Answer:
x = -8/3
y = 5
Step-by-step explanation:
Finding the equation of the line:
y = 3x +c
Substituting (-2,5) into 'y=3x+c':
5 = -6 + c
c = 11
Hence,
y = 3x + 11
For finding x:
Substituting (x, 3) into 'y = 3x +11':
3 = 3x + 11
3x = -8
x = -8/3
For finding y:
Substituting (-2, y) into 'y = 3x + 11':
y = -6 + 11
y = 5

Esteban is 11 years older than Mya. Last year Esteban was twice as old as Mya. How old is Mya now?
Answer:
Mya is 12
Step-by-step explanation:
EEstaban is 11 years older so Estaban was 22 and Mya was 11
so now Maya is 12
Hope this helps! :)
Answer: 12 years old
Step-by-step explanation:
Let x be Esteban's age, and let y be Mya's age.
x = y + 11
x-1 = 2(y-1)
Substitute
y + 11 - 1 = 2 (y - 1)
Solve
y + 10 = 2y - 2
12 = y

Mother bought 3 cans of sardines at ₱17.80 each, 5 cans of milk at ₱38.85 each, 3kg sugar at ₱60.50 each, and 2 cans of corn beef at ₱78.85 each. Find the total amount bought. If she paid ₱500 bill, find her change.
Step-by-step explanation:
Total amount is:
3*17.80 + 5*38.85 + 3*60.50 + 2*78.85 = 586.85If the numbers are correct ₱500 won't be enough as the total amount exceeds it.
Mother bought 3 cans of sardines at ₱17.80 each, 5 cans of milk at ₱38.85 each, 3kg sugar at ₱60.50 each, and 2 cans of corn beef at ₱78.85 each. Find the total amount bought. If she paid ₱500 bill, find her change.
Statement:Mother bought 3 cans of sardines at ₱17.80 each, 5 cans of milk at ₱38.85 each, 3kg sugar at ₱60.50 each, and 2 cans of corn beef at ₱78.85 each.
Solution:The total amount for which she had brought the items
= ₱ (3×17.80 + 5×38.85 + 3×60.50 + 2×78.85)
= ₱ (53.40 + 194.25 + 181.50 + 157.70)
= ₱ 586.85
Answer:The total amount for which she had brought the items is ₱ 586.85.
I cannot solve the second part of the sum because the amount exceeds ₱ 500.

Which of the following represents the equation of a line that is parallel to 2y-x=16 and passes through the
point (-6, 1)?
The equation of a line that is parallel to (2y - x = 16) and passes through the point (-6, 1) is [tex](y - 1)=0.5(x+6)[/tex] and this can be determined by using the slope-intercept form of the line.
Given :
Line Equation -- 2y - x = 16Point -- (-6,1)First, convert the given line in slope-intercept form that is in the form of (y = mx + c).
2y = x + 16
[tex]y = \dfrac{1}{2}x +16[/tex]
Comparing the above equation with slope-intercept form.
m = 0.5
c = 16
The line parallel to the line (y = 0.5x + 16) means the slope of that line is also equal to 0.5.
The equation of the line whose slope is m and passing through the point [tex](x_1,y_1)[/tex] is given by:
[tex](y-y_1) = m(x-x_1)[/tex]
Now, put the value of slope m and point [tex](x_1,y_1)[/tex] in the above equation.
[tex](y - 1)=0.5(x+6)[/tex]
So, the equation of a line that is parallel to (2y - x = 16) and passes through the point (-6, 1) is [tex](y - 1)=0.5(x+6)[/tex].

3.6w=2(0.8w+12)
Use the Distributive Property:
3.6w=1.6w+24
Move all the constants to the left side:
3.6w-1.6w=24
2w=24
Divide both sides by 1.8 to isolate w:
w=12

Answer:
W=12
Step-by-step explanation:
3.6w=2(0.8w+12)
3.6w=1.6w+24
Subtract 1.6w from both sides
3.6w-1.6w=1.6w+24-1.6w
Simplify
2w=24
Divide both sides by 2
2w/2=24/2

Anna Page, a teacher, earns $1.320 semimonthly. If the school's insurance plan costs a total of

paychecks?
Do Hors senderized Meta RecticeMelvin divers, a traveling salesman, has company medical
this
insurance as well as travel insurance. The company he works for pays 60 percent of the
medical insurance and 90 percent of the travel insurance. If the medical insurance has an
annual cost of $3,500 and the travel insurance costs $1,200 per year, what total amount is
deducted from his weekly paycheck for insurance?
A. $2923 B.-561.15 G365 D. 59.04
(a) The amount that is deducted from each of Page's paychecks semimonthly is $717.
(b) The amount deducted per week is option A, $29.23.
(a) Given that:
The amount earned by Page semimonthly = $1320
Total cost for the insurance plan = $2868
The school pays 75 per cent of the cost.
The percentage of the insurance cost that Page has to pay = 100% - 75% = 25%.
The amount deducted from the paycheck of Page is:
A = 25% × $2868
= $717
(b) Given that:
The annual cost of medical insurance = $3500
The percentage of this insurance he has to pay = 100% - 60% = 40%.
Annual deduction from his paycheck = 40% × 3500
= $1400
The annual cost of travel insurance = $1200
The percentage of this insurance he has to pay = 100% - 90% = 10%.
Annual deduction from his paycheck = 10% × 1200
= $120
Total amount deducted per year = $1400 + $120
= $1520
Number of weeks in a year = 52 weeks
The amount deducted per week = [tex]\frac{1520}{52}[/tex]
= [tex]$29.23[/tex]
Hence, the correct option is A. $29.23.

x + y = 7
3x - 2y = 11
By using Substituting method.
[tex]\large\underline{\sf{Solution-}}[/tex]
[tex]\sf \longmapsto x + y = 7 \: \: - - - (i)[/tex]
[tex]\sf \longmapsto 3x - 2y = 11 \: \: - - - (ii)[/tex]
By first equation,
[tex]\sf \longmapsto x + y = 7[/tex]
[tex]\sf \longmapsto x = 7 - y[/tex]
Now, we can find the original value of y.
[tex]\sf \longmapsto 3x - 2y = 11[/tex]
[tex]\sf \longmapsto 3(7 - y) - 2y = 11[/tex]
[tex]\sf \longmapsto 21 - 3y - 2y = 11[/tex]
[tex]\sf \longmapsto 21 - 5y = 11[/tex]
[tex]\sf \longmapsto - 5y = 11 - 21[/tex]
[tex]\sf \longmapsto - 5y = - 10[/tex]
[tex]\sf \longmapsto y = \dfrac{ - 10}{ - 5} [/tex]
[tex]\sf \longmapsto y = 2[/tex]
Now, we can find the original value of x.
[tex]\sf \longmapsto x + y = 7[/tex]
[tex]\sf \longmapsto x + 2 = 7[/tex]
[tex]\sf \longmapsto x = 7 - 2[/tex]
[tex]\sf \longmapsto x = 5[/tex]
Therefore, the values of x and y are 5 and 2 respectively.
