9
Step-by-step explanation:
15x+12=19x-24
15x-19x=-24-12
-4x=-36/÷(-4)
x=9
You first put all the x on one side and numbers on the other and be careful about + and - and then you divide by everything with the x so you have only the x left and you get the aswer.
Answer:
x=9

Find the slope of the line that passes through (7,2) and (3,3)
Answer:
1 over 4
Step-by-step explanation:
Answer:
the answer is [tex]\frac{1}{-4\\}[/tex]
Step-by-step explanation:
slope= [tex]y_{2}[/tex]-[tex]y_{1}[/tex]
[tex]x_{2}[/tex]-[tex]x_{1}[/tex] so 3-2=1 and then 3-7=-4

Sketch the graph of y+2=1/2(x-3)
Answer:
Step-by-step explanation:
y= 1/2x + −7/2
how do solve slope and for the y axis?
Answer:
Slope = rise/run or y2-y1/x2-x1 (change in y over change in x)
Y-intercept (I'm assuming you mean y-intercept instead of y axis) = if there's a graph, find where the line intersects the y axis, if there isn't a graph, use y=mx+b to solve for b, the y-intercept.
Hope this helps!

Mr. Villamayor rented a construction crane for five hours and a backhoe for seven hours. The total amount he paid is less than Php 9,000. Suppose the hourly rate for the crane is Php 800. What is the maximum amount he paid for the backhoe to the nearest hundreds?
Answer:
Let 7x be the rent paid for backhoe for seven hours.
Step-by-step explanation:
Keyword: maximum amount, the most
Inequality symbol: ≤
(800 × 5) + 7x ≤ 9,000
4,000 + 7x ≤ 9,000
7x ≤ 9,000 - 4,000
7x ≤ 5,000
7x ÷ 7 ≤ 5,000 ÷ 7
x ≤ 714.29
To the nearest hundreds:
x ≤ 700
ANSWER: The maximum rental fee per hour of backhoe is Php 700.00 (rounded off to the nearest hundreds).
To check if he paid less than 9,000 for the total rent:
(800 × 5) + (700 × 7) < 9,000
4,000 + 4,900 < 9,000
8,900 < 9,000 (True)

The area of on field is 16 acres, the area of the second field is 1 1/4 times bigger. A barn of wheat on the first field makes up 37 1/2 thousands pounds per acre, and on the second 1 2/15 as much per acre, how much more was gathered on the second field than the first?
Answer:
250 thousand pounds
Step-by-step explanation:
Given that:
Area of field 1 = 16 acres
Area of field 2 = 1 1/4 bigger than field 1
Barn of wheat on field 1 = 37 1/2 thousands pounds per acre
Barn of wheat on second field = 1 2/15 as much as field one per acre
Total pounds gathered on field 1 :
37 1/2 * 16 = 600 thousand pounds
Area of second field :
1 1/4 * 16 = 5/4 * 16 = 20 acres
Barn of wheat per acre = 1 2/15 * 37 1/2
= 17/ 15 * 75/2 = 42 1/2 thousand pounds per acre
Total = 42 1/2 * 20 = 850 thousand pounds.
850 - 600 = 250 thousand pounds

Answer:
10) It increased by appoxamately 17%.
11) 255 decreased by 20%
12) 15 increased by [tex]66\frac{2}{3}[/tex]%
13) $9,450
14) $149.8
15) $238.5
Step-by-step explanation:
10) 170 is greater than 150 by 25. 25 is [tex]16\frac{2}{3}[/tex]% of 150, so it increased by appoxamately 17%.
11) 225 is decreased by 45. 45 is 20% of 100, so 255 decreased by 20%
12) 15 is increased by 10. 10 is [tex]66\frac{2}{3}[/tex] of 15, so 15 increased by [tex]66\frac{2}{3}[/tex]%
13) 5% of 9,000 is 450. 450 + 9,000 is $9,450
14) 7% of 140 is is 9.8. 140 + 9.8 = $149.8
15) 6% of 225 is 13.5. 225 + 13.5 = $238.5

THE LENGTH AND THE BREADTH OF A RECTANGULAR PARK ARE IN THE RATIO 5 : 2. IF ITS PERIMETER IS 168m, FIND ITS LENGTH AND BREADTH.
(STEP BY STEP PLZ) (HOPE U ENJOY IT)
Answer:
Length = 60m, breadth = 24m
Step-by-step explanation:
Let the length of the park be 5x and the breadth 2x.
5x+5x+2x+2x = 168
14x = 168
x = 168 ÷ 14
x = 12
Length (5x) = 12 × 5
= 60
Breadth (2x) = 12 × 2
= 24
Answer:
Length = 60m, breadth = 24m
(100)+ (-55) + (-90)
Answer:

Finally you get -45
9 is 3% of what number? Which proportion matches this information?
Answer:
B
Step-by-step explanation:
3% = 3/100
So we can eliminate the first answer.
The proportions have to match each other so the number nine should be above and thus the x has only the option of being under it.
As a result, we eliminate the third answer and remain with one reasonable answer
