shows congruence when their sides are proportional)
