Answer:

Step-by-step explanation:

d=m+a/n

Firstly, we multiply n to get rid of it by both sides. Since n is dividing a.

d=m+a/n

*n *n

dn=m+a

-m -m

a=dn-m

Solve for A by simplifying both sides of the equation, then isolating the variable.

Answer: A = dn - mn

Each lenght is in metres Calculate DC

Gnom [1K]

Step-by-step explanation:

ED is greater than BC

the line from B to ED ^ (which i drew ) the point it touches ED name it X. so EX will be 2 ( ED-BC)(6-4).

then u have a triangle. EX, XB and EB.

you have length of EX(2) and u have hypotenuse. so u can calculate XB using Pythagoras theorem.

15.1²=2²+XB²

15.1²-2²=XB²

224.01=XB²

XB=14.97

since XB and DC are parallel ( a rectangle is forming XBCD) so DC is also 14.97

What’s three points that satisfy the system of inequality’s of 4x+6y<24

Vlada [557]

Answer:

(0,0), (1,1), (2,2)

Step-by-step explanation:

When testing to find possible points in situations like this, I always start by testing with the origin point (0,0).

In this case:

4x+6y<24 ==> 0 + 0 < 24 TRUE, it satisfies the inequality.

We then try with (1,1):

4x+6y<24 ==> 4 + 6 < 24 TRUE, it satisfies the inequality.

And with (2,2):

4x+6y<24 ==> 8 + 12 < 24 TRUE, it satisfies the inequality.

10. The sum of two numbers is 13 more than twice the first number. Their difference is 14 less than the second number. Find each

Lynna [10]

The sum of two numbers is 13 more than twice the first number:

x + y = 2x +13

x - y = y - 14

solve the system of equations:

x - (x + 13) = (x +13) - 14

x = -12

y = 1
