Answer:
$6.07/hr. if I understand the question properly. See below.
Step-by-step explanation:
I don't see the question, but will assume we want to find Larisa's base pay. The $7/hr given is the average for the work sequence noted in the problem. If this is incorrect, ignore the answer.
==================================
Let x be Larisa's base salary. We are told, I think, that in one stretch of time Larisa earned an average of $7/hour. That was composed of:
<u>Hours</u> <u>Rate($/hr)</u>
40 x
3 1.5x
<u> 6 </u> 2x
49
Her total income over this period would be:
40x +3(1.5x) + 6(2x) [The hours worked times the pay rate for each period]
Her average income per hour would be:
(40x +3(1.5x) + 6(2x))/49
which we are told is $7/hr.
(40x +3(1.5x) + 6(2x))/49 = 7
40x + 4.5x + 12x = 343
56.5x = 343
x = $6.07/hr
Answer:
x = -11
Step-by-step explanation:
Considering tripled means multiplied by 3 because of tri, we know that we can use the equation 3x = -33.
To solve this we can divide both sides by 3:
3x = -33
x = -11
This gives our answer of -11.
Answer:
Step-by-step explanation:
In a pen there are 200 animals,
25 of which are ducks,
Number of turkeys
50% are turkeys
= 50% × 200
= 100 turkeys
and
Numbers of chickens
75% are chickens.
= 75% × 200
= 150
How many animals are ducks, turkeys and chickens?
Answer:
y = -2x + 12
Step-by-step explanation:
Parallel = Same Slope Perpendicular = Opposite Reciprocal of Slope
How to find "b" or y intercept:
y = mx + b (3,6) slope = m: -2
plug in the corresponding values for the variables
6 = -2(3) + b
12 = b
