Roman buys seed packets for the school garden. One packet of radish seeds costs $1.75. One packet of tomato seeds costs $2.50. L
HACTEHA [7]
Answer:

C. t=23,r=9 .

Step-by-step explanation:

Let r represent the cost of one packet of radish seeds and let t represent the cost of one packet of tomato seeds.

Roman spent $62.75

This implies that,

1.75r+2.5t=62.75...eqn1

Roman bought 32 packets of seeds and one packet of radish seeds costs
$ 1.75.
One packet of tomato seeds costs $ 2.50.

This implies that,

r+t=32...eqn2

Using guess and check means we substitute into the given equation.

A) We substitute t=8,r=24 into both equations.

1.75(8)+2.5(24)=62.75...eqn1

14+60\ne 62.75...eqn1

8+24=32...eqn2

Both equations are not satisfied.

B)

We substitute t=9,r=23 into both equations.

1.75(9)+2.5(23)=62.75...eqn1

15.75+57.5\ne 62.75...eqn1

9+23=32...eqn2

Both equations are not satisfied.

C)

We substitute t=23,r=9 into both equations.

1.75(23)+2.5(9)=62.75...eqn1

40.25+22.5 =62.75...eqn1

23+9=32...eqn2

Both equations are satisfied.

Hence the solution is,

t=23,r=9

D) We substitute t=24,r=8 into both equations.

1.75(24)+2.5(8)=62.75...eqn1

42+20\ne 62.75...eqn1

24+8=32...eqn2

Both equations are not satisfied.

What is the value of y−5x−3for x = 2 and y = -4
arlik [135]

Answer

-17


<u>Explanation</u>

y−5x−3 for x = 2 and y = -4

We solve this question by substituting the values of y and x.

y−5x−3 = -4 - 5(2) - 3

             = -4 - 10 -3

             = -14 - 3

            = -17

What number is obtained by increasing by 36 50%​
Rudik [331]

Answer:

54

Step-by-step explanation:

The given number to be increased = 36

The percentage by which the number is increased = 50%

In increasing a number by a percentage, we find the value of the percentage increase of the number and add to the number as follows;

50% of 36 + 36 = 50/100 × 36 + 36 = 54

Second method

The find the number obtained by increasing a number by a given percentage 'x', we add 100 to the give percentage and multiply the result by the number and hen divide the final result by 100 as follows;

36 increased by 50% = (100 + 50) × 36/100 = 54

A triangle T is bounded (on three sides) by the lines x = 6, y = 0, and y = 3 2 x. A rectangle of width w is inscribed inside T.
Viktor [21]

Answer:

33.85 units^2

Step-by-step explanation:

you must first draw the triangle on the plane using the equations (see

attached file), you will have a right angle triangle with a height of 192 and a base of 6.

then you calculate the angle with the tangent function = 88.21

Then you use the small triangle to find the value of a (see attached file).

Finally, you propose an equation for X to find one of the sides of the triangle, once you have x squared it, and you already have the area,
