Answer:

0=3 1=5 3=9

Step-by-step explanation:

Given:

Consider the equation is:

[tex]5m-2m+3=-1+12[/tex]

Some steps of the solution are given.

To find:

The next step of the solution.

Solution:

Step 1: The given equation is:

[tex]5m-2m+3=-1+12[/tex]

Step 2: Simplifying right hand side.

[tex]5m-2m+3=11[/tex]

Step 3: Simplifying left hand side.

[tex]3m+3=11[/tex]

These steps are already given. So, the next step is:

Step 4: Subtracting 3 from both sides.

[tex]3m=8[/tex]

Therefore, the correct option is (b).

Answer:

Answer:

x=54, acute scalene triangle

Step-by-step explanation:

1st Question:

Triangle SRT has two congruent sides, making it an isosceles triangle.

In isosceles triangles, the two base angles are congruent.

This means that in the question, ∠SRT equals ∠STR, so let's call them both x.

The sum of the interior angles of a triangle add to 180, so

∠RST+∠SRT+∠STR=180

Substitute ∠RST for 72 and ∠SRT+∠STR for x

72+2x=180

2x=108

x=54

2nd Question:

Again, using the sum of the interior angles of a triangle, we can say

42+88+∠DFE=180

∠DFE=50

All the angles in the triangle are less than 90°, meaning they are all acute. Also, none of the sides are labeled as congruent, so it is an acute scalene triangle

Answer:

R'={(3,4)(4,5)(5,6)}

Step-by-step explanation:

R={(4,3)(5,4)(6,5)}

R'={(3,4)(4,5)(5,6)}

Answer:

d ... or c

Step-by-step explanation:

Answer:

Step-by-step explanation:

As the man was 62 years old 18 years ols so first we have to add 18 to 62

=80

So, now we have to find his age after 6 years so we should just simply add 6 to 80

=86

He will be 86 years old.

Hope this helps you :-) :-)

Answer:

d.

Step-by-step explanation:

Answer:

D. $892.50

Step-by-step explanation:

First we find out the interest:

850 * 2.5% = 21.25

Since this is 2 years we multiply the interest by 2.

21.25 * 2 = 42.50

Now we add the interest with the amount borrowed.

850 + 42.50 = $892.50

So, the answer is $892.50 in total.

Hope this helps! :)

25-2t=0

2t=25

t=25/2=12.5 hrs.

Answer:

Step-by-step explanation:

12 hours and 30 minutes because every hr is 2 degrees so 30 minutes is 1 degree

Step-by-step explanation:

[tex]slope = \frac{\triangle \: y}{\triangle \: x} \\ = \frac{(7 - 2)}{(6 - ( - 5))} \\ = \frac{5}{11} \\ slope = (5 ,11)[/tex]

Answer:

10ft^2

Step-by-step explanation:

16in/4in =4ft for the length

10in/4in= 2.5ft for the width

so 4ft x 2.5ft =10ft^2

so 10ft^2

Answer: A) multiply the input by 6.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

12÷2=6

36÷6=6

48÷8=6

54÷9=6

72÷12=6

so that means you have to multiply the input by 6.

Answer:

Step-by-step explanation

width is 9. length is 14

Answer:

94 cups

Step-by-step explanation:

5 gals = 80 cups; 14 cups + 80 cups = 94 cups

Step-by-step explanation:

Explanation:

First, we must solve the equation for y to determine the slope: y = 2x + 3/2

By looking at the coefficient in front of x, we know that the slope of this line has a value of 2. To fine the slope of any line perpendicular to this one, we take the negative reciprocal of it:

slope = m , perpendicular slope = – 1/m

slope = 2 , perpendicular slope = – 1/2

Answer:

the slope would be -5/2

Explanation:

the perpendicular slope of a line is the negative reciprocal and the negative reciprocal of 2/5 is -5/2

Answer:

the area of the hexagon is 68 cm²

Step-by-step explanation:

Let us observe the image a little, we can find the area of the hexagon equals to the area of the large rectangle minus 4 small triangles surrounding the hexagon. The area of the rectangle is 8 × 12 is 96 cm². The area of 1 small triangle is 4 × 3.5 ÷ 2 = 7, there are 4 triangles, so the total area is 4 × 7 = 28. So the hexagon's area is 96 - 28 = 68 cm²

Hope this will help❤️

Answer:

Area of new garden = 800 ft²

Step-by-step explanation:

Given:

Old fencing = Parameter of old garden = 60 ft

Area of old garden = 200 ft

Find:

Area of new garden if Parameter of new garden is 120 ft

Computation:

Assume;

Length of old garden = l

Width of old garden = b

So,

2[l + b] = 60

l + b = 30

l = 30 - b

Area of old garden = 200 ft

l x b = 200

So,

(30 - b)b = 200

b² - 30b + 200 = 0

b² - 20b - 10b + 200

b(b-20) - 10(b-20)

(b-20)(b-10)

So,

Width of old garden = 10 ft

Length of old garden = 20 ft

New parameter is double

So,

Width of new garden = 10 x 2 = 20 feet

Length of old garden = 20 x 2 = 40 feet

Area of new garden = l x b

Area of new garden = 20 x 40

Area of new garden = 800 ft²

Answer:
