Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $8 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y represent the number of hours Leah works at the ice cream shop. How did you determine the pair(s) (x, y) that Leah could work to meet the given conditions in item 15?
Answer:
Babysitting= 13.3 hours
Icecream shop= 6.6 hours
Step-by-step explanation:
Step one:
let the hours for babysitting be x
and the hours for icecream shop be y
we are told that Leah would like to earn $120 monthly
She babysits for $5 per hour and
works at an ice cream shop for $8 per hour
5x+8y=120---------------1
Leah cannot work more than a total of 20 hours per month
x+y≤20-------------2
The system of equation for the situation is
5x+8y=120
x+y≤20
x=20-y
put x=20-y in eqn 1
5(20-y)+8y=120
100-5y+8y=120
3y=120-100
3y=20
y=20/3
y=6.6 hours
put y=6.6 in eqn 2
x+6.6≤20
x≤20-6.6
x=13.3hours
please answer this. thank you
4x-y= -2
2х + Зу = 13
Answer:
x = 1/2
y = 4
Step-by-step explanation:
4x - y = -2 --------------------(I)
2x + 3y = 13 --------------------(II)
Multiply equation (I) by 3 and then add
(I)*3 12x - 3y = -6
(II) 2x + 3y = 13 {Now add and so y will be eliminated}
14x = 7
x = 7/14
x = 1/2
Plugin x = 1/2 in equation (I)
[tex]4*\frac{1}{2}-y = -2[/tex]
2 - y = -2
-y = -2 - 2
-y = -4
y = 4
Answer:
x=1/2
y=4
Step-by-step explanation:
4x-y=-2
-y=-4x-2
y=4x+2
2x+3y=13
2x+3(4x+2)=13
2x+12x+6=13
14x=7
x=1/2
y=4x+2
y=4(1/2)+2
y=2+2
Y=4
y=x^5 three units right and four units down?

Solve for x. assume that lines which appear to be diameters are actual diameters.
Answer:
x=10
Step-by-step explanation:
5x+17 = 67
The angles are vertical angles which means they are equal. This means the arc lengths are equal
5x+17-17 = 67-17
5x = 50
5x/5 = 50/5
x =10

Laura borrowed $105,000 at a rate of 6% simple interest for 12 years. How much interest will Laura pay?
Group of answer choices
$75,600
$37,800
$180,600
$256,200
Answer:
Laura will pay an interest of $75,600.
Step-by-step explanation:
Our formula: A = P(1 + rt)
Principal = $105,000
Rate = 6%
Time = 12 years
A (amount)= 105,000(1 + (0.06 × 12)) = 180,600
$180,600 - $105,000 = $75,600.

Danielle is making a quilt with triangles and squares. There are 4 colored triangles inside each square. The base and height of each triangle is x + 4 inches as shown. Which polynomial represents the area of the colored triangles in square inches?
Answer:
[tex](2x^2+16x+32)\ \text{sq. inches}[/tex]
Step-by-step explanation:
b = h = Base = Height of triangle = [tex](x+4)\ \text{inches}[/tex]
Area of one triangle
[tex]A=\dfrac{1}{2}bh=\dfrac{1}{2}(x+4)(x+4)[/tex]
There are 4 colored triangles so total area of the triangles is
[tex]4A=4\times \dfrac{1}{2}(x+4)(x+4)\\\Rightarrow 4A=2(x+4)^2\\\Rightarrow 4A=2(x^2+8x+16)\\\Rightarrow 4A=2x^2+16x+32[/tex]
The area of the colored triangles is [tex](2x^2+16x+32)\ \text{sq. inches}[/tex]
A point on the ocean floor is 5,962 m below sea level. Express this elevation as an integer.
the elevation as an integer is ___ m.
Answer:
-5,962 m
Step-by-step explanation:
Since the point is below sea level, it will be a negative number as an integer.
it is 5,962 m below sea level, so as an integer, it will be -5,962 m.
So, the elevation as an integer is -5,962 m

GCF of 2 prime numbers is always 1, because prime number only have two factors, themselves and 1.
LCM of 2 prime numbers will be simply multiplying them together.
Sasha can do that by; finding the HCM of two factors.
Razi will tell Jake to find the LCM you have to find the least common factor of the numbers,and then that's your answer.

Determine the nth term rule and find the 45th term for the arithmetic sequence with a10=1 and d=−6.
Answer:
a(45) =-209
Step-by-step explanation:
a(n) = a +(n-1)d
d=-6
we have to get a1
By using:
a(10) = a1 +(10-1)-6=1
a(10) = a1 +(9)-6 =1
a1 =1+54=55
So:a(45) = 55 +(45-1)-6=-209
hope this helps
