Answer:
x=2
Step-by-step explanation:
3(7-2x)-19-5(4-x) = 3(8-6x)-9x+5(4-x)
or, 21-6x-19-20+5x = 24-18x-9x+20-5x
or, 21-19-20-6x+5x = 24+20-18x-9x-5x
or, -18-x = 44-32x
or, -x+32x = 44+18
or, 31x = 62
or, x = 62/31
or, x = 2
Answer:
Step-by-step explanation:
21-6x-19-20+5x=24-18x-9x+20-5x distribution property
-x-18=44-32x common factors
31x-18=44 add 32x to both sides
31x=62 add 18 to both sides
x=2 divide 31 to both sides(equals 2) so x equals 2

Majed wants to earn at least $30 trimming trees. He charges $7 per hour and pays $5 in equipment fees. What are the possible numbers of hours Majed could trim trees?
Use t for the number of hours.
Write your answer as an inequality solved for t.
Answer:
Step-by-step explanation:
So basically what you want to do is set up an inequality to where 30 is on one side and the variable and the payment is on the other side. The payment is taking away from the profit, so you subtract it. It should look something like this:
30≥7t-5
Now we shall solve for t. Get all like terms to one side:
35≥7t
And divide
5≥t
At least 5 hours to make 30 dollars
PLEASE ANSWER ASAP!!!
line g has and undefined slope. If line k contains the point (-6,3) and is parallel to line g, what are the x-coordinates of the other points that lie on the line?
Answer:
-6 is the x-coordinate value
Step-by-step explanation:
Mathematically, slope can be calculated as;
m = (y2-y1)/(x2-x1)
For the value of the slope to be undefined, it means that we are actually dividing by zero
For us to be dividing by zero, it actually means that there is no change in the x-value
The unchanging x-value is what has caused us to have an undefined slope value
Since line k and line g are parallel, their slopes are equal and the slope of k is undefined too
So the x-coordinates of the other points that lie on the line that we used in calculating the slope is -6

If you want to buy an item in a store that costs $32.50 and is on sale for 30% off, then how much would the item actually cost you after the discount? Round to the nearest cent.
Answer:
$22.75
Step-by-step explanation:
if you multiply $32.50 * 30% you get $9.75
32.50-9.75=$22.75
Answer:
$22.75
Step-by-step explanation:
Convert percent to decimal:
30%=30/100=0.3
Percent formula:
a(1-r)
a(1−r)
32.5(1-0.3)
32.5(1−0.3)
32.5(0.7)
32.5(0.7)

When Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75. When Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120. Find the hourly rate of pay for Ben and Judy.
Answer:
They each earn 15 an hour
Step-by-step explanation:
Answer:
They both make $15
Step-by-step explanation:
In the first scenario Judy worked for 4 hours, (4)*(15)=60 plus Ben, (1)*(15)=15 which equals 75. In the second scenario, Judy works 2 hours so (2)*(15)=30 and Ben works 6, (6)*(15)= 90 which is 120.

2.a. 2.75kg
2.b. 0.19kg
Answer:
2.a. The price of 2.75 kg of pears is $4.62
2.b. The price of 0.19 kg of Pears is $ 0.3192
Step-by-step explanation:
The given parameters are;
The price of each kilogram of Pears = $1.68
Therefore, we have;
The price of a given mass of Pears = The mass in Kg of the Pears × The price per kg of Pears
2.a. The price of 2.75 kg of pears = The mass × The price per Kg = $1.68/kg × 2.75 kg = $4.62
The price of 2.75 kg of pears = $4.62
2.b. The price of 0.19 kg of Pears = The mass × The price per Kg = $1.68/kg × 0.19 kg = $ 0.3192

Gabriel cycles 1,200 meters in 6 minutes. What is his speed?
£800 is divided between Natasha, Richard & Stephen so that Natasha gets twice as much as Richard, and Richard gets three times as much as Stephen. How much does Richard get?
Answer:
Richard gets £240
Step-by-step explanation:
Let
Stephen's share = x
Richards share = 3x
Natasha's share = 2(3x)
Total money = £800
Total money = Stephen's share + Richards share + Natasha's share
800 = x + 3x + 2(3x)
800 = 4x + 6x
800 = 10x
Divide both sides by 10
x = 800 / 10
= 80
x = £80
Stephen's share = x = £80
Richards share = 3x
= 3(80)
= £240
Natasha's share = 2(3x)
= 2(240)
= £480
Richard gets £240
