Let's call job one x.
Job two can be y.
Jason earned $3,700 more from job y than x. Therefore y = x + 3700
From the two jobs, Jason earned $15,900. This can be written as x + y = 15900.
Now substitute y for x + 3700:
x + x + 3700 = 15900
2x + 3700 = 15900
Subtract 3700 from both sides:
2x = 12200
Divide both sides by 2:
x = 6100
Take the original equation x + y = 15900 and substitute x with 6100:
6100 + y = 15900
y = 9800
Job one (x) paid Jason $6,100.
Job two (y) paid Jason $9,800.
Answer:
14
Step-by-step explanation:
Because you do 2.50 times 30 and that is 75. Next you do 110 - 75 and that is equal to 35. Next you divide 35 by 2.50 and you get 14.
Answer:
For this equation to be true, a must = 13 and b must = 10 + 2i.
Step-by-step explanation:
First combine the numerators: 3 + 5 + 2i + 2, or 10 + 2i.
Next, multiply the denominators: 4 + 9 = 13
Then rewrite the original equation as:
10 + 2i a
---------- * ---- = 1
13 b
For this equation to be true, a must = 13 and b must = 10 + 2i.
Answer:
False
Step-by-step explanation:
(4/5) / 8 does not equal 2/5. It would be 1/10.
A graphing calculator shows it will take about 5.5 seconds.
