Let x represent the number of hours that he spent washing cars.
Let y represent the number of hours that he spent landscaping.
In a week, he can work no more than 19 total hours. This means that
x + y ≤ 19- - - - - - - - - - - -1
Jacob is working two summer jobs, making $10 per hour washing cars and making $8 per hour landscaping. He must earn at least $170. This means that
10x + 8y ≥ 170 - - - - - - - - - -2
If Jacob worked 4 hours landscaping, it means that
x + 4 ≤ 19 x ≤ 19 - 4 x ≤ 15
Also, 10x + 8 × 4 ≥ 170 10x + 32 ≥ 170
10x ≥ 170 - 32 10x ≥ 138
10x ≥ 138/10 x ≥ 13.8
The minimum number of hours is 14

My last math question of the day! Help me out!
What equation can be used to find B, the number of points scored!
Thank you!
Answer:
A
Step-by-step explanation:
Let b represent the number of points Ben scored.
We know that Lori scored 26 points.
This amount is two less than four times what Ben scored.
Four times what Ben scored will simply be 4b.
And two less will be 4b - 2.
This is equivalent to Lori's score.
So, we can write that:
[tex]4b-2=26[/tex]
Hence, our answer is A.
Answer:
I believe it is A
Step-by-step explanation:
Since in this problem you would want to find b, which is stated the is almost 4 times 26... however is 2 less. The other options are wrong since you would want a bigger number, not a smaller one... Hopefully this is helpful

Answer:
hope you like my question
Step-by-step explanation:
Hi -
What you want to do here is solve the equation by substitution.
To do that, you solve one of the equations for y. then plug that into the other equation so you have an equation with only x as the variable.
1) Solve either equation for y. Lets go with the first one:
4x+5y=102
Subtract 4x from each side:
5y=102-4x
Divide both sides by 5
y=(102-4x)/5
2) Plug this value for y into the other equation we started with:
7x+5y = 126
7x + 5((102-4x)/5) = 126
3) Solve the resulting equation for x.
Since we are multiplying and dividing (102-4x) by 5 the 2 5s cancel each other out
7x + 5((102-4x)/5) = 126
7x + 102 - 4x = 126
Combine the 2 x terms:
3x+102=126
subtract 102 from each side:
3x = 24
Divide both sides by 3:
x=8
Once we have a value for x, we can plug that number into either one of our starting equations to solve for y.
4x + 5y = 102; if x = 8
32+5y = 102
subtract 32 from each side:
5y = 70
Divide both sides by 5:
y = 14
So x = 8 and y = 14.
You can check your work by plugging these numbers both into your 2 initial equations.
4x+5y=102; 4*8+5*14 = 102
7x+5y=126; 7*8 +5*14 = 126

Which equation is equivalent to
Answer:
4K^4
Step-by-step explanation:
Answer:
4k^4
Step-by-step explanation:
Just break it down step by step. The cube root of 64 is 4, since 4*4*4 = 64.
The cube root of k^12 is k^4, since k^4*k^4*k^4 = k^12 (since you add the exponent together when multiplying.
So, when you put this together, the cube root must be 4k^4.

Step-by-step explanation:
the angle of a triangle in the ratio 1:3:5 how much is the larger angle
Answer:
100°
Step-by-step explanation:
The sum of all the angles in a triangle is 180°.
This is 1 + 3 + 5 = 9
180 ÷ 9 = 20
The scale factor is 20.
Multiply 5 (the greatest angle) by the scale factor.
5 x 20 = 100

Classify each polynomial according to its degree and type. Look at the screenshot below!
find the nth term of the following sequence
-7 ,-4 , -1 , 2 ,5
Answer:
3n - 10
Step-by-step explanation:
Find the difference between the terms
-7 , -4 , -1, 2, 5
+3 +3 +3 +3
Difference of terms = 3, so you'd write that as 3n
Then you'd need to find the difference between the 1st term and 3:
3 > -7
- 10
So you'd write that as 3n - 10

The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm? 3.14 d less-than 50 3.14 d greater-than 50 50 d greater-than 3.14 50 d less-than 3.14
Answer:
3.14 d greater-than 50
(i also need help with one of my questions >~<)
Step-by-step explanation:
Since the circumference of a circle is approximately 3.14 times the length of its diameter, mathematically speaking:
C = 3.14d
That expression must be greater (>) than 50:
3.14 d > 50
So, the correct option is; 3.14 d greater-than 50

Victor drew a square with vertices at (1,2), (3,2), (3,4), and (1,4). He slides the square 5 units up to create an image. What are the vertices of the image? (1,7), (3,7), (3,9), and (1,9) (6,2), (8,2), (8,4), and (6,4) (1,-2), (3,-2), (3, -4), and (1,-4) (1,-3), (3,-3), (3, -1), and ( 1,-1)
Answer:abcd
Step-by-step explanation:
"If a point (x, y) is shifted 'h' units upwards, coordinates of the image point will be",
(x, y) → (x, y + h)
If the vertices of a square are,
A(1, 2), B(3, 2), C(3, 4), D(1, 4)
If these vertices are shifted 5 units upwards, then the coordinates of the vertices of the image will be,
A(1, 2) → A'(1, 2+5)
→ A'(1, 7)
B(3, 2) → B'(3, 2+5)
→ B'(3, 7)
C(3, 4) → C'(3, 4+5)
→ C'(3, 9)
D(1, 4) → D'(1, 4+5)
→ D'(1, 9)
Therefore, Option (A) will be the answer.
