Answer:
B -4
Step-by-step explanation:
-1.5(4 - r) = -12
Distribute -1.5.
-6 + 1.5r = -12
Add 6 to both sides.
1.5r = -6
Divide both sides by 1.5.
r = -4
Your answer is -4.
Answer:
r = -4
Step-by-step explanation:
-1.5(4-r)=-12
Divide each side by -1.5
-1.5 / -1.5 *(4-r)=-12 / -1.5
(4-r) =8
Subtract 4 from each side
4-r-4 = 8-4
-r = 4
Divide each side by -1
-r/-1 = 4/-1
r = -4

Mac waters plants for his neighbors when they are away. He graphed several points on a coordinate grid to represent the watering. The x-axis represents the number of plants he has watered in a given day, and the y-axis represents the number of gallons of water he has used to water them. Which point on his graph represents a different ratio of gallons of water to plants than the other points?
A. (16, 4)
B. (8, 2)
C. (24, 8)
D. (48, 12)
Answer:
Step-by-step explanation: 50 km is 36.1 km more than 13.9.
Hope this helps !
-Carrie
Step-by-step explanation:
The correct option is Option C: the point (24,8) shows different ratios of gallons of water and plants from other points.
What is the ratio?The ratio is the representation of the fraction where this fraction is represented by the : symbol.
Given in the question number of plants that he watered every day is represented on the x-axis in the coordinate grid.
The number of gallons that he waters every day is represented on the y-axis in the coordinate grid.
We have to check the ratio of the y coordinate and the x coordinate is different from other options.
By checking all the options
Option A: (16,4) ratio of gallons of water and plants that are watered is 4/16= 1/4= 1:4
Option B: (8,2) ratio of gallons of water and plants that are watered is 2/8= 1/4= 1:4
Option C: (24,8) ratio of gallons of water and plants that are watered is 8/24= 1/3= 1:3
Option D: (48,12) ratio of gallons of water and plants that are watered is 12/48= 1/4= 1:4
By analyzing all options, Option A, B, D has a ratio 1:4. and Option C has a ratio 1:3.
Therefore the correct option is Option C: the point (24,8) shows different ratios of gallons of water and plants from other points.

Brainiest If Correct + 50pts ---The cylinder with base radius 5 and height 12 is inscribed in a right rectangular prism. Find the total surface area and the volume of the prism.
Answer:
SA = 680 units^2
V =1200 unit^3
Step-by-step explanation:
If the radius is 5 then the diameter is 2r = 2*5 = 10
The height would remain the same
Surface area of a prism is given by
SA = 2 (lw+lh+hw)
l =d = 10 w = d = 10 h = 12
SA = 2 ( 10*10 + 10 * 12+ 12* 10)
SA = 2( 100+120+120)
SA = 2(340)
SA = 680 units^2
V = l*w*h = 10*10*12 =1200 unit^3

the tailoring?
A $16.04
B $20.37
C $27.16
D $29.62
Answer: $29.62

9.25 * 1 = 9.25
So, 20.37 + 9.25 = 29.62
Answer:
D

Garden table and bench cost $554 combined. The Garden table cost $96 less then the bench. What is the cost of the bench?
Answer:
$325
Step-by-step explanation:
Let x be the cost of the bench.
Therefore, x + (x-96)=554
2x-96=554
2x=650
x=325
Answer:
The bench cost $229 and the garden table costs 229 + 96 = $325
Step-by-step explanation:
let the cost of the bench = x
the cost of the garden table = x + 96
x + (x + 96) = 554
2x + 96 = 554
2x = 458
x = 229

The value of the expression is -100/3.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
- (-4) (-6) - 3/5 (10 + 15) - 1/3
Simplifying the expression.
= 4 x -6 - 3/5 x 15 - 1/3
= -24 - 3 x 3 - 1/3
= -24 - 9 - 1/3
= (-72 - 27 - 1)/3
= -100/3
Thus,
The value of the expression is -100/3.

Chris buys 8 more Ninja Turtles than Star Wars action figures. The Ninja Turtles cost $7 each and the Star Wars cost $9 each. Write an expression to model this situation, using S for Star Wars.
Answer:
Total Cost, C=$(16S +56)
Step-by-step explanation:
Chris buys 8 more Ninja Turtles than Star Wars action figures.
Cost of each Ninja Turtle = $7
Cost of each Star Wars = $9
Let number of Star Wars bought = S
As per question statement, number of Ninja Turtles bought = S+8
Cost of 'S' number of Star Wars = Number of Star Wars bought [tex]\times[/tex] cost of each Star Wars
Total cost of Star Wars bought = S [tex]\times[/tex] 9 or $9S
Similarly, Cost of 'S+8' number of Ninja Turtles = Number of Ninja Turtles bought [tex]\times[/tex] cost of each Ninja Turtles
Total cost of Ninja Turtles bought = (S+8) [tex]\times[/tex] 7 or $(7S +56)
Total Cost of the purchase = Total cost of Star Wars Bought + Total cost of Ninja Turtles bought
Total Cost of the purchase, C = 9S + (7S +56)
[tex]\Rightarrow C=\$(16S +56)[/tex]
Answer:
C=$(16S +56)

Consider the y - intercept and slope of the following graph;
[tex]y - intercept = ( 0, 3 ) In Other Words - 3\\slope = rise / run = 2 / 3, In Other Words- slope = 2 / 3[/tex]
Now let us formulate an equation given this information;
