The value of y can be calculated by translating the equation such that we solve y in terms of x.
-3x - 8y = 10
-8y = 10 + 3x
y = (10 + 3x) / -8
Then, we substitute 2 to the x in the equation.
y = (10 + 3(2)) / - 8 = 16/-8
y = -2
Thus, the value of y in the equation is -2.

Answer:
Step-by-step explanation:
Let x represent the amount of medical bills that Giselle has to pay.
Assume she has over $160 in bills,
it means that
x > 160
Under plan A, Giselle would have to pay the first $110 of her medical bills, plus 35% of the rest. Therefore, she will have to pay for
35/100 × (x - 110) = 0.35(x - 110)
Under plan B, Giselle would pay the first $160, but only 20% of the rest. Therefore, she will have to pay for
20/100 × (x - 160) = 0.2(x - 160)
Therefore, the amount of medical bills that plan B will save is
0.35(x - 110) - 0.2(x - 160) = 0.35x - 38.5 - 0.2x + 32
0.15x + 6.5
Substituting x = 160 into 0.15x + 6.5, it becomes
0.15 × 160 + 6.5 = $30.5
Total bills would be 160 + 30.5 = 190.5
Therefore, Giselle would save $30.5 with plan B if she had more than $190.5 in bills.
Answer:
2.4
Step-by-step explanation:
Okay so first what you would do is find the common difference we can find this by doing 5/3 which is 1.66666666667 (rounded to 1.7)
Then what we do is 4 divided by 1.66666666667 which is 2.4
Step-by-step explanation:
6-15x-6-10x
put the like terms together and it's now -15x-10x+6-6
-25+6-6
=-25
